A fire extinguisher. You probably won't ever use it, but if you do need it someday, it will be well worth the 20 bucks.

EDIT: Yes, you can get a decent one for the home for under $20.

EDIT PART 2: Aaaaahhhhh thanks for the gold! You just made my night! :D

u/Jondayz · 210 pointsr/LifeProTips

This one is on sale on Amazon right now for 63% off, $20. It has a digital read out and good reviews. I just bought one. I know you have Prime, order it you lazy ass.

u/Old_Deadhead · 106 pointsr/tifu

Vapes aren't actually vapor, they're aerosol. They actually sell aerosol sprays for testing smoke detectors and fire alarms.

u/dirtyuncleron69 · 94 pointsr/cars

That's why you keep a fire extinguisher in your car. It's really an awesome idea. The dry chemical kind are what they use at race tracks most of the time, and I can say from experience your car will usually run after a bit of cleaning (had a fuel line barb work its way out of a carburetor).

My one buddy told me, "You'll never think you need it until you're watching your car burn and standing there with your dick in your hand."

u/EmAreDubs · 43 pointsr/Columbus

Yikes. Always make sure your hot water heater and furnace are properly vented to outside, and remember that a $25 device can save your life. For maximum peace of mind, place a carbon monoxide detector in the main living area and in each bedroom.

u/Clapbakatyerblakcat · 27 pointsr/educationalgifs

Have an up to date fire extinguisher in your kitchen.

Also, have fire extinguishers in your hall closet, bedroom, car, girlfriend’s car, etc.

Give them to family as stocking stuffers

They are small and cheap and can stop a shitty situation from turning catastrophic.

u/AreasonableAmerican · 23 pointsr/microgrowery

Glad he caught it in time! I have a heat triggered fire extinguishing ball in my grow closet for this very purpose- it may be what your friend needs:

Elide Fire Ball, Self Activation Fire Extinguisher, 2018 New Version , Boat Extinguisher, Car Extinguisher, Fire Safety Product, Elide, 5 Year warranty

It may ruin your plants, but if it saves the house...

u/moocow2024 · 21 pointsr/3Dprinting

Just put one of these in the corner of the enclosure ;)

u/PeaceOfTheHighLife · 19 pointsr/WTF

This is what happens when water instantly turns to steam and explodes out with a surprising amount of force taking the oil and flames with it.. Cover it and remove it from heat if you can. Small oil fires can be put out with baking soda, and extinguish large oil fires with a powder fire extinguisher if need be..

Also, if you don't have one, even a small to medium sized powder fire extinguisher, something.. Go buy a a huge box of baking soda right now, set it someplace accessible, and be ready to tear that open if need be.. Then go on amazon and get yourself a powder fire extinguisher for probably sub $30 (or hey, when you need to make free shipping) and be safer for it.

Then, never, ever, ever! Put water or some other liquid that boils at a lower temperature than oil, into hot oil and not be anything other than ready to put out a grease fire.. Keep a small baking soda by your stove.. Why not.. Be ready.. Adding wine to that chicken you've been frying in a little too much oil? Oh no, you burned your house down, no you didn't, cause you had baking soda at the ready!

Oh no, it's not enough! Not in your house, you're the Elsa of baking soda! Tear off the top and let it go! Cover the flames and everything around it, let's face it, you're cleaning the kitchen at this point. And besides, the baking soda helps absorb the oil that is now everywhere.. Get a mop, it's time to get cleani--

But wait, the beast, she crackles forth.. But you.. You are prepared.. You must attack the source! No problem! For you are armed with the mightiest and the highest reviewed of all the $30 amazon powder fire extinguishers.. Go forth, pull pin, and let rip at the center of all the flames, the source, and start working your way out.. Cover everything..

If it burns, shoot it..

Smile, victory is yours.. Call your insurance, call your local cleanup crew.. Laugh after realizing you no longer have to clean the kitchen..

TL;DR Get a big box of baking soda and be ready to pour it everywhere! You're fighting a grease fire and IT WILL BURN DOWN YOUR ENTIRE LIFE, if you let it. Also get the best reviewed $30 powdered fire extinguisher on amazon, right now.. Seriously, you'll probably save lives with this some day, or not quite burn down as much of your house...

Oh look! A $30 Highly-reviewed Kidde FA110 Multi-Purpose Powder Fire Extinguisher and a ridiculously long hyperlink so you notice it and buy one because, Hey!!!!!! This!!! THIS WILL SAVE YOUR LIFE and your most valued possessions!!!! And, free shipping over $35... BUY IT! BE SAFE!

Also, for those who have them, you rock, but you should check now to see if yours has expired and replace if need be!!!

AND ABOVE ALL ELSE!! If a fire ever seems out of control, or starts out that way, call the fire department IMMEDIATELY, and fight the fire if you can, flee if you can't.. Your life is more valuable than your belongings.

u/MrTooNiceGuy · 19 pointsr/Frugal

This one isn't cheap, and it's not what the OP suggested, but it's the bare minimum I would suggest.

Unless you've got proper (also annually refreshed) training, anything less than 5 pounds is bordering on insufficient. Especially in a panic situation.

u/RepostFromLastMonth · 19 pointsr/legaladvice

I know you're going to get a Carbon Monoxide detector, but I also recommend (just to keep things compact) getting a combination CO/Smoke detector. You can get multi-packs as well to put in different areas of your house. You should have one in the bedroom, hallway, kitchen, etc... depending on size of the place.

u/thepatman · 10 pointsr/HomeImprovement

I standardized on Z-Wave and Zigbee stuff - more Z-Wave than Zigbee. I used a SmartThings hub in this house, and so I used these sensors. I put one under each sink in the house, plus one near the main stack in the basement and the hot water heater.

If I could, I'd also recommend adding a couple of HA CO/smoke sensors. Again, z-wave for me, but I used this First Alert model. If I get smoke or CO at any time, it alerts my phone, and I'm a huge fan of that.

One note on those smoke detectors - some places have highly specific laws on what smoke detectors you must legally have, and these do not match code where I live. I run double sets - one set that matches code and then this set for the HA side. It's not a problem to have more smoke/CO detectors, and it's a cheap and potentially life or property saving upgrade.

I just want him and everyone who takes advantage of musicians/artists to go away.

Or be a human being and take some of the money you are collecting/stealing and buy $200 worth of fire prevention equipment from Amazon. A fire extinguisher is $20. A fire blanket is $12. Our safety is a collective effort. Nobody has any excuses especially those who are profiting from this community.

u/engine__Ear · 9 pointsr/Damnthatsinteresting

In short: yes! You do so by introducing a chain breaking chemical. Others have mentioned halon as a good example of this. So is Tundra which in a little aerosol can fire extinguisher with a potassium containing chemical that works by the same mechanism: breaking the chemical reaction chain.

If you look up the combustion chemical reaction, it is generally something like CH4 + 2O2 = CO2 + 2H2O (roughly for methane). However, that reaction is just the net sum of what's really happening.

Big clunky CH4 molecules dancing around don't commonly bump into other big O2 molecules. And when they do, it's highly unlikely everything will get rearranged perfectly to make CO2 and H2O. Instead, a bunch of little steps happen in the middle. A chain reaction of steps called a reaction mechanism. We know this by understanding rates of reactions.

Since we understand roughly how reaction rates work, we also know which ones are fast and therefore happen much more often. In combustion, the first ones are called INITIATION REACTIONS where those big clunky molecules break apart (decompose or dissociate by some ignition event like a spark) into smaller, more reactive stuff. An example is O2 = 2O. One oxygen molecule makes two oxygen radicals. That means one molecule moving around hitting things is not two running around hitting things over twice as often.

Now we have some big molecules and radicals dancing around. Something to note is that those molecules we start and end with (CH4, H2O, CO2, H2O) are relatively stable compared to those radicals like H, OH, O, etc. Those radicals are unstable forms of this atoms so they want to bump into other molecules, make or break bonds, and reach something more stable.

So when a big more stable molecule runs into one of those little reactive radicals we make more things happen. An example is O2 + H = OH + O. So we started with one unstable radical and ended up with two unstable radicals running off to react with more molecules. This is called a BRANCHING REACTION and it's how the chain reaction accelerates. There are also PROPAGATION REACTIONS where you start and end with the same number of radicals so you rearranged bonds but generally speaking didn't speed up or slow down he overall chain reaction.

Finally we have TERMINATION REACTIONS where we end up with fewer radicals than we start with. An example would be H + OH + M = H2O + M (ignore that M for now, just means the reaction needs a helper molecule to proceed so it will happen more at higher pressures). We start with two reactive radicals and end with one.

This is where halon or that Tundra stuff come in. They react very fast with radicals that develop early in the reaction, like Halon with H radicals, so you overwhelm the chain reaction with TERMINATION REACTIONS before it can keep going. Kill the chain and you kill the combustion, even with fuel oxidizer and heat there. As long as that radical scavenging chemical remains to keep breaking the chain, the combustion won't proceed.

Google combustion reaction mechanisms to learn more.

u/MisterQuimper · 9 pointsr/LifeProTips

Gonna risk the /hailcorporate tag but now is a good a time as any to stock up on CO detectors. MA code mandates at least one for every floor in your house (seems a bit overkill since CO doesn't rise) but one near your furnace is a bare minimum


u/-weinerbutt- · 9 pointsr/ProtectAndServe

That is the one I have in my car and my house.

I got one after a father and son in my city died while waiting for their car to warm up. They didn't know they had a leak in their exhaust and the CO doesn't smell like exhaust. It has no smell.

u/crazyguyonabike · 9 pointsr/preppers

I got about 60 of the 1 lb canisters and 2 of the 20 lb tanks in one of these deck boxes:

The two 20 lbs go in a corner each, and then the 1 lbs are arranged around them on the floor. Then I cut a piece of plywood in the shape of the inside of the deck box, with cutouts for the two 20 lb tanks, to make a second story which is laid on top of the first layer of 1 lb canisters. Then I get a second layer of the 1 lbs in there, and it's about 60 of those plus 2 x 20 lbs, makes approx 100 lbs total, give or take. It's been a couple of years now, and they seem to last very well in there. I also keep some adaptors and hoses so I can hook the 20 lbs up to the Little Buddy heaters and the propane stove etc. I keep the deck box on the lower deck behind the house in a spot under the upper deck so that it doesn't get a lot of direct sunlight. I think it's probably better if it doesn't get too hot. Also, if anything leaks, then propane is heavier than air, so you want the path to be away from the house, not down into your crawlspace or basement. Finally I recently got a "WARNING PROPANE" sticker (from Amazon) for the firemen should there ever be a fire around my house. They should know about that amount of propane, for obvious reasons.

One last thing: Consider getting a couple of battery powered carbon monoxide detectors, just for peace of mind, e.g.

u/RexBearcock · 8 pointsr/Firefighting

Fire extinguishers come in different types. A dry chemical extinguisher rated for A-B-C (3 most common) would handle nearly anything you may need in a standard house. Probably get one in the 5lb range. You'll probably want more than one depending on size of the house, one in the kitchen, one in the garage, for example

EDIT: for safety, make sure you install a carbon monoxide detector.

u/Zigian · 7 pointsr/3Dprinting

I run mine unattended, but I have a fire ball and an automatic fire extinguisher to snuff the flames in the event something goes wrong. The fireball is nice because you can put it just about anywhere, including inside an enclosure if you plan for it.

u/ClassyUser · 6 pointsr/Dallas

Just want to throw this out there, for $50 you can get an explosive gas alarm. As easy to install as a night light.

Home Depot


It’s different than a carbon monoxide alarm, that detects a byproduct of burning the natural gas that can kill you. Many smoke detectors will also detect carbon monoxide. The explosive gas sensor is a metal oxide sensor designed to detect natural gas (methane) or propane.

u/greenbuggy · 6 pointsr/Denver

They are pretty cheap though. I bought a house in Firestone last year and you can get a portable explosive gas detector for inside of fifty bucks - no experience with this one but it's on Amazon for $37 they also sell one that plugs into the wall and also detects carbon monoxide

Biggest problem with the gas straight out of the well is that it has no detectable odors - after it's processed the refinery adds methyl mercaptan to make it stink like sulphur. So you would know if your natural gas line to your furnace or water heater were leaking, but without a detector you probably wouldn't know about something odorless silently seeping into your basement.

I personally have to wonder if the "problems" that were being repaired by installing a new water heater were directly caused by excess heavier gas displacing air enough to cause problems with the pilot light on the water heater.

u/Dirty_Old_Town · 6 pointsr/Louisville

You can get one for $15 online. Worth it.

u/rabidstoat · 6 pointsr/news

I just bought this one after reading this. (Not an affiliate link, but using the smile URL for the charity donation.)

u/OMCBackdraft · 6 pointsr/hobbycnc

Smoke detector might give you lots of false alarms based on the nature of how they work and that dust collection isn’t 100%.

You put a smoke detector in there and you will end up taking it out. There are however heat detectors, they can be a set temp or a rate-of-rise type and they don’t care about dust for activation. Just as an example.

Someone smarter than me could probably tell you how you could to integrate it with a raspberry pi and a relay, or maybe even a more simple method??

u/Arkham80 · 6 pointsr/Pikabu

u/HeloRising · 5 pointsr/3Dprinting

Well yes, but actually no.

In all seriousness, the vast majority of machines shouldn't present problems if you don't start opening up cases and poking around and making ill-advised modifications.

Major brand name machines are generally pretty reliable if run in-spec. There are occasional issues (See the recent controversy with the Ender 3's bum connectors) but for the most part the risk is minimal.

That said, it's a mechanical device that works with high temperatures and generally flammable material, it's inevitable that there are going to be problems.

I have my printer set up with a metal beam over the bench and I stuck one of these above the printer. I highly recommend them.

A lot of people like these but they're not a great idea because of how they function. They explode and throw their fire suppressant all over the area but the explosion is basically just a small firecracker and can throw burning debris around a room.

The overhead ones that I posted will just pop open and dump their contents down so they're perfect for positioning over a printer.

u/Esc_ape_artist · 5 pointsr/3Dprinting

You could print a holder for a couple of these and suspend them over an enclosed printer.

u/Veighnerg · 4 pointsr/tifu

Just buy a Propane/Natural gas detector and plug it in near the kitchen area. It will help you avoid any situation like this in the future. Something such as this may work

u/brewerdoc · 4 pointsr/Homebrewing

Carbon monoxide can be produced by any fire. If you are heating anything by "gas" in your house be it propane, butane or whatever, you should have a carbon monoxide monitor. You can find them for about $20-30 dollars. amazon link to a CO detector.

Symptoms of carbon monoxide poisoning include:
-Dull headache
-Shortness of breath
-Blurred vision
-Loss of consciousness

I admit a couple of people to the hospital a year who get carbon monoxide poisoning. It's never pretty and the treatment is limited. Hyperbaric oxygen is one of the treatments but many hospitals do not have this option so they resort to putting a mask on the person who inhaled the poison till they can call other hospitals till they find one that has the hyperbaric oxygen treatment.

Even if you have a "gas" furnace, water heater, stove or brewery in your house you should have one of these. The molecule has no smell and by the time you notice the effects its usually either too late and its very advanced.

u/starbot1 · 4 pointsr/smarthome

u/lbmn · 3 pointsr/OffGrid

> wanted to be able to run fridge and laptop for a week at least before on solar before I have to turn on the engine and drive to my next spot

A normal laptop (10-90W), a small fridge (100-400W), and a room heater (900-1500W+) are orders of magnitude apart. The only time I've heard of anyone using an electric heater when camping was when he had an over-abundance of gasoline-electrical generator output, but one probably wouldn't want to run a generator at night due to noise.

> do you think these buddy heaters are save enough for children to be in the same room

A lot of people use propane heaters in RVs. Of course having a CO (Carbon Monoxide) detector and a fire extinguisher on hand is a must, even if burning a single candle. That aside, the most important thing is to assure adequate ventilation. Extra super-safety measure: set an alarm every 2 hours the first night to walk around the room and make sure the air is fine, nothing is overheating, etc.

When it comes to the possibility of leaks, propane is generally safer than natural gas, because: (1) You can smell it. (2) Propane vapors are heavier than air, so being higher off the floor is an added safety benefit (in addition to being more heat-efficient). (3) Buddy Heaters self-ignite automatically, so there's no chance of turning on the gas and forgetting to light the flame. You can get a propane leak detector as well (a separate function from CO detection, but possible to have both in one device).

I don't know anything about kids, but I don't think they are inclined to touch things that are very obviously very hot. I guess using some sort of a cage (around the heater, I mean, not the kids) would add an extra level of safety...

u/Greeneee- · 3 pointsr/vandwellers

It's very unlikely that anything goes wrong. But if it does, your tapestry would go up in flames, or you'd just pass in your sleep due to lack of oxygen.

Plenty of people do it, its still a gamble. Personally I'd get a nice carbon monoxide and gas alarm alarm if running a propane heater all night.

u/Eddirter · 3 pointsr/Calgary

$30 -

At the 2100ppm level the fire department measured an adult has over an hour to get out to clean air, a child has less, but that alarm would have certainly given a heads up, especially if you hear all of your neighbours having them go off in the hallway at the same time.

u/steezy13312 · 3 pointsr/preppers

Good idea, but not how to execute. The smoke can actually damage the sensor.

That's great!

But, the rest of us aren't so confident about the Anet A8 seeing how there are multiple examples of them catching fire.

#1 2017

#2 2017

#3 2017

#4 2018

That's me taking 5 minutes. Actually I spent more time writing this than researching this. An exhaustive search would probably yield more and these are just the ones people are telling us about.

Maybe they can be made safe, but that needs to happen in the factory, not after the fact by the consumer who probably isn't an electrical engineer. You're not an electrical engineer are you?

Disclaimer: I'm not an expert. Take my advice at your own risk.

I don't know what's causing these fires. But, I've heard mention of mainboards and PSU's. You should probably take the task of heating off the mainboard and put it onto external mosfets for the hotend and the hotbed. You might also want to replace the factory power supply (PSU) with something more robust. As long as the A8 is 12 volts I'd probably suggest an ATX power supply conversion if you're handy with a soldering iron and feel confident you can do it. ATX power supplies come with a number of built-in safety features. Here's a wiki on choosing a PSU.

You might also want to add some basic fire suppression to your print area. This maybe would stop a fire, but it's not going to stop an electrical short creating heat and therefore acting as an ignition source. It might give you more time to react in the case that a fire does start.

Edit: I couldn't find the rating on the rangehood fire extinguisher so, this ball extinguisher that is ABC rated might be a better option if you can figure out how to suspend it above your printer which shouldn't be too hard as it comes with a metal stand.

I would definitely add a fire extinguisher nearby where you print.

Then add a fire alarm above your printer and in the adjacent room.

This is not just advice for you, but it's advice for anyone. I've done all three of the above suggestions. I've add the stove rangehood fire extinguisher. I've wall mounted a fire extinguisher in the adjacent room. I've also add two fire alarms, one above my printer and another in the adjacent room.

Be safe my friend and heed the warnings these multiple fires are broadcasting.

u/x9x9x9x9x9 · 3 pointsr/3Dprinting

I was thinking about this today. But I had an idea. What if you made a holder for one of these at the top of the enclosure?

u/FencingNerd · 3 pointsr/3Dprinting

If you're clever you could rig up an Arduino or Raspberry Pi as a smoke detector.

Use a relay to control the power supply to the printer, if any smoke is detected the Arduino would immediately cut the power to the printer. At that point, the most critical thing is making sure there's minimal flammable material around the printer.

Alternatively, mount a fire ball above the printer in the enclosure.

u/captainstormy · 3 pointsr/personalfinance

Some things I know I forgot:

  • Fire Extinguishers. I had one in my one bedroom apartment in the kitchen, which was only about 10 steps away from anywhere else in the apartment. But houses are bigger, you need more. I keep one in the kitchen, garage and one in the basement near your electric panel and HVAC. Make sure the kitchen & garage ones are Class B. The basement one should be class C. I just played it save and bought these, they are class A,B & C.
  • Light bulbs, your going to need so many more than your used to. My house has ceiling mounted lights in every room (not every house does). My house has over 48 light bulbs in it just for those ceiling mounted lights. I'm a huge fan of these light bulbs. Just a bit over $2 a bulb, very bright, nice clean daylight color and LED. Can't be beat.
  • Also on the light bulb thing, think of any you need that aren't your standard bulb. Ceiling fans(Some use Candalabra size, some use normal), flood lights, etc etc. Personally I make sure every bulb in my house is the same color of light too. It really annoys me when I walk into a friends house and they have like 4 different color light bulbs in one room. That may just be my OCD though.
  • You may need a basic tool box if you don't already have one. There isn't any more calling maintenance when a small job needs done. It's either you do it, or pay a handyman to do it for you. And you'll go broke paying a handyman for everything. YouTube will become your friend to learn things you don't know. You don't have to start off super fancy. An assortment of sizes of Philips and Flat Head Screwdrivers. Needle Nose and regular pliers. A socket set (get both standard and Metric). A hammer and rubber mallet. A level, a tape measure. Probably some allen wrenches. Some WD-40 and Duck Tape. That should get you started, you can pick up anything else when you actually need it. Check out estate sales and second hand stores. I've bought tons of great tools for pennies on the dollar. For example I just got an 8 foot aluminum level from a second hand store for $10 recently. The cheapest you can find those for new these days is $50.
  • I've seen people meantion locks. I agree you should change them. That said, Kwikset makes a system called "smart key" where you can rekey your locks anytime yourself easily. I'd highly suggest those. That way if you ever need to change them, you just buy this and change the locks instead of physically having to change every door knob and dead bolt. Go ahead and keep one on hand.

I have two "Highest Priority" items. They seem to be two completely different things- but they are connected. You see, this is to keep my fake-face on.

As a female who wears makeup there is nothing more irritating than when you're doing whatever, you know, looking good.. and suddenly you look at your reflection in a window or something and you're like DAMN WHO LET MY REAL FACE OUT? And you gotta fix that! All that work you spent artfully painting on how your face looks to the public and within hours it's all faded and your eyeliner is halfway down your eyelids. In order to be able to fix it on-the-spot you're suddenly carrying around your whole makeup bag for touch-ups at dinner and when the occasional photographer walks by. Imagine you're out on a date with some hottie and you're like "hey sorry I have to go powder my nose", then you pick up your 3 gallon purse with every brush and gloss known to mankind (all only half-full, of course) and drag it off to the bathroom!

This is just safety standard to cool down after you look so hot for so long. (It can also be used as a blunt weapon to beat the hundreds of people you attract off of you)

my lie? I'm named after a song by either Bob Dylan, Stevie Nicks, or Hall and Oates. You decide which one is the lie ;-)

u/MeishkaD · 2 pointsr/Random_Acts_Of_Amazon

Maybe it's just because I am a mom, but my go-to recommendations are always the things you reach for at 3am and then kick yourself for not having had the foresight to own.

  • An absolute must is a pack of 9 volt batteries. It seems like no matter how frequently you check or swap the batteries in your fire alarms they will sing the song of their people in the middle of the night annually.

  • Basic First Aid Kit, and a well stocked medicine cabinet. You can buy a kit like the one I linked, but I prefer to just pick out each item individually. Think of the things you frequently pulled out of the medicine cabinet when you were still living with your parents and start there.

  • A fire extenguisher is a good thing to have. While you are at it, get one for your car as well.

  • Night Lights so you don't stub your toe in the middle of the night.

    I don't want to type a novel here, so I will stop. Just think of the things you reached for without thinking while growing up. Start with the things you will use most often and those that are needed for real emergencies and go from there. Hope this helps and congratulations!

A fire extinguisher and a first aid kit. The day of moving in to my first place I sliced my finger badly opening a box. Bleeding every where. Couldn't find a thing to wrap it with (cause hey moving) needed 4 stitches. Definitely wish I had a first aid kit then.

Also a base ball bat or a golf club near the door. Lol I just felt safer knowing I had something close by to defend myself with.

Has anyone used an alarm like this one to detect gas? Won't help with the argon, but it would work for propane. I wonder if there is one that would send a text?

u/IAmNotANumber37 · 2 pointsr/Blacksmith

Looks great! Careful with propane in an enclosed space. Perhaps consider getting a CO and flammable gas detector maybe.

u/Johnny_Rockers · 2 pointsr/homeautomation

Could get one of these:

That sensor will trip at 25% of the LEL (lower explosive limit) for methane, which should be plenty of warning.

Since the primary concern with natural gas is explosions, here are some things to keep in mind when placing the sensor:

  1. You want it to be placed as close to the gas source as possible. This is because higher concentrations will be near the source of gas before it gets diluted into the rest of the room.
  2. You want to place the sensor low to the ground. This is because natural gas is heavier than air, so it will tend to collect and travel near the ground.
u/it_rains_a_lot · 2 pointsr/Landlord

It honestly depends where you live, such as a tenants union that you can research and pursue follow up. For example, this is Seattles: . I think it comes down to how much effort you want to deal with this. Do you have natural gas coming in to your place? If not it really may not be worth it. If you're very concerned, you need immediately remedy, and the landlord is dragging their feet, here's one from Amazon from $20

u/Tekpc007 · 2 pointsr/3Dprinting

Very good post ! and you broke some very common sense rules. Smoke detector next to the printer is a must with a fire extinguisher close by! I print overnight and remotely with octoprint , have a wifi cam on my printer and a wifi power outlet so i can shutdown remotely . In the process now of rebuilding my cr10s control box to go into a PC case with a safer PC ATX power supply and better mosfets , better wiring . You really do have to check every single part of a new printer and make sure every screw is tight and inspect all parts about every month , its a must ! this is how you find bad wires, heat damage and faulty loose parts. The quality of these printers coming from china is always suspect , they don't have the same rules about safety and quality of electrical parts , especially these cheap power supplies.

these a good to have next to a printer .

for unattended printing , i have been considering the fire extinguisher ball

> The elevated temperatures of the cast iron is supposed to also allow a more complete combustion of the propane, which further reduces the CO concern.

Unburnt hydrocarbons (which could make the food taste bad) may be a bigger concern than CO. However, it doesn't hurt to be safe, so you can always get a CO detector if it adds to your piece of mind.

> Speaking as an electrician

Thanks very much! That is good to hear coming from a professional. I was proud of my little workaround hack, but I have never read about it anywhere else so I wondered if I was missing something important... but it really does work (I've used it during a couple of outages now). One useful thing to do is to use a little label maker to label the relevant outlets inside the house with "GENERATOR", just to make clear that they aren't usually going to be working. It's also good to make sure that whatever extension cords you get for coming from the generator to the house inlets has a round end for where it's going into the inlet. Some extension cords have the additional tab sticking up which makes it hard or impossible to fit into the inlet socket. Kind of hard to describe, but you'd know exactly what I mean if you see the inlet. Unfortunately the ones I got don't seem to be available any more on Amazon, the product page has gone away, but they looked a lot like these:

And the extension cords for generator to inlet are these:

Notice the female end of the extension cord is round, so it'll fit inside the inlet socket. I think I have the 100 foot and another 50 foot of the 10 ga, for getting from the generator on the rear deck to the two different inlets on the house. The garage one is a bit further away, toward the front of the house, so I need the 100' for that. Usually I'd try not to run so long, but when running the generator in an emergency I'd much prefer for it to be hidden in the rear of the house, not visible to the road. Being 10 ga gives me a bit more room to play with 100' length without losing too much power to the cord.

Other than those, it's a pretty standard job that anybody who's a little bit handy can do - you might also need a 1 7/8" hole saw for the inlet, assuming you have wood walls (we have cedar siding). I used something like 10 or 12 ga house wiring between the wall - I think it might be 10 ga since I remember hemming and hawing on which to use, I believe I went heavier just to be on the safe side. It's a bit intimidating for a non-professional to work with wiring stuff up, but since it's not connected to the actual house wiring, that takes some of the fear out. Just have to make sure you get all the right wires in the right places (not too difficult) and tighten everything up. Also a little bit stressful hacking holes in your exterior house wall, but once it's all sealed up again it's pretty cool knowing you can now get power inside without having to leave the window or door open.

I also have a Kryptonite Stronghold anchor in the back yard next to the deck, for chaining the generators up while they are running, so nobody can just pick them up and run off (a downside of having portable generators is that they are, well, portable):

I dug a hole and then filled it with high stress concrete, then left it to dry for a week or two, then drilled the holes for the bolts and installed the anchor. For chain, I used the strongest stuff I could find at Home Depot. The padlock likewise - just the most beefy, secure one I could find. On the generators themselves, I have installed the security addition to the handle:

This doesn't make it 100% secure, but it's better than just having the plastic handle which is easily broken. Security is a matter of layers - you don't depend on anything being 100%, but you hope that everything will serve to either deter or else slow the thieves down enough so that either they don't try, or else you will be alerted in time to stop them.

Finally, I have a couple of failed circuit alarms, which go off when power is lost:

I figure these could be on the extension bar inside the house while the generator is in use, then if it goes off or is being stolen then I will get an alert when they unplug the extension cord. I am using one of these alarms in the garage now, for the chest freezer so I'll know if that circuit trips out for whatever reason (avoid thawed out freezer, never fun).

Anyway, hope that helps anyone else who might be thinking about a similar setup - the Honda EU2000i is a great little generator (I also have the Companion), and with a little forethought you can make it much easier to use in your house in emergencies. Oh, and one last thing - I also have a large folding plastic table, which can be used to put over the generator if it's raining outside when you need to use it. Obviously the generator can't be too near the house, because of risk of carbon monoxide, so being outside puts the generator at risk of exposure to the elements. One of those folding tables, you can get from any department store, is useful for putting the generator under something. If the rain is especially heavy, I can put an additional tarp over the table, which can also cover two sides, and a couple of cinder blocks makes it ok in the wind.

Incidentally, this is a good battery powered CO detector, great for emergencies if you need to run a Buddy heater inside the house, or make sure the generator exhaust isn't blowing inside:

u/karmaisdharma · 2 pointsr/vandwellers

I usually get the Kidde combo detectors. However, the lithium versions seem to have more complaints than the replaceable battery versions. Have installed those in two houses and knock on wood no issues.

u/anonymous500000 · 2 pointsr/homeassistant

First Alert (very common manufacturer of detectors) has a zwave alarm for $39 on amazon. I think contractor grade alarms are $10, so not a huge least compared to going with Nest.

I lost everything when my house burned down completely, so I'm a bit more paranoid about it than the avg. person. Fire marshal said that it had started hours before it was reported (I lived in area with 1/2 acre lots, so neighbors weren't exactly close, but weren't far either). Now I have the option to call a neighbor and ask them to go check on things if I get an alert.

u/--bohica-- · 2 pointsr/homeautomation

Well, there is of course the Nest Protect, which is wifi-based. No web interface, and requires their app to set up. It can be configured out of the box to email you alerts, and the alert settings are configurable (email vs text vs app notification, and for which alerts/conditions).

There is also the First Alert Smoke/CO Combo, which is Z-Wave based. Again, no web interface. You would rely on your hub for configuring your notifications.

u/Buelldozer · 2 pointsr/HomeImprovement

I gave up on these. I took all of them out and replaced them with combo Smoke / CO2 detectors that are linked to my SmartThings hub as part of my home automation.

u/ComeToVoat2 · 2 pointsr/arduino

I happened to see this while I was browsing around on Tindie the other day. You might be interested.

I like the enthusiasm but honestly it's probably easier and safer to use existing solutions: put one of those extinguisher bombs on top of the printer (eg. ) which should handle the fire and wake the neighborhood at the same time, and make sure your smoke alarms batteries are good.

u/Roboticide · 2 pointsr/3Dprinting

Yeah, I'll probably look into a cutoff as well.

>Something like the AFO Fireball

Holy fuck, this thing?!?

>when it comes into contact with fire and disperses non-toxic chemicals to extinguish the flames in an area with a radius ranging between 86 to 107 square feet.

This exploding in an enclosed structure of approximately 8 cubic feet would definitely put out any fire. It'd probably blow out the enclosure as well, but hey, no fire.

I might see if there's a smaller one. Definitely seems more useful than the stovetop one.

EDIT: Interesting thought though, if you mounted the AFO ball with a 3D printed plastic mount to the top of an enclosure, the heat would probably melt the plastic enough to drop the ball directly onto the fire before the fire got big enough to ignite it normally. Putting it out earlier.

u/redhandfilms · 2 pointsr/ender3

Fire Extinguisher Ball on Amazon.

Here is the one I got. It comes with a little stand that I just zip-tied on top of my printer. It's basically a ball wrapped in a fuse with a fire-cracker and extinguishing powder inside. Flames touch the fuse and the thing explodes (small, safe, youtubers have set them off in their hands) and sprays fire extinguishing powder everywhere.

u/Tre_Walker · 2 pointsr/microgrowery

Lights, fans, cooling, heating all contribute to your amperage pulled and this is the number the breaker uses to determine overload. Running a 5x5 space with 2 QB + COB+smaller lights on my veg space + intake and exhaust fans+ pumps etc and am pulling 800 to 1000 watts at any one time about 8-9 amps on a 15 amp breaker. I also have an AC and dehumidifier unit which pulls 8-10 amps by itself and there fore must go on another circuit. I could not run all that unless I split it up.

My point is don't underestimate TOTAL usage by just assuming lights are the only draw and yes buy a kill-a-watt meter it is very useful if you have any doubts. Also be sure the breaker you think it is is the one that it actually are using by plugging something into it and shutting the breaker off.

It is possible to do what you want on 10 but for me that would be cutting it close depending on peripherals. You can also tap into that 220v? dryer oulet but that is a longer topic.

u/enjoyitalready · 2 pointsr/GoRVing

Interesting! Wonder how well they perform in an enclosed area like an RV or room. A fire extinguisher directs the chemical directly at where the user aims it. This is beneficial that the user won't inhale whatever chemicals are being deployed. The AFO fire ball does a 360 so it hits everything, which has its benefits, but I'm guessing you end up inhaling a lot of this product.

Amazon link to the AFO:

Obviously the lack of fire is the best option in these scenarios, in my non fire professional opinion.

These remind me of the fire ropes too, can't find the link right now though.

Edit found the link to BlazeCut, doesn't appear on Amazon any more for some reason tho:

Glad that you're all right! Yeah, CO is very scary because you won't know what hit you until it's too late. Get at least one for each floor of your house, particularly the basement. This is the model I have in my house. It's pricier than those that are battery only, but after having a few CO alarms scare the shit out of me with their beeping (which was just to indicate that the battery is low), I prefer those that can be plugged in, AND have a numeric counter so I'll know whether it's really CO or just the the backup battery that needs to be replaced.

Get a deep fry thermometer that clamps onto the side of the pan. Don't let the oil get hotter than 375. At that temperature, canola oil will not flash.
Use a pan that has a metal lid. In the unlikely event that an attended pot that never exceeds 375 catches fire, put the lid on to smother the fire.
Make sure your potatoes (or whatever) are dry before you put them into the pot, add them slowly so you can stop if the oil starts to boil over. If the oil does boil over and catch fire, use your handy fire extinguisher

Keep a fire extinguisher in your kitchen. Important note: make sure it's the right type (Type A,B and C fires) This is a basic one on amazon.

Second note: Its VERY important you keep it by the door you're most likely to run through and NOT by the stove. Because your first instinct will be to step towards the door and by the time you think to use an extinguisher it's entirely possible your access to it will be blocked by the fire. So always put it towards the nearest exit. Or one by each exit to be extra safe.

> After setting—and squelching—more than 20 fires, we had a winner. We’d assumed an all-around, ABC- type extinguisher would top our list, given its versatility. But the winner’s virtues were undeniable. It stood out among the traditional models for being especially simple to operate and for its powerful, extremely controlled spray with spot-on aim that was remarkably efficient. It took just seven seconds to put out the grease fire and 21 seconds to completely snuff out the burning dish towel (and it’s not even rated for combustible material). What’s more, in each case I felt I had barely used any of the contents. This model came in neck and neck with an ABC extinguisher, which contains damaging monoammonium phosphate. While the choice between a destroyed home and a scarred stovetop is no choice at all, we felt every bit as safe with our favorite model, with its nondamaging sodium bicarbonate. When the smoke cleared, this extinguisher was our top choice for safety in the kitchen.

u/paperkeyboard · 1 pointr/pcmasterrace

Worse case scenario, your computer can literally catch on fire and it can spread like any other fire. The better the PSU, the lesser the chance for anything catastrophic. However, even super crappy PSUs are unlikely to catch fire. When a high quality PSU fails, most likely the only thing that will happen is the PSU itself stops working. When a low quality PSU fails, it might take some other parts with it, but probably won't catch on fire. So your PSU is very unlikely to actually catch on fire, but it never hurts to be prepared. You can buy a cheap fire extinguisher from amazon for like 15-20 bucks and just keep it near your desk. For example: This traditional extinguisher or something smaller/easier to use Hope this helps.

u/TheyCallMeRINO · 1 pointr/homeautomation

Thanks for all of the comments! Very helpful overall, I really appreciate it. One small point, though:

>Not positive on this point, but I think you must wait for the smoke to clear. I think the design idea is not not be tolerant of false alarms. If the Kidde SD detects smoke/CO, it is not wrong, shit's on fire.

We have a Kidde Nighthawk plugged in outside our master bedroom ... and invariably, whenever we host a party at our house and have 30-40 people over, the thing starts going off ... it's ridiculous. Fortunately, that one is easy enough to rip out of the outlet and pull it's battery out without going into the garage to retrieve a ladder ... so ... I'm naturally a bit cautious on how false alarms could be cancelled. This seems to be a known issue for Kidde - check out the number of false alarm reports on Amazon reviews, although it's on the GAS side (not CO).

It actually even false-alarmed once while we were away, traveling internationally (the Dropcam picked it up as an audio alarm).

u/Jessie_James · 1 pointr/HomeImprovement

I may be mistaken, but I believe you can buy a sensor which detects heat or fire but not smoke. This would likely be ideal for your garage.

Normal household smoke detectors pick up particulate matter which is the by-product of combustion, such as vehicle exhaust. They also will pick up dust, like sawdust, and trigger. You'd likely get a few false alarms if you used one of them.

You can buy a can of ...stuff that makes a vapor cloud to test smoke alarms. Or just find someone who vapes. It's not a good idea to blow real smoke into them because that can gum things up. Vape leaves little residue though.

I also had the same thought as you, but recently I had a batch of smoke alarms where the buzzer part itself was not working reliably. And I detected that using the test button. So it's not completely useless.

Here's a link to the testing stuff, I can't vouch for this brand, it's just an example.

u/rckymtnrfc · 1 pointr/Nest

I'm not sure if the Nest smoke detector uses photoelectric or ionization sensors, but if it's photoelectric, you can buy this to test it.

Edit: Noticed someone said this also worked for a smoke detector that uses ionization sensors, so this should work for your purposes.

Two quick questions:

  • In my home country we were always taught to just get any old kitchen towel, damp it, and then throw it over the fire to smother it. Is this advice incorrect? I can totally understand why you wouldn't want to use a real fire blanket, as they're heavy and hard to position, but this wet kitchen towel thing seems unlikely to knock over the oil as the towel wouldn't have enough weight to move it. Worst case scenario it would catch fire itself.
  • What is your opinion on these: they claim they can handle oil and grease fires?

Get some of these aerosols and keep them in your kitchen. They spray with one finger like hairspray. We keep one in the kitchen and one in the laundry room (we have a gas dryer).

If you want a CO Detector you can get a battery powered one. Main worry would be: you're asleep in a parking lot/festival area (Walmart/rest area), someone pulls up next to you, they fire up their generator (somehow that doesn't wake you up; ear plugs/alcohol), exhaust goes straight in your window, you die. All of this is way low change probability but it has happened and people have died.


Lights - lots of USB lights out there. You can power them and the fan off a powerbank if you want or go to something a little bigger like a GoalZero yeti. If you're getting a DC fridge I'd install an auxiliary/house/leisure battery setup otherwise there are probably less complicated solutions. I've wanted to do a house battery but it has been too involved so far to get done.

Nest is an option, but at $99, it is a bit too steep for my liking.

Something like this will work

u/NickE25U · 1 pointr/homeowners

I found mine while walking through a big chain home improvement store. But mine is basically this: But not the fancy lithium one.

And yes, chaining them all together is the best way to go. But if you can't do it due to wiring restrains or something along those lines, not the end of the world.

u/scottocs · 1 pointr/homeautomation

Actually, it's not false info. The First Alert Z-Wave (keyword, Z-Wave) Smoke and CO2 Detectors do not work with the Wink Hub. It shows as a failed node in the Wink app, and I can't use it.

u/koopa2002 · 1 pointr/homeautomation

Do you have any sort of hub or smart home devices already?

Or just you bought some new alarms and trying to make them work?

Edit: are these the ones you are talking about?
First Alert 2-in-1 Z-Wave Smoke Detector & Carbon Monoxide Alarm

u/brent20 · 1 pointr/homeautomation

Z-wave battery operated ones exist from FirstAlert, but why they don't make a hardwired version is beyond me.

Maybe the Leeo will work for you? Yes it's a detector for your detector.

The Smartthings community seems to talk about it:

u/colonelpan1c · 1 pointr/SmartThings

No worries. I have this First Alert smoke and CO detector. It's been working well, and does report the battery status, accurately in my experience.

u/cat_dev_null · 1 pointr/HomeImprovement

Z-wave smoke/CO2 detector: ($44.96 Free Shipping for Prime Members)

u/BriefcaseCat · 1 pointr/homeautomation

Assuming you are using Z-Wave:

Hard-wired Interconnected, Z-Wave Smoke/CO detectors don't exist to my knowledge. First Alert has one that has wireless interconnections.

You could get creative with some cheap door contacts and utilize the on-board alarm relays of conventional smoke/co detectors.

I think the best return on your money is figuring out what is causing the false alarms.

Some guidelines that deal with common false alarms:

  • Kitchens, Bathrooms, the areas immediately outside kitchen/bathrooms, Furnace/Boiler Rooms - Use Heat and CO detection only.
  • Move any smoke detector that is in path of any air supply vents or returns.
  • Large temperature swings can cause false alarms in most detectors (front of doors leading to the outside or garage).
  • Having detectors in areas that get below freezing or above 100F.
  • If you have an open floor plan, that complicates smoke/air propagation from the kitchen and bathrooms.
u/h_bar · 1 pointr/3Dprinting

I would think something like this automatic extinguisher to actually deal with any fire that might have spread to anything combustible plus some kind of wifi/zwave/etc enabled smoke detector, a home automation hub, and a toggle-able outlet to kill the power and prevent any continuous ignition source.

Personally, I recently got a Smart Things Hub and have been considering something like this smoke alarm with one of the many toggle-able outlets. Smart Things allows you to setup rules and what not so if the alarm goes off, power down the outlet. There might be cheaper/better options but that's what fits in with my home automation equipment.

u/Kv603 · 1 pointr/homesecurity

Have you considered SafeAwake?

Personally, I have First Alert ZCOMBO and a separate Z-wave strobe/siren.

u/pjvaldez · 1 pointr/smarthome

Nest protects Barely Go on Sale. I've seen Protects go for ridiculously cheap at walmart, but thats cuz they were discontinuing the stock on shelf. Aside from that, Protect go $80 to $100 average on Ebay/Offerup/Craigslist. If you aren't a nest Fan Boy, you can go with a $30 First alert Zwave smoke/carbon alarm. I was looking at the insurance Discount, but for Us, Liberty mutual had a higher Monthly rate, didn't justify the swap just for a smoke detector.

u/fps81 · 1 pointr/homeautomation

I have 2 bedrooms and a bathroom at the top of my stairs, so I ended up having to pull the plug on all 3 of those detectors before it shut up, plus the one at the bottom of the stairs, and the one in the living room. I think the smoke wafted past all 5 over the 10 minutes, and they were all pissed off. I have high ceilings and an open balcony between the first and second floor, so smoke travels upstairs quick.

I bought one of the First Alert ZWave detectors, ( but I couldn't get any software to actually interface with it, and the ZWave documentation is sparse. As far as I can tell, it only sends ZWave alerts, it doesn't respond to any commands.

u/massahwahl · 1 pointr/homeautomation

We got ours 4 years ago, I don't remember seeing combined detectors back then but to be honest I don't know that I would have ever looked. I WANTED a smart solution although when looking at the prices for these units now I found a ZWave compatible dual unit for $50... Definitely makes me reconsider what units to get when I convert my other ones...

Edit: For anyone interested here is the Z-Wave one

u/teriyakisoba · 1 pointr/Abode

Looks like it's the same one I bought from Amazon, or at least it mentions the G in the product description. It paired up just fine with Abode.

u/SharkOnGames · 1 pointr/homeowners

I have no idea about heal tolerances, but I found one that wirelessly connects to others, so if one goes off they all go off. I hooked up 3 of these in my house that doesn't have any hardwired smoke detectors.


EDIT: Alternatively, you could get one of these which connects to smartthings hub, so if it goes off you could get notifications on your phone. I actually bought 3 of these as well:

u/RobotFighter · 1 pointr/news

Not so much, this one is $25.

u/chesterjosiah · 1 pointr/AdviceAnimals

I JUST installed three of these--one on each floor of my house. Combination smoke detector + carbon monoxide detector. $32 each on AMZN:

After installation, I pressed the button to test it, and it beeps loud A.F and then a female voice says "smoke detected" or "carbon monoxide detected". Freaking awesome.

u/pixelprophet · 1 pointr/worldnews

If you are buying smoke detectors, look for the smoke / carbon monoxide combos.

Such as this one for $25 on Amazon

u/Maximilian-A · 1 pointr/3Dprinting

Yes its true if wood is around or any flammable material it would be wise to take precautions. However remember that you will never really exceed 275°C when printing and most fires with 3D printers happen due the heater cartridge falling out or when the wrong mosfets are installed on the electronics board. If however you really want to be safe install this fire ball extinguisher on top of your 3D printer:

The downside of this ball is that a false positive alarm will cost you your printer. A thermal camera or a smoke detector connected to the PSU will trigger when the fire already happened. This means you have to extinguish the fire yourself and If you are not close by this might be an issue.

u/sacrilegious · 1 pointr/3Dprinting

Get one of these single-use flame extinguishing balls:

Amazon link

u/engineered16 · 1 pointr/3Dprinting

Smoke alarm, webcam, and fire extinguisher nearby, but most importantly it's in an area where it could burn to the ground and not set the rest of the house on fire.

Ideally the smoke alarm should be tied to a smart outlet that the printer is plugged into, so it can automatically shut down.

You could also set one of these automatic extinguishers over your printer.

EH I have such a nice setup / case, and I know fire chance is low but peace of mind would be nice.

I'd prefer a mini one of these:

u/secretspy711 · 1 pointr/hobbycnc

A simple, cheap enclosure is not difficult to build. I wouldn't let the lack of an enclosure restrict your choice. Carvey and Nomad are good choices, but I'd argue that a Shapeoko3 might be a better value because of its more powerful spindle and motors, and larger work area. The primary drawback of the Shapeoko 3, in my opinion, is the fact that it uses V wheels instead of real linear bearings, which means swarf can collect on the rails and wheels, and cause some problems, and they need to be adjusted properly. If you are interested in a 5-axis machine, there's the PocketNC although it's a bit of a step up in price at about $5,000+, and the work area is smaller, but you can do more complex parts. You didn't say what your budget was, but at that price, you are starting to get into range of a "real" machine such as a Tormach 440, but I'm not sure if that meets your portability requirements. You say you want it to be somewhat portable, which means lightweight, but generally the heavier the machine is, the more performance you'll get out of it. Rigidity is the name of the game in machining. Also consider the fact that after you buy the machine, you will need to spend some money on some endmills, so leave room in the budget for that.


Another thing that you need to understand is that CNC's are inherently more dangerous than 3D printers. It's not advisable to "set it and forget it" like you do with 3D printers that you let run overnight. People's shops/houses have burned down because of their unattended CNC. There are some simple fire suppression systems you can put in the enclosure, but nothing beats a human standing by, ready to hit the emergency stop button.

Also, a CNC does not quite have the same learning curve as a 3D printer to use it successfully, and it also costs more to operate. Most people can get onboard with the fact that they have to pay for 3D printer filament since it's a consumable. But it's a different dynamic when it comes to endmills. Endmills get dull or broken and need to be replaced. They need to be considered consumables too. And you need to have a decent variety of endmills on hand, with some backups. And you should have someone inspect the machine and tools on a regular basis. There is a Shapeoko3 in the employee makerspace here at my work, but every time I've been down there, I give it a little jiggle and it's apparent that the V wheels are not adjusted properly. New users wouldn't know to look for that.

Fire? That's what monitoring and alerting is for ;P

I came across your post while researching fire risks. I think I'm going to make my own post but I came across a couple products to give me some piece of mind at least.

Searching Amazon for "automatic fire" will give you as much information as I posses on the subject. I.e.

u/SirJohannvonRocktown · 1 pointr/3Dprinting

Thanks! I don’t use this one, but I use something similar, but in tube form, that was marketed as an engine bay product. I know there are many products that are pretty much the same. I honestly don’t recommend anyone uses an in home 3D printed without automatic fire suppression. I know of people who have burned their home down because of malfunctions. A $30 preventative measure could save you so much on a non-trivial risk.

I don't get your question? Zwave is Zwave. Is pretty much the most prominent and pervasive home automation communication protocol. So yeah, it's interconnected?

You add this to your network, and then use your hub/controller software to respond etc. If you're not American, then make sure you get the global one.
