Reddit reviews 10lb ABC Dry Chemical Class A:B:C Fire Extinguisher

If it's a Kidde, and not affected by the recall, I would still consider throwing it out. I'm a firefighter and honestly, I'd rather have nothing in my house than to have a Kidde. Same with their smoke detectors. I see more false alarms with Kidde detectors than I do with any other brand. I once had bi-monthly false alarms regularly in my own house with my Kidde detectors. I ripped them out and bought nest, I ripped out my Kidde extinguishers and bought Amerex. 10lb ABC Dry Chemical Class A:B:C Fire Extinguisher https://www.amazon.com/dp/B00CMUMRP2/ref=cm_sw_r_cp_apa_i_UQRlDbT83JZ2T

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.

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.
