They are a little pricey but compared to the machine and house it is peanuts. They usually last about six years and you can get them recharged for about $30. I have both an ABC and a BC or CO2 in my shop. A little fire can become a big one very quickly. I was working in a shop by myself years ago and a fire started, I grabbed the closest extinguisher and nothing, it was empty and so was the second one. Fortunately the third one worked and by then the fire department was there because I hit the alarm after the first one. It was very scary and after that the owner made it a point to check his extinguishers every month. Most fire departments will check them for free if you ask.

Exclamation Another vivid reminder why we need fire extinguishers

Ran across this video today. Looks like the operator walked away!

I don't leave my machine for much longer than the boys room. I have a smoke alarm above the machine which is wired to all the others. When a bit is spinning in wood and if something goes awry than it doesn't take long to burn
and possibly start a fire. My BC extinguisher is within a few feet. Better safe than sorry. Murphy says that if you are prepared you will not have a problem.

I had a grease fire in my BBQ grill a few years back and used an ABC extinguisher and I had to take it apart and pressure wash it. After I got back together I opened the door on the cart and darn if some powder didn't fall out. I wish I would have had a BC type at that time but at least I had something or my back porch and maybe my house would have burned. I have had several fire experiences and they are no fun at all, very scary.

Early fires were started with friction and a bit spinning at 9 - 18000 rpm is a lot of friction if it get hung up somehow.

3 fires in 11 years. Water for a wood, mdf, fire has always worked fine. Last one was a simple mistake. Wrong bit in a tool holder and the atc picked up a small tool to do a big cut. Bogged down and wincnc errored out. It stopped in the wood with the spindle still running. I never stray far from the running machine and I have a video link in the office, to keep an eye on it running.

Thumbs up

Ken, great idea on the video link. As you know the problem is when it errors and stops moving the spindle just sits there turning and getting hot. I would think there would be away to stop the spindle if there is an error.
