I'm not the OP. I never claimed that sawdust in a home woodshop is a fire risk (it's not), just that brushed motors aren't what you make them out to be.

- MarkMarine 4y agoThere is a difference between brushed motors that are open, vs sealed. A sealed brush motor complies with class 2, explosive dust environments. Actually explosive, like grain. But not class 1, where you have explosive gas mixture environments, there you need an explosion proof motor casing that can contain the explosion. If you have a properly size electric motor, with a sealed case, it’s not a problem in a wood dust environment. You’re still responsible for sweeping up the dust, to comply with fire codes for a bunch of other reasons.
