I enjoyed some awesome advice from this group that led to multiple layers of fire safety:
- NEVER leave your Glowforge while it’s cutting, scoring, engraving.
- Know the material you’re using and it’s tendency to flame up. e.g. cardboard should be watched carefully.
- Have a moist towel ready to drop on small flare ups.
- Have a spray bottle of water to spritz if those flames grow a bit.
- Use a HALON fire extinguisher to put out larger fires. CO2 extinguishers can damage the Glowforge. I have one.
- Someone recommended having the AFO Fire Ball for fires that get out of control. I have one that I can throw from the door into the room if needed.
The Halon extinguisher and AFO Fire Ball add up to about $160, which is rather cheap security.
I haven’t needed anything beyond #1 yet, but I keep all of the steps in mind. I’m less intense in my scrutiny for PG materials and their settings, but not oblivious.
Hope that this helps.
