[General] Laser Cutter Class Announcement: 1/31/12 @ 7:00pm

[David Reimer]

Hey everyone. I just wanted to toss this out there in hopes that members
become aware of other safety concerns with the laser cutter. A few people
have been cutting plexiglass on the laser cutter, and when that happens, it
vents out into the rest of the shop. Not only does it just smell bad, but
the odor is actually toxic and harmful to breathe in. I'm aware that the
cutter is set up to vent out of that area, but when dealing with toxic
fumes, you can never be too safe, so I'd just like to encourage members who
regularly work with plexiglass on the cutter to pick up an
appropriately-rated respirator (not a dust mask, a *respirator*).
2StoryProps uses respirators when we work with our fiberglass and bondo. So
I'd just like to encourage everyone to be safety-minded when burning
plastic-based materials on the laser cutter.
