 TheLab makerspace tries to keep a set of laser safe safety glasses available for use. If you cannot locate them please post a note to the “laser-general” discord channel or purchase a set for your personal use.

+**NOTE: There are glasses currently available in TheLab. A couple sets that are certified for the OmTech and other certain diode lasers. Another set that is certified for the CO2 Trogdor and Glowforge lasers. It's not clear at this time the Xtool D1 machine requirement.**

 For the Trogdor, Glowforge and Xtool D1 machines, the laser light should be contained by their respective enclosures. The laser “should not” fire if the access doors are open. It is imperative that one does not defeat/bypass the door interlocks such that the laser will fire with the door open. This is dangerous for the operator as well as anyone else who may traverse the immediate area.

 There is a fire extinguisher located next to the large red Trogdor machine.
+* If a fire has started immediately turn off the laser main power switch. This should allow the fire to extinguish, if not you will need to resort to using the fire extinguisher. It’s a CO2 extinguisher so should not damage the machine.
+* Immediately notify TheLab discord channels and put a note on the machine to not use until it gets checked over for damage.
