So, catch-22? An MSDS purpose isnt to prove that something isn’t hazardous (though it’s used that way by most of us). And an MSDS doesn’t have to be created for non-hazardous materials.
I don’t care to chase the rabbit down the hole, but there are a few applicable areas as far as wood that could apply.
29 CFR 1910.1200(b)(6)(iv) could apply
It could also fall under the Consumer Product Safety Act requirements rather than HCS, I believe.
One of the things that may make a difference here is that Glowforge does not have or offer commercial accounts, which can change requirements.
Anyways, that’s for GF lawyers to figure out.
