That OSHA manual sure gave me a vintage fuzzy like those old instruction videos from the 60s I come across every once in a full moon but hey… At least it shed some light ( slaps thigh ) on the matter most notably:
Class 4 - eye hazard if direct, reflected or diffusely-reflected beam is viewed; possible skin and fire hazard
compared to the wording of:
Class 3a - eye hazard if collected or focused into eye
Pretty much confirms my suspicion towards the beam.
Diffuse-Reflection - Basically means unless I encapsulate the whole X-Carve in an opaque/450nm shield I will get blasted with Laser radiation no matter what - Not likely to happen.
I guess I’ll be adding the 450nm screen I’ve ordered to the poorly covered sides of the goggles and, for now, call it a day.
