How unsafe and what kind of dangers am I going to be under if my brother buys a new laser engraver? The past one, a 3W/450nm, enough to blind, is gone and was given to someone else but he did mention getting a new one after that, I worry that he might have enough money to order it now on january, it could arrive within a range of either 1 to 2 months, so I have to move before that happens, but since I have no job, I cant.

Tell me about
>cancer
>laser reactions with materials Toxic and Lethal, chlorine being one of them
>Eye damage
>fire hazard

He will use it in his room with no proper enclosure and with TEO FUCKING FANS as ventilation HAHAHAHAHHAHAHAHAHAHA, HE'S FUCKING RETARDED.
