It’s actually an OSHA violation if the employers don’t make the workers aware of all that. All hazards have to be clearly communicated to the workers. If they don’t know the safety issues and necessary safety equipment, the employer fucked up. There’s practically no way for the worker to ever be at fault here unless they are willfully disobeying the employer to do something they know is unsafe.
Even then you could argue the employer should’ve known better than to hire them lmao
