Job site I'm werkin on the painter is spraying lacquer on the custom wood work in the office.Well the stuff is in the air throughout the job.The concentration of the lacquer in the room he is working in is high enough that he wears a respirator.

I won't work in the place while the overspray is flying around.Is my concern warranted?Is prolonged inhaling of this harmful to others working in the place without respirators?
