SafetyCâu 87 / 100
When using a solvent-based coating in an enclosed room, what is the primary way to control flammable vapor and inhalation hazards?
a.Provide adequate ventilation and remove ignition sources, using respiratory protection as needed
b.Light a candle to test the air
c.Seal all openings to trap the vapors
d.Increase the room temperature to speed evaporation
Giải thích
Solvent vapors are both toxic and flammable, so enclosed spaces require adequate ventilation to keep concentrations low and all ignition sources removed. Respiratory protection is used when ventilation alone is insufficient. Cal/OSHA and fire codes address both the health and explosion hazards of solvents.
