What respirators shall be used for mixing paint and general painting operations?

• A. Supplied-air respirator
• B. Self-contained breathing apparatus
• C. Chemical Cartridge
• D. N95 respirator

Answer: (C)

Protection from solvent vapors during painting requires a respirator that filters organic vapors. A chemical cartridge respirator uses replaceable cartridges designed to adsorb organic solvents found in paints, providing protection for mixing and general painting tasks when ventilation is adequate. This type targets the vapors, not just particulates, making it the appropriate choice for handling solvents safely during paint work. The other options don’t fit as well: N95s filter particles only and don’t protect against vapors; supplied-air and SCBA systems are used in higher-hazard or oxygen-deficient conditions or when ventilation is poor, which isn’t necessary for routine painting in well-ventilated areas.
