A respirator should be worn when?

• A. Cutting lumber
• B. Working in the finish room
• C. Wearing safety gloves
• D. Cleaning dust from bench

Answer: (B)

Wearing a respirator is essential whenever you’re working with finishes or solvents that release harmful vapors. In the finish room, products like varnishes, stains, and polyurethane emit volatile organic compounds (VOCs) and other fumes that can irritate your lungs and eyes or pose longer-term health risks. A respirator with the right cartridges (typically organic vapor cartridges, sometimes combined with a particulate filter if sanding is involved) helps filter those vapors before you inhale them, keeping breathing passages clearer and safer.

This keeps you protected specifically during finishing tasks, where exposure to solvent vapors is greatest. Cutting lumber or cleaning dust from a bench mainly involves dust and particulates; those situations may be managed with local exhaust, dust collection, and, if needed, a basic dust mask, but they don’t typically require the same level of protection as solvent vapors in the finish room. Wearing gloves is about hand protection, not inhalation, so it doesn’t address respiratory hazards.
