In addition to controlling exposure, which measure helps minimize manganese fume exposure?

• A. Respirators
• B. Hearing protection
• C. Safety glasses
• D. Gloves

Answer: (A)

Manganese fume exposure is primarily a inhalation hazard, so the protective measure that adds real protection beyond engineering controls is wearing a respirator. A respirator filters or purifies the air you breathe, helping to keep fumes from entering the lungs when ventilation isn’t enough or for short tasks. Hearing protection, safety glasses, and gloves protect other parts of the body or senses but don’t reduce inhalation of metal fumes, so they don’t address the main route of exposure here. Use the appropriate respirator with proper filters and fit testing to ensure effective protection.
