Which statement about removing respirator filters is true?

• A. Never wash the respirator after removing filters.
• B. Only rinse with water.
• C. Wash it with a wet rag and wipe down contaminated surfaces before storing.
• D. Disassemble and store.

Answer: (C)

Cleaning a respirator after removing the filters is essential to remove contaminants and prevent their spread during storage. The best statement is that you wash it with a wet rag and wipe down contaminated surfaces before storing. This approach directly removes dirt, oils, and hazardous residues from both exterior and accessible interior areas, reducing the risk of transferring contaminants to storage spaces or to the next user, and it helps ensure the gear is clean and dry before putting it away.

Other options fall short because skipping washing leaves residues behind; rinsing with water alone may not remove oils or stubborn soils; and disassembling the unit and storing it without cleaning can leave contamination inside parts and complicate proper reassembly later. Always follow the manufacturer’s cleaning guidance, use mild soap and water, avoid harsh solvents, and allow all parts to dry completely before storage.
