What is the appropriate action regarding defective respirator parts?

• A. They must be replaced immediately to ensure proper protection.
• B. They can be repaired and reused.
• C. They should be cleaned and used again.
• D. They should be replaced only during comprehensive maintenance.

Answer: (C)

When a respirator part is defective, the protective function can be compromised because seals, connections, or filtration may no longer perform as designed. The safest course is to replace the defective part immediately to maintain proper protection. Cleaning and reusing a defective component won’t restore its integrity and can hide leaks or fit problems, leaving you exposed. Replacing only during comprehensive maintenance delays protection and isn’t appropriate when a defect is present. After replacing the part, reassemble and perform a proper fit check to ensure the respirator still seals correctly and functions as intended. Only components that are not defective should be cleaned or maintained according to the manufacturer’s instructions.
