Asbestos Contractor/Supervisor Practice Exam

What action should be taken if a respirator is found to be defective during a fit test?

1. Continue the test with a different person

2. Replace it and retest

3. Inform management and proceed without it

4. Document it and use the next available unit

The correct answer is: Replace it and retest

When a respirator is found to be defective during a fit test, replacing it and conducting a retest is crucial for maintaining safety standards. A defective respirator can compromise protection against hazardous airborne substances, which is particularly critical in environments where asbestos is present. Ensuring that the respirator fits properly and functions correctly is a key component of employee protection. Conducting a retest with a new or repaired respirator guarantees that the individual is adequately protected, as the effectiveness of respiratory protection is dependent on both the proper fit and the condition of the respirator. This action also aligns with regulatory guidelines and industry best practices, which emphasize the importance of using equipment that is confirmed to be functional and effective. Proceeding with other options, such as continuing with a different person, informing management without taking immediate action, or simply documenting the defect, do not address the immediate need to ensure a valid and effective fit for respiratory protection. Immediate replacement and retesting ensure compliance with safety protocols and uphold the health and safety of workers.
