Asbestos Hazard Emergency Response Act (AHERA) Certification Practice Exam

What must be done with facial hair before a fit test?

1. Trim it

2. Shave it

3. Leaving it untouched

4. Style it appropriately

The correct answer is: Shave it

Before a fit test, it is essential for individuals to shave any facial hair that may prevent a proper seal between the respirator and the face. This is because facial hair can create gaps that compromise the effectiveness of the respirator, allowing contaminants to enter the breathing zone. Having a clean-shaven face ensures that the respirator can provide the intended level of protection by forming a tight seal. The fit test is critical for determining whether the respirator fits the wearer properly, and any obstruction caused by facial hair can lead to inaccurate results and increased risk of inhalation of hazardous substances, including asbestos. The need to shave rather than merely trim hair is significant, as trimming may still leave enough stubble to disrupt the fit. Therefore, to ensure optimal protection and compliance with safety standards mandated by the Asbestos Hazard Emergency Response Act (AHERA), complete shaving of facial hair is required before conducting a fit test.
