Oregon Pesticide Practice Test

When should you perform a qualitative fit test of your respirator?

1. Every month

2. Annually or if you have a significant change in weight

3. Only when a new respirator is purchased

4. Twice a year

The correct answer is: Annually or if you have a significant change in weight

The recommended practice for performing a qualitative fit test of your respirator is to conduct it annually or whenever there is a significant change in weight. This is important because a proper fit is crucial for respirators to perform effectively in protecting against hazardous airborne substances. As individuals lose or gain a significant amount of weight, the configuration of their face may change, which can affect how well the respirator seals. An improper fit can lead to leaks and allow contaminants to enter the breathing zone. Therefore, conducting a fit test annually ensures that the respirator continues to provide the necessary protection, while performing one after a significant weight change ensures that any physical changes that could impact fit are accounted for. This approach aligns with both safety regulations and best practices in occupational health standards, ensuring that users are adequately protected against respiratory hazards.
