Asbestos Hazard Emergency Response Act (AHERA) Certification Practice Exam

Why should a respirator be kept in a sealed plastic bag?

1. To maintain its cleanliness

2. To prevent damage from exposure to sunlight

3. To ensure it is always ready for use

4. To comply with regulation standards

The correct answer is: To maintain its cleanliness

Keeping a respirator in a sealed plastic bag primarily serves to maintain its cleanliness. Respirators are critical pieces of personal protective equipment, and their effectiveness can be compromised if they become contaminated with dust, dirt, or other particulates. Storing them in a sealed bag helps to prevent these contaminants from accumulating while the respirator is not in use, ensuring that it remains clean and ready for immediate application. While the other choices touch on important aspects, they do not capture the primary purpose of this best practice. For instance, while a sealed bag may provide some protection from sunlight, this is not its primary purpose. In terms of readiness, a respirator should be stored properly but should also be regularly inspected to ensure it functions correctly. Lastly, compliance with regulation standards is important but not the focal reason for sealing a respirator; maintaining its cleanliness is paramount for safe use in environments where airborne contaminants might be present.
