OSHA 30 Hour Construction Program Practice Test

Which of the following is NOT a warning sign to look for when inspecting a respirator?

1. Cracks or chips

2. Dirty valves

3. Shiny outer layer

4. Worn or frayed straps

The correct answer is: Shiny outer layer

The option that indicates a shiny outer layer is not considered a warning sign when inspecting a respirator. Typically, a shiny appearance may not suggest any immediate concern, as it could simply be a characteristic of the material used in the respirator’s construction. In contrast, warning signs such as cracks or chips, dirty valves, and worn or frayed straps indicate that the respirator may not function as intended. Cracks or chips can compromise the unit's integrity, leading to air leaks, while dirty valves can obstruct airflow and reduce filter efficiency. Additionally, worn or frayed straps could affect the proper fit of the respirator, which is crucial for its effectiveness. Recognizing and addressing these warning signs is essential for ensuring that the respirator provides adequate protection to the wearer.
