IICRC Trauma and Crime Scene Technician (TCST) Practice Exam

Question: 1 / 400

Is the N-95 respirator resistant to oil mists?

Yes, highly resistant

No, it is not resistant

The N-95 respirator is designed primarily to filter out airborne particles, including large droplets and smaller aerosols, but it is not resistant to oil mists. This limitation arises because the materials used in N-95 respirators are not constructed to effectively filter or protect against oil-based particulates. In environments where oil mists are present, other types of respirators, such as those classified as P respirators (which are oil-proof), should be used to ensure proper protection.

Understanding this distinction is crucial for ensuring safety and compliance with health regulations in various environments, particularly those involving hazardous materials that may include oil aerosols. The correct choice emphasizes the limitations of the N-95 respirator regarding oil mists, reinforcing the need for appropriate respiratory protection based on the specific hazards present.
