Which type of respirator is not resistant to oil?

N-rated respirators are designed specifically for non-oil environments, meaning they do not provide any resistance to oil-based aerosols. These types of respirators are suitable for situations involving non-oil particulates, but they should not be used in environments where oil aerosols are present, as they would not offer adequate protection.

In contrast, R-rated respirators can provide some resistance to oil, although they are not suitable for prolonged exposure. P-rated respirators, on the other hand, are designed to be resistant to oil and can be used in environments with oil aerosols for an extended period. Understanding the classifications of respirators and their specific capabilities is crucial for ensuring safety and compliance in various working conditions related to trauma and crime scene remediation tasks.
