A filtering facepiece respirator classified as P100 must be able to filter at least 99.97% of airborne particles. This high level of filtration is essential for protecting workers from hazardous environments where exposure to airborne pathogens, dust, and other particulate matter is a concern. The "P" in P100 signifies that the respirator is resistant to oil, and the "100" indicates its filtration efficiency.

Understanding the classification system is crucial for pest control technicians, as choosing the correct respirator can significantly impact safety during the application of pesticides or when interacting with contaminants. For example, respirators with lower filtering efficiencies, like those denoted as N95 or N90, do not meet the stringent requirements necessary for environments with high levels of hazardous particulates. Similarly, the requirement does not pertain to filtration of chemicals, which involves different considerations for respirator selection. Hence, achieving the P100 standard ensures maximum respiratory protection in potentially harmful conditions.
