Pest Control Technician Practice Exam

P100 respirators are designed to provide a high level of protection against airborne particles, with a filtering efficiency of at least 99.97% of airborne particles. This specification means that they are able to effectively filter out almost all particulate matter, including very small particles that may be hazardous to health, such as dust, aerosols, and biological agents.

The "P" classification indicates that they are resistant to oil, and the "100" designates the high efficiency of filtration. This level of protection makes P100 respirators suitable for environments where a high degree of exposure to contaminants exists, ensuring that users are well-protected from a wide range of airborne pollutants.

Other options pertain to different standards of filtration efficiency. For example, a respirator noted for a 95% efficiency would be less protective compared to the P100, and those indicating percentages for specific types of particles (like oil) do not match the comprehensive protection offered by P100's specifications. Thus, the defining feature of P100 respirators is their ability to filter out at least 99.97% of airborne particles, marking their superior efficiency in respiratory protection.
