What is an R and P disposable respirator?

Respirators play an important role in protecting workers from breathing in harmful substances. Two types of respirators often used in workplaces are the R and P disposable respirators. But what exactly are these respirators and how do they differ from each other?

R and P disposable respirator

An R disposable respirator provides protection against substances that are oil-based and that contain solid or liquid particles, such as certain types of dust, mist, and fumes. Some examples of industries where R respirators may be used are construction, mining, and manufacturing. The “R” in the respirator’s name stands for “resistant,” meaning that the respirator is designed to be resistant to oil.

One popular type of R disposable respirator is the N95 respirator, which is commonly used in healthcare settings. The N95 respirator is an R respirator that filters out at least 95% of airborne particles larger than 0.3 microns in diameter. N95 respirators are recommended by the National Institute for Occupational Safety and Health (NIOSH) for use in healthcare settings during procedures that may generate aerosols, such as intubation or bronchoscopy.

A P disposable respirator, on the other hand, provides protection against substances that are not oil-based and that contain solid or liquid particles, such as certain types of dust, mist, and fumes. Some examples of industries where P respirators may be used are food processing, pharmaceuticals, and agriculture. The “P” in the respirator’s name stands for “oil-proof,” meaning that the respirator is designed to be oil-proof.

One popular type of P disposable respirator is the P100 respirator, which is designed to filter out at least 99.97% of airborne particles larger than 0.3 microns in diameter, including oil-based particles. P100 respirators are recommended by NIOSH for use in industries such as construction, chemical processing, and metalworking.

Both R and P disposable respirators are available in a variety of styles, such as cup-style respirators, flat-fold respirators, and valve respirators. Some respirators also come with additional features, such as adjustable straps, foam nose cushions, and exhalation valves, to make them more comfortable and effective to wear.

It’s important to remember that disposable respirators are designed for single-use only and should be discarded after use. If a respirator becomes damaged, soiled, or difficult to breathe through, it should also be discarded and replaced.

R and P disposable respirators are both important tools for protecting workers from breathing in harmful substances. An R respirator provides protection against substances that are oil-based, while a P respirator provides protection against substances that are not oil-based. Both types of respirators are available in a variety of styles and are recommended by NIOSH for use in specific industries. By wearing the appropriate respirator for their work, workers can help protect themselves from respiratory illnesses and other health hazards.
