Definition - What does Powered Air-Purifying Respirator (PAPR) mean?

A powered air-purifying respirator (PAPR) consists of a battery/motorized unit displacing the toxic elements from an airflow stream through a hose via a filter mesh that feeds a clean air supply into a half/full facepiece. A PAPR respirator is a good option with neutral facepiece sizes conforming to the face. For instance, a tight-fitting and a loose hood facepiece are two examples.

An assigned protection factor (APF) is a tool harvested from raw data that supports the need to choose powered air-purifying respirators primed to disperse airborne hazards between uses in the workplace. The Permissible Exposure Level (PEL) is a backdrop to gauge the APF index, often based on the nature of the job. Healthcare workers, for example, are more likely to use PAPR models with a high positive pressure system that corresponds with a full-face/hooded facepiece option. This approach helps better protect them from biohazards that thrive in restricted areas for an extended time.

Employees must know how to wear, adjust, position, and use PAPR equipment. A party must take a medical test to ensure they can withstand the inrush of air by the powered air-purifying respirator to control their breaths. Guidelines will vary by the manufacturer on how to clean, maintain, and repair PAPR device units.
