PAPR stands for:

The term PAPR refers to a Powered Air Purifying Respirator, which is a type of respiratory protection device used to filter harmful particles from the air before they are inhaled. PAPRs utilize a battery-powered fan to draw air through the filters, which enhances airflow and makes breathing easier for the user, especially in environments where air quality is compromised. This feature distinguishes PAPRs from other types of respirators that rely solely on the user's breathing to draw air through the filters.

The design of PAPRs allows them to be effective in various hazardous situations, particularly during hazardous material incidents where the air may contain toxic substances. Understanding the function and importance of PAPRs is crucial for those involved in hazardous materials operations, considering that they provide a higher level of protection compared to non-powered respirators.
