Firefighters are required to use a self-contained breathing apparatus (SCBA) for respiratory protection when engaged in a variety of firefighting duties. While the SCBA provides crucial respiratory support and protection, it is also cumbersome and he

Firefighting is an injury prone occupation. The self-contained breathing apparatus (SCBA) included as part of a firefighter ensemble contributes to these injuries by affecting a firefighter’s balance. The objective of this study was to establish a

Twelve subjects wore an N95 filtering facepiece respirator (N95 FFR), one tight-fitting full facepiece powered air-purifying respirator (PAPR), two loose-fitting PAPRs, and one elastomeric/PAPR hybrid for 1 hr each during treadmill walking at 5.6 km/
