Abstract: A powered air purifying respirator (PARR) has a yoke and a pump. The yoke defines an air inlet and an air outlet fluidly connected via an air flow passage. The pump is disposed within an interior of the yoke and is configured to pump air from the air inlet to the air outlet via the air flow passage. The yoke is shaped to fit around the user's neck and be supported by the user's shoulders. A hood for a PARR has a head portion configured to receive a user's head, and a one-way exhaust valve configured to vent air from an internal environment of the hood to an environment external to the hood. The hood is configured to receive a yoke of the PARR.
