Under whose authorization can air-purifying respirators be used?

Air-purifying respirators are designed to protect individuals from airborne contaminants by filtering out harmful substances from the air. Their use is crucial in hazardous environments, and the authority to utilize such equipment is typically granted to ensure proper oversight and safety protocols are followed.

The correct answer is that air-purifying respirators can be used under the authorization of the Incident Commander. The Incident Commander has the overall responsibility for the incident scene and decision-making authority regarding the safety of all personnel involved. This includes determining the appropriate level of personal protective equipment needed based on the specific hazards present.

While the other roles, such as the Fire Chief, senior firefighters, and Safety Officer, hold important responsibilities, they may not directly authorize the use of air-purifying respirators at the scene of an incident. The Incident Commander is specifically trained to assess risks and make informed decisions based on the evolving conditions at an incident, making them the appropriate authority for such decisions.
