What is the first factor to consider when determining the use of personal protective equipment?

When determining the use of personal protective equipment (PPE), the first factor to consider is the hazard present on the scene. Understanding the specific hazards allows responders to select the appropriate type and level of PPE needed to protect themselves from potential health risks and injuries. Hazards may include chemical exposure, biological agents, physical dangers, or environmental conditions, and recognizing these threats is crucial for ensuring safety and effectiveness in any emergency response.

The other factors, while important, follow after identifying the hazard. On-scene rehab policies provide guidelines for managing responders’ health after harsh conditions, the risk of cardiac arrest relates to the physical strain on responders during incidents, and doffing procedures focus on safely removing PPE to avoid contamination. However, none of these considerations can take precedence over the identification and assessment of the hazards present, as this determines the level of protection necessary to keep responders safe during their operations.
