According to studies, what is the average core temperature for firefighters in full PPE after 20 minutes of operation?

The average core temperature for firefighters in full personal protective equipment (PPE) after 20 minutes of operation is typically around 101.5°F (39°C). This elevated temperature is a result of the intense physical exertion required during firefighting activities, combined with the insulating properties of the protective gear, which restricts heat dissipation from the body. Firefighters operate in high-stress environments that demand significant physical effort, causing their bodies to generate heat.

It's important for firefighters and their supporting safety personnel to monitor core temperatures, as excessive heat can lead to heat-related illnesses. Maintaining awareness of average core temperatures in training and actual emergency situations can help to inform necessary preventative measures, hydration strategies, and interventions to ensure the safety and health of personnel on the scene.
