3 Effective Ways to Prevent Firefighter Heat Stress

Effects of High-Heat on Firefighter Personnel

Firefighting is a stressful occupation that causes personnel to work in high-heat conditions. This carries a high-heat burden on the body overtime. It's clear that firefighters regularly exert themselves in dangerous and unpredictable environments. Merely getting ready to respond to a fire starts a flow of endorphins and begins putting stress on the cardiovascular system. Combine that with the additional weight of traditional personal protective equipment (PPE) such as turnout gear, it doesn't come as a surprise that the leading cause of line-of-duty deaths and injuries is sudden cardiac failure.

Research from the American Heart Association shows that exposure to extreme heat and physical exertion during firefighting may trigger the formation of blood clots and impair blood vessel function, two predecessors for heart attacks.
