What is the primary function of personal protective equipment in firefighting?

The primary function of personal protective equipment (PPE) in firefighting is to protect against thermal hazards. Firefighters face extreme temperatures and exposure to flames, which can cause serious injuries or fatalities without proper protection. The gear is specifically designed to provide insulation from heat and prevent burns, ensuring that firefighters can operate effectively in dangerous environments. This protective capability extends to shielding against other physical hazards encountered during a fire, such as falling debris and hot embers, further enhancing the firefighter's safety on the scene.

While PPE may contribute to mobility, breathing assistance, and visibility, these aspects are secondary to its core purpose of thermal protection. By prioritizing protection against thermal hazards, PPE allows firefighters not only to survive in life-threatening situations but also to perform their duties effectively, knowing they are safeguarded against the heat and flames they confront.
