What is a fire shelter used for in wildland firefighting?

A fire shelter serves as a last-resort protective measure for firefighters when they are caught in extreme fire conditions. It is designed to provide a means of survival by reflecting heat and protecting individuals from flames, radiant heat, and smoke. The shelter creates a safe microenvironment, allowing firefighters to endure the intense conditions of a wildfire until they can safely escape.

This use is pertinent because fire conditions can change rapidly, and firefighters may find themselves in situations where there is no safe escape route. The shelter is not intended for prolonged use but rather as a critical option when all other safety measures have been exhausted. Understanding this function emphasizes the importance of fire shelters in a firefighter’s safety strategy, distinguishing their role apart from more permanent solutions or tools used for active firefighting.
