What are the three layers of the protective bunker coat?

The three layers of the protective bunker coat are indeed the outer shell, moisture barrier, and thermal barrier.

The outer shell serves as the first line of defense against external hazards such as flames, sharp objects, and various environmental conditions. It is designed to resist abrasion and provide protection from heat and flame exposure.

The moisture barrier is crucial for firefighter safety as it prevents water and other liquids from penetrating the coat while still allowing moisture from sweat to escape. This barrier helps maintain comfort and prevents the accumulation of moisture against the skin, which could lead to heat stress or hypothermia in extreme conditions.

The thermal barrier provides insulation, protecting the firefighter from extreme temperatures that may be encountered during firefighting operations. It helps reduce the risk of heat stress by providing an additional layer of protection against heat transfer.

These three components work together to ensure that firefighters have the necessary protection to perform their duties safely in hazardous environments.
