Structural firefighting protective coats consist of ___ layers.

Structural firefighting protective coats are designed to provide firefighters with the necessary protection while performing their duties, particularly in hazardous environments like structural fires. The correct number of layers in these coats is three. This multi-layer construction typically includes an outer shell that resists flame and abrasion, a moisture barrier that protects against steam and water, and an insulating layer that helps keep the firefighter warm.

Each of these layers serves a specific purpose to ensure safety and functionality during firefighting operations. The outer layer provides durability against heat and flames, the moisture barrier protects against the elements and prevents water from penetrating the coat, and the insulating layer helps to retain body heat in cold conditions or when firefighters are exposed to the wind.

The three-layer design strikes a balance between protection, mobility, and comfort, making it effective for a wide range of firefighting scenarios. This well-established construction standard reflects current best practices in firefighter protective equipment, emphasizing the importance of layered protection.
