What are the three layers of turnout gear designed for?

Turnout gear, which is essential for firefighters, is composed of three specific layers, each serving critical protective functions. The inner layer typically provides thermal insulation, protecting the firefighter from extreme heat. The middle layer acts as a moisture barrier, preventing water and hazardous liquids from penetrating while allowing sweat and moisture to escape, thus keeping the firefighter dry and comfortable. The outer layer is designed for flame resistance, protecting against direct exposure to fire and hot gases.

Each layer works in conjunction to ensure that firefighters can perform their duties safely while maintaining mobility and comfort. This multi-layered approach is crucial in high-risk environments where exposure to heat, moisture, and hazardous materials is a constant concern. Other choices do not accurately reflect the primary purposes of turnout gear, as they emphasize aspects like comfort and flexibility, which, while important, are secondary to the protective capabilities that are the primary focus of the gear's design.
