Which layer of turnout gear is constructed from sturdy, flame-resistant material?

The outer layer of turnout gear is specifically designed to provide maximum protection against flames and other hazardous conditions encountered during firefighting. This layer is constructed from sturdy, flame-resistant materials such as Nomex or Kevlar, which are engineered to withstand high temperatures and repel heat.

The outer layer serves as the first line of defense against thermal and external hazards, ensuring that the structural integrity of the gear is maintained under extreme conditions. It also acts as a barrier against water and other potentially harmful elements while being durable enough to resist tearing and abrasions.

In contrast, the second and third layers of turnout gear typically focus on thermal insulation and moisture barrier functions, while the base layer is designed for comfort and moisture management against the skin. The distinct functions of these layers highlight the critical role that the outer layer plays in protecting firefighters from immediate fire threats.
