What is the number of layers in the protective system of turnout coats and trousers?

The protective system of turnout coats and trousers is designed to offer firefighters optimal protection against various hazards, including heat, flame, and certain hazardous materials. The correct answer indicates that there are three distinct layers in this protective system.

The outer layer is typically made of a durable, flame-resistant material that protects against heat and physical damage. The middle layer serves as the thermal barrier, which helps to insulate the firefighter from high temperatures and prevent heat transfer to the body. The inner layer is often moisture-wicking and designed to provide comfort, while also protecting against potential chemical exposure.

Each layer plays a vital role in ensuring safety and functionality, and the combination of these three layers ensures that firefighters can operate effectively in high-risk environments while remaining protected. Understanding this multi-layer approach is crucial for appreciating the safety features embedded in turnout gear and ensuring it meets the necessary safety standards for firefighting operations.
