How many layers are typically found in structural firefighting protective coats?

Protective coats used in structural firefighting typically consist of three layers, which are meticulously designed to provide firefighters with essential protection against the hazards they face.

The outer layer, often made of durable and heat-resistant material, serves multiple purposes: it is designed to resist abrasion, cuts, and other external impacts, as well as to provide water resistance. The middle layer, usually constructed from a thermal barrier material, is crucial for insulation, helping to protect firefighters from extreme heat. The inner layer is composed of a moisture barrier that helps wick away sweat while also providing an additional level of protection against water and other contaminants.

This three-layer configuration is standardized to ensure that firefighters have an optimal balance of mobility, comfort, and protection, allowing them to effectively perform their duties while minimizing their risk of injury. Understanding the composition of protective gear is vital for ensuring that firefighters are properly equipped to face the dangerous environments they are often called to operate in.
