The protective coat that is part of a protective clothing ensemble for structural firefighting, also called a bunker coat, is referred to as a turnout coat.
Turnout coats are designed to provide firefighters with protection against heat and flames. They are made from fire-resistant materials like Nomex, which can withstand high temperatures. These coats feature multiple layers of fabric and insulation to provide thermal protection.
In addition to the turnout coat, firefighters also wear other protective gear such as helmets, gloves, and boots to protect themselves while fighting fires.
