Which of the following components is NOT part of protective coats?

The fire retardant collar is not considered a standard component of protective coats used by firefighters. Protective coats typically consist of several key layers designed to provide thermal protection, moisture management, and overall safety.

The outer shell is the first line of defense, made from durable, flame-resistant materials that protect against heat and potential flames. The moisture barrier is vital for preventing water and other liquids from penetrating the coat, ensuring that the firefighter remains dry and comfortable while working in challenging conditions. The thermal barrier adds insulation to protect against heat, ensuring that the firefighter's body temperature remains stable in extreme environments.

While the fire retardant collar may enhance the coat's effectiveness by providing additional protection around the neck area, it is not a standard component like the outer shell, moisture barrier, or thermal barrier, which are essential layers for overall protection in firefighting gear.
