Step-by-step explanation:
The protective head covering worn by firefighters to safeguard against falling objects, blunt trauma, and heat is known as a helmet. It is an essential part of a firefighter's personal protective equipment (PPE) and is designed to protect the head and face from potential injuries and burns.
Firefighter helmets are usually made of durable materials such as thermoplastic, fiberglass, or carbon fiber. They are equipped with a face shield or visor to protect the firefighter's eyes from smoke, debris, and heat. The helmet also provides insulation against high temperatures and radiant heat.
In addition to helmets, firefighters also wear other protective gear such as fire-resistant hoods, gloves, turnout gear, and self-contained breathing apparatus (SCBA) to ensure their safety in firefighting situations.
