Fire retardant headwear is designed to protect the wearer's head and face from heat and flames. It is commonly used in industries where there is a risk of fire or heat exposure, such as welding, foundries, and firefighting. Fire retardant headwear can be made from various materials, including cotton, wool, and synthetic fibers, that are treated with fire-resistant chemicals or coatings to reduce the risk of ignition and to minimize the spread of flames. Common types of fire retardant headwear include hoods, helmets, and balaclavas, which provide full head and face protection and are available in a range of styles and sizes to suit different applications.
