Heat-resisting front-brim hard hats (Type 1, Class G) are used in high-heat applications such as metalworking, forging, welding, and smelting. They are classified as ANSI Type 1, which indicates head protection for impacts on the top of the head, and they are Class G to provide low-voltage protection up to 2.2KV. These hard hats are constructed of heat-resistant material that resists damage when exposed to high temperatures. The front brim reduces glare and shades the eyes from overhead sun.
