Which class of hard hat is the most common?

The most common class of hard hat is Class G, or General Hard Hats. This type offers protection against electrical hazards up to 2,200 volts, making it suitable for a variety of work environments where electrical exposure might occur. Class G hard hats are designed for general use and provide adequate protection for workers in numerous industries, including construction and manufacturing.

Class E hard hats provide a higher level of electrical protection, rated for exposure to higher voltages, which makes them specifically useful in electrical settings. However, they are not as prevalent in general workplaces as Class G hats. Class C hard hats are intended for lightweight impact protection but do not offer any electrical protection, making them less versatile. Class D hard hats are the least common and are specifically designed for use in mining environments, limiting their application in other fields.

Thus, Class G hard hats are the most widely used due to their balance of protection against electrical hazards and general impact, serving a broad array of occupations.
