Class G – General helmet: Designed to reduce exposure to low voltage conductors, proof tested at 2200V Safety helmet classes: To improve comprehension and usefulness, the following designations refer to impact and penetration protection:

Safety helmet classes: To improve comprehension and usefulness, there are electrical-protective classifications for helmets as follows: OSHA requires selection criteria for head protection that comply with ANSI/ISEA Z89.1. Simply put – a helmet that meets ANSI Z89.1 is OSHA compliant. 2. ANSI/ISEA Z89.1 standard – U.S. ANSI helps employers follow OSHA regulations. The performance criteria for head protection is provided in ANSI Z89.1 American National Standard for Industrial Head Protection, incorporated in OSHA’s 29 CFR 1910.135 and by reference in 29 CFR 1910.6. ANSI Z89.1 requires four performance tests that must be met to assign a safety helmet type and class, which are:Like OSHA, the agency’s regulatory authority is derived from a specific law, which the agency enforces. MSHA carries out provisions of the Federal Mine Safety and Health Act of 1977 and administers the Mine Improvement and Emergency Response Act of 2006, which further expanded mine requirements and sanctions. Type 1: Crown-only headwear – Designed for applications where it can be shown that there is no hazard related to lateral impact; reversible headwear should be selected if required

CFR 1926.100: Refers to head protection requirements for construction, demolition, and renovation workers Additional specifications are provided for ear muff attachment points and chin strap attachment points.

Two years later, in 1954, the first hard hat standard, known as The Light Duty Safety Helmet Standard, was introduced as a British Standard. These standards set guidelines for helmets’ design, construction, and performance, ensuring their effectiveness in protecting individuals from head injuries. EN397: The European standard code of practice (EN 397) guides manufacturers of safety helmets to ensure that minimum material grades are used. It also establishes the requirements for testing safety helmets, as safety helmets must be designed to protect the wearer from falling objects. Such protections safeguard the user against possible consequences such as brain injuries or skull fractures. The standard also includes protection against lateral deformation of the helmet. Plastic parts can be cleaned with water and commercially available cleaning products. The helmet can be disinfected using commercially available disinfectants. Do not clean the helmet using non-approved solvents. The Mine Safety and Health Administration(MSHA) is an agency under the Department of Labor that works to prevent illness, injury, and death by promoting safe work practices for U.S. miners.
