Get to know the U.S., European, and Canadian standards for safety helmets Unsure what kind of safety helmet you need? What hard hats comply with what standard? Where to start? We want to make sure staying compliant is second nature, especially when it comes to keeping your head safe. There’s a lot to know and a lot to pay attention to when it comes to safety helmets, but don’t worry – we’ve done the research for you. In this blog, we’ll dig into OSHA, ANSI, EN, and CSA standards. OSHA standard – U.S. The Occupational Safety and Health Administration (OSHA) mandates specific requirements for head protection in the workplace and instructs that, regardless of industry, it’s the employer’s job to ensure their workers wear head protection when exposed to risks/hazards. To help employers follow those regulations, OSHA incorporates standards from the American National Standards Institute (ANSI), which is discussed in the next section. Here’s what you need to know about OSHA’s head protection regulations. Safety helmet standards : OSHA has two standards that regulate safety helmet requirements: 29 CFR 1910.135: Governs safety helmet requirements for general industry workers 29 CFR 1926.100: Refers to head protection requirements for construction, demolition, and renovation workers Safety helmet requirements : Both standards require workers to wear safety helmets if they are at risk of being struck by falling objects, bumping their heads on fixed objects, or coming in contact with electrical hazards. OSHA requires selection criteria for head protection that must comply with ANSI/ISEA Z89.1. Simply put – a helmet that meets ANSI Z89.1 is OSHA compliant. ANSI/ISEA Z89.1 standard – U.S. ANSI helps employers follow OSHA regulations. The performance criteria for head protection are 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 in order to assign a safety helmet type and class, which are: Force Transmission Apex Penetration Flammability Electrical Insulation Safety helmet types : There are two types of protective safety helmets under this classification system that refer to impact/penetration protection: Type 1: Designed to reduce the force of impact resulting from a blow to the top of the head Type 2: Designed to reduce the force of impact resulting from a blow to the top, front, back, and sides of the head Safety helmet classes : To improve comprehension and usefulness, there are electrical-protective classifications for helmets as follows: Class G – General helmet: Designed to reduce exposure to low voltage conductors, proof tested at 2200V Class E – Electrical helmet: Designed to reduce exposure to high voltage conductors, proof tested at 20,000V Class C – Conductive helmet: Not intended to provide protection against contact with electrical conductors Operating temperature range : Basic temperature applications from -18°C (0°F) to 49°C (120°F) – No special marking on the helmet Low-temperature applications down to -30°C (-22°F) – Labeling on the helmet “LT” High-temperature applications up to 60°C (140°F) – Labeling on the helmet “HT” Additionally, all safety helmets must feature a hard-outer shell and a lining that absorbs shock and incorporates a headband. Straps should suspend from the shell about 1-1¼ inches. It is important to know that all safety helmets that adhere to ANSI/ISEA standards should be permanently marked with the manufacturer, the date of manufacture, ANSI designation, the Type and Class designation, and the head size range on the inside of the helmet shell. If your current safety helmet label is missing or is no longer legible, it is recommended that you replace your safety helmet as soon as possible. EN standards – Europe EN397 : The European standard code of practice (EN 397) provides guidance for manufacturers of safety helmets to ensure that minimum material grades are used. It also establishes the requirements for the testing of 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. The helmet will comprise of two main parts – the hard outer protective shell and the inner harness. All helmets certified according to EN 397 must meet these requirements: Shock absorption, vertical Penetration resistance (against sharp and pointed objects) Flame resistance Chin strap attachment: chin strap releases at minimum 150N (Newtons) and maximum 250N Additional specifications are provided for ear muff attachment points and chin strap attachment points. EN50365 : Standard covers insulating helmets aimed at use on low voltage installations, which must provide protection against electric shocks and prevention of dangerous electric current passing through the head. Requirements include: All helmets must also meet the requirements in accordance with EN 397 Protection against alternating voltage of up to 1000 V (AC) or direct voltage up to 1500 V (DC) Insulating helmets must not contain any conductive parts Air vents (if available) must not allow any accidental contact with live parts EN14052 : Standard covers high-performance industrial helmets, which must provide protection against falling objects and lateral impact along with the resulting damage to the brain, skull, and neck. Requirements include: Shock absorption, vertical, and lateral Penetration resistance, vertical, and lateral Fastening system yield: Chin strap yields at minimum 150N and maximum 250 N Fastening system effectiveness: During the shock absorption and penetration test, the helmet must not become detached from the test head Flame resistance EN12492 : Helmets for mountaineers must provide protection against hazards that may occur during activities undertaken by mountaineers. Requirements include: Shock absorption, vertical, frontal, lateral, dorsal Penetration resistance Carrier element (chin strap releases at min. 500N) Strength of carrier element: Chin strap may exhibit maximum elongation of 25mm Carrier element effectiveness: Helmet must not slide from the head Read more about EN12492's standards as they pertain to climbing-style safety helmets in the U.S. here. CSA Z94.1 standard – Canada The performance criteria for head protection in Canada is provided in the Canadian Standards Association (CSA) Industrial Protective Headwear, Z94.1 which applies to the selection, maintenance, and use of industrial safety helmets in the construction, mining, public utilities, and forestry sectors. Along with optional tests, such as for reverse orientation, CSA Z94.1 requires six performance tests that must be met in order to assign a safety helmet type and class, which are: Dielectric Strength Impact Attenuation Penetration Resistance Passive Retention (Stability) Shell Flammability Liner Ignition Resistance Safety helmet types : The CSA Standard (Z94.1) tests for Type 1 and Type 2 safety helmets include dielectric strength, impact attenuation, penetration resistance, passive retention, shell flammability, and liner ignition resistance (typically only Type 2 for lateral impact). 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 Type 2: Crown and lateral headwear – Designed for applications where there is potential impact on the crown and lateral areas of the head, where moving objects are present, and when the hazard assessment cannot determine the type Safety helmet classes : To improve comprehension and usefulness, the following designations refer to impact and penetration protection: Class G - General helmet: Headwear is non-conducting and is required to pass the dielectric strength test of 2,200 volts for 1 minute Class E - Electrical helmet: Headwear is non-conducting and is required to pass the dielectric strength test of 20,000 volts for 3 minutes Class C - Conductive helmet: Headwear does not provide dielectric protection 77.1710 standard – MSHA PPE requirements 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. Like OSHA, the agency’s regulatory authority is derived from a specific law, which the agency, in turn, enforces. MSHA carries out provisions of the Federal Mine Safety and Health Act of 1977, as well as administers the Mine Improvement and Emergency Response Act of 2006, which further expanded requirements and sanctions for mines. Mining safety helmet standards : Regarding protective clothing requirements, MSHA has its own PPE standard under 77.1710, and Section (d) specifies the need for head protection from falling objects and to protect miners against electrical shock or burn.
