EN 397: Understanding the European Standard for Industrial Safety Helmets

When it comes to workplace safety, one of the most critical aspects is protecting your head from potential hazards. That’s where the EN 397 standard comes in. This standard outlines the requirements for industrial safety helmets, ensuring that they provide adequate protection against impact, penetration, and other potential dangers.

After guiding you through the European Standards for ear defenders, hi-vis clothing, safety footwear, waterproof workwear, chemical resistant and cut resistant gloves, it’s now time to take a closer look at the EN 397 standard. Whether you work in construction, manufacturing, or any other industry that requires the use of safety helmets, this information is essential for your safety and well-being. So, let’s dive in and explore the world of EN 397 standard together.

Understanding the Importance of Head Protection

Head protection is essential in any workplace where there is a risk of head injury. These injuries can occur due to various factors, such as falling objects, slips and falls, or electrical hazards. According to the Occupational Safety and Health Administration (OSHA), head injuries account for a significant percentage of all workplace injuries and fatalities. Therefore, it’s essential to take measures to protect your head from potential hazards.

One of the most effective ways to protect your head at work is by wearing a safety helmet. A safety helmet is a type of personal protective equipment (PPE) that is designed to protect your head from impact, penetration, and electrical hazards. In Europe, the EN 397 standard outlines the requirements for industrial safety helmets. This standard specifies the physical and performance requirements for safety helmets, including their shock-absorbing capacity, resistance to penetration, and resistance to flame.

EN 397 Standard Specifications and Requirements

The EN 397 standard specifies the following requirements for industrial safety helmets:

Shock-Absorbing Capacity

The safety helmet must be able to absorb the shock caused by an impact. The helmet is tested by dropping a mass of 5kg onto it from a height of 1 meter, and the force is received is then calculated. The maximum force transmitted to the head should not exceed 5kN. The test is repeated several times, including low and high temperatures, helmets that have been submerged in water and exposed to UV rays.

Resistance to Penetration

The safety helmet should be able to resist penetration by a pointed object. The helmet is tested by dropping a pointed 3kg striker onto the hard hat. The helmet should not be penetrated, and the maximum force transmitted to the head should not exceed 5kN. Same as for the shock -absorption capacity, the helmet is tested under different conditions, including low and high temperatures, water immersion and UV rays aging.

Resistance to Flame

The safety helmet must be able to resist the effects of a flame. The helmet is tested by exposing it to a flame for 10 seconds. The helmet should not catch fire or transmit heat to the head.

The EN 397 standard also specifies requirements for the chinstrap, the size and weight of the helmet, and the manufacturer’s instructions and markings.

Chinstrap

EN 397 compliant hard hats come with a chinstrap that helps to keep the helmet in place. The chinstrap ensures that the helmet does not fall off during an impact, providing maximum protection to the head. At the same time, the chinstrap must release when force is applied to ensure the helmet doesn’t strangle the wearer. To comply with the EN 397 Standard, it must release at minimum 150N and maximum 250N.

Maintaining EN 397 Compliant Hard Hats

Maintaining your EN 397 compliant hard hat is essential to ensure maximum protection. Here are some tips on how to maintain your hard hat:

Inspect Regularly: Inspect your hard hat regularly for signs of wear and tear. Check for cracks, dents, or other damage that may affect its performance. If you notice any damage, replace the hard hat immediately.

Clean Regularly: Clean your hard hat regularly with mild soap and water. Avoid using harsh chemicals or abrasive cleaners that may damage the helmet.

Store Properly: Store your hard hat in a cool, dry place away from direct sunlight. Avoid storing the hard hat in a place where it may be exposed to chemicals or other harmful substances.

Now that you know how the EN 397 standard works, remember that when selecting a hard hat, you should always consider factors such as the type of work, size and fit, material, brand, and price.
