What is the difference between EN 397 and EN 12492 ...

While on site, it is important to wear the proper head protection. Selecting the right type of helmet for the task is vital to protect against different types of risk. Two widely applied helmet standards with important differences in performance requirements are EN 397 and EN .  Companies are increasingly adopting safety helmets meeting EN to protect against side impact. On some sites, this type of helmet is now mandatory.

You can find more information on our web, so please take a look.

 The main difference between the two head protection standards is the intended usage, which results in different requirements. EN 397 specifies the requirements for industrial safety helmets, which primarily provide protection against falling objects, whereas EN covers helmets for use in mountaineering which includes a risk of swinging and repeated all-round impact.

EN 397 &#; Industrial safety helmets

This standard goes back over 50 years and testing is only carried out on the top of the helmet. A 49J impact only to the crown of the helmet is required for shock absorption, and a penetration test is conducted with a 3kg conical striker from 1m. There are no side, front, or rear impact requirements in this standard only an optional lateral rigidity test, which is a slow, progressive force loading followed by measurement of any deformation.

 Additionally, the standard includes other options such as molten metal resistance and 440V electrical insulation.

 EN 397 does not include a mandatory requirement for chin straps. Optional chin straps must release under a force of 150 &#; 250N.

EN &#; Helmets for mountaineers

Helmets complying to the mountaineering standard are impact tested with two 5kg strikers. A hemispherical striker is dropped from 2m onto the crown of the helmet and a flat striker from 0.5m on to the front, rear, and side by tilting the headform to 30°. In all cases, the transmitted force through the neck of the headform must not exceed 10kN. Two penetration tests with a 3kg pointed striker are also performed within a 50mm radius of the helmet&#;s crown, ensuring the striker does not contact the headform.

 Chin straps are mandatory for EN helmets. The retention system is tested to ensure the strap does not break or stretch when tested with a force of 500N.

 Though the standard refers to &#;mountaineering&#; helmets, EN helmets are also used for other work at height due to the type of protection offered.

EN helmets have different requirements for the harness or cradle, which must incorporate an integral chin strap that does not break or stretch under force. EN 397 helmets, however, do not require a mandatory chin strap, and an optional chin strap must break under a force of between 150N and 250N to reduce the risk of a wearer being injured by becoming caught in machinery in an industrial environment. EN helmets also feature an internal impact liner to improve side impact protection.

 With the growing need for a helmet to meet both standards, JSP developed the Dualswitch&#; system which allows the user to change between the two standards by flicking a switch. EVO®5 Dualswitch&#; and EVO® Vista®Dualswitch&#; helmets are fully tested and certified to both EN 397 and EN , plus the EN electrical standard.

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.
