Features ➣ excellent resistance against weather influences ➣ suitable for almost every application ➣ heavy duty quality ➣ rather heavy ➣ more expensive than polyethylene or polypropylene Even if they are made of the same material, safety hel- mets have many different features providing specific user benefits, such as: ➤ Weight: Some helmets are lighter than others. A light- weight helmet may provide more comfort during pro- longed periods of use. ➤ Harness: A helmet can have either a basic poly- ethylene harness or a more comfortable textile webbing harness. ➤ Sweatband: A helmet can have either none, a stand- ard or a high absorbent sweatband for improved com- fort during use. ➤ Ventilation: Some helmets are ventilated, providing cooling airflow during use. ➤ Badging: Some helmet designs allow for a larger front badging area, for an enhanced corporate image. ➤ Peaks: Peak lengths can vary – a reduced peak is available for improved upward visibility. ➤ Retro-Reflective Surfaces: Reflective surfaces that provide greater visibility of the wearer in low light condi- tions. Although there is no legislation governing the expected lifespan of safety helmets, it is strongly recommended that they are replaced every five years. Excessive wear and tear can drastically reduce this period. Helmets that have been abused, cut or scratched should be discarded imme- diately. The cost of a new helmet is far less than the cost of compensation for injury - or for an employee who may pay with his life because of inadequate protection. 3.0 Bump Protection Bump caps are used in areas of restricted head space where accidental bumping of the head could be involved. They are designed for protection against minor bumps and scratches, or as sanitary headwear in food process- ing plants. They are not used to protect against impact or electrical shock. When furnished with a solid polypropyl- ene shell, they are called bump guards and can also be used to prevent minor impacts. Bump guards also feature a harness, like safety helmets. They are not a substitute for safety helmets and must not be used to protect the head from falling objects. Legislations for further information: EN 397 specifies physical and performance require- ments of industrial safety helmets. Certain tests are mandatory if the product is to receive EN 397 approval. These cover: ➣ Shock absorption ➣ Resistance to penetration ➣ Flame resistance ➣ Chinstrap anchorage A manufacturer can choose to submit his products to additional optional tests. Such tests could lead to one or more of these markings appearing on a helmet: -20°/-30°C The helmet will provide some protection when worn in an environment at or above this temper- ature. -40°C ultra low temperature (outside of EN 397). 440V a.c. The helmet will protect against short-term, accidental contact with live electrical conductors up to this voltage. LD The helmet will provide some resistance to lateral compressive (non-impact) loads. MM Molten Metal splash test EN 14052 Builds on EN 397 to include more onerous tests and requirements, but also to include require- ments for additional impact protection to the front, rear and sides of the head. It also includes performance tests for the retention system (typically headband and chin strap), not typically included in EN 397. EN 50365 Electrically insulating helmets for use on low voltage installations. EN 812 is the standard for Industrial Bump Caps, which are intended to provide protection against bumps caused by walking into hazardous projections. A Bump Cap does not provide protection against fall- ing or thrown objects and should not be used where a safety helmet is required.
