Safety helmets can be divided into four categories based on the type of risk they protect against:
Type of head protection and norms
Industrial safety helmet (EN 397):
Protects the user's head against falling objects that can cause head injuries. Consists of helmet shell and interior, and has either a short or long brim depending on the type of work to be carried out. According to the standard, the helmets must be tested for shock absorption for falling objects and protection against penetration by sharp and pointed objects. Safety helmets may also have optional tests for additional types of risk such as very low temperatures (-20°C or -30°C), very high temperatures (+150°C), electrical insulation (440 VAC) and molten metal (MM).
Klatrehjelm for arbeid i høyden (EN 12492):
Protects against dangers that may arise for mountain climbers while working at height. Climbing helmets are also tested for falling objects and penetration. The chin strap is a requirement and must not be released with a force of at least 50 kN. Climbing helmets must also be ventilated.
Electrically insulated helmets (EN 50365):
Protection against electric shock when used when working under low-voltage installations such as alternating voltage of up to 1000 V (alternating current), or direct voltage of up to 1500 V (direct current). All helmets must also meet the requirements in accordance with EN 397. Insulating helmets must not contain any conductive parts. The ventilation openings (if available) must not be able to accidentally come into contact with live parts.
Light industrial safety helmet (EN812):
Light helmet, shock cap or bump cap consists of a cap with protective inserts, and protects the user's head against light impacts. Can only be used in a working environment where there is no danger of perishable objects. Bump caps provide good ventilation, great flexibility and protection against minor bumps and scratches to the head.
It is often necessary to have various additional equipment for a safety helmet. Hearing protection and visors are good examples of something that is often used. In addition, the additional equipment for the protective helmet must be adapted to the work environment the helmet will be used in. Wenaas has a wide selection of protective helmets and additional equipment, and will ensure that you always get the protective equipment you need. Perhaps a safety helmet with built-in eye protection is the right thing for you? Good availability of eye protection seems to contribute to a decrease in the number of eye injuries - which is very good.
