HOW DOES HELMET WORK

Helmets: How they Work, and What Standards Do Summary: Here are some basic ideas on helmets including design principles and what they can or can't do for you. We also explain what is included in standards for helmet testing. Why use a  helmet ? Helmets are useful as safety gear to prevent injuries in an uncontrolled environment. If you can't prevent a crash or impact, but you know it will occur, a helmet can prevent or minimize injury to the head and brain. We can not emphasize enough that the first step in preventing injury is to minimize the probability of crashing or being impacted. Not hitting something hard is infinitely better than hitting with a helmet on! There are many reasons for that statement. No helmet can protect against all possible impacts, and the impact may exceed the helmet's protection. No helmet protects any part of the body that it does not cover, so even if the head injury is avoided you may have a smushed face, broken bones or worse. Safety a

HOW TO CHOOSE THE BEST CLIMBING HELMET

HOW TO CHOOSE THE BEST CLIMBING HELMET WEAR-ABILITY What good does buying a  climbing helmet  do if you don’t wear it? Above all, pick a helmet that is comfortable and attractive in your eyes because if, on the other hand, you get an uncomfortable and unattractive helmet you will probably never wear it and it will do you no good.   PROTECTIVENESS Consider the type of climbing you’ll be doing. Are you at an increased risk of hitting your head or having something (e.g. rock, ice) fall onto your head? Or do you simply need a layer of cranium protection for the worst case scenario?   If your climbing helmet would be seeing lots of abuse then opt for a durable and more protective helmet. Otherwise, you might be able to get away with a lighter option.   Weight Weight can be an important criteria for gear selection depending on the type of climbing you’re doing. Those seeking to minimize climbing pack weight for whatever reason should look for  lightweight climbing helm

EN12492 standard

EN12492 Impact / Shock Absorption Similar to both industrial  helmets  and bump caps, mountaineering helmets are subjected to an impact from a falling mass onto a fixed headform. However, to reflect the nature of the use, additional impacts are required at the front, side and rear of the helmet. These impacts are carried out by tilting the headform on the rigid base at an angle of 60° (so that impacts are carried out at 30° from the horizontal plane of the headform). Impacts are carried out using two strikers, one flat and one hemispherical, each weighing 5kg. Helmets are impacted using the hemispherical striker dropped from a height of 2 metres, and at the front, rear and sides using the flat striker dropped from a height of 500mm. In all cases, the transmitted force through the headform cannot exceed 10kN. Penetration As with industrial helmets and bump caps,  mountaineering helmet  are intended to provide protection against sharp / pointed objects, and so are test
