Rules for helmets
Industry, vertical work, rescue, climbing and mountaineering.
There are two european standards that refer to the helmets: IN‐397 and IN‐12492.
Helmets for industry (EN‐397): Essentially this standard requires that helmets present a housing made of polycarbonate of high resistance to mechanical shock, which if present barboquejo, it is release to be exercised at a tensile force greater than 25 daN (minimizing the damage to the operator if the helmet hooked during a fall or a descent), and that protect them from projections of metal in fusion, electrical hazard, deformation, lateral, and can be used at low temperatures.
Helmets for rescue, mountaineering and rock climbing (IN‐12492): This standard requires that helmets present a housing made of polycarbonate of high resistance to mechanical shock, the barboquejo is very resistant and only loosen to forces greater than 50 daN, and submit ventilation (being without protection from projections of metal in fusion and in front of the electrical hazard).
Helmets for vertical (Without specific regulation): vertical work does not have specific rules governing the characteristics of the helmets employees. However, it is obvious that a helmet for vertical work must carry barboquejo and must produce a casing resistant to mechanical shocks and deformation to the side. According to the nature of the tasks will be preferable to present ventilation or protection against the projections of metal in fusion and in front of the electrical risk.
The national association of companies of vertical works recommends strongly the certification‐397, since this approval is part of the consideration of the hull as a PPE (personal Protective Equipment), unlike the IN‐ 12492 which are not covered by the helmet as such.
