The choice of helmet will depend on the type of work being undertaken and the environment in which it will be used. An EN397 weaker chinstrap may be more appropriate in places where there is a risk of snagging and thus a chocking hazard (such as in a confined space). Similarly, where it is important to ensure the helmet does not come off during a fall, such as, when there may be multiple impacts in a fall, the stronger EN12492 may be deemed most appropriate. For rope access, as noted in the IRATA ICOP 2.7.12, 'Users should check carefully the performance of industrial helmets conforming to European Standard EN397 as they might not have the all the performance requirements for the safety of rope access technicians, e.g. front, side and rear energy absorption capacity (not specified in EN397); appropriate chinstrap and fastening arrangement; low temperature use and ventilation (optional in EN397). Helmets utilizing expanded polystyrene shells (common in helmets conforming to European Standard EN12492) are unlikely to withstand the rigours of industrial use and, therefore, are generally not recommended'.
