Two Standards, One Switch.
The EVO®5 Dualswitch™ climbing helmet is the only industrial safety helmet to be fully certified to both EN397 and EN12492 on a single CE certificate, with the ability to change between the two standards easily at the flick of a switch making the harness either 'strong' or 'weak'.
Switching to EN397 mode sets the harness release force to less than 25daN, (250N), Allowing the chinstrap to release if snagged to avoid risk of choking.
Switching to EN12492 mode sets the harness release force to more than 25daN, (250N), Preventing the chinstrap from releasing and limiting the risk of losing your helmet whilst working at height.
