JSP’s DualSwitch™ technology is fully certified to both EN 397 and EN 12492, with the ability to change between the two standards easily at the flick of a switch. The innovative system is available with EVO®5 and EVO® Vista® range helmets, for use at ground level (EN 397) or at height (EN 12492) without the need to swap the harness.
Working at height - switch down
- EN 12492
- ANSI / ISEA Z89.1
The chinstrap release force of EN12492 is greater than 500 Newtons. This limits the risk of losing the helmet during a fall.
Working on the ground - switch up
- EN 397
- EN 50365
- ANSI / ISEA Z89.1
The chinstrap release force of EN397 is between 150 and 250 Newtons. This limits the risk of choking, the chinstrap has been designed to release if snagged. Have any more head protection questions?
