The DUON has been successfully tested following accelerated UV exposure (the equivalent of 25 years in Northern Europe or 10 years anywhere in the world including Saudi Arabia). This was based on 40 hours per week average exposure.
The DUON’s maximum lifespan has been increased to 10 years use. Previously this was limited to 5 years use and 5 years storage (a total of 10 years).
MH01 – DUON™ standard – unvented EN 397
MH02 – DUON Air™ – vented, – EN 397 & EN 12492:
DUON Air™ vented height safety helmet is a high specification helmet with dual certification, meeting both industrial and climbing standards. It is the first safety helmet to meet all of the technical requirements for working at height and confined space.
The DUON-Air vented version has additional vents that can be switched to give conformity with either standard. All switching is carried out without tools.
- EN397 (‘industrial’) has a weak chinstrap to prevent injury if the helmet becomes trapped in machinery etc. and small vents to prevent items such as sparks hitting the wearer.
- EN12492 (‘mountaineering’) has a strong chinstrap so the helmet stays in place in a fall – protecting the head, and large vents to help prevent workers getting too hot – an occupational health improvement.
