JSP’s EVO®5 Dualswitch™ is the ONLY helmet which is certified to both EN397 and EN12492 on one certificate, with the ability to change between the two standards easily at the flick of a switch. This changes the retention strength of the helmet’s fully adjustable 4-point chinstrap to give conformity to either the Construction Helmet EN397 or the Climbing Helmet standard of EN12492 for working at height.
Simply flick the switch up when working at ground level to give the chinstrap a release force between 15-25kg for EN397 so the helmet can release if snagged or switch down to give the chinstrap a release force of greater than 50kg for EN12492 to limit the risk of losing the helmet in a fall from height.
The patent pending EVO®5 Dualswitch™ meets all requirements of the ANSI Z89.1-2009 Type I Class C for helmet safety as well as the Canadian CSA Z94.1-05 Type 1 Class C standards. EN 397 and EN 12492 standards are also met with the robust Expanded Polypropylene liner for class leading impact protection, as are the EN 50365 requirements for electrical insulation when the chinstrap is set to EN397 position. It will also meet the optional requirements of the EN 397 standard for lateral deformation and use in low temperatures.
The EVO®5 safety helmet features an extremely robust ABS shell designed for superior protection and an easy to use Revolution® wheel ratchet with a 3D adjustment harness, which offers 1-2-3 point depth settings for a perfect fit. The distinctive five stripe design and the JSP shield shape is a registered badge of trade origin and internationally recognised as a mark of quality.
Universal attachment slots enable fitting of the many Surefit™ helmet accessories JSP offer, including safety visors, Sonis® ear defenders and the Evospec® integrated eyewear. CR2™ reflective material can be added to increase worker visibility.
