HEAD PROTECTION Q&A HEAD PROTECTION Q&A

Q I have been told by a member of staff that I can wear a bump cap instead of an
industrial safety helmet, is this acceptable?

A No, bump caps and industrial safety helmets are made to different standards and serve different purposes.
Bump caps are tested and certified to EN 812, providing protection to the wearer against the effects of

striking their head against hard, stationary objects, but do not offer protection against falling masses.

Industrial safety helmets provide head protection to EN 397 and are designed to protect the wearer from

falling masses. Bump caps should not be worn where a safety helmet is required.

Q Which helmets are suitable for working at height?

A Helmets conforming to EN 12492 are suitable for working at height. This standard sets out requirements

for mountaineering helmets that are often used in industrial activities involving work at height. JSP Evolite®
Skyworker™, EVO®5 DualSwitch™, and EVO® VISTA® DualSwitch™ helmets conform to EN 12492.

Q Which helmets provide electrical protection?

A Electrical protection is an optional performance feature for safety helmets, which can be offered at varying levels

under several different standards. EN 397 and EN 14052 include an optional 440V a.c. electrical resistance test
which can be applied to non-vented helmets. EN 50365 is an additional standard for helmets offering 1000V a.c.
electrical insulation which can be applied to vented and non-vented helmets due to the nature of the test.
See pages 11 - 12 and testing & performance information given on each product page to check if a helmet offers
electrical protection.

Q What is the difference between EN397 and EN12492 helmets? Can I have both?

A The main difference between these two head protection standards is the intended usage, which results in

different requirements. EN 397 specifies the requirements for industrial safety helmets, which primarily
provide protection against falling objects, whereas EN 12492 covers helmets for use in mountaineering which
includes a risk of swinging and repeated all-round impact. EN 12492 helmets have different requirements
for the harness or cradle, which must incorporate an integral chinstrap that does not break or stretch under
force. EN 397 helmets, however, do not require a mandatory chinstrap, and an optional chinstrap must break
under a force of between 150N and 250N to reduce the risk of a wearer being injured by becoming caught in
machinery in an industrial environment. EN 12492 helmets also feature an internal impact liner to improve
side impact protection. With the growing need for a helmet to meet both standards, JSP developed the
Dualswitch™ system which allows the user to change between the two standards by flicking a switch. EVO®5
Dualswitch™ and EVO® Vista® Dualswitch™ helmets are fully tested and certified to both EN 397 and EN
12492, and the EN 50365 electrical standard.
