What safety helmet can I use for working with electrical hazards?
Electrical protection is an optional performance feature for safety helmets, which can be offered at varying levels under several different standards.
EN 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 offering 1000V a.c. electrical insulation. Due to the nature of the test, EN 50365 can be applied to vented and non-vented helmets.?
Other standards
The American national industrial head protection standard,?ANSI/ISEA Z89.1, sets out three classes relating to electrical properties:
-???Class C?– Conductive – No electrical testing
-???Class G?– General use – Tested at 2200V
-???Class E?– Electrical – Tested at 20,000V (2kV)
ANSI Z89.1 can be applied in the UK and Europe, in addition to the relevant EN standards, for increased electrical protection.?
Selecting helmets with electrical protection
It is important to check the electrical protection offered by different products carefully and select a helmet that provides appropriate protection for the task and risks.
Markings on the helmet detail conforming standards and performance properties, with further information available in user instructions and on request from the manufacturer.?
