EN 50365:2023 covers electrically insulating helmets for live working on low- and medium-voltage installations. The current European edition includes the 2024 corrigendum.

Live-working or proximity tasks on electrical installations where the risk assessment requires electrically insulating head protection.

Verify EN 50365 marking, manufacturer instructions and voltage/application limits; EN 397 marking alone is not sufficient evidence of electrical insulation.
A class code is not a selection decision by itself. Interpret it together with task-specific risk assessment and manufacturer data.

Helmet electrical-insulation performance is used within manufacturer-declared live-working application limits.

Industrial helmet marking alone is not sufficient evidence of electrical insulation.

For specialist electrical use, the relevant insulating standard is verified separately.
Live-working electrical insulation requirements must be verified separately.
Check EN 50365 marking plus manufacturer voltage/use limits.





Use for quick pre-checks. It does not replace certification, competent inspection or task-specific risk assessment.
Any crack, puncture or surface contamination?
Selecting a helmet marked only EN 397 for live electrical work.
Check EN 50365 marking plus manufacturer voltage/use limits.
Any crack, puncture or surface contamination?
Are EN 50365 marking and manufacturer limits legible?
Is the helmet clean/dry and within manufacturer instructions?
Has other electrical PPE required for the task been selected separately?
