EN 342 is the European standard for clothing ensembles that protect against cold. It is relevant for cold stores, freezer work, outdoor work and other jobs where workers face prolonged low temperatures.
What does EN 342 cover?
EN 342 focuses on passive cold protection: how well a clothing ensemble insulates the wearer, blocks air movement and, where tested, resists water penetration. For less extreme cool environments, EN 14058 may be relevant.
When is it useful?
If employees work in cold rooms, freezers or outdoor winter conditions, employers should assess whether cold-protection clothing is required. The correct choice depends on temperature, air movement, exposure time and physical activity.
Passive insulation versus active heat
EN 342 measures passive protection. Heated clothing adds active warmth to the body. The two can work together: a heated vest can act as a warm core layer under suitable cold-protection clothing, provided it does not interfere with required PPE.
Important buying note
A heated garment is not automatically EN 342 certified. If a certified clothing ensemble is required, check product documentation and use the heated layer only as an additional comfort measure unless it is specifically certified.
FAQ
Is EN 342 Irish law?
EN 342 is a European standard, not a standalone legal rule for every workplace. It can help employers choose suitable clothing when risk assessment shows cold protection is needed.
Can a heated bodywarmer replace certified cold clothing?
Not automatically. It may support warmth, but certified protection depends on the specific product and clothing ensemble.
