EN 1149-5 certified rainwear and workwear protects against the risk of electrostatic discharge (ESD). Clothing with EN 1149-5 certification is designed to prevent or limit the build-up of static electricity on the wearer, reducing the risk of spark discharges that can ignite flammable substances or cause explosions in hazardous work environments.

This standard is important in industries such as petrochemical, gas and mining industries where there is a high risk of explosions due to static electricity.
