BS EN 1149 discusses the electrostatic properties of protective clothing. BS EN 1149-5 is an international standard on material performance and design requirements for protective clothing to ensure protection from workplace hazards.
BS EN 1149‑5 is the fifth part of a multi-part series that specifies material and design requirements for electrostatic dissipative protective clothing, including hoods and caps, used as part of a total earthed system, to avoid incendiary discharges, where the minimum ignition energy of an explosive atmosphere is not less than 0,016 mJ.
In the context of BS EN 1149‑5, a total earthed system is one in which personnel and other conductors are connected to the earth via a resistance of less than 108 Ω.
Note1: BS EN 1149‑5 does not apply to protection against mains voltages.
Note2: BS EN 1149‑5 does not include electrostatic dissipative protective gloves or footwear that are separate and not integral parts of garments.
Note3: The material and design requirements under BS EN 1149‑5 may not provide sufficient protection in oxygen-enriched flammable atmospheres.
BS EN 1149‑5 on material performance and design requirements for electrostatic properties of protective clothing are useful for:
PPE is equipment that will protect the end-user against health or safety risks at work. It can include items such as safety helmets, gloves, eye protection, high-visibility clothing, safety footwear, and safety harnesses.
BS EN 1149‑5 provides you with electrostatic requirements, material requirements, design requirements, material performance, and marking for electrostatic properties of protective clothing.
The requirements and performance provided by BS EN 1149‑5 assist in improving the quality of protective clothing and ensure protection to end-users from electrostatic hazards.
By adopting BS EN 1149‑5 the user can improve the efficacy of the protective clothing and help produce a product of higher standard and quality.
BS EN 1149‑5:2018 supersedes EN 1149-5:2008, which is withdrawn. BS EN 1149‑5:2018 has made some technical changes compared to the previous edition EN 1149-5:2008. These include:
