What is **BS EN 1149‑5-Material performance and design requirements for electrostatic properties of protective clothing about?**

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.

Who is **BS EN 1149‑5-Material performance and design requirements for electrostatic properties of protective clothing for**?

BS EN 1149‑5 on material performance and design requirements for electrostatic properties of protective clothing are useful for:

PPE manufacturers
PPE designers
PPE testing laboratories/test personnel
Occupational health and safety departments

Why should you use **BS EN 1149‑5-*Material performance and design requirements for electrostatic properties of protective clothing***?

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.

What is changed since the last update?

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:

The thickness of any non-dissipative layer forming the outermost surface of garments is limited to 2 mm
A requirement for earthing electrostatic dissipative garments is added to the design requirements
The thickness of any non-dissipative attachments to the outside of garments is limited to 2 mm and limits for area and/or width of non-dissipative attachments are added
Alignment of the informative Annex ZA related to the application of the (EU) Regulation 2016/425
