EN 1149-5: 2008: PROTECTIVE CLOTHING WITH ELECTROSTATIC PROPERTIES
This is the European Standard for garments that protect against electrostatic discharge in areas where there is a risk of explosion (e.g. ATEX Environments) where there is a risk that the garments could create sparks (source of ignition), which in turn could ignite explosive materials. Typical environments would include petrochemical refineries and fuel distribution companies.
Annex II, art. 2.3. of the ATEX directive 99/92/CE concerning the protection of workers likely to be exposed to the risk of explosive atmospheres says: “Workers must be provided with appropriate working clothing consisting of materials which do not give rise to electrical discharges that can ignite explosive atmospheres”.
There are several categories within EN 1149 that enable the final EN 1149 to be displayed on an EN 1149-5 certified CE marked garment. The fabric and components are tested according to EN 1149-1 (surface resistivity) or EN 1149-3 (charge decay). There are also design critical requirements for garments certified to this EN Norm including the covering of components on the exterior of the garment, and limitations of the dimensions of some components such as reflective tape.
Wearing your Antistatic PPE
During use, the garments must be fastened at the front at all times and the wrist fastenings secured close to the wrist. If 2 Part garments are to be worn i.e. a Jacket, another item e.g. a Trouser, also conforming to the same standards must also be worn. Non-conforming garments worn over antistatic garments would eliminate the effectiveness of the garments. Further details regarding your Antistatic PPE can be found on the User Information sheet contained within the product packaging.
