The European standard EN 1149 defines the requirements for electrically conductive clothing. For example, clothing together with electrically conductive shoes form part of a fully grounded system. Such protective clothing protects against the risk of sparks and explosions. Clothing produced according to this standard is accepted only in conjunction with the TS EN ISO 11612 standard, which is a standard for flame retardant clothing.
Clothes to which the TS EN 1149 standard applies reduce the electrostatic charge of personnel and the formation of flammable static sparks. These protective clothing should be used in work environments where an explosive atmosphere may occur. This standard describes electrostatic requirements for clothing.
This type of clothing is used in work environments where there is a risk of explosion and fire. However, it is not suitable for work environments enriched with oxygen. It does not provide absolute protection against electric shock. In particular, companies that have to comply with the ATEX directives must wear clothing that meets the TS EN 1149-5 standard. ATEX is an abbreviation derived from the expression "ATmosphere Explosible".
