The EN 1149-5 standard for protection against explosion hazards

The standard is frequently applied in the following sectors:

  • Chemicals
  • Chemical processing
  • Transportation
  • Oil and Gas extraction
  • Utilities

The general requirements of anti-static protective clothing are set out in EN 340.

This standard has a lightning bolt symbol, with the EN 1149-5 standard below. This standard specifies the requirements of electrically conductive work clothing. This safety clothing is part of a total earthed system (combined with conductive footwear etc.). Anti-static clothing prevents the formation of sparks, so also prevents explosions.

Safety clothing with this standard is only accepted if it is combined with the standard (EN 531 or EN ISO 11612) for flame-retardant clothing. This safety clothing is worn in areas where there is an explosion hazard. Where there is a risk of an explosion, there is also a risk of fire. This safety clothing must not be used in oxygen-enriched environments, and does not protect against mains voltage. Safety clothing that complies with the EN 1149-5 standard is often used by companies that have to comply with the ATEX directive.

The user instructions must be in the language of the country where the product is sold, and the following warnings must be shown;

  • The person wearing the clothing must be earthed. This can be achieved by wearing conductive footwear.
  • Anti-static clothing must not be opened or taken off in a potentially explosive atmosphere.
  • Anti-static clothing may not be used in an oxygen-enriched environment without consulting the safety manager.
  • Anti-static clothing must cover non-static clothing and materials during all possible working conditions.
  • Wear and tear and washing anti-static clothing and materials can reduce the anti-static effect. If in doubt, replace the clothing.

A person can cause electrically charged because the human body can behave like an electrical conductor.

  • This can be caused by friction, such as walking on an insulated floor or touching an electrical component or material.
  • It can also be caused by the effects of induction on clothing that becomes charged. The electrostatic charge can become so high that it causes sparks, which can in turn cause a fire or explosion in a potentially explosive environment.
