Standard EN 1149-5 protection against explosion hazard

The standard is frequently applied in the following applicable market segments:

Chemical industry
Chemical processing industry
Transportation
Oil and Gas Extraction
Nuts

The general requirements of protective clothing for anti-static clothing must also comply with ISO13688

The EN 1149-5 standard has a lightning bolt as its symbol. This standard specifies the requirements of electrically conductive work clothes. This safety clothing is part of a completely grounded system (including in combination with conductive footwear). The anti-static clothing prevents the formation of sparks, which also prevents explosions.

Safety clothing with this standard is only accepted if it is combined with the standard (EN ISO 11612) for flame retardant clothing. This safety clothing is worn in potentially explosive areas. When there is a risk of an explosion, there is also a risk of fire. Safety clothing that complies with the EN1149-5 standard is often used by companies that must comply with the ATEX directive.

User instruction standard EN-1149-5

The user instructions for the EN 1149-5 standard always contain the following warning:

The person wearing the clothing must be grounded. This can be done by wearing conductive footwear. Anti-static clothing must not be opened or removed in a potentially explosive atmosphere. Anti-static clothing should not be used in an oxygen-enriched environment without consulting the safety officer. Antistatic clothing must cover non-antistatic clothing and materials during all possible working conditions. The antistatic effect can be reduced by wear and cleaning of anti-static clothing and materials. If in doubt, the clothing should be replaced.

A person can become electrically charged because the human body can behave like an electrical conductor. This can be caused by friction. Examples of this are: when walking around on an insulated floor or when there is contact with a charged electronic component or material, friction occurs. It can also be caused by induction effects of clothing charging. The electrical charge can be so high that sparks can even occur. This could cause a fire or explosion in a potentially explosive environment.
