On high-risk industrial sites, ATEX zoning is an obligation. This operation consists of determining the zones whose atmosphere is most likely to trigger an explosion. This is why it is called, EXplosive atmosphere.
In the most dangerous areas, the presence of static electricity must be taken into account. Indeed, the formation of electrostatic charges must be carefully monitored to ensure the safety of personnel and the durability of equipment.
What PPE should you choose to protect yourself against electrostatic risks in potentially explosive atmospheres? Our experts can answer your questions.
Electrostatic discharge and electrostatic risk
What is an electrostatic discharge?
An electrostatic discharge (ESD) is generated whenever two bodies or materials with different static charges come into contact and then separate. This phenomenon is known as triboelectricity.
During this meeting, one of the two elements gains electrons and the other loses them, creating a sudden difference in electrical potential. The electrostatic phenomenon is formed when positive and negative charges are combined.
Although these energy transfers are not perceptible, they are nonetheless permanent and can manifest themselves as micro-sparks.
How to identify the electrostatic hazard?
ESD is only dangerous if the static charge accumulates for too long, especially on insulated metal equipment, insulating materials, powders and non-conductive liquids.
In ATEX zones, there is an electrostatic risk due to the presence of gases, liquids or powders. Therefore, if an electrostatic discharge occurs in an ATEX zone, then an ignition and/or explosion will occur
Consequently, the electrostatique risk is present and threatens both the operation of equipment and the health and safety of personnel.
PPE in electrostatic or explosive zones
To protect workers in electrostatic or ATEX zones, several specific items of equipment are required:
- Antistatic protective gloves (NF EN 16530 standard): these enable electrostatic charges to be dissipated rapidly when in contact with a live object.
- Antistatic protective clothes (NF EN 1149-5 standard): clothing designed with electrostatic properties. The EN 1149-1 standard.
The FIT4PROTOUCH, a model adapted to electrostatic zones
Because we are committed to creating products adapted to all risks and all uses, we have designed a model of protective gloves specially intended for applications involving an electrostatic risk.
This is how the FIT4PROTOUCH was born, a reference designed for handling sharp parts but also for assembly operations (EN388 mechanical standard).
Knitted in HPPE/carbon weave and coated with polyurethane, the FIT4PROTOUCH has a technological mesh to protect the wearer from electrostatic discharges and not to break the grounding chain. In fact, this model meets the requirements of the EN 16530 standard for electrostatic protection.
In addition, the FIT4PROTOUCH glove is equipped with our touch technology, which is ideal for safe handling of your industrial machinery
