In high-risk environments like oil and gas, pharmaceuticals, and food processing, managing the dangers of potentially explosive atmospheres is critical. That's where ATEX-certified equipment comes in, providing essential protection in settings where flammable gases, mists, vapours or dust are present.
What is ATEX?
ATEX, short for “Atmosphères Explosibles,” is the European Union’s safety directive for equipment used in potentially explosive environments. Far from just a compliance measure, ATEX-certified products are engineered to prevent ignition, safeguarding both people and property.
Where Are Hazardous Environments Found?
Under the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR), it is an employer's responsibility to protect the safety of staff and the public against the risk of fire and explosions in the workplace. Hazardous environments can be present in a wide range of industries, including:
- Oil, gas and petrochemical facilities
- Flour and grain mills
- Waste management sites
- Distilleries
- Pharmaceuticals
- Mining operations
- Vehicle paint spray shops
To meet the strict safety requirements, ATEX-certified equipment such as drives, controls, lighting and ventilation systems are indispensable.

Understanding ATEX Zones: A Quick Guide
To ensure the correct level of protection, ATEX categorises different hazardous areas based on the likelihood of explosive atmospheres.
Gas - zones 0, 1, 2
Dust - zones 20, 21, 22
- Zone 0/20 - Most hazardous: explosive atmosphere is continuously present or present for long periods
- Zone 1/21 - Hazardous: explosive atmosphere is likely to occur during normal operation
- Zone 2/22 - Potentially hazardous: explosive atmosphere is not likely to occur during normal operation and, if it does occur, will only exist for a short time
Installation & Compliance
Conforming to the ATEX directive requires the employer or owner of the premises to prepare a mandatory risk assessment to identify the types of hazardous materials and required level of protection. The door manufacturer is responsible for ensuring that equipment sited in potentially hazardous areas complies with the ATEX directive to eliminate potential sources of ignition.
To ensure the whole system, including wiring, meets the necessary safety requirements, all ATEX-compliant drives and controls are supplied without cabling; installation must be carried out by a qualified ATEX electrician.
Customisation options such as photocells, safety edges, pushbuttons and audio-visual alerts allow businesses to tailor their ATEX setups for maximum efficiency and safety.
The Costs of Neglecting ATEX
Ignoring ATEX standards can lead to:
- Safety hazards: Accidents and injuries
- Legal consequences: Fines and lawsuits
- Downtime: Expensive repairs and disruptions
- Property damage: Explosions and losses
