Robson Bulk and Site Service Ltd. are fully certified to Design and Supply Bulk Materials Handling Equipment and Protective Systems for use in Potentially Explosive Atmospheres in accordance with the ATEX Directive 2014/34/EU.

So what is ATEX....

ATEX comes from the description of the hazardous materials in question, as written in French — “Appareils destinés à être utilisés en ATmosphères EXplosives.” The translation into English reads, “Devices intended for use in explosive atmospheres.”

ATEX designates hazardous materials which are potentially explosive. It imposes requirements for companies that handle and transport those dangerous materials, and it requires those companies to protect their employees from the risk of explosion.

ATEX is applicable in atmospheres where explosions can occur because of dust, vapours or gases that are likely to ignite or detonate. So, it applies to most workplaces that use or store flammable or explosive materials — for example, factories that use flammable products or generate combustible clouds of dust. Other examples of workplace operations where ATEX is likely to apply include chemical processing, paint spraying, sugar production and milk drying.

Under the ATEX directive, workplaces must classify any areas where explosive atmospheres are likely into zones. The likelihood that an explosive atmosphere will develop, as well as how long the explosive atmosphere will persist if it does develop, this determines the classification, size and location of the zone.
For instance, classification zones exist for explosive hazards like dust and fibres: -

• Zone 20 - indicates areas where explosive atmospheres containing a cloud of combustible dust will occur frequently or for extended periods.
• Zone 21 - indicates areas where explosive atmospheres containing a cloud of combustible dust will occur sometimes, but not extensively.
• Zone 22 - indicates areas where explosive atmospheres containing a cloud of combustible dust will occur infrequently or for short durations.

Similar classification zones exist for other explosive hazards like gas, vapour and mist :-
• Zone 0 - is the classification given to areas where explosive atmospheres containing hazardous gas, vapour or mist will occur frequently or for extended periods.
• Zone 1 - is the classification given to areas where explosive atmospheres containing hazardous gas, vapour or mist will occur sometimes, but not extensively.
• Zone 2 - is the classification given to areas where explosive atmospheres containing hazardous gas, vapour or mist will occur infrequently or for short durations.

ATEX certification is a requirement to ensure safety in the workplace by determining whether equipment is suitable for operation in a potentially explosive environment. Robson’s certification has been issued by ExVertitas, an impartial third-party organisation that provides testing as part of the certification process. Certified equipment receives a “CE” marking to indicate compliance and an additional “Ex” marking to indicate official certification under the ATEX directive.
