ATEX Assessment

The EU ATEX Directive requires operators to identify the potential for an unintended explosive atmosphere to exist on their plant. Operators must also assess the risks to personnel and reduce these risks, either by eliminating the formation of the explosive atmosphere or by ignition source control.

The latter is enforced by Hazardous Area Classification and this falls into RJM’s area of expertise in relation to fuels, which, by definition, are flammable. For example, the release of fuel gas, the formation of sprays or vapours from liquid fuels and the release of dust from solid fuels can all create potentially explosive atmospheres. The use of biomass in particular, with more aggressive explosive and ignition properties, has resulted in numerous fires and explosions on a number of power plants worldwide.

RJM’s engineers bring a combination of specialist fuel knowledge coupled with plant design and operations expertise to provide knowledgeable and pragmatic assessment of explosion risk. Consequently, they can carry out hazardous area assessments in accordance with the ATEX Directive, national or EU standards and relevant industry specific guidance.

RJM’s Principal Safety Engineer was at the forefront of ATEX compliance development for the power generation sector in the UK and is a joint author of the UK Power Industry’s Best Practice Guide – a document endorsed by the Health & Safety Executive  (HSE)  RJM’s solutions focus on appropriate implementation and robustness and offer reassurance to customers that their plants are operating as safely as possible.
