A potentially explosive atmosphere is composed of a mixture of gases, vapours, mists or dusts which can ignite under certain operating conditions.
For the equipment and protective systems intended for use in potentially explosive atmospheres, ATEX Directive 2014/34/EU provides the technical requirements to be applied and the relevant conformity assessment procedures before placing this equipment on the European market.
On the other hand, Directive 1999/92/EC deals with the minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres. A non-binding guide to good practice for implementing Directive 1999/92/EC released by the European Commission is available.
FEA also provides specific guidance in the FEA Guidelines on Basic Safety Requirements in Aerosol Manufacturing.
