An explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist or dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture.
The ATEX directives are not a precept and are constantly being revised and updated by the European Union Committee responsible for specifying the guidelines to be followed in every process which is deemed to be high risk.
There are two directives:
Directive 94/9/EC, which is concerned with producers of equipment, instrumentation and machinery etc.
Directive 99/92/CE, which is concerned with the final user.
Our extensive experience in working with these directives allows us to offer:
Detailed risk assessment using techniques such as Hazop, TRAC, EPSA and 5M.
The Optimisation of potentially explosive zones, in both flamable vapour and/or explosive dust.
Explosive zone calculation in accordance with standards EN 60079-10 and
Measurement of ventilation, static electricity and equipotentiality etc. in ATEX zones.
Monitoring the conformity of facilities or equipment when they are commissioned in ATEX zones.
Laboratory testing of the explosivity and flamabilty of liquid and dust products.
