What we do

CompEx certification offers complete reassurance to employers and practitioners operating in potentially hazardous workplaces.

What we do

The CompEx scheme

The CompEx Scheme is the recognised global solution for validating the competency of staff working in all industries with potentially hazardous and explosive atmospheres. Our purpose is to support and promote workplace safety, by certifying personal competency.  CompEx is underpinned by international standards and is ideal for employees and contractors who work in explosive atmospheres, such as the gas, oil, chemical and pharmaceutical sectors.

CompEx is the only Ex certification scheme that is accredited to ISO/IEC 17024 Conformity assessment – General requirements for bodies operating certification of persons.

Our qualifications are principally based on the international standards series ISO/IEC 60079: Explosive atmospheres, as well as elements of ISO/IEC 80079 for non-electrical equipment and ISO/IEC 61511 relating to functional safety for process industries.

The CompEx Scheme is operated by licensing centres which are managed by third party training companies. There are currently just under 60 licensed CompEx centres worldwide. This makes CompEx the most accessible core competency validation scheme in the world.
