Bison - electrical excellence in hazardous ATEX conditions

Bison Electrical Services specialise in industrial installations, inspections, and maintenance - including hazardous area installations (ATEX), also known as Ex. Our experience covers hazardous areas where potentially explosive flammable gases, mists or dusts may be present.

Our ATEX (also known as Ex) installation services

ATEX is derived from the words ‘Atmospheres Explosibles’ and is part of the European equipment directive known as ATEX 201-34 EU. ATEX standards are put into practice under EN 60079-14 2014 for equipment selection and EN60079-17 2014 for installation and inspection of equipment in ATEX rated zones.

Our engineers are all CompEx trained, and have many years’ industrial electrical experience working in hazardous areas and potentially explosive atmospheres that are caused by combustible dusts, gases, vapours, or flammable gasses. They also hold the relevant electrical installation qualifications, including 18th edition IEE wiring regulations, NVQ level 3 Electrical installation & ECS etc. Rest assured, before commencing any work, we will carry out the necessary risk assessments to ensure both your safety and ours.

We are available for all DSEAR and ATEX hazardous area compliance and installation services, covering testing, inspections, installation, and maintenance of installations in hazardous areas.

Some of the hazardous area services we offer include but are not limited to;

  • Hazardous area electrical design, installation, and commissioning
  • Hazardous area Control Panel design, build and installation
  • Hazardous area inspection and testing
  • Biogas installations
  • Instrumentation and automation
  • Hazardous area test and inspection (BS60079-17)

Reactive Service – ATEX/Ex Inspection, Repairs and Maintenance Services
Bison offer a reactive service for all your electrical hazardous area needs. From inspection on leads, to fault finding on your assets, we’ll be with you quickly to put it right.

ATEX/Ex inspections are graded in three ways: Visual, Close or Detailed. To maintain the necessary ATEX protection, EN60079-17 2014 states that all ATEX installations must be inspected regularly.

Within 18 months of installation, a minimum Visual inspection must be carried out and remedial work completed. Following this, after 18 months a Close inspection is necessary, and a further Detailed inspection no later than 4½ years after the initial installation.
The frequency of inspections may increase, depending on a site’s environment and specific equipment installed.
