Hazardous Area Installations
We provide professional DSEAR & ATEX hazardous area site compliance and hazardous area installation services.

Hazardous Area Installation Services
F.E.S. (EX) delivers hazardous area electrical and instrumentation installation services for industrial clients in any sector where potentially explosive atmospheres may be present.
As a NICEIC Hazardous Area Approved Contractor, we carry out hazardous area installations to high standards using competent personnel. Our core capability is the safe, compliant delivery of in-house E&I construction projects in DSEAR and ATEX classified environments.
NICEIC Accreditation
Being a NICEIC Hazardous Area Approved Contractor confirms our commitment to quality within electrical construction.
This certification confirms our installations meet BS 7671. Regular audits across hazardous and non-hazardous environments help us deliver safe, compliant, dependable projects.

Installation Solutions
We help clients deliver installations that suit the hazardous area, the equipment certification and the intended process application.
- Electrical and instrumentation construction in hazardous areas
- Small plant upgrades, modifications and remedial works
- Large-scale E&I installation packages for new process areas, plant expansions and capital projects
Our experience is built around working safely in environments where explosive gases, vapours and combustible dusts must be carefully controlled, including work on intrinsically safe systems.
We understand the importance of correct equipment selection, installation methods, cable management, Ex glanding, earthing and bonding, segregation, inspection readiness and traceable handover documentation when helping clients achieve and maintain DSEAR and ATEX compliance.

Electrical and Instrumentation Installation
Typical electrical and instrumentation installation activities include electrical and instrumentation construction works for hazardous area projects, including new installations, plant extensions, process area upgrades and capital project packages.
- Electrical installation of Ex-rated equipment, including lighting, emergency lighting, small power, isolators, control stations, junction boxes, panels and associated field equipment
- Instrumentation installation for process measurement and control, including transmitters, sensors, switches, analysers, valves, actuators and associated instrument supports
- Installation of cable containment and support systems, including tray, ladder rack, conduit, Unistrut, brackets and equipment support arrangements
- Power, control, signal and instrumentation cabling, including routing, pulling, dressing, identification, segregation and mechanical protection
- Ex glanding, termination, earthing and bonding of electrical and instrumentation circuits in line with hazardous area requirements
- Installation of intrinsically safe systems, including IS cabling, barriers, isolators, marshalling panels, junction boxes and associated control system interfaces
- Modification and upgrade works to existing hazardous area installations, including additional equipment, instrument loop changes, replacement of obsolete assets and process improvement works
- Shutdown, outage and brownfield installation support where hazardous area works need to be delivered safely around operational plant constraints
- Inspection-driven remedial works, Ex defect rectification, close-out of non-conformances and preparation of installations for hazardous area inspection and verification
- Loop checking support, point-to-point testing, pre-commissioning checks, functional testing assistance and handover documentation support
- Site supervision, installation coordination, quality checks, site walk downs and project delivery support by hazardous area competent electrical and instrumentation personnel
Hazardous Area E&I Construction Projects
From modifications to major construction F.E.S. (EX) supports hazardous area projects of varying size and complexity, from a single Ex equipment replacement or instrument loop modification through to multidisciplinary electrical and instrumentation construction works across operational process plant.
Whether the requirement is a small upgrade, shutdown modification, inspection defect close-out, process improvement project or a larger construction package, our teams provide the project delivery experience needed to complete the work safely and correctly.
We work with clients from planning through to handover, helping define the installation scope, review site conditions, coordinate materials, manage site labour, supervise installation activity, prepare for inspection and support final documentation.
This practical project approach helps ensure each installation is controlled, compliant and suitable for continued safe operation in an explosive atmosphere.
