CompEx Electrical Services for Pharmaceutical & Life Sciences Production
Electrical works for solvent handling, processing, and production areas where hazardous atmospheres may exist. CompEx installations and alterations in ATEX zones, Ex inspection and maintenance, intrinsically safe circuits, Ex lighting and controls, plus audit ready documentation to support DSEAR compliance. DSEAR places duties on employers to assess and control risks of fire and explosion from dangerous substances
Hazardous area installations and alterations in ATEX zones
CompEx installations and modifications in zoned areas, with correct equipment selection, glands, terminations and practical isolation for maintenance. HSE sets out how areas are classified into zones, based on likelihood and persistence.
Solvent handling areas, filling lines, and production interfaces
Electrical works around solvent handling, transfer, dosing, filling, and associated plant interfaces, delivered with controlled methods and clean, maintainable routing. HSE notes explosive atmospheres can be caused by flammable gases, mists or vapours, and an ignition source can trigger an explosion.
Dust risk areas, powder handling, and contained process equipment
Support where combustible dust may be present, for example powder handling, milling, sieving, transfer points, or contained equipment interfaces. HSE provides definitions for dust Zones 20, 21 and 22.
Intrinsically safe circuits for instrumentation and control
Intrinsically safe (Ex i) circuits for instrumentation and control signals, with correct segregation, labelling and documentation, so future maintenance is straightforward and low risk.
Earthing and bonding checks, including static risk focus
Bonding continuity checks and improvements in zoned areas, plus practical reporting for ongoing inspection and maintenance. This matters where static control and continuity are part of the site’s ignition source controls.
Ex inspection, verification, and remedial programmes
Structured Ex inspections, tagging, defect reporting and prioritised remedials. Inspection and maintenance of electrical installations in explosive atmospheres is covered by BS EN IEC 60079-17.
Pharmaceutical and life sciences production
Hazardous area electrical work that supports safety, uptime, and audit readiness
Pharmaceutical and life sciences sites can include solvent use, vapour risks, and in some processes, combustible dust. In those environments, the electrical installation needs to be right first time, then kept right through inspection, maintenance and clear records.
DSEAR is the UK framework that requires employers to assess and control risks of fires and explosions caused by dangerous substances in the workplace. HSE also explains that explosive atmospheres can be caused by flammable gases, mists or vapours, or by combustible dusts, and that ignition sources must be controlled.
WB Electrical provides CompEx certified support across Scotland, from installation and alteration through to inspection, remedials and compliance reporting.

Solvent risk, dust risk, and zero surprise shutdowns
Common pharmaceutical and life sciences hazardous area triggers
- New kit, line changes, or process upgrades where area classification and equipment suitability need rechecked
- Solvent handling, storage, dosing, filling, and extraction areas where vapour risk drives zoning and ignition control
- Powder handling points where combustible dust risk is present, and dust zones may apply
- Ageing Ex equipment, damaged seals, incorrect glands, compromised enclosures, or poor maintainability
- Missing tags, unclear identification, incomplete inspection records, weak traceability for dutyholders
- Inspection findings needing remedials before sign off, restart, or audit, inspection and maintenance practice sits under 60079-17
- Earthing and bonding concerns, static controls, or poor continuity at metallic interfaces
- Short shutdown windows, work needs planned and delivered cleanly, first time
If any of these are familiar, we can survey the area, agree a practical scope, then deliver with controlled downtime and clear reporting that supports your compliance trail.
