For pharmaceutical, life sciences and laboratory engineering teams
ATEX Electrical Services for Pharmaceutical & Life Sciences Sites in Scotland
Plan hazardous-area electrical installation, inspection, maintenance and equipment work around solvent handling, production and laboratory operations. WB Electrical supports defined gas and vapour Zone 1 and Zone 2 work with relevant CompEx competence and traceable records.
From Larkhall, we support suitable pharmaceutical, life sciences and laboratory sites across Scotland, subject to scope, programme, site controls and the hazardous-area information available.
Defined Ex scope. Controlled change. Traceable handover.
Solvents, controlled change and operational continuity
Start with the controls around your pharmaceutical site
A solvent-handling change, inspection finding and equipment upgrade need different responses. Start with the exact process, hazardous-area information and site change-control requirements so the electrical task fits the operation rather than treating the whole facility as one Ex environment.
Protect production, laboratories and controlled work areas
Production, laboratory, engineering and maintenance teams may share strict access, gowning or material-control arrangements. Define the electrical scope early so permits, isolations, access conditions and handback are agreed before work starts.
Work from the confirmed hazardous area and substance information
Only the site’s confirmed classification identifies where special hazardous-area controls apply. Solvent transfer, dosing, filling, cleaning or laboratory activities may create vapour hazards where the assessment identifies them, so the agreed task must use current zone, substance and operating information with relevant gas or vapour competence.
Keep equipment changes and electrical records traceable
Equipment changes, inspection findings and replacements can leave drawings, asset references and Ex records drifting apart. Keep the change, equipment reference, completed work and outstanding actions connected so engineering and quality teams can trace what changed.
Choose the route closest to the pharmaceutical electrical task
Match the CompEx service to the pharmaceutical requirement
The requirement may start with a solvent-area alteration, inspection defect, new equipment or failed Ex item. Each service keeps its own purpose, competence and records so installation, inspection, maintenance and documentation are not blurred together.
New circuits, alterations and process or laboratory interfaces
New circuits, containment, cable routes, lighting, power and control interfaces around identified gas or vapour hazardous areas within suitable pharmaceutical production, solvent handling, laboratory or supporting process areas.
Use this route when the job is broader than one Ex item. The issued classification, process information, equipment requirements and site controls shape the installation and initial checks.
Existing Ex assets and inspection findings
Existing Ex electrical assets that need a defined visual, close or detailed inspection scope, including equipment serving solvent handling, filling, laboratories, production skids or controlled process areas.
Inspection planning should consider the equipment population, records, process state, access and isolation needs. Findings should remain traceable to the asset and room or process location inspected.
Planned upkeep and controlled fault response
Recurring maintenance, inspection-led defects and electrical faults within an agreed hazardous-area support arrangement for operational pharmaceutical and life sciences sites.
Planned visits help keep equipment serviceable and close known defects. Reactive work still needs suitable competence, permits, isolation, access approval and a controlled response route rather than an assumed emergency attendance promise.
Ex equipment installation and replacement
Defined Ex enclosures, isolators, junction boxes, lighting, glands, entries and other electrical equipment serving hazardous-area production, laboratory or process systems that needs installing or replacing.
The proposed item must suit the confirmed location and duty. A familiar or apparently like-for-like product still needs its marking, certification, accessories and installation interface checked before use.
Planning input and documentation close-out
For projects that need earlier contractor input, hazardous-area electrical planning and design support can help turn issued hazardous-area information, process or laboratory interfaces and equipment requirements into a buildable electrical scope.
For inspection records, asset references, defect schedules and remedial evidence, use hazardous-area electrical documentation and reporting. The electrical records can support engineering and quality records but do not replace DSEAR assessment, hazardous-area classification, pharmaceutical validation, cleanroom qualification or client quality responsibilities.
Engineering, operations, quality and contractors working to one controlled plan
Coordinate the work around permits, change control and controlled areas
Hazardous-area work needs a clear safe system of work. Confirm the process state, affected equipment, isolation authority, permit route, atmospheric-testing requirements, change-control reference, controlled-area requirements and the people responsible for handback.
01
Define the process, room and equipment interfaces
Review the hazardous-area drawing or confirmed zone, solvent or vapour details, equipment tags, findings and work location. Identify relevant interfaces with transfer systems, mixers, filling lines, process skids, laboratory equipment, controls, instrumentation and ventilation.
02
Coordinate permits, isolation and site quality controls
Agree induction, permits, access, electrical, mechanical and process isolations, plus atmospheric testing where required. Coordinate other contractors, controlled-area entry and any gowning, cleanliness or change-control requirements.
03
Agree the work window, verification and handback
Set a realistic sequence around production, laboratory activity, cleaning cycles or shutdowns. Include isolation, completion checks, authorised handback, electrical records and any required client engineering or quality review.
If the classification, solvent or process information, change-control route or safe working arrangements are unclear, resolve the gap before hazardous-area work starts. Programme pressure is not a reason to bypass the site’s controls.
Planning a pharmaceutical shutdown, alteration or inspection programme? Discuss the hazardous-area electrical scope.
Asset references, change records and electrical close-out
Leave the Ex work usable for engineering and quality teams
Agree the site’s tag references, report format, document references, recipients and any applicable change-control identifier before work starts. The handover should make clear what was inspected, installed, maintained or replaced, where it sits in the room or process and what remains outstanding.
For each hazardous-area task
- Site, building, room or process area, hazardous-area location and asset or equipment reference.
- Applicable inspection, installation, maintenance, equipment or electrical test records.
- Completed work, open defects, limitations and actions remaining.
- Important concerns raised with the nominated engineering, EHS, quality or close-out owner as agreed.
Across pharmaceutical and life sciences sites
Keep the room or process location, equipment reference, scope completed, applicable inspection or test information, product references and defect status connected. Photographs or remedial evidence can be included where they genuinely help the site record and site rules allow them.
Across solvent handling, production and laboratories, use the client naming and document-control system while retaining the actual classification and responsibilities. Where a regulated quality system applies, align electrical handover references with the client process as instructed.
For a records-led close-out or an Ex file that has become fragmented, Hazardous Area Electrical Documentation & Reporting can organise the electrical evidence and outstanding actions.
Hazardous-area competence plus controlled-site contractor discipline
A contractor that can fit into quality-managed operations
WB Electrical hazardous-area and controlled-site electrical work.
WB Electrical
Pharmaceutical electrical work may sit inside strict induction, permit, access, cleanliness, documentation and change-control systems. The electrical scope still needs to remain clear and traceable.
WB combines commercial and industrial contracting with relevant CompEx gas and vapour competence. Individual competence, site information and controlled-area rules still have to match the task.
Supplier assurance
Review WB’s current accreditations and certificates. Tell us about your contractor approval requirements, relevant CompEx competence, insurance evidence, risk assessments, method statements, induction, permit arrangements, change-control expectations and controlled-area rules so the supporting information matches the site and task.
Before you arrange hazardous-area electrical work
Pharmaceutical and life sciences ATEX electrical questions
Can hazardous-area electrical work be planned around pharmaceutical operations?
Suitable work can often be phased, but some tasks need isolation, shutdown or laboratory downtime. The programme follows production, permit, access and change-control requirements rather than assuming the area can remain available.
Can WB Electrical decide which areas are Zone 0, Zone 1 or Zone 2?
No. The operator or appointed competent specialist should provide or confirm the hazardous-area classification. WB uses the issued information to plan the agreed electrical work and does not present routine contracting support as the site’s DSEAR assessment or formal zoning exercise.
What information helps you quote hazardous-area work at a pharmaceutical site?
Send the exact room or process location, hazardous-area drawing or confirmed zone, solvent/vapour details, equipment tags, relevant findings, required outcome, timescale and known permit, isolation, access, change-control or shutdown constraints.
How does WB fit with GMP, change control and validation requirements?
WB can follow the site’s permit, engineering and quality change-control arrangements and provide the electrical records generated by the agreed work. WB does not perform pharmaceutical process validation, cleanroom qualification, batch release or replace the responsibilities of the client’s QA, validation or production teams.
Do you currently undertake combustible-dust hazardous-area work?
No. WB’s current marketed CompEx scope is gas and vapour work. Pharmaceutical powder handling and some other processes can involve combustible-dust hazards, but dust-specific hazardous-area work is not included in the current offer. Use the site’s confirmed classification so the requirement can be routed correctly.
For the wider hazardous-area service family, see CompEx Services. If the requirement is ordinary electrical work outside the classified area, use the relevant Industrial & Manufacturing Electrical Services route rather than forcing it into the Ex scope.
One task, a shutdown package or ongoing hazardous-area support
Discuss your pharmaceutical ATEX requirement
Tell us what prompted the requirement, where it sits in the pharmaceutical or laboratory process and what hazardous-area information is available. WB can identify whether the next step is records review, site walk, quotation or coordination with another specialist.
Useful information for your enquiry
- Company, site postcode, room or process area and engineering, maintenance, EHS or quality contact as appropriate.
- Hazardous-area drawing or confirmed zone information and relevant solvent, gas or vapour details.
- Equipment tags, process or laboratory interfaces, inspection findings, drawings, photographs where permitted or certificate references, if available.
- Operating pattern, production or laboratory constraints, maintenance or shutdown dates, required outcome and timescale.
- Permit, electrical/mechanical/process isolation, atmospheric testing, controlled-area access, gowning or cleanliness rules, change-control and handback requirements where applicable.
You can enquire before every detail is known. Useful starting information includes the room or process area, current zone/drawing, solvent or vapour information, equipment references, inspection records, required outcome, programme and permit, access, isolation or change-control constraints.
What affects the quotation?
Scope, asset quantities, equipment, controlled-area access, isolation complexity, operating restrictions, working hours and visit count affect cost. Gowning, change-control steps, production sequencing, specialist access and incomplete records can also shape the quotation.
Confirm the included electrical work, inspection or test requirements, records, exclusions and VAT before booking. Additional remedials, formal DSEAR/classification work, pharmaceutical validation or qualification, process engineering, product supply or return visits are separate unless expressly included.
For a broader hazardous-area requirement, review the CompEx Services hub or use the same business quotation route with the site, scope and timescale.
