Electrician RAMS: Risk Assessments for Electrical Work
Electricians face a unique problem with RAMS. The hazards in electrical work are genuinely life-threatening — yet most generic risk assessment templates treat electrical work the same way they treat any other trade. If you're looking for an electrician risk assessment template or electrical RAMS guidance that reflects the real risks of your work, generic documents won't cut it. "Isolate before working" and "use insulated tools" aren't risk assessments. They're platitudes that tell a principal contractor nothing about how you'll actually manage the risks on their site.
This guide covers the hazards specific to electrical installation work, the standards your RAMS should reference, and the trade-specific detail that gets your documents accepted rather than bounced.
Why electrical RAMS need trade-specific detail
The principal contractor reviewing your RAMS is looking for evidence that you understand the specific hazards of your trade and have genuine procedures to manage them. For electricians, that means:
- Safe isolation procedures that reference BS 7671 and GS38 specifically
- Competence evidence — ECS card grades, 18th Edition qualification date, any specialist certifications
- Test equipment details — GS38-compliant probes, calibration dates, proving units
- Circuit-specific information — what you're working on, how it's isolated, how you'll prove dead
A risk assessment that says "electrical isolation procedures will be followed" without describing those procedures is a rejection. Principal contractors have seen it a thousand times, and it tells them nothing about whether you actually have a safe system of work.
Core electrical hazards and control measures
Electric shock and electrocution
The primary hazard. Contact with live conductors at 230V can kill — cardiac arrest from ventricular fibrillation can occur in under a second. The severity is always high. Controls reduce the likelihood, never the severity.
Your RAMS should cover:
Safe isolation procedure (the full sequence):
- Identify the circuit at the distribution board
- Switch off and isolate — remove fuse carrier or lock off MCB/RCBO
- Lock off with a personal lock-off device using a unique key (not a shared padlock)
- Prove the voltage indicator is working using a proprietary proving unit (not by testing a known live source — that creates the hazard you're trying to avoid)
- Test for dead at the point of work — all conductors tested between each other and to earth
- Prove the voltage indicator again using the proving unit
Reference: HSE Guidance Note GS38 (Electrical test equipment for use by electricians) and BS 7671:2018+A2:2022 (Requirements for Electrical Installations).
Test equipment: All voltage indicators and test probes must comply with GS38 — fused leads with retractable insulated probes, rated for the installation voltage. Proving units must be proprietary devices, not improvised live sources. Record calibration or replacement dates.
State the competence of the person carrying out isolation: "Safe isolation carried out by [name], ECS JIB Approved Electrician, 18th Edition qualified [date], safe isolation refresher [date]."
Arc flash
Less discussed than shock, but potentially devastating. A short circuit in a distribution board can produce an arc flash with temperatures exceeding 15,000°C. The risk is highest when working on or near energised equipment — particularly during inspection and testing, or when removing covers from distribution boards that may have loose connections.
Controls:
- De-energise before opening enclosures wherever possible
- When live testing is necessary (permitted only when dead testing cannot establish the required information), use insulated tools, wear appropriate arc-rated PPE, and restrict access to the area
- Ensure the upstream protective device is in service so that any fault is cleared rapidly
- BS 7671 Regulation 14 permits live working only when it is unreasonable for the conductors to be dead — document your justification
Working at height
Electricians regularly work at height: installing containment at ceiling level, wiring lighting circuits, working in ceiling voids accessed by ladders or MEWPs.
Your RAMS should specify:
- Equipment for each task: Podium steps for work under 2m platform height. MEWP (cherry picker) for higher or longer-duration tasks. Ladders only for brief access (under 15 minutes, low-risk task) per the Work at Height Regulations 2005 hierarchy.
- Competence: IPAF licence for MEWP operation. PASMA for tower scaffold assembly if used.
- Inspection: Scaffold and MEWP inspected before each use. Scaffold formally inspected at least every 7 days per the Work at Height Regulations.
Cable routes and hidden services
Drilling, chasing, and fixing into walls and floors risks striking existing services — gas, water, electrical, or data cables. On refurbishment projects, service routes are often undocumented.
Controls:
- Use a cable avoidance tool (CAT) before any penetration into walls, floors, or ceilings
- Where available, review existing installation drawings or as-built records
- Follow HSE guidance note HSG47 (Avoiding Danger from Underground Services) for any ground-level work
- Avoid safe zones (BS 7671 Appendix A) — and document that you know where they are
Fire risk during electrical work
Electrical work creates fire risk in two ways: the work itself (using heat guns, soldering, or creating sparks during cable cutting) and the installed work (incorrect connections, overloaded circuits, poor terminations).
Controls:
- Fire extinguisher (CO2 for electrical fires) within the work area
- Correct cable sizing per BS 7671 to prevent overload
- Tight terminations — torque screwdriver used to manufacturer's specified torque settings
- Visual inspection before energisation — BS 7671 Chapter 62 requires initial verification including visual inspection before any testing
- RCD protection tested and verified before circuits are put into service
Hazardous environments
Certain electrical installations involve additional hazards:
- Bathrooms — zoning requirements under BS 7671 Section 701. IP ratings (IP44 minimum zone 2, IP65 in zone 1). Supplementary bonding where required.
- Construction sites — temporary installations under BS 7671 Section 704. 110V reduced voltage for portable tools, 30mA RCD protection, robust enclosures.
- Agricultural and horticultural premises — BS 7671 Section 705. Higher earth fault loop impedance requirements, livestock protection considerations.
- Hazardous areas — explosive atmospheres (BS EN 60079 series). If you're working in ATEX-classified areas, this needs specialist assessment beyond standard RAMS.
Method statement structure for electrical work
A method statement for a domestic rewire might follow this sequence:
- Pre-start — Confirm site access, review existing EICR (if available), identify consumer unit position and meter location. Confirm with DNO if service head needs attention.
- Safe isolation — Isolate all circuits at existing consumer unit. Lock off. Prove dead at all outlets, switches, and junction boxes in the work area. Personal lock-off stays in place until work is complete.
- Strip-out — Remove existing wiring, accessories, and consumer unit in sequence. Start from final circuits back to board. Note any unexpected findings (double-fed circuits, borrowed neutrals, undocumented circuits).
- First fix cable runs — Route new cables per design. Cables in safe zones per BS 7671 Appendix A where concealed. Fixings at intervals per manufacturer's spec. Fire-stop any penetrations through walls and floors.
- Consumer unit installation — Mount new board. Connect meter tails (with DNO seal broken only by agreement). Install protective devices per circuit schedule.
- Second fix — Install all accessories, luminaires, and final connections. Verify polarity at each point.
- Initial verification — Complete BS 7671 Chapter 62 testing: visual inspection, continuity of protective conductors, insulation resistance, polarity, earth fault loop impedance, RCD operation. Record all results on BS 7671 schedule of test results.
- Commissioning and handover — Energise circuits. Verify operation. Issue Electrical Installation Certificate (EIC) for new work or Minor Works Certificate as appropriate. Brief client on consumer unit operation, RCD test procedure, and emergency isolation.
What principal contractors check in electrical RAMS
From reviewing PC feedback and rejection patterns:
- ECS card grade and expiry — the specific grade matters. Approved Electrician for installation work, Electrician for supervised work. Not just "CSCS card held."
- 18th Edition certification — BS 7671:2018+A2:2022. If your cert predates the 18th Edition, that's a flag.
- Safe isolation procedure — the full GS38 procedure written out, not just "circuits will be isolated." This is the single most common rejection point.
- Test equipment — make and model of voltage indicator, reference to GS38 compliance, calibration status.
- Circuit-specific detail — what circuits, what voltages, what distribution system (TN-S, TN-C-S, TT). Generic "240V single phase" isn't enough on commercial sites.
- COSHH — cable lubricant, PVC solvent-weld cement, fire-stop products. Get the SDS, assess the hazard, and reference it.
Domestic vs commercial electrical RAMS
Domestic work — The hazards are no less real, but the documentation is proportionate. A domestic rewire RAMS package might be 6-8 pages: risk assessment covering the core hazards above, method statement following the work sequence, safe isolation procedure, and your competence details.
Commercial work — Expect to produce more detailed documentation. The PC will want your RAMS before you're given a site induction. Method statements will be task-specific (one for containment, one for wiring, one for testing). Permits to work may be required for isolation of existing supplies. Your RAMS need to address interface with other trades — who else is working in the ceiling void, what happens when you isolate a circuit that feeds another trade's equipment.
For the broader picture on what RAMS contain and how the two documents work together, see our guides on what RAMS are in construction and the construction risk assessment template guide.
Getting electrical RAMS right
Electrical work is one of the highest-consequence trades in construction. The documents should reflect that. If your RAMS could equally describe a carpenter's work by changing the trade name, they're not specific enough.
The detail that matters: safe isolation written out in full, GS38 and BS 7671 referenced where relevant, competence stated explicitly, and control measures that describe actual procedures rather than general intentions.
TradeRAMS includes an electrical hazard library built around the real risks of installation work — safe isolation, working at height, cable routing, testing procedures, and the COSHH substances electricians actually encounter. Join the waitlist for early access.
