Electrical RAMS Example UK

Typical Contents of an Electrical RAMS

Scope of works

The specific electrical task: first fix wiring, second fix, consumer unit installation, testing and commissioning, switchgear, containment, or maintenance. The scope must name the building, floor, or area. A generic “electrical installation” scope is insufficient.

Safe isolation and lock-off

The safe isolation procedure for this specific job: which circuit or distribution board is isolated, who carries out the isolation, how the circuit is proved dead (two-pole voltage tester), and how the isolation point is secured (lock-off device and personal danger tag).

Proving dead procedure

Reference to HSE Guidance Note GS38 safe isolation. Voltage tester check list: test tester, test circuit, test tester again. No work to begin until the circuit is confirmed dead and secured.

Hazard register

Key hazards: contact with live conductors, arc flash risk, manual handling of heavy containment, working at height for containment installation, COSHH for cable jointing compounds and solvents.

Plant and equipment

Power tools, cable drum trailers, access equipment (towers, podium steps), and testing equipment. PUWER inspection references and operator competence (JIB, ECS card).

Testing and commissioning sequence

Insulation resistance testing, continuity, polarity checks, earth fault loop impedance, RCD testing. Live tests carried out only by competent persons with appropriate PPE (insulated tools, arc flash PPE where required).

Common Electrical Hazards and Controls

• Contact with live conductors — Safe isolation, lock-off, prove dead, GS38 test equipment
• Concealed cables and services — CAT/Genny scan, plans, no drilling without confirming cable-free zone
• Working at height — Podium steps, tower scaffold, no standing on tools or boxes
• Manual handling of heavy equipment — Cable drum handling, distribution board installation, mechanical aids
• Silica dust from drilling — Wet drilling, local exhaust ventilation, RPE for extended periods
