RA-HS145 Electrical Isolation and Commissioning
| File Reference : | Risk Assessment Electrical Isolation |
This example covers electrical isolation and commissioning of cooling and refrigeration equipment - safe isolation, lock-off, arc flash and commissioning checks.
This example risk assessment has been prepared using the
F-HS20 General Risk Assessment form template - a purpose-built template designed to focus entirely on what matters: identifying hazards, rating risk and recording controls, without any unnecessary fields getting in the way.
The file is supplied in fully editable MS Word format and can be saved to Google Docs if required, with pre-defined styles throughout to match the risk ratings.

Risk Assessment - Electrical Isolation and Commissioning
This pre-completed risk assessment covers electrical isolation, testing, fault-finding and commissioning of air cooling and refrigeration equipment across domestic, commercial and industrial systems. It considers electricians, commissioning engineers, service engineers, apprentices, supervisors and anyone near opened panels or accessible live parts.
What Does This Risk Assessment Cover?
The assessment addresses the significant hazards of electrical work on cooling plant, including:
- Electric shock - contact with live conductors during isolation, testing, fault-finding and commissioning
- Unexpected re-energisation - failure to isolate all energy sources, inadequate lock-off and stored energy release
- Arc flash - switching operations, insulation testing and work on live or inadequately isolated equipment
- Commissioning errors - incorrect settings of safety devices, pressure controls, overloads and mis-wired controls
- Working environment - extended periods in plant rooms, ceiling voids, risers and roof plant enclosures
- Slips, trips and falls - trailing test leads, tools on the floor and work at height during electrical tasks
How the Risks Are Rated
Every hazard is scored twice. The inherent rating shows the risk before controls are considered, and the residual rating shows the risk that remains once the listed controls are in place - giving a clear picture of how much each set of controls is actually doing. Ratings are selected from pre-populated drop-down boxes, with document styles that colour-match each rating automatically, and recognised safety pictograms mark hazards, mandatory controls and prohibitions throughout.
Who Is This Risk Assessment For?
This assessment is suitable for any business carrying out electrical work on cooling and refrigeration plant, including:
- Air conditioning and refrigeration contractors
- Electrical and commissioning engineers
- Mechanical and electrical (M&E) contractors
- Facilities and building services providers
Ready to Adapt to Your Work
The controls reflect established good practice for safe isolation and commissioning. Review each row against your own procedures and equipment, adjust the ratings where your circumstances differ, and record your site-specific details in the completed-by and location fields.
Health and Safety Compliance
This document provides ready-to-use evidence of risk assessment and supports occupational health and safety management. The assessment is based on the F-HS20 General Risk Assessment template, is fully editable in Microsoft Word, and can be customised with your company details, site-specific information and review dates.
