Risk Assessment for Electrical Switchgear Work — UK

UK construction-safety guidance by the Riskora Editorial Team

For electrical switchgear work, the difference between a passing safety review and a failing one usually comes down to how specific the documentation actually is. Arc flash incidents release energy comparable to a small explosion and can occur on any energised equipment, even when no direct contact is made. The legal position for electrical switchgear work is well established. The Electricity at Work Regulations 1989 and HSE guidance require arc flash risk assessments for all switchgear work. A well-written Risk Assessment converts the legal duty into something workers, supervisors and clients can actually use on the day.

  • Competency requirements and training records
  • Communication and briefing procedures
  • Supervision and monitoring arrangements

Common Mistakes to Avoid

  • Using a generic template without adapting it to the specific work on or near electrical switchgear, distribution boards, and panel boards conditions
  • Not reviewing the document when site conditions change
  • Missing sign-off from a competent person before work begins
  • Failing to consider arc flash producing extreme heat and blast pressure
  • Not addressing electric shock from inadvertent contact with live busbars

Example Scenario

Based in Plymouth, a facilities manager has a Friday deadline for a Risk Assessment and is working evenings to get it through review — the kind of pressure most small contractors will recognise. Using Riskora, they pick the relevant trade preset, drop in the project address, refine the pre-loaded hazards for electrical switchgear work, and export a clean PDF ready for sign-off the same afternoon. The finished document explicitly addresses arc flash producing extreme heat and blast pressure, which the principal contractor would otherwise expect to see written into the pack.
