High Voltage Electrical Installations Risk Assessment

Product Overview

This risk assessment covers activities associated with high voltage electrical installations, including planning, isolation, switching, work near equipment, testing and close-out. It supports task planning by identifying electrical, arc flash, access, plant, cable and emergency response hazards for risk management.

Activities & Risks Covered

This assessment addresses activities and risks including:

• Review the installation, supply arrangement, energy sources, worker authorisation and access routes
• Set up site access controls, barricading and housekeeping around high voltage areas
• Isolate, lock and prove equipment de-energised while managing stored or induced voltage
• Plan and communicate switching activities, work positions and switching sequences
• Manage work on or near high voltage equipment, open enclosures and restricted work positions
• Identify and manage cables, terminations, underground services and cable-handling hazards
• Control nearby plant, lifting operations, mobile equipment and ground-penetration activities
• Manage inspection, testing, commissioning and return-to-service activities
• Prepare for electric shock, burns, arc flash, evacuation and emergency response
• Check PPE, remove residual tools and materials, control re-access and update records

Who is this for?

Suitable for contractors, workers, supervisors and businesses carrying out activities involving high voltage electrical installations.
