Electrical Safe Isolation Guide Notes

by Joe Northfield, from the Community

This electrical safe isolation guide provides step-by-step flowchart notes to ensure circuits and equipment are made safe before work begins. It covers selecting and proving a test device, identifying the correct point of isolation, switching off and withdrawing fuses, locking off MCBs, fitting warning labels, and verifying dead using a voltage indicator across phases to earth, phases to neutral, and neutral to earth. Use the notes section to record findings and site location, reinforcing safe practice and compliance.

Electrical Safe Isolation Procedure Checklist
This electrical safe isolation procedure checklist guides electricians and maintenance teams through each step required to make equipment safe before work. It covers identifying the correct point of isolation and circuit ID, selecting an appropriate isolation device based on BS7671 guidance, applying lockout tagout devices, and preventing inadvertent reinstatement. The checklist prompts verification using an approved, calibrated voltage indicator and proving unit, with photo evidence of calibration and device operation. It includes recheck steps to test before and after, securing covers, reidentifying sources, documenting actions, and formal confirmation that the system is safe to begin work. Use this template to standardize safe isolation, support compliance, and reduce risk of electric shock or unexpected energization.

Trainee Electrical Safety and Safe Isolation Assessment
This trainee assessment template is designed to evaluate competency in electrical safety and safe isolation procedures. It covers initial details such as trainee name, assessor, and location, followed by a structured checklist of core tests: volt stick checks, visual inspection, earth loop impedance (parts 1 and 2), earth continuity, insulation resistance, and verification using a two pole voltage indicator. It also includes locking off requirements and space for assessor comments. Use this template to standardize training assessments, reinforce compliance with safe isolation practices, and document trainee performance for auditing and improvement.

Essential Energy Service Mains Onsite Post Audit
This field audit checklist supports the Essential Energy Bulk Service Mains Replacement Program. It guides auditors through customer communication, switchboard cleaning and asbestos controls, equipment sealing, phase sequencing and recording, and isolation of main switches, circuit breakers, and fuses. It verifies correct termination clamps, shear-off connections, neutral bonding, drip loops, and compliance with Essential Energy construction standards and NSW Service Installation Rules. It includes checks for new mains boxes and isolation devices, removal of redundant hardware, vegetation clearing, and leaving the site safe. It also captures destructive connection testing plus no‑load and with‑load voltage and current readings across phases, neutral, and main earth.

High Risk Isolation Audit Checklist
This high risk isolation audit checklist helps teams verify hazardous energy controls and validate isolation effectiveness on complex worksites. It covers identifying energy sources, selecting proper isolation methods, testing single and multiple isolation points, and documenting TRA and permit requirements. The template supports assigning an isolation coordinator, communicating activities to nearby workers, and ensuring all tools are cleared and personnel are safe before re energising equipment. Use it to improve compliance and reduce risk during electrical, mechanical, and commissioning tasks.
