Recognizing and Avoiding Energized Panels

Electrocution
English (NZ)

The Problem

Energised panels are a hidden hazard on many worksites. Workers who come into contact with live electrical panels risk severe injury or even death due to electric shock, arc flash, or burns. Electrical incidents contribute to numerous workplace injuries each year. Today, we’ll discuss how to recognise energised panels, understand the risks, and take steps to prevent accidents.

Identify the Hazards

Energised Panels:

  • May appear safe but can contain live circuits or components.
  • Often have no visible signs that they are live, increasing the risk of accidental contact.

Common Risks:

  • Contact with exposed live wiring.
  • Accidental activation of circuits during maintenance.
  • Incomplete or improper isolation of electrical systems.

Consequences:

  • Electric shock, burns, or fatality.
  • Arc flash events resulting in severe injuries or fire.

Safety Practices and Preventative Measures

Recognise Energised Panels:

  • Look for warning signs, labels, or tags indicating a panel is live.
  • Always assume a panel is energised unless confirmed otherwise by a qualified person.

Use Proper Tools and PPE:

  • Wear insulated gloves and boots when working near panels.
  • Use a voltage tester or meter to confirm whether a panel is live.
  • Ensure tools are insulated and rated for electrical work.

Follow Lockout/Tagout (LOTO) Procedures:

  • De-energise the panel before carrying out any work.
  • Use lockout devices and tags to prevent accidental re-energisation.
  • Confirm isolation of all energy sources before starting work.

Maintain Safe Distance:

  • Stay at least one metre away from energised panels unless you are trained and authorised.
  • Clearly mark and restrict access to areas around live panels.

Report Defective Panels:

  • Report any exposed wires, damaged components, missing covers, or unusual sounds to your supervisor immediately.
  • Do not attempt repairs unless you are a registered electrician.

Real-Life Case or Scenario

Where possible, use an actual incident that you have experienced or been involved in.

A worker touched an energised panel while inspecting equipment. The panel had no warning label, and the worker was not wearing appropriate PPE. The result was severe burns and hospitalisation. A quick voltage check and proper PPE would have prevented this injury.

Employee Responsibilities

  • Checking panels for hazard labels and signs of damage.

  • Wearing the correct PPE and using tools designed for electrical work.

  • Following LOTO procedures when working on or near electrical systems.

  • Reporting damaged or faulty panels immediately.

Employer Responsibilities

  • Provide training on identifying and working safely around energised panels.

  • Label and maintain all electrical panels in accordance with WorkSafe NZ requirements.

  • Supply insulated tools and PPE suitable for electrical work.

  • Enforce lockout/tagout procedures and ensure workers are trained and competent.

Discussion & Questions

  • “What signs do you look for to determine if a panel is energised?”
  • “Has anyone seen or experienced an incident involving a live panel? How was it handled?”‍

Encourage employees to share their experiences, observations, or concerns.

Commitment/Action Plan

Let’s commit to inspecting all panels before beginning work, using the right PPE, and strictly following lockout/tagout procedures. Starting today, treat all panels as energised until tested and confirmed otherwise. Make electrical safety your priority.

Wrap-Up

Energised panels are a serious hazard, but with awareness and proper procedures, accidents can be prevented. Always use the correct PPE, inspect equipment, and isolate power before working. Thank you for your attention and commitment to safety.

Standards Overview

Under the Health and Safety at Work Act 2015 (HSWA), PCBUs (Persons Conducting a Business or Undertaking) must ensure that risks from electrical equipment are eliminated or minimised. WorkSafe NZ requires:

  • Clear procedures for identifying and working around live electrical systems
  • The use of isolation and lockout/tagout systems during servicing and repairs
  • The provision and use of electrical PPE and insulated tools
  • Only qualified persons to access or work on energised panels
