NT WorkSafe Warns About Electrical Risks in Ceiling Spaces

NT WorkSafe warns about electrical risks in ceiling spaces after issuing a safety alert following an incident in which an electrician fell from a roof after suffering an electric shock in Darwin. The alert highlights hazardous conditions workers may encounter when accessing confined ceiling spaces, particularly around ageing wiring and deteriorating equipment.

NT WorkSafe Acting Executive Director Anthony Waite reminds electrical workers to always disconnect power supply before commencing work to reduce risk of electric shock. Insulation on wiring within ceiling spaces may deteriorate due to high temperatures, exposing live electrical wiring and creating additional hazards for anyone working nearby.

Why Ceiling Spaces Present Increased Electrical Hazards

Ceiling spaces often contain equipment, cabling and accessories that sit hidden from view, making visual hazard identification difficult before entry. Confined layouts, restricted movement and poor lighting compound existing hazards, raising the likelihood of electrocution, serious electric shock or burns if precautions are skipped.

Deteriorated insulation is a leading contributor to potential electrical safety risks in older properties. Over time, exposure to sustained heat can compromise protective coatings on cabling, leaving equipment and wiring more susceptible to faults.

Control Measures for Working Safely in Ceiling Spaces

“Electrical workers should always lock-out and tag-out to prevent accidental re-energisation, and always test before you touch,” said Mr Waite. This straightforward control measure remains one of the most effective ways to prevent contact with hazardous electrical equipment during maintenance or inspection work.

Before entering a ceiling space, workers should:

• Isolate power at the source and confirm de-energisation using appropriate testing equipment
• Apply lock-out and tag-out procedures to prevent accidental re-energisation
• Inspect visible wiring and equipment for signs of damaged insulation or overheating
• Use insulated tools and personal protective equipment rated for electrical work
• Follow documented safe work procedures relevant to the specific worksite

Mr Waite urged electrical workers to make safety a priority in the lead up to Christmas. "Regardless of what work you do, follow your safe work procedures, don't cut corners so you can have a safe and happy Christmas."

Supporting Health and Safety Across Electrical Trades

Maintaining workplace health standards requires more than a single safety alert — it demands consistent application of safe work procedures across every job. Businesses managing electrical teams can strengthen compliance by reviewing documented procedures such as a Working in Roof Spaces SWMS, which outlines specific control measures for confined and elevated work.

Employers should also ensure crews carry a well-stocked electrical tradies first aid kit on every job, given the risk of burns and shock injuries associated with faulty equipment or exposed wiring. Pairing this with a formal Electrical Safety Policy helps reinforce consistent practices across a workforce.

For further information on managing electrical hazards more broadly, businesses can refer to a dedicated Electrical Management Plan, which consolidates control measures, responsibilities and reporting requirements into a single reference document.

Related Electrical Safety Alerts

This alert follows a pattern of similar warnings issued by NT WorkSafe regarding electrical equipment failures. Related alerts include NT WorkSafe's warning about dangers of poorly installed DC isolators and a separate notice on electrical safety risks due to component failure in older model metre boxes.

Workers handling other hazardous materials on-site should also stay informed on separate risks, such as those detailed in coverage of fire risks associated with lithium-ion batteries.
