NT WorkSafe Issues Safety Warning After Lithium-Ion Battery Explodes

Northern Territory WorkSafe has issued a safety alert after a lithium-ion battery exploded when it was left inside a vehicle. This incident highlights the fire risk these batteries pose when stored incorrectly, even for short periods.

The safety agency said the owner of the vehicle left a cordless impact wrench with the battery attached on the back seat when it exploded.

What Caused the Explosion?

NT WorkSafe's technical services director Anthony Waite said the incident serves as a timely reminder for everyone about the potential dangers lithium-ion batteries pose if they are not stored correctly.

"Lithium-ion batteries are classified as a dangerous goods item, under the Australian Dangerous Goods Code," Mr Waite said.

"This means there are specific requirements to package, store and transport these types of batteries and the devices and equipment they are found in due to potential dangers the batteries pose."

Heat and Sunlight Increase Explosion Risk

"The main message we have is not to leave or store lithium-ion batteries in hot areas or in direct sunlight, as they can explode and cause a fire risk in your business or home," Mr Waite explained.

Excessive heat exposure remains a leading cause behind battery-related fire incidents across Australian workplaces and homes alike, making vehicle interiors a particularly high-risk storage location during warmer months.

"Fortunately, in this incident, the vehicle was unoccupied, and no one was injured," Mr Waite said.

Reducing Fire and Health Risks From Battery Storage

Businesses handling lithium-ion batteries should consider practical steps to minimise both fire and health risks associated with improper storage or handling, including:

• Avoiding storage in direct sunlight or hot vehicle interiors
• Following manufacturer guidance for storing battery-powered devices
• Inspecting batteries regularly for damage or swelling
• Keeping batteries away from flammable materials to limit fire spread

For further guidance on managing these hazards, our NT WorkSafe lithium-ion battery safety guidance during Electrical Safety Week outlines additional precautions relevant to workplaces and households.

Supporting Documentation for Battery Safety

Organisations seeking to strengthen their battery handling procedures can refer to our Battery Safety SOP template, designed to help businesses document safe storage, charging, and disposal practices.

Given that lithium-ion batteries often power electrical tools and equipment, pairing battery safety measures with a broader Electrical Safety Policy helps ensure comprehensive protection against electrical and fire hazards on site.

Businesses operating in New Zealand may also find value in our Electrical Safety Checklist for NZ workplaces, which supports routine inspection of electrical equipment and devices.
