Safety warning after Queensland worker suffers burn injuries in chemical blast

Safety warning after Queensland worker suffers burn injuries in chemical blast

WorkSafe Queensland has issued a safety alert after a worker suffered multiple burns in an explosion at a marine maintenance facility. This incident highlights the hazardous nature of combining chemical solvents with heat-generating equipment in enclosed workspaces.

WorkSafe Queensland reported the worker was performing fibreglass repair work inside the hull of a boat using acetone, a highly flammable chemical, when a nearby heat gun ignited vapours generated by the solvent, causing an explosion.

What Happened During the Incident

The November 2021 incident remains under investigation, according to WorkSafe. Details released so far indicate the worker suffered burn injuries requiring hospital treatment following the blast.

WorkSafe stated that workers and others may suffer serious injury or even die as a result of fire and explosion incidents, with property damage also a likely outcome in these scenarios. Given the hazardous conditions present in many marine and industrial workplaces, employers must remain vigilant about chemical handling procedures near any plant or equipment capable of generating heat.

Understanding the Fire Triangle Risk

According to WorkSafe, real danger exists when fuel (a flammable or combustible substance), oxygen (usually present in the air) and an ignition source (energy sufficient to trigger combustion) come together — commonly referred to as the fire triangle.

This risk becomes significant whenever solvent vapours accumulate in confined spaces near powered plant equipment. Heat guns, welding tools and other plant items generating sufficient energy can ignite airborne vapours within seconds, leaving little time for emergency response.

Control Measures to Reduce Explosion Risk

For possible control measures to prevent similar incidents, visit the WorkSafe Queensland website. Employers should also consult resources from the Safe Work Australia to understand broader obligations around hazardous chemical management.

Key risk reduction strategies include:

• Eliminating heat-generating plant from areas where flammable solvents are in use
• Improving ventilation to disperse vapours before they reach ignition thresholds
• Training workers to recognise fire triangle risk factors before starting hazardous tasks
• Establishing clear emergency procedures for chemical-related fire incidents
• Reviewing plant maintenance schedules to ensure equipment doesn't become an unexpected ignition source

Protecting Worker Health and Safety

Maintaining strong health and safety practices around chemical use isn't optional — it's a legal and moral obligation. Employers running facilities with plant machinery near flammable substances should reassess emergency response plans regularly and ensure staff understand health risks tied to solvent exposure.

For related guidance, see our coverage of a NSW Resources Regulator safety alert after a worker suffered burn injuries during hot work, and an earlier safety warning issued after an SA mine worker sustained serious injuries. Businesses managing similar plant risk should also review our safety alert issued after an NT worker suffered serious crush injuries for further context on workplace incident prevention.

Supporting Documentation for Chemical Safety

Businesses handling flammable substances or operating plant near chemical storage areas should implement documented procedures addressing these risks. SafetyDocs offers a Chemical Safety SOP template designed to help organisations formalise safe handling practices.

Additional resources include our Chemical Management Plan, which supports businesses in building comprehensive frameworks for hazardous substance control. Facilities using electrical plant near flammable vapours may also benefit from our Electrical Safety Policy and Electrical Safety Checklist templates.

Organisations seeking broader digital solutions for incident tracking and compliance management can explore our range of safety software options tailored toward reducing workplace risk across construction, manufacturing and marine sectors.
