A Queensland employer has been fined $400,000 after a fatal explosion during work to de-rim a metal drum, with the court finding that the risk was obvious and foreseeable and that practical control measures were not complex or burdensome.
The corporate employer, which operated an Isuzu truck dealership and parts business, was sentenced in the Southport Magistrates Court on 23 May 2025 after pleading guilty to a breach of section 32 of the Work Health and Safety Act 2011 (Qld). A conviction was recorded.
What happened
The incident occurred in October 2022. A 21-year-old apprentice heavy diesel mechanic was tasked with de-rimming a used metal drum for storage. The work was performed with an electric handheld grinder in a bin room that contained an atmosphere of ignitable vapours. A spark from the grinder caused an explosion.
The worker suffered full-thickness burns to 95 per cent of the body and died from the injuries. Other workers were also affected: one suffered burns to 15 per cent of the body, another suffered burns to both hands and the tip of the nose while trying to extinguish the flames, and a fourth worker suffered psychological injuries.
What the court found
The employer was sentenced on the basis that it had failed to:
- provide adequate training and supervision for de-rimming metal drums;
- conduct a formal risk assessment of the activity;
- prepare and implement a safe work procedure explaining how the task was to be performed;
- correctly store and label flammable and combustible liquids; and
- display safety signage in areas where flammable and combustible liquids and hazardous chemicals were stored.
Magistrate Thompson found that de-rimming a metal drum in an ignitable room presented an obvious and foreseeable risk. The court also found that the steps needed to minimise the risk were simple and not burdensome.
The $400,000 fine reflected the need for general deterrence and denunciation. The employer's early guilty plea, lack of prior offending and demonstrated remorse were recognised as mitigating factors. The regulator's summary also records professional and legal costs of $1,500 and court costs of $101.40, with 28 days allowed to pay. These costs are separate from the fine.
The court noted that the employer had since overhauled its safety practices. However, those measures were not treated as mitigation because they could have been implemented before the incident.
Why this matters to business managers
The matter illustrates that a task does not need to be routine, complicated or obviously industrial to require structured risk control. A seemingly straightforward activity—altering a drum for storage—created a serious ignition risk because the work method, location and surrounding substances were not adequately assessed together.
It also demonstrates the difference between having general safety expectations and controlling a specific high-risk task. Training, supervision, chemical storage, signage, formal risk assessment and a documented procedure need to work as a connected system.
Managers should be cautious about relying on worker experience, informal instructions or assumptions that a task is safe because it has been done before. Where a task involves sparks, heat, pressure, combustible materials, flammable liquids or potentially contaminated containers, the work should be assessed before it starts and stopped if the controls are not in place.
What managers should take note of
Use this matter as a prompt to review tasks involving drums, tanks, containers, grinding, cutting, welding, hot work and stored chemicals.
- Assess the task and the location together. Identify what the container may contain, what vapours may be present and whether an ignition source can enter the area.
- Set an approval process for higher-risk work. Require a competent person to confirm the method, location, isolation and controls before work begins.
- Use task-specific procedures. A generic workshop safety policy may not explain how to de-rim, cut, clean, purge or otherwise modify a container safely.
- Verify competency, not just attendance. Confirm that workers understand the hazards, equipment limits, emergency arrangements and stop-work requirements.
- Provide active supervision. Apprentices, new workers and workers undertaking unfamiliar tasks may require closer supervision and clearer escalation points.
- Control flammable and combustible substances. Check storage, labelling, segregation, quantities, ventilation and access arrangements.
- Make hazards visible. Use signage and physical controls to identify chemical and ignition risks in relevant areas.
- Review controls after changes. A change in the container, work location, tool, chemical or intended use can change the risk profile.
- Test the system in practice. Speak with workers, observe the task and check whether procedures are being followed—not merely filed.
These are general safety management lessons, not legal advice. Businesses should obtain advice relevant to their operations and jurisdiction where required.
