Flammable liquid fires can quickly become catastrophic events. They can result in fatalities and the devastation of businesses, the community and natural environment. To raise awareness about the importance of flammable liquids safety, we’ll be highlighting 5 real-world incidents of chemical fires. We’ll detail how these horrific accidents have occurred — and suggest 5 ways that you can help reduce the risk of fires, explosions and dangerous incidents in your own workplace.
A worker was spraying a flammable paint primer under a gas water heater to kill mould and bacteria. The worker failed to shut off the pilot light on the gas heater before spraying, and the flame ignited the paint causing a flashback. The worker was hospitalised with burns to the face, neck and upper body.
Incidences such as this can be avoided if your business develops clear work procedures for staff who are handling and storing Class 3 Flammable Liquids.
You should create clear work procedures, including pre-operational safety checks, for all tasks that involves the use of flammable liquids.
One of the most crucial safety measures that staff handling flammable liquids must be aware of, is how to correctly identify and eliminate an ignition source from their work area.
These work procedures and safety checks should include (as a minimum):
While a worker was adjusting the flow of fuel in between two strainers, pressurised oil began to leak from a boiler. Oil sprayed across the room and covered a wall — as well as the worker. The oil ignited and the worker suffered second degree burns and was hospitalised. Another worker (uninjured) was trapped at height and had to be rescued by Fire Services using a ladder. An investigation found that the equipment regularly leaked oil.
As this incident has proven, ignoring maintenance issues with your machinery and equipment can result in serious accidents when flammable liquids are involved.
Apart from regularly checking the integrity and functionality of your production equipment, you should also be checking, clearing and repairing equipment.
Develop an inspection and maintenance checklist for:
By scheduling preventative maintenance on plant and machinery, you can reduce the risk of fire, explosion and human harm.
A diesel mechanic was cleaning a metal workbench with liquid alcohol and a rag. The alcohol was sitting on the bench in a plastic container with the lid off. A torch fell off the bench and sparked. This ignited the alcohol vapours on the bench and inside the container. The worker was burned and hospitalised for 12 days — they had not received any training in chemical usage and safety.
Train your workers so they know how to use chemicals safely and understand how the materials and substances stored nearby can cause flammable liquids to burn, explode or react dangerously. Your training and induction program should include:
A worker was cleaning implements and componentry with toluene. Working in an enclosed mixing room, the worker began transferring toluene from a drum into 2 x smaller plastic containers. Next to the toluene was an (almost) empty drum of methyl isobutyl ketone. An ignition occurred near the toluene (still unsure how it happened) and a flashback travelled toward the methyl isobutyl ketone which exploded. The worker suffered burns to more than 90% of their body and died 11 days later in hospital.
This terrible accident could have been avoided if hazardous chemicals were correctly segregated.
You should always refer to Safety Data Sheets and employ proper chemical segregation in all chemical mixing, handling and storage areas.
In your own workplace, make sure that you:
A worker was carrying out some welding when a spark flew into an open jerry can of fuel. The vapours immediately ignited, and the worker was burned in the fire. They required hospitalisation.
Fuel is an extremely volatile substance with low flash point. This means that it can easily ignite at room temperature.
To avoid an incident such as the one described above, you must ensure that lids are always kept on chemical containers. If chemical containers aren’t being used, they should be immediately put away in a compliant Class 3 Flammable Liquids cabinet. The cabinet will provide a range of risk control measures for your chemicals including vapour containment, spill and leak containment and fire prevention.
In addition to keeping chemical containers closed and storing your flammable liquids correctly, your business should implement safe work procedures.
Procedures should include instructions for staff members or contractors carrying out maintenance involving hot work, to first check the area for flammable and combustible items.
It’s also important to develop and sustain good housekeeping procedures, to ensure all work areas are properly cleaned, maintained and organised.
Some good housekeeping procedures may include:
