WorkSafe investigates Chelsea gas blast

WorkSafe says the gas explosion at Chelsea Heights on 22 October 2009 was a warning to people using acetylene to ensure it was stored safely.

In the second major acetylene explosion this year, an apprentice escaped injury after activating a van's electrical system using a remote control.  A gas leak or a fault with an acetylene tank is thought to have filled the vehicle with gas which was ignited by its electrical system.

The Director of WorkSafe's Dangerous Goods Division, Trevor Martin, said because acetylene was heavier than air and settled to the lowest point, good ventilation and storage was essential.  "Thousands of tradespeople in Victoria use acetylene everyday, but unlike most other people, they take their work home or around with them.  The  incident shows the devastating power of an explosion and the potential impact on surrounding areas. It is exceptionally fortunate that no one was seriously hurt."

On 7 July an apprentice at Echuca suffered severe burns after an acetylene leak led to an explosion under the Bridge Hotel.  While serious incidents like these are rare, when they happen the consequences are instant and have enormous impact. In both cases these young workers are lucky to be alive. Incidents like these can be prevented by removing sources of ignition, maintenance of equipment and appropriate storage of gas bottles and appropriate training.

Mr Martin said there had been a high number of serious incidents during October leading to four deaths with another five incidents which could have resulted in fatalities.  Twenty-two people have died in Victorian Workplaces this year compared with 17 at the same time last year.  This recent incident comes days before Work Safe Week (26 to 31 October) which features more than 100 events and activities across the state.
