A company which cleans and repairs storage tanks for the chemical industry has been convicted and fined on Wednesday after a worker died in an empty tank.
Altona North company Depot Vic Pty Limited, formerly known as Hyde Park Tank Depot Pty Ltd, pleaded guilty to failing to provide and maintain a safe workplace. It also pleaded guilty to failing to provide proper training and instructions to its employees.
The country court Judge Roy Punshon imposed a $500,000 fine on the company.
On 16 August 2007, 42-year-old Geoffrey Johnson of Werribee was cleaning the inside of a 25,000 litre tank nearly three metres high at the company’s premises. He was using a chemical to remove latex when he was overcome by chemical fumes.
He was later found dead inside the large empty tank by co-workers who tried to revive him, to no avail.
Investigations revealed that the company’s Work Method Statements, as well as its Safety Training, were inadequate.
Depot was not able to produce a Material Safety Data Sheet for the chemical used on the day of the incident. It would have indicated that the product contained methylene chloride, a chemical which may result to dizziness, impaired co-ordination and headaches for anyone using it.
WorkSafe said a concentration of 20,000 parts per million of the chemical in the tank can be “acutely lethal”. A concentration of 50,000 ppm is considered as “immediately life threatening”.
WorkSafe found several other infractions by the company, including the lack of confined space entry permits and inappropriate breathing equipment during tank cleaning.
The absence of a rehearsal of emergency procedures was also noted by WorkSafe. It was revealed that a co-worker entered the tank to rescue Mr Johnson without personal protective equipment. He had to get out after about 30 seconds because of dizziness.
The Director of WorkSafe’s Manufacturing, Logistics and Agriculture Program, Ross Pilkington, working in confined spaces are high-risk, high-consequence environments.
“With the addition of chemicals and gases into these places, those risks are magnified,” Mr Pilkington said.
“Safeguards include having, and using, systems of work which incorporate safe work procedures, appropriate atmospheric testing and personal protective equipment saves lives.
“Developing hazard identification and risk assessment systems to control access such as a ‘confined space entry permit’ is a common approach.”
