Road tanker manufacturing company fined after gas asphyxiation

A leading tanker manufacturing company has been fined £200,000 after a worker collapsed from gas exposure before the same fate befell a colleague who went to check on him.

On 18 March 2020, a worker at Tasca Tankers in Wakefield, West Yorkshire entered a metal tank to carry out some welding work. A few minutes later, a second worker looked inside the tank to check on his colleague and found him slumped at the bottom. After shouting for help the second worker went into the tank and also collapsed. Emergency services rescued both employees after entering the space with breathing apparatus.

An investigation by the Health and Safety Executive (HSE) found  the company had failed to ensure safety of their employees while working in the tanks, classified as a confined space. When inside the tank, the employees suffered asphyxiation resulting from inhalation of argon gas leaking from the welding torch.
