A worker was killed and another seriously injured during leak testing on a heat exchanger.
The workers were using inert gas when a tube bundle ejected with great force striking them both.
An investigation into the cause of the incident found the following immediate causes:
1. Use of an unsafe work procedure for leak testing of the heat exchanger, no test ring was used and the use of high risk pneumatic test method.
2. Failure to stop test when instructed.
3. Inadequate protection from the potential of tube bundle propelling outwards.
