At the beginning of this month, an explosion and fire caused the death of four workers, as well as serious injury to a fifth person, at the Chevron Pembroke Refinery during tank cleaning operations.
Hazardous Installations Directorate’s head of operations, Ron De Cort, has now released a reminder to all companies working in the field about the dangers of tank cleaning.
The memo urges workers to reacquaint themselves with the risks associated with tank cleaning and the established control measures. To do so, it recommends reading:
· Safe maintenance, repair and cleaning procedures, Dangerous Substances and Explosive Atmospheres Regulations 2002. Approved Code of Practice and Guidance, L137, HSE.
· Guidance on permit-to-work systems: A guide for the petroleum, chemical and allied industries, HS(G)250, HSE, and
· Code of Safe Practice Part 16 – Tank Cleaning Safety Code.Energy Institute, 2008
It also urges tank operators to make sure they review their arrangements for cleaning tanks that contain hazardous substances and make sure their practices are up-to-date.
