Summary
This bulletin describes two fatal refinery incidents involving corroded tanks: a hot-work ignition of flammable vapours and an operator falling through a weakened hot-oil tank roof during manual measurement. It highlights uncorrected defects, reporting and escalation of corrosion concerns, and avoiding access onto unsuitable or badly corroded equipment.
