The International Association of Oil and Gas Producers (OGP) have published the following safety alert regarding an incident in which an explosion occurred. The incident occurred at a location during restoration activities on a crude oil tank which had been cleaned up. Two workers were carrying out hot work on the top of the tank floating roof (cutting rim seal brackets in close proximity to the pontoon). One of the pontoon compartments exploded. Flammable residue was released onto the tank floor causing a small fire.
In this case, workers sustained moderate injuries. However similar accidents involving hot work on floating roofs after tank clean-up had taken place in the past and led to more severe injuries and fatalities.
