Bleve risk hinges on keeping the heated vessel from failing under pressure. The best way to reduce that risk is to cool the tank by applying water directly to the area around the leak. Water absorbs a lot of heat as it converts to steam, lowering the metal temperature at the critical spot and slowing the vapor buildup that drives a rupture. Targeting the leak source with cooling is the most effective way to prevent the shell from reaching failure temperature, buying time for evacuation and additional resources. Moving in extremely close or attempting to ventilate won’t stop the heat buildup and can expose you to blast hazards or spreading vapors, and sending water from far away generally won’t transfer enough heat out of the vessel quickly enough to prevent a BLEVE.
