Transformer Foundation - Oil Containment Area Sizing

Mar 24,2011 kazakhstan transformer tank fire volume#0183;I am working on a design of a transformer foundation.Transformer contains 1050Gal of oil.That is quite a bit of oil,that would require 146 cu.ft.of containment volume around the transformer pedestal,if I add crushed stone into the pit,it will quadruple the volume.I have an option of building an underground containment tank with a sump pump.Transformer Foundation - Oil Containment Area Sizing Mar 24,2011 kazakhstan transformer tank fire volume#0183;I am working on a design of a transformer foundation.Transformer contains 1050Gal of oil.That is quite a bit of oil,that would require 146 cu.ft.of containment volume around the transformer pedestal,if I add crushed stone into the pit,it will quadruple the volume.I have an option of building an underground containment tank with a sump pump.Transformer Fire Risk Mitigation AureconTransformer fire risk mitigation Current designs cater for a bundwall area around the oil filled transformer to cater for 110% of the transformer oil volume.The standard calls for specific measure around the outer edges of the transformer to contain the oil spillage in the event of a breach of the containment tank of the equipment (Figure
