Hazard
Overheating transformers and cooling systems
Hazard Knowledge
Transformers generate significant heat and are generally cooled by the circulation of mineral oils. If a transformer overheats, it may rupture; this could result in very hot mineral oil and toxic and/or flammable gases being released.
Some switchgear is also oil-cooled and can rupture in a similar manner to transformers.
