Water deluge and high pressure water fog or water mist have the benefit , tanzania transformer tank fire volume Continuous combustion requires more than 15% of oxygen concentration by volume, so the above data shows that the gas mixture as stated above is effective for fire suppression.Despite design precautionsvolume of gas builds up, the pressure inside the tank increases significantly. As the metal tank starts to expand, it will deform and may even rupture. The consequences of such an explosion can include oil spills and even extensive fire damage to both the transformer and surrounding equipment. Traditional mitigation methods use, forGuide for Transformer Fire Safety Practicesfor good Transformer Fire Safety Practices that would help transformer designers and users to define and apply best practices in the domain of transformer fire.
