What are the fire risks associated with mineral oil in transformers?

The fire risks associated with mineral oil in transformers primarily stem from its flammability and low flash point. When mineral oil is exposed to high temperatures or electrical faults, it can ignite, leading to potential fires or explosions. Additionally, leaks or spills can create hazardous conditions, especially in confined spaces. Proper maintenance, monitoring, and the use of fire-resistant alternatives can mitigate these risks in transformer operations.
