What are the health hazards associated with transformer oil?

The health hazards associated with transformer oil primarily stem from its chemical composition, which may include polychlorinated biphenyls (PCBs) if the oil is not mineral-based. Exposure to transformer oil can lead to skin irritation, respiratory issues, and potential long-term effects such as carcinogenic risks. Additionally, improper handling and disposal of transformer oil can result in environmental contamination, posing further health risks to humans and wildlife.
