What are the regulations for PCB transformer oil?

Production Ban: PCBs have been banned from production in many countries since the late 1970s due to their environmental and health risks.
Labeling and Identification: Transformers containing PCB oil must be clearly labeled and identified for safe handling and eventual disposal.
Disposal Requirements: PCB oils and equipment containing them must be disposed of according to stringent environmental regulations, typically requiring incineration at high temperatures in specialized facilities to prevent environmental contamination.
Retrofitting or Decommissioning: Equipment containing PCB oil must either be retrofitted with non-PCB oils or decommissioned and replaced with modern, environmentally safe alternatives.
Environmental Monitoring: Regular monitoring of sites where PCB-containing transformers are in use or have been decommissioned is required to prevent and detect any leaks or contamination.
Transport and Handling: The transportation and handling of PCB-containing oils are heavily regulated to minimize the risk of spills and exposure, with strict guidelines on packaging, labeling, and documentation.
