What are the transformer oil containment requirements?

Transformer oil containment requirements mandate that facilities must implement measures to prevent oil spills and leaks from transformers. This typically includes secondary containment systems, such as bunded areas or spill trays, capable of holding at least 110% of the transformer’s oil capacity. Additionally, regular inspections and maintenance of containment structures are essential to ensure integrity and compliance with environmental regulations. Proper signage and emergency response plans should also be established to address potential oil spills.
