how to store transformer oil drums?

To store transformer oil drums safely, ensure they are placed in a well-ventilated area away from heat sources and direct sunlight. Use a flat, stable surface to prevent tipping, and keep them upright to avoid leaks. Implement secondary containment, such as spill pallets, to manage any potential spills. Label the drums clearly and maintain an inventory log. Regularly inspect the storage area for leaks or damage to ensure safety and compliance with regulations.
