What to do if a transformer is leaking oil?
Transformers play a vital role in supplying reliable electricity, but when one begins to leak oil, it raises immediate safety, environmental, and regulatory concerns. Leaking transformers—whether located on an electric pole transformer, a telephone pole transformer, or inside a pad mount transformer enclosure—should never be ignored. Knowing how to identify a transformer oil leak, what steps to take, and which solutions to use can make the difference between a controlled situation and a costly, hazardous incident.
ABG Bag Inc specializes in sustainable, compliant containment products that are designed to manage situations like transformer leaks safely and efficiently. From transformer oil removal to PCB transformer removal and containment, ABG provides solutions that keep workers, communities, and the environment protected.
Why transformers leak oil
Transformers use oil as both an insulator and coolant. Over time, wear and tear on seals, corrosion of the casing, or impact from storms and accidents can cause a transformer utility pole unit or pad mount transformer to begin leaking. In older equipment, leaks may involve PCB oils, which require careful handling and removal under strict environmental guidelines. Even in newer units without PCBs, a transformer oil leak still poses contamination risks and must be addressed quickly.
Signs of a transformer oil leak
There are several ways to recognize a transformer oil leak before it escalates:
-
Visible oil stains on the outside of the transformer utility pole casing
-
Dark, greasy patches on the ground below an electric pole transformer or pad mount transformer
-
Oil residue streaking down the sides of a telephone pole transformer
-
A noticeable odor near the equipment
If these signs appear, prompt action is necessary to reduce environmental contamination and prevent electrical hazards. For more detailed guidance on spotting early leaks, ABG Bag Inc provides resources such as the Guide To Identifying And Managing Leaking Utility Transformers.
Immediate safety steps to take
Safety should always come first when dealing with a power pole transformer leak. These steps are recommended:
-
Stay clear of the transformer and do not touch any leaking oil.
-
Keep others away from the area until professionals arrive.
-
Notify the appropriate team or utility to report the issue.
-
Document the leak with photos to assist in reporting and remediation.

Environmental risks of transformer oil leaks
Oil from leaking transformers can contaminate soil and groundwater, especially if it contains PCBs. Even non-PCB oils pose cleanup challenges, as improper handling can lead to regulatory violations and long-term environmental damage. PCB transformer removal requires specialized containment and disposal tools to meet UN, DOT, TSCA, and EPA standards. ABG Bag Inc designs and manufactures containment bags and products that are compliant, recyclable, and reusable, ensuring safe transformer oil removal and transport.
Containment solutions for transformer leaks
When a transformer begins to leak, containment is critical. ABG Bag Inc’s product line includes transformer containment bags specifically engineered for pole-mounted and pad-mounted units. These bags are designed to fully enclose the leaking transformer, prevent further oil release, and allow for safe lifting, storage, and transport.
For pad mount transformer leaks, ABG’s FlexTrays and containment berms provide effective solutions to capture oil during movement or while the equipment is staged. For electric pole transformer or telephone pole transformer leaks, specialized containment bags with full-sling lifting capability make transport safer and more compliant.
Transformer oil removal and handling
Once contained, transformer oil removal must follow strict protocols to ensure safe disposal or recycling. ABG Bag Inc’s products streamline this process by capturing all oil within a sealed, certified containment system. This eliminates risks of secondary spills during handling and aligns with regulatory compliance. Using the proper tools ensures safe operations and minimizes liability for those responsible for managing transformer leaks.
When replacement is necessary
In some cases, minor leaks can be repaired with seal replacements or maintenance. However, if the casing is damaged or the transformer has aged beyond reliable repair, utility transformer replacement is the most practical and safe option. Replacing damaged units reduces ongoing risks of transformer oil leaks, improves efficiency, and ensures compliance with modern safety and environmental standards.
The role of PCB transformer removal
Older transformers that still contain PCBs represent one of the most serious concerns when it comes to transformer leaks. Because of the hazardous nature of PCBs, their removal must always be managed with approved containment solutions. ABG Bag Inc offers transformer containment bags designed to handle PCB transformer removal safely, ensuring total encapsulation during transport and disposal. By using certified products, organizations can meet compliance requirements and avoid the long-term environmental risks of PCB contamination.
