What is the appropriate action for fighting an above ground transformer fire?

In the case of fighting an above-ground transformer fire, the appropriate action is to contact the power company and avoid using direct hose streams. This approach is important due to the potential hazards associated with electrical fires, particularly those involving transformers.

Transformers contain oil and other flammable materials, and direct water streams can not only be ineffective but also dangerous. Water can conduct electricity and create a risk of electrocution for firefighters and personnel on the scene. Calling the power company ensures that trained professionals can safely manage the situation, as they have the expertise to de-energize the equipment and prevent further hazards.

By avoiding direct hose streams, firefighters can prevent electrical hazards while still working to contain the fire, using other methods deemed safe by protocol or depending on the situation. Firefighting foam may also be utilized, but direct water application should be avoided until professional assistance is on scene to manage the electrical risks effectively.
