What distance should you stand from a pad-mounted transformer fire when applying water?

• A. 10 feet away
• B. 33 feet away
• C. 50 feet away
• D. 100 feet away

Answer: (B)

The main idea is staying at a safe distance from a pad-mounted transformer fire to avoid explosive rupture, splatter of hot oil, or energizing the water path. These transformers can contain flammable insulating oil and may rupture under fire, throwing hot oil, metal, and debris outward. Water applied too close can cause violent steam, splatter, or contribute to an electric shock risk if it contacts live parts. By keeping a substantial distance, you reduce exposure to the blast and potential arc or shrapnel while still being able to cool the surrounding flames and prevent the fire from spreading. The recommended distance is about 33 feet (roughly 10 meters), which balances safety with effectiveness. Being much closer increases risk, while being much farther can limit your ability to control the fire.
