Answer 9

Transformers contain up to 2000 gallons of transformer oil. Although most PCBs have been removed from transformers, there are some that still contain PCBs and full PPE and SCBA use shall be mandatory. Which transformer fire tactic is incorrect? A: Water applied to a failed transformer with a combustible liquid fire may cause a boilover, which is the rapid expansion and expulsion of vaporized oil. A boilover usually causes a large plume of burning liquid to expel from the container. B: Water is acceptable to use to protect exposures but applying water directly on the transformer should be avoided as an initial tactic. C:✔Transmit a 10-86 Signal (for Purple K, F500 and Foam Response).

Arcing can also be indicated by hissing, buzzing or crackling noises without a visible indicator. D:✔A transformer fire will present with an extremely heavy fire condition usually with flames burning 4 or more feet in the air. This is a true transformer fire, and is the combustible oil inside the transformer burning. Explanation: D) A transformer fire will present with an extremely heavy fire condition usually with flames burning 10 OR MORE FEET in the air.

(Await Con Ed if possible, using water and proper stand-off distances if necessary) C Note: While it is common for this condition to occur on cables in a manhole, if it occurs on a transformer, this condition can result in catastrophic failure of the transformer. Isolate the area of civilians, and FD members should monitor from an area of safety. There are no actions members can take to prevent catastrophic failure. You cannot suppress a transformer fire with sustained arcing. The electric utility must remove power from the unit. AUC 180 6.1
