|
|
Term
Electrical power lines down |
|
Definition
whether or not a fire is started, an area equal to one span between poles should be cordoned off around the break; if a fire does start, firefighters should wait for the fire to burn away a distance equal to one span before extinquishing |
|
|
Term

Definition
coolant liquids may contain PCBs, these are flammable and carcinogenic
use a dry chemical to extinguish transformers at the ground level; at pole-level, allow fire to burn until utility personnel can extinguish with a dry-chemical from an aerial device |
