A. Spot apparatus a distance from hazard.
B. Be cognizant of high-voltage lines impacted by water from a shared hydrant may arc or fall
C. All member should be alert for additional downed wires, energized exposures
D. Denied entry to scene, locate shut off valve, mitigate threat.
E. Unless a life hazard exist notify an 08 arrival of LA DWP personnel.
D
Although injuries to firefighters from applying water, directly on electrical fires are rare, washrooms applied in the vicinity of high-voltage should be avoided. When hose streams must be used, the following should be adhered to except?
