Wildfire Fighting Near High-voltage Electric Transmission Lines Owned By PG&E
1. FIRE FIGHTING OPERATIONS 100 FEET BEYOND THE OUTER MOST WIRE OF AN ELECTRIC TRANSMISSION LINE REQUIRE NO UNUSUAL TACTICS
Tactics should consider transmission lines to be an exposure requiring protection when threatened by fire. When possible, establish a Control Line to prevent the spread of fire into the area within 100 feet of and parallel to the edge of the outer most phase conductor. Smoke, ash, and incidental mist from fire fighting operations can contaminate the insulators on transmission structures. This contamination may cause a short-circuit to occur at the structure, creating an electrical hazard. Maintain a minimum radial distance of 35 feet between firefighters (and vehicles) and transmission structures to protect fire fighting personnel from this electrical hazard.
2. FIRE FIGHTING TACTICS WITHIN 100 FEET OF THE OUTER MOST WIRE OR UNDER TOWER LINES REQUIRE SPECIAL TACTICS FOR FIREFIGHTER SAFETY
If the grass or brush fire has extended to the area within 100 feet of the outer most ...
