Application of water streams on energized electrical equipment Flashcards
HANDLINES shall NEVER be used on energized electrical components at con ed facilities
energized-equipment connected to electrical source
de-energized-isolated from all electrical source but NOT GROUNDED
grounded- electrically isolated and grounds applied
Decisions to apply streams to electrical components at Con ED facilities will..?
NOT be undertaken by first arriving units
ONLY made by a CHIEF OFFICER above rank of DC in consultation with white hat at scene
Minimum safe distances for applying water on energized/de-engerized electrical components?
15 ft on live 138kV-30 deg. or greater Fog
75 ft on live 138kV-straight or solid and streams less than 30 deg.Fog
25 ft on live 345kV- 30 deg or greater FOG
125 ft on live 345kV-straight or solid and streams less than 30 deg Fog
these distances are from TIP OF NOZZLE to ENERGIZED EQUIPMENT
Primary means of application?
TOWER LADDER
- clear all sediment -flush hydrant thoroughly
- type of tip-depend on ability to reach-stacked tips= solid…akron turbomaster=straight to fog
- waterway of TL must be flushed away from point of operation-several minutes until water runs clear
- All members removed from basket and basket is then raised to operating position..ALL MEMBERS REMOVED FROM APPARTUS
- stream then applied
- stream not reaching-shut down from pumper and repeat process
If conditions don’t allow for TL use, consider?
Engine apparatus deck gun
aerial ladder pipe
portable akron new yorker
DO NOT use AQUASTREAM MASTER NOZZLE
NEVER enter inside con ed facility property line, unless..?
escorted by Con ED personnel and approval of INCIDENT COMMANDER
- NEVER use salt water on live electrical components
- clear all sediment before hooking up
- no additive/including foam
- desired fog is 30 degrees or greater
- fog streams affected by win-use straight/solid
- do not touch, move, adjust any part of device while delivering water to energized electrical equipment
- run-off water from Con ED being charged is extremely unlikely, however, AVOID WATER RUN-OFF
