Auc 338 Water On Energized Equipment

Question 0

Con ed terminology

Answer 0

Energized : equipment that is connected to electrical source

De-energized : equipment that is isolated form electrical source but not grounded

Grounded: equipment that is electrically isolated and grounds applied

Question 1

Can you apply water via hand lines to energized electrical components at Con Ed facilities

Answer 1

No never on energized electrical components

Question 2

Who can decide to apply water to electrical components at a con ed facility

Answer 2

Chef above the rank of deputy(deputy who is operating as car 421 car 442)

Question 3

Prior to commencement of water onto energized components the IC MUST DETERMINE the max voltage from con ed white hat .. What are the safe distances

Answer 3

15 feet on live 138kv electrical components for 30 degree or greater fog streams

75 feet on live 138kv electrical components for all straight or solid streams and streams less than 30 degree fog. Distance equal to approximate one and half lengths of hose

25 feet on live 345kv electrical components for 30 degree or greater fog streams..approximately 1/2 length hose

125 feet on live 345kv electrical components for all straight or solid streams and streams less than 30 degree fog… Approximately 2 1/2 lengths

Question 4

The minimum safe distance are measured from where ?

Answer 4

Tip of nozzle to the nearest electrical equipment in the direction of stream

Question 5

What is the primary means of applying water to energized electrical components

Answer 5

Tower ladder

Question 6

When using the TL to apply water to energized equipment at a con ed facility the following procedure shall be adhered to

Answer 6

1. Clear all sediment from water supply by flushing hydrant throughly before connecting to pumper
2. Type of tip used is based on ability to stream to reach target area
3. Waterway of TL must be flushed away from point of operation until,water clear
4. Attach selected tip to basket mounted stang. If using turbo master nozzle set desired stream pattern. Then basket mounted stand set to desired angle and locked into place
5. Safe operating position is determined in conjunction with con ed personnel. Once determined all members removed from basket and basket then raised into operating position. All members are then removed from apparatus. Then stream applied to target area
6. If stream not reaching intended target then water supply shut down at pumper and position of basket angle and or pattern of stream adjusted. Once repositioned and all members off apparatus water is again supplied to TL

Question 7

If you can not use the TL consider the feasibility of engine deck gun, the ladder pipe or Multiversal. When setting up use of the is rpAquastream Master stream IS recommend for the above LCS

Answer 7

No do not use

Question 8

Only enter con ed facilities with members or apparatus with approval of the Con Ed White Hat and escorted by Con Ed Personel. Who will confirm that we are connected to stations ground grid and who will connect us

Answer 8

We will confirm and con ed will connect

Then in notes it says con ed will confirm ?

Question 9

Can you use salt water

Answer 9

No never

No foam

Question 10

Desired degree of fog pattern

Answer 10

30 degree or greater
