Q

Standpipe categories :

A

WET-contain water in riser at all times supplied by CITY main, gravity tank, pressure tank, and/or fire pump…combination- standpipe and sprinkler, MOST are wet …water flow demands for both sprinkler and standpipe required proper augmentation

DRy- may be equipped with an automatic source of supply, but many contain NO WATER and only supply is from FD pumpers (this is called manual dry system)

Q

________INSERT any part of your hand inside siamese connection?

A

NEVER
-spare 3” MALE cap carried by all engine companies in the event it becomes necessary to cap one side of the siamese connection to prevent an outflow of water due to a malfunctioning CLAPPER VALVE

another way to remedy this problem is

IMMEDIATELY stretching a 3 1/2” line and connecting

Q

ALL MEMBERS, particularly ECC’S should monitor HT transmissions for indications that pressure to the standpipe system needs to be increased …

PRESSURE CHART:
1-10…150
11-20…200

SO ON SO FORTH

A

Buildings under 2008 code having a standpipe riser OVER 600 FEET in height, shall have separate “low zone” and ‘high zone’ siamese connections …these are NOT INTERCONNECTED (must supply correct one)….connections shall be identified with SIGNAGE stating either “low zone” OR “HIGH ZONE” and indicate the floors they serve…high zone also know as EXPRESS PIPING

-operations will be in accordance with High pressure pumping

buildings with express piping should be subject of familiarization drills and include in the CIDS program

Q

FIRST ARRIVING CONTROL FF:

A

Remain at standpipe outlet throughout the operation and communicate with the first arriving engine officer to ensure that adequate pressure is supplied to the nozzle. He shall ensure a proper hook up to the standpipe outlet. remain in CLOSE PROXIMITY to the standpipe outlet throughout the operation in case adjustments are needed …..IN LINE PRESSURE GAUGE should always be used to ENSURE CORRECT nozzle pressure

17
Q

Control man should be aware, that kinks, cracking or shutting down the nozzle, during the operation will also cause pressure displayed on in line pressure gauge to increase and should refrain from adjusting the valve

A

As General rule: with WATER FLOWING:

  • standpipe operations with a 2 1/2” lead length with 1 1/8” MST, the outlet pressure of 70 PSI FOR 3 LEGTHS and 80 PSI for 4 lengths
  • Below grade operations, head pressure will increase 5 psi for every 10 feet below grade….pressure may HAVE TO BE REDUCED accordingly
  • Air conservation is an important consideration for the SECOND ARRIVING ENGINE…if not possible to conserve air due to products of combustion the IC must be notified so that additional engine companies can be utilized to reinforce the critical position of first hoseline
  • SCISSOR STAIRS -requiring 4 or more lengths should be in CIDS
18
Q

Conventional Engine:

A

2 stage 1000 gpm or 2000 gpm engines

19
Q

High Pressure Engines:

A

2 stage 1000 Gpm or 2000 Gpm engines
-special high pressure discharge elbow

OVER 250 PSI and UP TO 600 PSI

20
Q

3rd stage Engine:

A

engine with a 3rd stage

-can supply MAX 500 GPM/700 psi (so 600 PSI –700 PSI—3RD STAGE)

21
Q

High pressure and 3rd stage have following equipment:

A
  • 3” high pressure supply hose, 50 feet per length
  • high pressure fittings
  • high pressure outlets (one on HP/2 ON 3RD STAGE)
  • TETHER STRAPS with gated hooks (strap contains velcro bands)…units should pre attach tether strap to hight pressure hose
22
Q

High Pressure pumping is defined as operating at discharge pressures over _______?

A

250 PSI
IC shall be notified when high pressure pumping is necessary

conventional Engines should not operated in excess of 250 psi (although they are capable), unless EMERGENCY AND IC APPROVAL

23
Q

When HIGH PRESSURE PUMPING operations are in use, following precautions are to be followed:

A
  • High Pressure or 3rd stage Engine must use HIGH PRESSURE hose and fittings , painted WHITE and NOTICEABLY HEAVIER and TETHER STRAP (recommended units pre attach tether strap)
  • if possible, Engine positioned within 1 length of FD connection/ NOT MORE THAN 2 LENGTHS
  • SAFETY ZONE on EACH SIDE OF ENGINE AND SUPPLY HOSE (tape, rope. stanchion)…at least 50 feet in ALL DIRECTIONS around working engine and supply hose..if two connected lengths are in use, safety zone may need to be expanded
  • all unused gates closed and capped TIGHTLY
  • Each ENGINE controlled by ECC AND ASSISTED BY AN ECC from NON PUMPING ENGINE…One ECC WILL OPERATE and ONE WILL MONITOR HT TRANSMISSIONS…other ECC’S OF NON PUMING engines shall keep people out of the safety zone
24
Q

More precautions:

A
  • SUPPLY LINES SECURED WITH TETHER STRAPS, BOTH ENGINE AND BUILDING FD CONNECTION AND EACH LENGTHS TETHERED TO EACH OTHER, if 2 are used
  • no tether straps, use UILITY ROPE
  • BC SHOULD be designated HIGH PRESSURE PUMPING GROUP SUPERVISOR, but operation may be implemented prior to their arrival
  • IC should ensure building occupants avoid stairwells
  • STAIRWELLS SERVED BY STANDPIPES may NOT BE USED as rest areas or staging during HIGH PRESSURE PUMPING OPERATIONS..use minimum amount of personnel in these stairways (JUST MENTIONS STAGING/REST…does not mention other FF activities )
  • DO NOT use PRESET on pro pressure governor…once supply line is charged, pressures are to increased slowly
25
Q

When OTHER than first due at fire in HIGH RISE BUILDING, Officers of high pressure engines and 3rd stage engines shall direct their ECC’s to position the apparatus at a hydrant in close proximity to the standpipe siamese connection

A

the standpipe system should be supplied by TWO ENGINES…this will require more than one High pressure or 3rd stage engine to be assigned or special called TO the incident if pressure higher than 250 PSI ARE REQUIRED

26
Q

WHEN only ONE building siamese is available…stretch line to…?

A

FIRST FLOOR OUTLET

do NOT connect TWO HIGH PRESSURE SUPPLY LINES to a single building siamese

27
Q

3rd stage is pressures exceeding ______?

A

600 PSI
-3rd stage implemented…IC shall ensure additional 3rd stage engine is assigned

only IC AT THE RANK OF BC OR HIGHER may order use of 3rd stage (high pressure–IC …could be first due officer)

-3rd stage pump higher volumes at pressures over 500 PSI AND WILL DO SO at LOWER RPMS

THIS INCREASE EFFICIENCY, MAKES 3RD STAGE THE PREFERRED CHOICE FOR PUMPING OPERATIONS REQUIRING DISCHARGE PRESSURES OVER 500 PSI(although high pressure pumping is 250-600 psi???)

28
Q

AIR PRESSURIZED Manual Dry standpipe is required at buildings UNDER CONSTRUCTION upon reaching a HEIGHT greater than 75 FEET or buildings undergoing demolition with an EXISTING standpipe (2014 buildings code).

A

The entire system , including riser, cross connections, siamese connections are pressurized by a dedicated AIR COMPRESSOR

29
Q

Air pressurized standpipe is designed to _________?

A

ALERT workers on site , when standpipe has been compromised

  • when the air pressure drops below a predetermined pressure due to an OPEN VALVE or BROKEN PIPE in the system, or pressure rises above 25 PSI, AN AUDIBLE ALARM will sound only at site (supervisory pressure will vary but will always be below Max 25 psi.
  • audible alarm will continue until opening is CLOSED allowing the compressor to slowly bring air pressure back into the supervisory range or excessive pressure is reduced to below 25 PSI
30
Q

When alarm sounds?

A

construcTION must CEASE and FDNY MUST BE NOTIFIED

  • no construction or demo work should resumed , except to repair standpipe
  • concrete pouring is permitted*
  • any portion of standpipe compromised above closed section valve will NOT cause activation of the alarm , due to pressure being maintained constant in lower portions of the standpipe
31
Q

To use an AIR PRESSURIZED standpipe, air pressure ?

A

MUST BE RELEASED from system PRIOR to uncapping the siamese and supplying it with water.

32
Q

A 2 1/2” manual air release/drain valve (usually standard standpipe outlet) is required to be installed IMMEDIATELY adjacent to the siamese connection…

A

remove the MANUAL AIR RELEASE VALVE CAP and OPEN VALVE FULLY…air will be heard escaping..

  • ECC shall not remove the siamese caps UNTIL AIR PRESSURE HAS BEEN EXPELLED FROM THE SYSTEM
  • NUMBER of valves required to be such that air pressure will be released in NO MORE THAN 3 MINUTES
33
Q

When encountering systems with more than one manual air release vale,?

A

ALL MANUAL AIR RELEASE VALVES should be opened

34
Q

Once air pressure is expelled, siamese caps can be safely removed …

A

CONNECT supply line , CLOSE MANUAL AIR RELEASE VALVE and supply standpipe

-NOT NECESSARY TO deactivate air compressor…it will SHUT OFF , when the standpipe is supplied with water

  • this siamese should be marked with RED LIGHT at night
  • SIGNS are required indicating standpipe is PRESSURIZED WITH AIR, as well as LOCATION OF MANUAL AIR RELEASE VALVE
35
Q

If air is noticed escaping UNDER PRESSURE from a siamese cap while being loosened, and not SIGN is present, member should stop cap removal immediately and ?

A

NOTIFY INCIDENT COMMANDER of pressurized standpipe.

-steps will be taken to bleed air prior to removing caps

36
Q

SCREW IN type caps are REQUIRED in order to provide air tight seal …

A

BREAKaway caps or other NON screw in type are INDICATIVE of NOT PRESSURIZED AIR STANDPIPE

37
Q

Control FF should:

A

after reaching floor outlet…REMOVE CAP, OPEN STANDPIPE OUTLET CONTROL VALVE and wait FOR WATER…this will EXPEDITE AIR REMOVAL (control man takes cap OFF , PRIOR to air removal…different from ECC)

38
Q

During construction, CHECK VALVE (freeze protection) will be bypassed allowing air pressure to reach the siamese connection..

A

Once system has been drained of air and charged with water, water will flow past the bypassed check valves out to ALL SIAMESE CONNECTIONS…if siamese clapper valves are defective or tampered with in the SECOND SIAMESE, its caps may be under pressure

39
Q

Manual air release does not need to be opened when AUGMENTING the standpipe with a SECOND PUMPER…however ,

A

when loosening siamese caps at second siamese, if water begins spraying out under pressure consider the clapper valves inside defective…IMMEDIATELY STOP CAP REMOVAL and use another option for augmenting …examples: supply drain valve next to siamese, use another siamese or supply first floor or another floor outlet…manual air release valve supplied in same manner as you would supply the first floor standpipe outlet as per evolution 10
