High pressure has maximum working pressure of ?
600 PSI
SATELLITE Water System uses?
5 inch diameter hose with 4 1/2” couplings
Each Engine maintains?
20- 1 3/4” hose
30- 2 1/2” hose
10- 3 1/2”
this INCLUDES WINTER OPS/STANDPIPES/REPLACEMENT LENGTHS
DATE of ISSUANCE?
FEMALE COUPLING- females go on dates
Company/Registry numbers?
MALE- male makes for a better COMPANY
-manufacture date–both ends , 4 feet or more from couplings
Date of ISSUANCE is recored in ?
OFFICER RECORD JOURNAL
PRESSURES exceeding _____can ONLY be ordered by IC?
250 PSI
In order to provide correct pressure in a hoseline?
- TYPE OF NOZZLE and/or size of tip
- NUMBER of lengths and SIZE
- NUMBER OF FLOORS above or below grade
Never attempt to straighten kinks____?
Hydraulically
Use of 1 3/4 INAPPROPRIATE , use 2 1/2” during these circumstances?
- DEFENSIVE POSITION
- ADVANCED fire on Arrival
- LARGE VOLUME of water for superheated fire area
- LARGE body of fire in LARGE uncompartmented area
- AREA OF FIRE-SIZE AND cannot DETERMINED
- STANDPIPES
D.A.L.L.A.S.
Direction of MALE THREADS, NORMALLY point in?
Direction of WATER FLOW
- Couplings are made HAND TIGHT, use a SPANNER if couplings leak
- do NOT drag butts….carry butts, pull hose
Apparatus shall not be driven over lines, unless ABSOLUTELY NECESSARY
CHARGE LINE if possible
- avoid running over couplings
- minimum speed
- 5 inch hose not driven over, UNLESS properly bridged
Hose stretch outside buildings, fire escapes, stairwells should be secured with?
HOSE STRAPS
Transport Frozen HOSE to quarters:
- Frozen hose transported pumper, provided LONG ROUND TURNS are made when placing it on apparatus
- handled/bent AS LITTLE AS POSSIBLE
- IF SOLID, consideration given to transport via AERIAL LADDER …laid out straight
- upon return to quarters lay out hose and allow to dry NATURALLY
Free Frozen couplings:
- thawing apparatus
- exhaust of apparatus
Free frozen hose:
- chop away ice
- thawing apparatus
HOSE shall be removed and CLEANED WHEN?
SPRING /FALL
ANY hose reaching 10 years is to be taken OOS–NOTIFY FIRE TOOLS/EQUIPMENT UNIT VIA FAX
stamped coupling - 970023–“97” is year (this must be replaced in 2007–10 years )
Hose used to carry salt water should be ?
FLUSHED throughly with fresh water
If serviceability of hose is in doubt, test it to?
250 PSI
Before connecting hose, check for cracks, out of round, burred threads, and presence of ?
WASHER(female coupling)
-to check washer remove it and fold it between your thumb and forefinger
spare washers- tech services
No MORE than ____lengths of 1 3/4” hose shall be used as lead?
6 lengths
typical hose load:(can vary depending on response area)
one bed of 2 1/2”
one bed 3 1/2”
two of 1 3/4” –coupled to 2 1/2” hose
DO NOT permit hose to LIE OVER ITS EDGE…
load hose from LEFT To right
-when reloading hose should be reconnected JUST PRIOR to reaching the bed, ensures PROPER DRAINAGE
ROLLED lengths
ROLL so MALE end is inside
place male end 3 feet from female coupling
HOSE SENT TO DIVISION OF TECH SERVICES (not fire tools /equipment) with MALE BUTT INSIDE
Folded LENGTHS :
2 butts side by side…FACING BUTT, MALE on your left
for LEAD LENGHT with NOZZLE…NOZZLE TIP EVEN with female butt
STRAP tight enough so butts will not flap around
HOSE TEST:
-hose butts free of dirt/debris
-visual inspection while preparing it for test/prior to charging lines
-connect pumper to hydrant on inlet OPPOSITE CONTROL PANEL
-ALL connections SPANNER TIGHT
-attach one way gate to pumper outlet
-attach 4 1/2” to 2 1/2 “ reducer to 6 WAY MANIFOLD
-ATTACH IN LINE HOSE TEST GAUGE
(before starting, check tightness of INLINE GAUGE set screw)
-MAX 2 LENGTHS of hose from one way gate to hose test gauge (hose must be stretched from outlet OPPOSITE CONTROL PANEL(just like hydrant hook up)
NOTE: ONLY SUPPLY WITH 2 1/2” HOSE
-RELIEF VALVE should be CAPPED and FULLY CLOSED during test
-MAX 6 LENGTHS stretched from each 2 1/2” GATED OUTLET on manifold
-attach DRAIN VALVE CAP to MALE COUPLING to last length
-DRAW line as close to possible to MALE BUTT (water soluble marker)..movement of 1/8 INCH or more indicate male butt and hose are SEPARATING …OOS
CHARGE MANIFOLD with HYDRANT PRESSURE
- BLEED AIR by opening SPIGOT on cap…when water is flowing freely …then close spigot
- FF to left 15 feet from left side of manifold, facing hose…all other members safe distance, securing area
- ECC will gradually increase pressure to 250 PSI on hose test gauge
OFFICERS MAKE FINAL INSPECTION OF ENTIRE HOSE TEST SYSTEM …MOVES TO SAFE POSITION AND INSURES SAFETY OF MEMBERS
250 PSI for 5 MINUTES and then gradually reduce pressure
