D.A.L.L.A.S.

Question 12

Direction of MALE THREADS, NORMALLY point in?

Answer 12

Direction of WATER FLOW

• Couplings are made HAND TIGHT, use a SPANNER if couplings leak
• do NOT drag butts….carry butts, pull hose

Question 13

Apparatus shall not be driven over lines, unless ABSOLUTELY NECESSARY

Answer 13

CHARGE LINE if possible

• avoid running over couplings
• minimum speed
• 5 inch hose not driven over, UNLESS properly bridged

Question 14

Hose stretch outside buildings, fire escapes, stairwells should be secured with?

Answer 14

HOSE STRAPS

Question 15

Transport Frozen HOSE to quarters:

Answer 15

• 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

Question 16

HOSE shall be removed and CLEANED WHEN?

Answer 16

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 )

Question 17

Hose used to carry salt water should be ?

Answer 17

FLUSHED throughly with fresh water

Question 18

If serviceability of hose is in doubt, test it to?

Answer 18

250 PSI

Question 19

Before connecting hose, check for cracks, out of round, burred threads, and presence of ?

Answer 19

WASHER(female coupling)

-to check washer remove it and fold it between your thumb and forefinger

spare washers- tech services

Question 20

No MORE than ____lengths of 1 3/4” hose shall be used as lead?

Answer 20

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

Question 21

DO NOT permit hose to LIE OVER ITS EDGE…

Answer 21

load hose from LEFT To right

-when reloading hose should be reconnected JUST PRIOR to reaching the bed, ensures PROPER DRAINAGE

Question 22

ROLLED lengths

Answer 22

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

Question 23

Folded LENGTHS :

Answer 23

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

Question 24

HOSE TEST:

Answer 24

-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

Question 25

Company Commanders establish method whereby …

Answer 25

a length of 3 1/2” hose can be stretched form EITHER SIDE of the apparatus in the even a hydrant hookup with a standard hydrant connection is not feasible
