Question 14

Hose removal
Repacking
Out of service

Answer 14

Removed/repacked spring&fall
10yrs+ out of service
First 2digits of serial# on female coup. Indicates year made
Female couplings have rubber washer
Out of service- RT3 form, attach to hose
Replacement- fire tools & equipment

Question 15

Rolled hose

Answer 15

Lay hose out then fold back on itself
Lay male coupling 3ft from female
Roll @ folded end

Single roll- out of service, male coupling inside, over hand not 3” from female

Question 16

Roll ups

Answer 16

Fold hose in half so nozzle tip eve w/ female coup.
Midpoint fold to coupling
Fold up the coupling over midpoint
Lift couplings then fold
Male coupling on right
A fold- painted red, midpoint beneath couplings

Horseshoe

Answer 17

Comprised of 1 length of hose 4ft long

Midpoint of horseshoe by grabbing middle ring

Question 18

Hose bed

Answer 18

Load hose from left to right w/ coupling extended beyond hosebed
