Firefighter I
13–22
Fire Hose Damage — Organic
• Rubber-jacket hose not subject to
damage caused by living organism, but
this is a problem on hose with woven
jacket of natural fiber if stored wet
• Mildew, mold rot fibers of hose jacket,
causing hose to rupture under pressure
(Continued)
Firefighter I

has been chemically treated to resist
mildew, mold; not always 100 percent
effective

location so size-up can be made before
laying supply line
• Most expedient way to lay hose if
apparatus must stay close to water
(Continued)
Firefighter I
13–84
Reverse Lay
• Hose beds should be loaded so first
coupling off hose bed is male

setting up relay pumping operation
when using 2½-inch or 3-inch (65 or
77 mm) hose as supply line
(Continued)
Firefighter I

pumper at hydrant to increase pressure
in supply hose
• Most direct way to supplement
pressure, set up drafting operations
• Disadvantages
(Continued)
Firefighter I

acceptable to hook up on fire floor
(Continued)
Firefighter I
13–100
Advancing Hose From Standpipe
• Steps once at standpipe connection

(Continued)
Firefighter I
13–101
Advancing Hose From Standpipe
• 2½-inch (65 mm) attack line may be
used depending on size, nature of fire

operator with third firefighter kneeling
on hose behind second firefighter
• Another method is for all firefighters to
use hose straps and remain standing
Firefighter I
13–114
Summary
• To fight fires safely and effectively,
firefighters must know the capabilities
and limitations of the various types of
fire hose used in their departments.
