source is close enough to the fire
scene.
14–41

42. REVIEW QUESTION
What are the common operations for
accessing rural water supplies?
14–42

43. • Because water is the primary fire
extinguishing agent used by
firefighters, and because fires often
occur considerable distances from
major water sources, fire departments
must develop ways to transport the
available water from its source to the
place it is needed.
Summary
14–43
(Cont.)

44. • Firefighters must be familiar with the
water supply systems in their response
areas.
• They must know about water sources,
pumping systems, gravity systems, and
the system of underground water
mains used to distribute the water.
Summary
14–44
(Cont.)

45. • They must also know how to inspect,
maintain, and operate the fire hydrants
in their jurisdictions.
