Question

Fire is to blame for the loss of countless
lives and billions of rupees each and
every year. Firefighters help protect
people and their property from injury
and damage. They put their lives on the
line every time they respond to a call.
While on duty, firefighters must be ready
to respond in a matter of minutes to just
about any disaster that may occur. At
every fire scene, a superior fire officer
takes command and directs the jobs of
all the people at the scene. Some fire-
men connect the hose lines to hydrants.
Others manually operate the pumps to
send water to the hoses. Teams of
firefighters also operate ladders used to
reach distances high in the air.
