smokejumper fire call begins
with the arrival of a Smokejumper request at the unit dispatcher's office.
mokejumpers
begin to suit up as the spotter, a smokejumper supervisor who will serve
as jumpmaster on the flight, receives the request and plots the fire's
location on the map. When suited up, the jumpers board the aircraft, which
has been preloaded with their firefighting equipment. Within
ten minutes after receiving the request, the aircraft is loaded and taxis
to the runway for takeoff.
pon arrival over the fire,
the spotter and the smokejumper crew leader discuss the fire situation
and choose a jump spot, the area in which they want the jumpers to land.
They also determine the number of jumpers required to suppress the fire.
On small fires, only two jumpers may be needed; larger fires may require
20 or more. The spotter throws weighted crepe paper drift streamers from
the aircraft over the selected jump spot to determine wind direction and
velocity, information the jumpers need to maneuver their parachutes into
the selected jump spot.
he plane makes several passes
over the
jump spot as smokejumpers parachute from the aircraft one, two, or three
at a time - most jump spots are small, and only a few jumpers at a time
can safely land in them
pon landing, the jumpers
quickly remove their parachutes and jump suits.
The plane circles, dropping to an altitude of 200 feet above the treetops.
The spotter then drops the needed equipment via cargo parachute.
he crew leader checks the
fire to determine whether enough jumpers and equipment have been dropped
and that all the jumpers have landed safely. Then the crew leader radios
the aircraft and lets the spotter know that the aircraft can leave the
area. It's now time for the smokejumpers to go to work.
s the jumpers remove their
tools from the cargo boxes, the crew leader sizes up the fire and determines
the tactics to be used to fight it. The first task for the crew leader
is to find a safety zone, an area into which the jumpers can retreat should
the fire blow up. The crew leader notifies the jumpers of the safety zone's
location, the routes to the zone, and what the signal will be if it's
necessary to take refuge.

jumpers then begin to cut and dig a fireline around the edge of the fire.
Firelines are constructed on the perimeter to deprive the fire of fuel,
thereby stopping the fire's spread. Depending on the fire's intensity,
firelines can be anywhere from a few feet to 200 feet wide. Burning trees
and snags are felled and bucked with chainsaws or crosscut saws. Areas
adjacent to the fire are carefully searched for "spot" fires, separate
fires started by wind-drifted embers from the original fire. On larger
fires, it may be necessary to order in airtankers to drop fire retardant,
or helicopters with large buckets underneath to drop water to cool the
flames.
nce
the fireline is completed and the fire is contained, the smokejumpers
begin "mop-up." During the mop-up stage, the fire is completely extinguished
by mixing smoldering fuel with cool, moist soil. If available, water is
applied with portable pumps and fire hose, or with backpack pumps. Only
when the fire is totally controlled do the smokejumpers get an opportunity
to rest. They remove the sleeping bags from the cargo boxes and look for
a level spot to sleep, no easy task given the rugged terrain most smokejumper
fires are located in.
fter a few hours of rest,
the smokejumpers begin their final check of the fire. This necessitates
checking the entire fire area, inch by inch, for any remaining hotspots.
The jumpers get down on their hands and knees and feel the entire burned
area with their bare hands. The area must be cool to the touch before
the fire can be declared out.
s
the final check begins, the crew leader contacts the local dispatcher
and begins making arrangements for the smokejumpers to leave the fire.
This is a difficult task; each jumper has about 110 pounds of tools and
equipment to carry, and smokejumper fires are seldom near roads. The jumpers
must arrange to be picked up at the nearest road and then must determine
how to get there. In some cases, they are retrieved by helicopter. Other
times, a mule train or pack string is sent in to get the gear; often the
jumpers backpack their gear to the nearest road. Back at their base, it
may only be a matter of hours before they are off on another fire call.
