Abstract:
A series of eight fire tests were conducted to evaluate
the level of protection required to control a fire in
double row rack storage of palletized isopropyl alcohol
in high density polyethylene (HDPE) plastic containers.
The containers ranged in capacity from pint to gallon
and were stored in corrugated cardboard cartons on
hardwood pallets. the total amount of isopropyl alcohol
used in each fire test ranged from 240 gallons to 1560
gallons. The first seven fire tests were conducted in a
double row rack storage array with barriers and in-rack
sprinklers. The last test was conducted in a palletized
storage array under the protection of the ceiling
sprinklers only. Fire Test No. 1 through Fire Test No.
6 were ignited with two gallons of alcohol in two 2 ft.
x 2 ft. x .75 in. steel pans located halfway within the
plane of the center south face at the floor. Fire Test
No. 7 utilized four cotton cellulose ignitors each
measuring 3 in. long by 3 in. in diameter with 4 oz. of
gasoline arranged around a point at the floor in the
center of the south face. Fire Test No. 8 utilized a 6
in. long by 3 in. in diameter cotton cellulose ignitor
with 8 oz. of gasoline at a point centered within the
south flue space. The sole purpose of this
investigation was to develop test data relative to the
protection of mixed rack storage of palletized water
miscible flammable liquids in plastic containers using a
wet pipe ceiling and in-rack sprinkler systems.
