A series of fire experiments were conducted in two
aircraft hangars with ceiling heights of 15 m (50 ft)
and 22 m (73 ft). The purpose of the experiments was to
analyze the activation characteristics of smoke and heat
detectors in response to JP-5 and JP-8 pool fires. The
15 m (50 ft) hangar was located in Hawaii, where ambient
temperatures were approximately 30 deg C (86 deg F).
The 15 m (50 ft) experiments used fire sizes that ranged
from 100 kW (95 Btu/s) to 7.7 MW (7300 Btu/s).
Experiments were conducted with and without draft
curtains in the 15 m (5O ft) hangar. The 22 m (73 ft)
hangar was located in Iceland, where ambient
temperatures were approximately 12 deg C (54 deg F).
The 22 m (73 ft) experiments used fire sizes that ranged
from 100 kW (95 Btu/s) to 33 MW (31000 Btu/s). Draft
curtains were present for all the 22 m (13 ft)
experiments. Open- and closed-door fire experiments were
conducted in both hangars.
