Question
Emergency plans are being formulated at a plant so that a rapid
action can be taken in the event of an equipment failure. It is
predicted that if a particular pipeline were to rupture, it would
release ammonia gas at the rate of 10 kg/sec. Person exposed
to 300 ppm (IDLH) of ammonia for even a short time would
be in serious danger. Anywhere the ammonia concentration is
that high would have to be evacuated until repairs are made.
What recommendations would you make as to how far from
the rupture people should be evacuated. Assume the release
occurs at ground level, on an overcast night with a wind speed
of 3.5 m/s and a temperature of 50°F.
