Used very rarely, one
negative side effect
is the concern of the
human population
should there be a
significant kill off of a
large number of
birds leading to

conditions. Ensure that sub
contractors receive training on
the Heat Stress Program

Activity Level
Discretion is required when planning heavy exercise for acclimatized personnel.
Strenuous exercise and activity for new and un-acclimatized personnel during the first 30 days of heat exposure.
Strenuous exercise should be curtailed for personnel with less than 12 weeks of training in hot weather.
Physical training and exercise should be curtailed for all personnel (operational commitments excluded).
Heat stroke likelihood is high under conditions of high exertion.
