CBRN training in extreme hot weather

In a situation when individuals and units have to work in extreme hot weather, the level of risk increases. To minimize threats hindering a successful operations, there is a need to perform training under the same conditions. It should be considered that:

(1) Heat stress requires shorter work periods and longer break periods in proportion to the level of work performed.

(2) Physical fitness and conditioning of personnel to the climate must be taken into account. Drinking water to avoid dehydration and acclimatisation are necessary.

(3) In extreme hot/dry environment chemical simulants evaporate rapidly; therefore, they should be used immediately prior to training and in shaded areas.

(4) Reduced pace of CBRN defence drills should be conducted.

(5) Also, a defensive scenario will make effective simulation and allow for an easier progress monitoring.

(6) Main exercise play in daylight to aid assessment of the viability of procedures can be considered. Subsequent training can be performed at night when the effects of direct sunlight are removed.

(7) Special arrangements for individuals exercising in individual protection equipment may be necessary.

Any first signs of heat stress, such as rapid breathing and pulse rate, nausea, dizziness, cramp, or a hot, sweaty, flushed face turning pale and cold, require quick action.
