70. WPS safety concept: heat stress
Early-entry workers only!
Prevention, recognition and first aid treatment of heat-related illness
how to prevent, recognize, and give correct first aid for heat illness

71. Heat exhaustion symptoms
Sweating or dry skin
Headache
Fatigue
Dry mouth
Fast pulse (slow if person has fainted)
Nausea
Dilated (large) pupils
Loss of coordination
Confusion
Fainting (quick recovery)
Heat exhaustion symptoms can be very similar to those of pesticide poisoning. A person who has been wearing heavy personal protective clothing and equipment for an extended time during hot weather may be suffering from heat exhaustion rather than pesticide poisoning. Both are serious conditions that will probably require medical attention.

72. Control heat stress Drink lots of water Build up heat tolerance
Take periodic breaks

73. Treatment of heat stress
Get out of the sun
Drink fluids
Loosen or remove clothing
Get help
