Exposure to heat can cause illness and death as a result of increased internal body temperature. Due to long hours spent working outdoors, farmers and ranchers are at increased risk of suffering a heat-related illness.

DID YOU KNOW…
Exposure to heat can cause illness and death as a result of increased internal body temperature. More worker compensation claims for heat illness come from workers in agricultural than from any other occupation.
The most serious heat illness is heat stroke, which can be fatal. Other heat illnesses, such as heat exhaustion, heat crampsand heat rash, are important indications of excess exposure to heat.
HEAT-RELATED ILLNESS: KNOW THE SIGNS
It’s important to know the signs of heat illness—acting quickly can prevent more serious medical conditions and save lives.
Heat Stroke is the most serious heat-related illness and requires immediate medical attention. Symptoms include confusion, fainting, seizures, very high body temperature and hot, red, dry skin or profuse sweating. CALL 911 if anyone shows signs of heat stroke.
Heat Exhaustion is also a serious illness. Symptoms include headache, nausea, dizziness, weakness, thirst, muscle cramps, and heavy sweating.
Heat Fatigue and Heat Rash are less serious conditions, but they are still signs of too much exposure to heat.
If you or a coworker has symptoms of heat-related illness, you must act immediately. Move the affected person to a shaded area, loosen his/her clothing, give him/her water (if he/she is able to drink), and cool him/her down with cool water.
What circumstances lead to heat illness?
- High temperature and humidity with limited air movement
- Direct sun exposure
- Low fluid intake
- Heavy physical labor
- Wearing chemical protective clothing
- No recent exposure to hot workplaces
BEAT THE HEAT: FOUR SIMPLE STEPS
WATER: Water helps prevent heat illness — drink a quart of water every hour. Don’t wait until you feel thirsty. “Sport drinks” are useful. Caffeinated and sweetened beverages (cola, coffee, tea) are less helpful. Do not drink alcoholic beverages when working in the heat – alcohol dehydrates the body.
REST: Rest breaks help you recover from heat and let your body temperature cool down. Take frequent breaks when working in hot conditions
SHADE: Resting in the shade or in air-conditioning helps you cool down. Be sure to have a shaded or cool place to rest.
TOLERANCE: Workers who are not used to hot conditions should gradually increase daily time spent in hot conditions.
