HEAT STRESS
Heat Related Injuries Overview

Workers who are exposed to extreme heat or work in hot environments may be at risk of heat stress. Exposure to extreme heat can result in occupational illnesses and injuries. Heat stress can result in heat stroke, heat exhaustion, heat cramps, or heat rashes. Heat can also increase the risk of injuries in workers as it may result in sweaty palms, fogged-up safety glasses, and dizziness. Burns may also occur as a result of accidental contact with hot surfaces or steam.
Workers at risk of heat stress include outdoor workers and workers in hot environments such as firefighters, bakery workers, farmers, construction workers, miners, boiler room workers, warehouse workers, and others who work in unconditioned spaces. Workers at greater risk of heat stress include those who are 65 years of age or older, are overweight, have heart disease or high blood pressure, or take medications that may be affected by extreme heat.
Prevention of heat stress in workers is important. Understanding heat stress can help prevent it. Here are some things we can all do:
 be aware of the signs and symptoms of heat stress  drink plenty of water or electrolyte balanced fluids like Gatorade, even before you feel thirsty  dress properly, this includes a light colored shirt  stay in shape  take breaks to cool down – if possible, save heavy work for mornings and evenings when it’s cooler  avoid alcohol, caffeine or carbonated beverages which can cause dehydration  avoid hot, heavy meals  avoid salt tablets – they may worsen fluid imbalance
Operating Companies should provide training to workers so they understand what heat stress is, how it affects their health and safety, and how it can be prevented.
The next several pages explain the various types of heat related illnesses; the most serious is Heat Stroke. Heat Stroke is a true medical emergency and requires prompt medical attention.
Most persons will progress through the stages of heat related illness, starting with heat cramps which if unchecked will progress to heat syncope, heat exhaustion and up to and including heat stroke. Which is why, employees must understand the preventable measures to take as well as the early symptoms of heat related illness and appropriate first aid measures.
Soaking their clothes with water. Spraying, sponging, or showering them with water. Fanning their body.

Types of Heat Stress

Heat Stroke
Heat stroke is the most serious heat-related disorder. It occurs when the body becomes unable to control its temperature: the body’s temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. When heat stroke occurs, the body temperature can rise to 106 degrees Fahrenheit or higher within 10 to 15 minutes. Heat stroke can cause death or permanent disability if emergency treatment is not given.
Symptoms of heat stroke include: •    Hot, dry skin or profuse sweating •    Hallucinations •    Chills •    Throbbing headache •    High body temperature •    Confusion/dizziness •    Slurred speech
First Aid Take the following steps to treat a worker with heat stroke:
•    Call 911 and notify their supervisor. •    Move the sick worker to a cool shaded area. •    Cool the worker using methods such as:
Heat Exhaustion
Heat exhaustion is the body’s response to an excessive loss of the water and salt, usually through excessive sweating. Workers most prone to heat exhaustion are those that are elderly, have high blood pressure, and those working in a hot environment.
Symptoms of heat exhaustion include: •    Heavy sweating •    Extreme weakness or fatigue •    Dizziness, confusion
•    Nausea •    Clammy, moist skin •    Pale or flushed complexion •    Muscle cramps •    Slightly elevated body temperature •    Fast and shallow breathing
First Aid Treat a worker suffering from heat exhaustion with the following:
•    Have them rest in a cool, shaded or air-conditioned area. •    Have them drink plenty of water or other cool, nonalcoholic beverages. •    Have them take a cool shower, bath, or sponge bath.
Heat Syncope
Heat syncope is a fainting (syncope) episode or dizziness that usually occurs with prolonged standing or sudden rising from a sitting or lying position. Factors that may contribute to heat syncope include dehydration and lack of acclimatization.
Symptoms of heat syncope include:

Light-headedness Dizziness Fainting
First Aid Workers with heat syncope should:
•    Sit or lie down in a cool place when they begin to feel symptoms. •    Slowly drink water, clear juice, or a sports beverage.
Heat Cramps
Heat cramps usually affect workers who sweat a lot during strenuous activity. This sweating depletes the body’s salt and moisture levels. Low salt levels in muscles causes painful cramps. Heat cramps may also be a symptom of heat exhaustion.
Symptoms of heat cramps include; Muscle pain or spasms usually in the abdomen, arms, or legs.
First Aid Workers with heat cramps should:
•    Stop all activity, and sit in a cool place. •    Drink clear juice or a sports beverage. •    Do not return to strenuous work for a few hours after the cramps subside because further exertion may
lead to heat exhaustion or heat stroke. •    Seek medical attention if any of the following apply:

The worker has heart problems. The worker is on a low-sodium diet. The cramps do not subside within one hour.
Heat Rash
Heat rash is a skin irritation caused by excessive sweating during hot, humid weather.
Symptoms of heat rash include:
•    Heat rash looks like a red cluster of pimples or small blisters. •    It is more likely to occur on the neck and upper chest, in the groin, under the breasts, and in elbow
creases. First Aid
Workers experiencing heat rash should:

Try to work in a cooler, less humid environment when possible. Keep the affected area dry. Dusting powder may be used to increase comfort.

Recommendations for Employers Employers should take the following steps to protect workers from heat stress:

•    Schedule maintenance and repair jobs in hot areas for cooler months. •    Schedule hot jobs for the cooler part of the day. •    Acclimatize workers by exposing them for progressively longer periods to hot work environments. •    Reduce the physical demands of workers. •    Use relief workers or assign extra workers for physically demanding jobs. •    Provide cool water or liquids to workers.
o    Avoid alcohol, and drinks with large amounts of caffeine or sugar. •    Provide rest periods with water breaks. •    Provide cool areas for use during break periods. •    Monitor workers who are at risk of heat stress. •    Provide heat stress training that includes information about:
o    Worker risk o Prevention o Symptoms o    The importance of monitoring yourself and coworkers for symptoms o Treatment
o    Personal protective equipment Recommendations for Workers
Workers should avoid exposure to extreme heat, sun exposure, and high humidity when possible. When these exposures cannot be avoided, workers should take the following steps to prevent heat stress:
•    Wear light-colored, loose-fitting, breathable clothing such as cotton. o    Avoid non-breathing synthetic clothing.
•    Gradually build up to heavy work. •    Schedule heavy work during the coolest parts of day. •    Take more breaks in extreme heat and humidity.
o    Take breaks in the shade or a cool area when possible. •    Drink water frequently. Drink enough water that you never become thirsty. Approximately 1 cup every
15-20 minutes. •    Avoid alcohol, and drinks with large amounts of caffeine or sugar. •    Be aware that protective clothing or personal protective equipment may increase the risk of heat stress. •    Monitor your physical condition and that of your coworkers.
