Heat Illness Safety Tips for Outdoor Employees

Employers have a critical responsibility to ensure the safety of their workers from various hazards, including those related to heat. High temperatures, especially when paired with strenuous physical activities, can elevate a worker’s body temperature to dangerous levels. Normally, the body cools itself through sweating, but in hot and humid conditions, this mechanism may not suffice, leading to serious heat illnesses. These conditions include:

Types of Heat Illnesses:

1. Heat Rash: This skin irritation is caused by sweat not evaporating from the skin.
2. Heat Cramps: Painful muscle spasms, often affecting the arms, legs, or abdomen.
3. Heat Exhaustion: A more severe condition caused by excessive loss of body salts and fluids through sweating. Symptoms include headache, nausea, vomiting, dizziness, lightheadedness, weakness, intense thirst, rapid heartbeat, irritability, heavy sweating, and cool, moist skin.
4. Heat Stroke: The most critical heat-related illness, potentially fatal. It occurs when the body can no longer regulate its temperature. Symptoms include confusion, rapid heart rate, fainting, unconsciousness, high body temperature, seizures, excessive or no sweating, and skin that is red, hot, dry, or damp.

Factors Increasing Risk of Heat Illness

Several factors can heighten the risk of heat illness, including age, poor diet, obesity, dehydration, lack of physical fitness, certain medical conditions (e.g., schizophrenia, heart or lung disease), and specific medications (e.g., vasoconstrictors, diuretics, antidepressants, stimulants, antipsychotics).

Implementing Heat Safety Policies

To protect workers, employers should develop and enforce comprehensive heat safety policies. Key strategies include:

1. Appropriate Clothing: Workers should wear loose, light-colored clothing and a hat or hard hat when safe.
2. Scheduled Breaks: Regular breaks in the shade, with the removal of outer protective gear, are essential.
3. Gradual Acclimatization: Gradually increasing the intensity of work helps workers adjust to hot conditions, essential during the first week.
4. Avoiding Overexertion: Workers should avoid intense physical activity during peak temperature times.
5. Hydration: Regular drinking of fluids, even without thirst, is crucial. Avoid sugary drinks, caffeine, and alcohol. Cold drinks should be consumed cautiously to prevent stomach cramps.
6. Sunscreen Use: Applying sunscreen prevents sunburn and further heat stress.
7. Diet: Light meals are preferable to avoid adding internal heat.

Responding to Heat Illnesses

Employers must be prepared to act quickly if a worker shows signs of heat illness. Here’s what to do for each condition:

1. Heat Rash: Keep the area dry and shift the worker to a cooler, less humid environment.
2. Heat Cramps: Move the worker to a shaded, cool area, encourage rest and hydration, and seek medical attention if cramps persist.
3. Heat Exhaustion: Move the worker to a shaded, cool area. They should lie down with their legs elevated. Loosen or remove clothing and apply ice packs, cold compresses, or wet towels. Provide cool water and ensure the worker does not return to work that day. Follow up with a medical exam if symptoms do not improve or worsen.
4. Heat Stroke: This is a medical emergency. Call an ambulance immediately. While waiting, move the worker to a cool, shaded area, loosen clothing, fan them if the heat index is below the high 90s Fahrenheit, and apply ice packs, and cold compresses, or immerse them in cool water. Ensure they remain hydrated if conscious, and do not leave them alone. Call the hospital for further instructions if medical help is delayed.
