Introduction
Working in high heat conditions, whether outdoors under the blazing sun or inside a sweltering factory, can put enormous strain on our bodies. Without proper precautions, the heat we generate combined with external temperatures can interfere with the body’s natural cooling processes and lead to heat stress and related illnesses.
This article will teach you how to recognize, prevent and treat potentially dangerous heat-related conditions. The information presented here is drawn from an online workplace training course focusing on heat stress awareness and safety. Follow these tips to keep yourself and coworkers cool, healthy and safe during hot summer months or in year-round hot work environments.
How Heat Affects the Body
It’s normal for physical exertion on the job to make us hot and sweaty. But excessive heat poses health risks by disrupting the body’s ability to cool itself down. Our circulatory system and sweat glands work in tandem to regulate our internal temperature:
- Blood circulation directs warm blood to the surface of the skin, where it releases heat before cycling back through the body to collect more. This “pumps” heat out.
- Sweating produces an additional cooling effect through evaporative cooling as sweat evaporates off the skin.
However, sweating leads to dehydration as huge volumes of water and electrolytes are lost. Workers can sweat out up to a quart per hour under extreme conditions. Dangerous electrolyte imbalances and fluid loss manifest in conditions like heat cramps, heat exhaustion and heat stroke. That’s why proper hydration is absolutely critical for working in heat.
Recognizing Heat Stress and Heat-Related Illnesses
Our cooling systems can become overwhelmed in hot environments leading to heat stress. Ignoring early symptoms can allow less serious heat issues to spiral into medical emergencies:
- Heat Syncope: Inadequate blood/oxygen flow to the brain from blood being diverted to the skin. Symptoms include dizziness, fainting, and rapid heartbeat.
- Heat Cramps: Painful muscle spasms and cramps resulting from electrolyte imbalances from heavy sweating. Often occurs in legs, arms, and abdomen.
- Heat Exhaustion: More severe reaction caused by extreme fluid and electrolyte loss. Characterized by heavy sweating, intense thirst, weakness, dizziness, rapid pulse, and cool, pale skin.
- Heat Stroke: The most serious heat illness. The body loses all ability to regulate temperature leading to an uncontrolled spike. Symptoms include throbbing headache, nausea/vomiting, disorientation, seizure, extremely high body temperature, and loss of consciousness. Requires emergency medical treatment.
Treating Heat-Related Illnesses
If a coworker experiences a heat-related health episode, immediate first aid can prevent worsening. Response steps include:
- Moving them to a shaded, cooler area. Have them sit or lie down to rest.
- Loosen or remove heavy, tight, dark clothing and provide access to moving air from fans or ventilation.
- Cool victim down by applying cold compresses, ice packs, wet towels, or cooling garments like vests.
- Give them access to cool drinking water or electrolyte beverages.
- Monitor symptoms closely. Seek emergency medical attention if symptoms are severe or you suspect heat stroke.
Preventing Heat Stress
Planning ahead and taking preventative measures can help you avoid heat illnesses in hot work environments:
- Acclimate: Gradually increase work hours in hot conditions over 5-10 days to allow your body to adjust. Those in good physical shape acclimate more quickly.
- Hydrate: Drink 5-7 ounces of fluids every 15-20 minutes. Water and sports drinks replenish critical electrolytes. Avoid alcohol and caffeine.
- Dress Light: Wear loose, breathable, light colored clothing. Cotton, moisture-wicking and mesh fabrics help maximize air flow and cooling effects of sweating.
- Block Sun: Use sunscreen and wear hats, sunglasses and UV protective clothing when working in the sun.
- Schedule Work Carefully: Plan the most physically intense work during the coolest parts of day and provide additional breaks for rest and hydration.
- Use Engineering Controls: Take advantage of climate control systems, local exhaust ventilation, cooling fans, shielding, and other heat-reducing equipment modifications.
- Know Limitations: Certain medications, health conditions, and age can increase vulnerability to heat illnesses. Some workers face higher risk and may need tailored accommodations.
