Preventing Heat Injury

As summer heats up, heat can affect workers’ health and slow production. Heat illnesses like heat exhaustion and heat stroke (see our June 24 post) are serious and can even be life-threatening. Fortunately precautions can be taken to prevent heat injury by following these suggestions from the Centers for Disease Control:

  • Reduce the physical demands of the job by using powered equipment to perform heavy tasks. DJ Products powered carts and movers are the perfect solution to take the strain off workers when materials, equipment, products or supplies must be moved from one place to another. Ergonomic design eliminates muscle strain, fatigue and physical stress, protecting the health and safety of your workers. Our battery powered CartCaddies do the heavy labor so your workers don’t overexert themselves in the heat.
  • Wear loose clothing to promote air flow and a hat to shield yourself from the sun. When uniforms must be worn, natural-fiber, breathable fabrics like cotton provide better management of body heat. Certain newer fabrics are available that help wick sweat away from the body, keeping the body cooler in summer and warmer in winter.
  • Decrease work exposure or, when exposure cannot be avoided, the length of exposure to high heat and humidity. Shorten shifts for high exposure jobs or rotate tasks to decrease exposure periods.
  • Use fans to decrease humidity and increase air speed to allow maximum evaporative cooling from sweating.
  • Provide shade in work areas where possible and certainly in break areas.
  • Drink plenty of fluids and replenish salt and minerals lost during sweating. This is why sports figures drink Gatorade and similar beverages that contain salt and minerals. Salty snacks at break times can also help. Water should be continually available to workers during periods of high heat and humidity, and a worker’s request for water should not be denied.

Worker complaints about feeling ill or dizzy when temperatures soar should not be taken lightly. Cool water (sipped slowly); a break in a cool, air conditioned room; and application of cool, wet cloths to the skin will help. But anyone who complains should be carefully watched for additional signs of heat illness. Be aware that some medications exacerbate the effects of heat on the body, a possible side effect about which many people are unaware. If a heat injury victim does not respond to basic first aid, if vomiting occurs, the person loses consciousness, or if his body temperature continues to rise and sweating ceases, call 911 or get the victim to a hospital immediately.

Help Workers Beat the Heat

The dog days of August aren’t here yet but the nationwide heat wave means it’s time to review heat safety tips to prevent heat exhaustion and heat stroke. When workers don’t work in temperature controlled environments, heat can take a toll on workers’ health, cause production to suffer and even be life-threatening when workers and managers do not take proper precautions to manage heat stress.

Sweat is the body’s cooling system. As air passes over the body, it evaporates sweat, cooling the body. But during hot weather, particularly if the humidity is high, sweating can’t keep up. Body temperature rises faster than sweating can cool it down. When body temperatures get too hot, heat illness and even death can occur. Older, overweight and pregnant workers are most at risk of heat illnesses, which include:

  • Heat rash where the skin becomes irritated from excessive sweating. Tightly fitting clothing can exacerbate heat rash and the individual’s discomfort.
  • Heat cramps are painful muscle pains or spasms, generally in the abdomen and legs, brought on by exertion or exercise during prolonged exposure to high temperatures. Heat cramps are often the first sign that the body is not coping with high temperatures.
  • Heat exhaustion occurs when body fluids are lost through heavy sweating and not replaced. In an effort to cool the body, blood flow to the skin is increased, drawing it away from vital organs and causing mild shock. Heat exhaustion is evidenced by extreme lethargy, heavy sweating, rapid breathing and a fast, weak pulse. If not treated, it can lead to dangerous heat stroke.
  • Heat stroke (also called sun stroke) is a life-threatening condition indicating that the body’s natural cooling mechanism has completely broken down and ceased functioning. Body temperatures can rise above 106 degrees Fahrenheit, high enough to cause brain damage. Sweating stops and the skin becomes dry to the touch. The individual’s pulse begins to race, becoming strong and rapid. Heat stroke victims can become dizzy, particularly dangerous if they are operating equipment. If untreated, unconsciousness, permanent brain damage and death can follow.
