Cold Safety Critical

Safety should be Priority One when your dealership staff is working outside in the cold.

Despite cold temperatures, the activity of winter work may fuel a false sense of protection against cold weather hazards. If unprepared, laborers can be numbed into serious cold stress injuries, including hypothermia, frostbite and trench foot, says Tamela Brown, environmental health and safety officer with Ohio State University’s Ohio Agricultural Research and Development Center.

"Planning for work in cold weather is the most important defense. Be aware of how the body reacts to cold and wear appropriate clothing. Proper insulation and good ventilation is critical," says Brown.

Some of the more common cold stress injuries are:

  • Hypothermia: Hypothermia literally means “low heat” and develops when body heat is lost faster than it is replaced. Symptoms range from shivering, slurred speech, memory loss, pale or cold skin, confusion, severe muscle stiffness, loss of consciousness, and death. "Temperatures do not have to be below freezing for hypothermia to occur, especially in vulnerable individuals," says Brown. "Older adults can develop low body temperatures after exposure to a mild cold which would only produce discomfort in younger people." Proper treatment depends on the severity of the hypothermia. With mild cases (body temperature of 98–90 degrees Fahrenheit), move to a warm area, replace any wet clothes, cover the head, and drink warm (not hot), non-alcoholic liquids. For more severe cases, call 911 for an ambulance and cover all extremities completely.
  • Frostbite: Frostbite occurs when skin temperature drops and blood flow to the surface of the skin decreases as the blood vessels constrict. The fluid in the cells and tissues begins to form ice crystals. Frostbite typically affects the extremities, particularly the feet and hands. Symptoms include cold, stinging, or achy feelings in the frostbitten area, followed by numbness. The skin turns red, then purple, then white or very pale and is cold to the touch. If these symptoms occur, call 911. Do not rub the affected area and wrap it in soft cloth.
  • Trench foot: Also known as immersion foot, trench foot develops when the feet are cold, damp, and confined in constricted footwear. It is similar to frostbite and can also result in gangrene and amputation. Trench foot can result in swelling, tingling, itching, loss of skin, or skin ulcers. If these conditions develop, soak feet in warm water, then wrap with dry cloth bandages, and consume warm, non-alcoholic drinks.

Brown says that cold stress injuries are avoidable if the proper precautions are taken.

"Employers can help protect workers from cold stress by providing training, controlling temperature, and wind with heaters and windbreaks if possible, and rotating workers in cold jobs," says Brown. She also recommends scheduling work at the warmest times, providing extra breaks as necessary, establishing a buddy system, and keeping first aid supplies and equipment available.
