With the winter upon us, workers and their employers should begin considering the risks and hazards of working is a cold environment. Those workers who regularly work outdoors for extended periods of time, such as snow cleanup crews, sanitation workers, police officers and emergency response and recovery personnel, are at a nominal risk for experiencing cold stress.
Compiled from the U.S. Department of Labor Occupational Safety and Health Administration’s website, we’d like to share some FAQ’s, tips and information to prevent cold stress during this imminent winter weather.
How cold is too cold?
Extreme cold and its effects ultimately vary across different areas of the country; in regions that are not used to winter weather, near freezing temperatures are considered “extreme cold.” When the temperatures dip too low, the body is forced to work harder to maintain its temperature. Additionally, colder-than-normal temperatures can cause body heat to leave the body more rapidly. Wind chill is the temperature your body feels when air temperature and wind speed are combined. For example, when the air temperature is 40°F, and the wind speed is 35 mph, the effect on the exposed skin is as if the air temperature was 28°F.
Cold stress occurs by driving down the skin temperature and eventually the internal body temperature (core temperature). This drastic change can easily lead to serious health problems including serious tissue damage and even death.
What are the risk factors that contribute to cold stress?
Some of the risk factors that contribute to cold stress are: wetness or dampness, dressing improperly, and exhaustion. Additionally predisposing health conditions such as hypertension, hypothyroidism, diabetes and poor physical conditioning increase a person’s risk for cold stress.
