Cold Weather

Prolonged exposure to cold, wet and windy conditions, even when the temperatures are above freezing, can be dangerous. Extreme cold conditions exist when the equivalent (wind) chill temperature is at or below -25° F (-32 °C). Wind chill temperature is a function of the actual temperature and the estimated wind speed. Under windless conditions, air provides an invisible blanket around the skin. As wind speed increases, this layer of heated air is carried away from the body at an accelerated rate resulting in apparent temperatures well below the air temperature

When working in cold weather, employers and workers should take simple precautions, such as those listed below:

Wear several layers of clothing rather than one thick Layer.

Wear gloves and a warm hat or a helmet liner under the hard hat.

Wear synthetic or cotton clothing next to the skin to control sweat.

Wear warm footwear with one or two pairs of warm socks; footwear should not fit too tightly because it will restrict blood flow and cause more harm than good.

Wear a scarf or face mask in cold windy weather.

Take frequent short breaks in a warm shelter to allow the body to warm up.

 Avoid exhaustion or fatigue because energy is needed to keep muscles warm.

 Drink warm, sweet beverages and avoid drinks with caffeine or alcohol.

Eat warm, high calorie food such as pasta dishes.

Workers who take certain medications, are in poor physical condition or suffer from illnesses such as diabetes, high blood pressure, or cardiovascular disease are at increased risk and should therefore check with a doctor for additional advice.
