Cold stress can be prevented, and the best way to do so is to avoid exposure to extreme conditions and monitor the crew’s physical condition during tasks in the cold.
As with anything in life, preparation is the key. You should train your employees before extreme weather conditions hit your course, and have a defined contingency plan for cold weather.
You also need to be aware of what is too cold, and how that standard may vary based on your location and factors related to the individual. Any time when temperature drops significantly and wind speeds increase, you need to evaluate the situation and take wind chill into consideration. Due to wind chill, the temperature your body feels could be much colder than the actual temperature out. If the temperature is 40F, for example, and wind speeds are at 35mph, the body would feel a temperature of 28F. If you use a weather app on your phone, pay attention to the “feels like” temperature.
