Chill factor

Wind chill

The rate of heat loss from exposed skin due to the combined effects of wind and cold is defined as "wind chill." This concept takes into account both temperature and wind speed to determine how cold it actually feels compared to the actual air temperature. When wind flows over the skin, it removes heat from the body more quickly than still air, leading to an increased sensation of cold, which can greatly affect health and safety, especially in cold weather conditions.

Understanding wind chill is essential for construction supervisors and workers, as it helps to assess the risks of hypothermia and frostbite in cold environments. By considering both wind and temperature, individuals can make informed decisions about appropriate clothing and work practices to protect themselves from extreme weather conditions.
