Cold Weather Safety - When winter is locked in around us, OSHA and other experts offers tips on things an employer can do to protect workers from cold weather. But given that you can’t monitor everyone all the time, there’s only so much the organization can do in any safety situation. In the end, the responsibility for safety always falls on the individual worker. --Understand the risks of cold weather. Among the most serious are frostbite and hypothermia. --Know when these threats may be affecting you. For frostbite, that means feeling cold, then numb, with tingling, aching or brief pain. Frostbitten skin also may appear white or grayish, and may blister. Hypothermia is signaled by chills, shivering, and feelings of drowsiness and confusion.
