With much of the nation in the grip of an arctic blast, many construction sites are shut down. Others, with the aid of new technologies -- like chemical additives that allow concrete to cure in low temperatures – may continue to operate, exposing workers to extreme weather.
The Center for Construction Research and Training (CPWR) is reminding employers and workers that extended exposure to freezing or cold temperatures can result in health problems such as trench foot, frostbite and hypothermia. "Danger signs include uncontrolled shivering, slurred speech, clumsy movements, fatigue, and confused behavior," according to Executive Director Pete Stafford.
