Unlike systemic hypothermia, frostbite rarely occurs unless the ambient temperatures are less than treezing and usually less than 200F Symptoms of frostbite are: a sudden olancning or whiterung of the sxin; the � skin has a waxy or white appearance ana is firm to the touch; tissues are cold, pale, and solid. Prevention of Cold Related Illness - Educate workers to recognize the svmntoms of frostbite ana hvpothermia Identify ana limit known risk factors- Assure the availability of enclosea, heatea environment on or adjacent to the site. • Assure the availability of dry changes of clothing. • Develop the capability for temperature recording at the site. • Assure the availability of warm drinks. Monitoring - i - Start (oral) temperature recording a the job site • At the Field Team L,eaaer s discretion when suspicion is bases on changes in a worker's performance or mental status • At a worker s request. • As a screening measure, two tithes oer shift, under unusually hazardous conditions (e.g., wind-chill less than 20OF car wind-cht1I less than 30°F with precipitation) ' As a screening measure whenever any one worker on the site develops hypothermia. Any person devetooing moderate hvpotnerrnia (a core temperature of 92°F) cannot return to work for 48 hours 1 EJS/sY=-D i/0= 2-S
