n� CDIM Corporate Safety Program "` HSP-10. Heat and Cold Stress Management ENGINEERING Rev. 0 5/21/2020 4.2 Cold Stress Safety Procedures The combination of low temperature, wind speed, and humidity can create cold conditions that may lead to frostbite, hypothermia, and death (Table 6-3). Hypothermia is often caused by exposure to cold weather or immersion in cold water. Primary treatments for hypothermia are methods to warm the body back to a normal temperature. The procedures provided in this section will be used to mitigate the hazards of cold weather. • Cold weather safety will be a "tailgate" safety meeting subject every day the temperature is below 36°F. Signs of frostbite and hypothermia and the appropriate use of clothing will be reviewed at those meetings. • Workers will use the"buddy system" anytime work conditions fall below 36°F. • Workers who become immersed in water at air temperatures below 360F shall be immediately provided with a change of clothing and treated for hypothermia. • Eyewear providing protection against ultraviolet light, glare, and blowing ice crystals will be worn in snow and/or ice covered terrain. • If wind chill is a factor at a work location, the cooling effect of the wind shall be reduced by shielding the work area or providing workers with an outer windbreak garment. • Individuals showing signs of frostbite or hypothermia will be kept warm and be immediately transported to the nearest medical facility. • Workers shall be excluded from work in cold (30°F or below) if they are suffering from diseases or taking medication that interferes with body temperature regulation or reduces tolerance to cold weather conditions. • Warm-up breaks of at least ten minutes each will be scheduled at the time interval noted in Table 6-4, Cold Weather Warm-up Break Schedule. Table 5-4. Signs and Symptoms of Cold Stress Frostbite is frozen tissue. Stages leading to frostbite include: • reddened skin • blanched skin • white, gray, or bluish skin Hypothermia is dangerously reduced body temperature. Stages leading to hypothermia include: • shivering • shivering cessation • lethargy, confusion, loss of coordination • decreased vital signs • apparent death Page 8 of 9
