Cold Stress : 

Cold Stress Identifying and Responding to Cold Exposure Hazards

COLD STRESS FACTORS : 

2 COLD STRESS FACTORS Temperature of the air surrounding the body Body temperature Air movement around the body Body movement Length of exposure

COLD ENVIRONMENT : 

3 COLD ENVIRONMENT Normal body temperature 98.6º F Body temperature drops below 86º, control system becomes ineffective Below 59º, body begins to experience impairment of many functions Most hypothermia results when ambient temperature is between 30º and 40º F

COLD ENVIRONMENT : 

4 COLD ENVIRONMENT Increased heat loss to the environment Muscle hypertonus, resulting in shivering, is body’s attempt to maintain body temperature

HYPOTHERMIA : 

5 HYPOTHERMIA Prolonged exposure to cold causes the body to lose energy faster than it is produced Body temperature drops to lower than normal Can happen when temperatures are above freezing

CONDITIONS AFFECTING HYPOTHERMIA : 

6 CONDITIONS AFFECTING HYPOTHERMIA Aging, allergies, poor circulation, and illness Self-imposed conditions, such as drinking, smoking, and taking sedatives also increase risks Wet clothing, windy conditions, and poor physical condition

HYPOTHERMIA SYMPTOMS : 

7 HYPOTHERMIA SYMPTOMS Numbness, stiffness, drowsiness, poor coordination Slow or irregular breathing and heart rate Slurred speech Cool skin, and puffiness in the face are common

HYPOTHERMIA SYMPTOMS : 

8 HYPOTHERMIA SYMPTOMS May seem apathetic about getting out of cold Shivering and teeth chattering is a sure sign that body temperature is too low Victim first feels cold then may feel mild pain in extremities

HYPOTHERMIA SYMPTOMS : 

9 HYPOTHERMIA SYMPTOMS Victim may seem confused and disoriented with memory lapses Worst-case can be death

SAFETY PROCEDURES : 

10 SAFETY PROCEDURES Get victim to where it is warm Get them out of wet, frozen, or tight clothing Keep victim dry Get them into loose warm clothes or blankets Give warm (room temperature) liquids

SAFETY PROCEDURES : 

11 SAFETY PROCEDURES Do not give alcohol or substances containing caffeine Warm center of body first If necessary, seek medical assistance and give CPR

FROSTBITE : 

12 FROSTBITE Most serious, and second most common, cold exposure hazard Nose, ears, cheeks, fingers, and toes most often affected Affected area doesn’t get enough heat and freezes

FROSTBITE : 

13 FROSTBITE Freezing causes blood vessel constriction Results in lack of oxygen, excess fluid buildup, blistering, and tissue death May not be aware anything bad is happening

FROSTBITE : 

14 FROSTBITE Recognized by distinct pallor of the exposed skin Skin goes from white or grayish yellow, to reddish violet, to black Usual feeling of being really cold, then numb May get a tingling or aching feeling or brief pain

FROSTBITE : 

15 FROSTBITE Damage to skin sometimes causes blisters Constricted blood vessels impair blood flow Can cause permanent tissue damage

FROSTBITE : 

16 FROSTBITE Victim can become unconscious Death may result from heart failure If necessary, seek medical assistance and give CPR

CARE OF FROSTBITE : 

17 CARE OF FROSTBITE Don’t rub the affected part Don’t use hot baths, or heat producing devices Don’t break blisters

CARE OF FROSTBITE : 

18 CARE OF FROSTBITE Warm the frozen part with clothing, blankets, or with room temperature water Once warm, exercise the affected parts Exception: Do not walk on frostbitten feet

DRIVING EMERGENCY PREPAREDNESS : 

19 DRIVING EMERGENCY PREPAREDNESS Serviceable clothing (sweatshirt, jeans, coveralls, coat) Distilled water and anti-freeze Easily stored, nonperishable food (chips, candy bars, cookies, some canned foods, etc.)

DRIVING EMERGENCY PREPAREDNESS : 

20 DRIVING EMERGENCY PREPAREDNESS Matches, in a waterproof container Large candles Tool kit (pliers, screwdrivers, crescent wrench, jumper cables, duct tape, electrician’s tape, etc.)

21 A couple quarts of motor oil and multipurpose lubricant, such as WD 40 Ice scraper, sand or kitty litter, traction mat, shovel DRIVING EMERGENCY PREPAREDNESS

DRIVING EMERGENCY PREPAREDNESS : 

22 Road atlas Reflective triangles or flares Several blankets or comforters DRIVING EMERGENCY PREPAREDNESS

BE PREPARED FOR ADRIVING EMERGENCY : 

23 BE PREPARED FOR ADRIVING EMERGENCY Keep a healthy respect for your safety in cold weather !! AND A cellular phone!!

PROTECTION : 

24 PROTECTION Prevention is the best way to deal with cold stress Don’t drink alcohol, bathe, smoke, or take drugs before being exposed to cold Dress in loose layers of dry clothing

PROTECTION : 

25 PROTECTION Cover hands, feet, face, and head Keep moving Take regular breaks in warm places
