Presentation Transcript

  1. April 2013 CNG Competitor Analysis Heat Stress: California

  2. Hot Work Environments • Outdoor work in hot weather • Foundry work or smelting • Brick-firing, ceramics, or glass manufacture • Rubber manufacture • Work in bakeries, confectioneries, kitchens • Laundry operations 1a

  3. Personal Risk Factors • Age, weight, physical fitness • Metabolism, medications, alcohol or drugs • Water and caffeine consumption • Acclimatization 2a

  4. Environmental Risk Factors • Air temperature • Humidity • Radiant heat • Conductive heat sources • Protective clothing • PPE 2b

  5. Fatigue • Blood circulates to upper layers of skin • Less blood for internal organs • Performance declines • Coordination and alertness decline Response to Fatigue • Rest in cool, shaded area for 5 minutes • Take heat-relief breaks • Gradually adjust to working in heat 3a

  6. Heat Rash • Results from the body’s natural cooling • Body releases heat through sweat • Sweat ducts become plugged • Skin inflammation develops • Prickly rash is uncomfortable • Rash can become infected Response to Heat Rash • Rest in a cool area • Wash the skin • Allow skin to dry • Seek medical attention, if infected • Regularly bathe and dry skin 4a

  7. Fainting • Blood accumulates in lower part of body • Brain does not get adequate blood supply • Sudden loss of consciousness Response to Fainting • Rest in cool, shaded area for 5 minutes • Gradually adjust to working in heat • Move around to circulate blood 5a

  8. Muscle Cramps + Occurs in tired muscles when the worker sweats profusely and drinks large quantities of water • Painful contractions in the muscle • Uncomfortable and temporarily disabling • Low salt level can cause spasms • Too much salt can cause cramps 6a

  9. Response to Muscle Cramps • Rest in cool, shaded area for 5 minutes • Drink small quantities of water frequently • Drink up to 4 cups per hour • Avoid caffeinated beverages or alcohol • Drink salted or carbohydrate replacement liquids for recovery • Gradually adjust to working in heat 6c

  10. Heat Exhaustion • Large amounts of fluid lost by sweating • Symptoms resemble early heat stroke • Physically weak, fatigued, or faint • Giddy, irritable, or mentally confused • Nauseous • Headache, dizziness, and/or lightheadedness • Person continues to sweat • Skin is clammy and moist • Body temperature remains normal • Person may vomit or lose consciousness 7a

  11. Response to Heat Exhaustion • Rest in shade for 5 minutes minimum • Drink plenty of fluids • Seek medical attention, if severe 7c

  12. Heat Stroke • Life-threatening condition • Body’s temperature regulatory system fails • Sweating becomes inadequate • Person’s skin is hot and dry • Skin appears red in color • Body temperature is 103oF or higher • Person is mentally confused or delirious • Person can have convulsions or become unconscious 8a

  13. Response to Heat Stroke • Get immediate medical attention • Remove to cool, shaded area • Soak clothing with cool water • Fan body vigorously • Never leave unattended 8c

  14. What Can You Do? • + Report symptoms or signs immediately • + Respond to heat illness • + Continuously monitor the weather to stay informed and take the appropriate actions. 8d

  15. Measuring Heat Exposures • Heat index system • Health and safety agency testing 9a

  16. Measuring Heat Exposures + Work classifications: • Light hand work • Heavy hand work • Hand work would be just that – only using your hands. Typically something along the lines of assembly work, line work, etc. • Heavy work with one arm • Light work with two arms • Working with the arms would be things like Pushing, Pulling, Lifting with your arms, etc. • Moderate work with the body • Heavy work with the body • This work would be all of the above plus Bending, Twisting, Turing, Carrying, Lifting with your legs, Working with Protective Suits, etc. • The greater the exertion and strain on your body combined with the higher temps, the quicker the effects of heat has on your body. 9b

  17. Controlling Heat Exposure + Engineering controls • Shade • Ventilation • Air cooling • Air circulation • Shielding from radiant heat sources • Insulating radiant heat sources • Use of power assists and tools 10a

  18. Controlling Heat Exposure + Personal protective equipment • Ice vests • Water-cooled garments • Air supply systems • Wet clothing, headbands, or bandanas 10b

  19. Controlling Heat Exposure + Work practices • Use intermittent rest periods • Ensure access to water • Drink small quantities of water frequently • Use relief workers • Use the buddy system • Pace the work • Reduce physical demands • Provide cool recovery or shaded rest areas • Schedule work for cooler times of the day • Wear light, loose-fitting, breathable clothing 10c
