1. 1 Weather Extremes and Heat Illness Training

2. 2 Employees must not work under dangerous weather conditions. However, if proper precautions are taken, and with your supervisors approval, you may work in weather that is part of the study design or is made safe with precautions and specialized equipment. The following slides list precautions, equipment and the law related to heat illness and other weather dangers. Weather Extremes

3. 3 WEATHER PRECAUTION/EQUIPMENT NEEDED Heat Take precautions to avoid heat stroke, heat cramps and heat exhaustion; drink ample fluids, wear loose clothing, wear a hat, limit time working while wearing gear that does not breathe or when working in areas with poor ventilation. Avoid working during the hottest part of the day. Cold Dress appropriately for cold or rainy weather. If working in a remote location, bring blankets or sleeping bag in case you are unable to return by nightfall. Weather Extremes Chart from IIPP (Section 6.4)

4. 4 WEATHER PRECAUTION/EQUIPMENT NEEDED Rain Advance preparation for stuck vehicles, such as carrying a cell phone and using a vehicle that is four-wheel drive or equipped with a winch is recommended. Listen to the radio for flooding alerts. High winds Employees should avoid driving in high winds and protect eyes and lungs from dust. Fog Avoid driving in dense fog. If zero visibility, pull well off the road, park, and turn lights off. Give advance warning to motorists when working along roadsides in foggy weather (discussed in 6.11 of IILP). Weather Extremes Chart from IIPP

5. 5 WEATHER PRECAUTION/EQUIPMENT NEEDED Dust To protect eyes and lungs, employees are encouraged to wear eye protection such as goggles, and respiratory protection with a filtering face piece or other appropriate or required respiratory protection when working in dusty conditions. (See RPP) Lightning Employees should not work in dangerous lightning conditions. Weather Extremes Chart from IIPP

6. 6 Weather Extremes: Clothing Disposable clothing, rubber boots, and gloves retain heat and moisture and can contribute to heat-related illnesses. Make sure that the DPR rules and the law is followed for heat illness prevention. Disposable clothing, rubber boots, and gloves retain heat and moisture and can contribute to heat-related illnesses. Make sure that the DPR rules and the law is followed for heat illness prevention. Conversely, the same clothing can provide protection from cold weather.

When wearing disposable coveralls, the general rule of thumb is to have at least one layer of clothing on to provide some protection if your coveralls tear or need to be changed in the field.

7. 7 Heat Illness Education

8. 8 Heat Stroke-The most serious health problem for workers in hot environments is caused by the failure of the body's ability to regulate its core temperature. Heat Exhaustion-Results from loss of fluid through sweating when a worker has failed to drink enough fluids, salt or both. Heat Rash- or prickly heat may happen when sweat is not easily removed from skin by evaporation. Heat Cramps- painful Spasms of muscles. Fainting or Heat syncope- may be caused by a worker who is not acclimated to a hot environment. Heat Illness (HI) Types

9. 9 Warning signs of Heat Exhaustion Heavy sweating Heavy sweating Paleness Paleness Muscle cramps, Weakness Muscle cramps, Weakness Dizziness and or Headache Dizziness and or Headache Nausea or vomiting Nausea or vomiting Fainting Fainting What to do Cool victim as for heat stroke, to avoid progression to heat stroke. Cool victim as for heat stroke, to avoid progression to heat stroke. Heat Exhaustion Signs and Action

10. 10 Heat Stroke Heat stroke occurs when the body becomes unable to control its temperature: the bodys temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. Body temperature can rise to 106°F or higher, within 10-15 minutes. Heat stroke can cause death or permanent disability if emergency treatment is not given.

11. 11 Warning signs of heat stroke vary but may include: Extremely high body temp (above 103°F orally) Extremely high body temp (above 103°F orally) Red, hot, and dry skin (no sweating) Red, hot, and dry skin (no sweating) Rapid, strong pulse Rapid, strong pulse Throbbing headache Throbbing headache Dizziness Dizziness Nausea Nausea Confusion Confusion Unconsciousness Unconsciousness Heat Stroke Signs

12. 12 What to do If you see the signs of heat stroke, you are dealing with a life threatening emergency. Call for assistance and begin to cool the victim: If you see the signs of heat stroke, you are dealing with a life threatening emergency. Call for assistance and begin to cool the victim: Get the person in the shade Get the person in the shade Cool the person rapidly using what ever methods you can (wrap wet towel, use sample ice etc.) Cool the person rapidly using what ever methods you can (wrap wet towel, use sample ice etc.) Monitor body temperature Monitor body temperature Drink fluid, non-alcohol, non-caffeine Drink fluid, non-alcohol, non-caffeine Get medical help ASAP, call 911 Get medical help ASAP, call 911 Heat Stroke Action

13. 13 Note: Not an official DPR recommended way to cool off (probably works though).

14. 14 Heat Illness and the Law According to the Heat Illness Prevention Standard in Title 8, CCR Section 3395: Employers must provide HI training. Employers must provide HI training. Provide enough fresh water, at least 1 quart per hour per employee and employers must encourage consumption of fluids.
