The suggested frequency of physical monitoring for fit and acclimatized workers is presented below. <br /> ren.9 Tj m a •- a a g : - - 0 10 <br /> 90°F (32.2°C) After each 45 minutes of Work After each 15 minutes or Work <br /> Or above <br /> 87.5-90°F After each 60 minutes of Work After each 30 minutes of Work <br /> 30.8-32.2°C <br /> 82.5-87.5°F After each 90 minutes of Work After each 60 minutes of Work <br /> 28.1-30.8°C <br /> 77.5-82.5°F After each 120 minutes of Work After each 90 minutes of Work <br /> 25.3-28.1°C <br /> 72.5-77.5°F After each 150 minutes of Work After each 120 minutes of Work <br /> 22.5-25.3°C <br /> A normal work ensemble consists of cotton coveralls or other cotton clothing with long sleeves and pants. <br /> Calculate the adjusted air temperature (ta adj) by using this equation: to adj F=ta F+ (13x% sunshine). <br /> Measure air temperature (ta) with a standard mercury in-glass thermometer, with the bulb shielded from <br /> radiant heat. Estimate percent sunshine by judging what percentage of time the sun is not covered by <br /> clouds thick enough to produce a shadow. (100 percent sunshine = no cloud cover and a sharp, distinct <br /> shadow; 0 percent sunshine = no shadows). <br /> ® HEAT INDEX - 900-1000 <br /> Sunstroke, heat cramps, and heat exhaustion are possible with prolonged exposure and physical activity. <br /> • HEAT INDEX - 1050 - 1290 <br /> Sunstroke, heat cramps and heat exhaustion likely. Heatstroke possible with prolonged exposure and <br /> physical activity. <br /> • HEAT INDEX 1300 or Higher <br /> Heatstroke or sunstroke imminent. <br /> Safety/Personal Protective Equipment: <br /> The following PPE will be available to be used as needed. <br /> Eye Protection -ANSI Approved Safety Glasses <br /> Respiratory Protection -dust masks <br /> Hand Protection - Gloves <br /> Head Protection — Hard Hat <br /> Foot Protection —Steel Toe Shoes <br /> Protective Clothing —Coveralls and Tyvek Suits <br /> Confined Space Safety Equipment <br /> **Level C available as needed*** <br />
