nnovative <br /> onstructlon <br /> olutions <br /> Thermal Stress Monitoring <br /> When permeable work clothes are worn ( street clothes or clothing ensembles over street <br /> clothes ) , physiological monitoring may be required . Regularly observe workers for signs and <br /> symptoms of heat stress and implement physiological monitoring as indicated below . This should <br /> start when the heat index reaches 80F ( 27C ) [ see Heat Index Table below] , or sooner if workers <br /> exhibit symptoms of heat stress indicated in the table above . These heat index values were <br /> devised for shady, light wind conditions ; exposure to full sunshine can increase the values by up <br /> to 15 ° F ( 80C ) . Also , strong winds, particularly with very hot, dry air, can be extremely hazardous . <br /> � 4E " ' " f9 National Weather Service <br /> Y T Heat Index Chart <br /> � C <br /> id Temperature ( ° F) <br /> 80 82 84 86 88 90 92 94 96 98 100 102 104 106 108 110 <br /> 40 80 81 83 85 88 91 94 97 101 105 109 114 119 124 <br /> 45 80 82 84 87 89 93 96 100 104 109 114 119 124 f1 <br /> 50 81 83 85 88 91 95 99 103 108 113 118 124 131 137 <br /> 55 81 84 86 89 93 97 101 106 112 117 124 [130 137 <br /> v <br /> 60 82 84 88 91 95 100 105 110 116 123 129 137 <br /> 5 65 82 85 89 93 98 103 108 114 121 128 136 <br /> = 70 83 86 90 95 100 105 112 119 6 134 <br /> m <br /> �- 75 84 88 92 97 103 109 116 124 2 <br /> 80 84 89 94 100 106 113 121 <br /> 85 85 90 96 102 110 117 <br /> 90 86 91 98 105 113 122 <br /> 95 86 93 100 108 117 <br /> 100 87 95 103 112 121 <br /> Likelihood of Heat Disorders with Prolonged Exposure and/or Strenuous Activity <br /> Caution Extreme CautionD Danger ■ Extreme Danger <br /> Heat Index Possible Heat Disorders Minimum Frequency of <br /> physiological Monitoring <br /> 80OF - 90 ° F Fatigue possible with prolonged Observe Workers for signs <br /> ( 27 ° C - 32 ° C ) exposure and /or physical activity of heat stress and <br /> implement physiological <br /> monitoring if warranted . <br /> Sunstroke , heat cramps , or heat Every 2 hours , or sooner, if <br /> 90 ° F - 1050F exhaustion possible with signs of heat stress are <br /> ( 320C - 410C ) prolonged exposure and /or observed . <br /> physical activity <br /> 23 <br />
