Table O.4.3 shows a fluid intake requirement of more than 1.2 litres per hour for heavy O.4.3.6 work. At high workloads and/or thermal stress, sweat rates exceed 1.2 litres per hour. Increasing fluid intake much above this level is not practicable due to gastric discomfort, as the upper limit for gastric emptying and fluid absorption is 1.5 litres per hour. Therefore, control measures to improve thermal conditions should be implemented, in addition to providing adequate hydration to replace lost sweat.© IRATA International Annex O Page 27 of 45 2017-Aug-01Interventions (NB No rope access technician to work alone)Rehydration schedule (per hour)Work/rest schedule (minutes)Low risk unrestricted zone TWL: 140 to <220No limits on self-paced workLight work: 600 ml to 1 litreSafe for all continuous self- paced workCautionary zone indicates situations in which environmental conditions require additional precautions.Light work: 1 to 1.2 litresSafe for continuous self- paced light work
