What is the maximum workload percentage an experienced worker should handle by the third day in a heat wave?

In the context of heat exposure and ensuring worker safety, acclimatization to high temperatures is a crucial factor. After an initial period of exposure to heat, workers should gradually increase their workload to allow their bodies to adapt. Research and guidelines suggest that experienced workers can handle up to 80% of their normal workload by the third day of acclimatization during a heat wave. This gradual increase helps avoid heat-related illnesses, as it gives the body time to adjust to the stress of the heat.

By the end of the third day, if workers have been properly acclimatized and the conditions are not excessively extreme, it is generally considered acceptable for them to operate at this increased level of workload. However, it is important that this increase takes into account individual factors such as recent heat exposure, hydration levels, and overall health conditions. The choice of 80% for the maximum workload is aligned with health and safety guidelines aimed at preventing heat stress.
