Note: Work intensity relates to a worker’s metabolic rate (Watts). Light intensity (200W) includes standing or sitting office work, Moderate (300W) walking and lifting light objects, Heavy (400W) lifting or shovelling labour, e.g. agricultural work.
The data displayed on this page are based on the climate projections specified in YourArea Tomorrow, specifically the 2-model (GFDL and UKesm) midpoint and the Socio-Economic-Pathway 370. The statistical methods for calculating Unsafe Work Days are based on the ISO Standard 7243. The WBGTmax thresholds assigned to work intensities and the metabolic rates assumed for calculating productivity loss using the Kjellstrom/Lemke risk curve based on the Sahu/Wyndham epidemiological studies are given below:
Light work (200W metabolic rate): 31.1°C / 88°F
Moderate work (300W metabolic rate): 28.8°C / 83.8°F
Heavy work (400W metabolic rate): 27.2°C / 81°F
