Occupational heat stress
A quantitative job-exposure matrix (JEM) for occupational heat stress providing estimates of annual hours of wet bulb globe temperature (WBGT) reference value exceedance by job, geographical region and year between 1970 and 2023.
The JEM has been developed based on historic climate data from the European Centre for Medium Range Weather Forecasts following guidelines and standards set by the International Organization for Standardization (ISO 7243, 8996 and 9920) for heat stress assessment.
