Nunfam, V. F., Adusei-Asante, K., Van Etten, E. J., Frimpong, K., & Oosthuizen, J. (2021). Estimating the magnitude and risk associated with heat exposure among Ghanaian mining workers. International Journal of Biometeorology. Advance online publication.


Many occupational settings located outdoors in direct sun, such as open cut mining, pose a health, safety, and productivity risk to workers because of their increased exposure to heat. This issue is exacerbated by climate change effects, the physical nature of the work, the requirement to work extended shifts and the need to wear protective clothing which restricts evaporative cooling. Though Ghana has a rapidly expanding mining sector with a large workforce, there appears to be no study that has assessed the magnitude and risk of heat exposure on mining workers and its potential impact on this workforce. Questionnaires and temperature data loggers were used to assess the risk and extent of heat exposure in the working and living environments of Ghanaian miners. The variation in heat exposure risk factors across workers’ gender, education level, workload, work hours, physical work exertion and proximity to heat sources is significant (p
