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<0.05). Mining workers are vulnerable to the hazards of heat exposure which can endanger their health and safety, productive capacity, social well-being, adaptive capacity and resilience. An evaluation of indoor and outdoor Wet Bulb Globe Temperature (WBGT) in the working and living environment showed that mining workers can be exposed to relatively high thermal load, thus raising their heat stress risk. Adequate adaptation policies and heat exposure management for workers are imperative to reduce heat stress risk, and improve productive capacity and the social health of mining workers.

估计加纳采矿工人与热暴露相关的严重程度和风险。

许多位于户外阳光直射下的职业环境(例如露天采矿)由于暴露在高温下的工作量增加而对工人的健康、安全和生产力构成风险。气候变化的影响、工作的物理性质、延长轮班工作的要求以及穿着限制蒸发冷却的防护服的需要加剧了这个问题。尽管加纳拥有大量劳动力的快速扩张的采矿业,但似乎没有研究评估过采矿工人暴露在高温下的程度和风险及其对这些劳动力的潜在影响。问卷和温度数据记录器用于评估加纳矿工工作和生活环境中暴露于高温的风险和程度。不同性别工人的热暴露风险因素的差异,教育水平、工作量、工作时间、体力劳动和与热源的接近程度显着(p<0.05)。采矿工人容易受到高温危害,这可能危及他们的健康和安全、生产能力、社会福祉、适应能力和复原力。对工作和生活环境中的室内外湿球温度(WBGT)的评估表明,采矿工人可能会暴露在相对较高的热负荷下,从而增加他们的热应激风险。为工人制定充分的适应政策和热暴露管理对于降低热应激风险、提高生产能力和采矿工人的社会健康至关重要。采矿工人容易受到高温危害,这可能危及他们的健康和安全、生产能力、社会福祉、适应能力和复原力。对工作和生活环境中的室内外湿球温度(WBGT)的评估表明,采矿工人可能会暴露在相对较高的热负荷下,从而增加他们的热应激风险。为工人制定充分的适应政策和热暴露管理对于降低热应激风险、提高生产能力和采矿工人的社会健康至关重要。采矿工人容易受到高温危害,这可能危及他们的健康和安全、生产能力、社会福祉、适应能力和复原力。对工作和生活环境中的室内外湿球温度(WBGT)的评估表明,采矿工人可能会暴露在相对较高的热负荷下,从而增加他们的热应激风险。为工人制定充分的适应政策和热暴露管理对于降低热应激风险、提高生产能力和采矿工人的社会健康至关重要。对工作和生活环境中的室内外湿球温度(WBGT)的评估表明,采矿工人可能会暴露在相对较高的热负荷下,从而增加他们的热应激风险。为工人制定充分的适应政策和热暴露管理对于降低热应激风险、提高生产能力和采矿工人的社会健康至关重要。对工作和生活环境中的室内外湿球温度(WBGT)的评估表明,采矿工人可能会暴露在相对较高的热负荷下,从而增加他们的热应激风险。为工人制定充分的适应政策和热暴露管理对于降低热应激风险、提高生产能力和采矿工人的社会健康至关重要。
