Increasing air temperatures as a result of climate change are worsening the impact of heat exposure on working populations, including mining workers, who are at risk of suffering heat-related illnesses, injury and death. However, inadequate awareness of climate change-related occupational heat stress risks and adaptation strategies have been shown to render occupational heat stress management ineffective. A concurrent mixed-methods approach was used to assess the perceptions of climate change and occupational heat stress risks and adaptation strategies of mining workers among supervisory personnel and other stakeholders in Ghana. Questionnaires and interviews were used to elicit data from 19 respondents. Data were processed and interpreted using descriptive statistics, chi-square and Fisher's exact tests, and thematic analysis. Supervisors' climate change risks perception was adequate, and their concern about workplace heat exposure risks was moderate. Mining workers' occupational heat stress risks experiences were linked to heat-related illness and minor injuries. Mining workers' adaptation strategies included water intake, use of cooling mechanisms, work-break practices, and clothing use. The related differences in job experience in the distribution of climate change risk perception and occupational heat stress risk experiences, and the difference in educational attainment in the distribution of adaptation strategies of occupational heat stress were significant (p < 0.05). Hence, an effective workplace heat management policy requires adequate understanding of occupational heat stress risks and adaptation policies and continued education and training for mining workers.
气候变化导致的空气温度升高,正在加剧高温暴露对工作人群的影响,包括矿工,他们面临与热相关的疾病、伤害和死亡的风险。然而,人们对与气候变化相关的职业热应激风险和适应策略的认识不足,使得职业热应激管理无效。本研究采用混合方法同步评估加纳监管人员和其他利益相关者对矿工的气候变化和职业热应激风险及适应策略的看法。采用问卷和访谈从 19 名受访者中收集数据。使用描述性统计、卡方和 Fisher 精确检验以及主题分析处理和解释数据。主管人员对气候变化风险的认识是充分的,他们对工作场所热暴露风险的关注是适度的。矿工的职业热应激风险经历与与热相关的疾病和轻伤有关。矿工的适应策略包括摄入水分、使用冷却机制、工作中断实践和穿着适当的衣服。在气候变化风险认知和职业热应激风险经历的分布上,工作经验的差异,以及在职业热应激适应策略的分布上,教育程度的差异具有统计学意义(p<0.05)。因此,有效的工作场所热管理政策需要充分了解职业热应激风险和适应政策,并对矿工进行持续的教育和培训。
