Farmworkers who harvest and weed field crops are at increased risk for heat exposure and heat-related illness (HRI). The study objectives were to: (1) train crew leaders to use the Occupational Safety and Health Administration (OSHA) heat safety tool app and evaluate the utility of the app from a crew leader perspective; and (2) characterize heat safety knowledge, preventive practices, and perceptions of HRI risk among Hispanic farmworkers. Before harvest season, six crew leaders completed a 2-hour OSHA heat illness prevention training, including evaluation of a heat safety mobile app. Between August and October 2018, 101 Hispanic farmworkers participated in cross-sectional surveys about heat safety. Survey participants responded to questions about HRI prevention, HRI knowledge, and sociodemographics. Crew leaders using the heat safety app rated the app very highly on relevance, functionality, value and privacy. Farmworkers did not report being overly concerned about HRI based on their survey responses. Nevertheless, 19% of farmworkers had experienced nonspecific symptoms from working in the heat, such as headache, dizziness, and nausea. In the multivariate linear regression model, farmworkers had lower heat safety knowledge scores if they were H-2A visa holders, female, and only "a little bit concerned," compared to others who were "very concerned" about working in the heat. The results of this study indicate the need for continued heat safety training for both crew leaders and farmworkers to reduce the risk of HRI, especially among less experienced farmworkers.
收割和除草田间作物的农场工人面临更高的热暴露和热相关疾病（HRI）风险。本研究的目的是：（1）培训组长使用职业安全与健康管理局（OSHA）的热安全工具应用程序，并从组长的角度评估该应用程序的实用性；（2）描述西班牙裔农场工人的热安全知识、预防措施以及对HRI风险的认知。在收获季节之前，六名组长完成了为期两小时的OSHA热疾病预防培训，包括对一款热安全移动应用程序的评估。在2018年8月至10月期间，101名西班牙裔农场工人参与了关于热安全的横断面调查。调查参与者回答了有关HRI预防、HRI知识和社会人口统计学的问题。使用热安全应用程序的组长对该应用程序在相关性、功能、价值和隐私方面给予了高度评价。根据调查回复，农场工人并未报告对HRI过度担忧。然而，19%的农场工人曾因在高温环境下工作而出现非特异性症状，如头痛、头晕和恶心。在多元线性回归模型中，与那些对在高温环境下工作“非常担忧”的其他人相比，持有H - 2A签证、女性且只是“有点担忧”的农场工人热安全知识得分较低。本研究结果表明，需要继续对组长和农场工人进行热安全培训，以降低HRI风险，尤其是在经验较少的农场工人中。
