Abstract

Marching band (MB) artists are subject to exertional heat illnesses (EHIs) similar to other active groups like laborers and athletes. Yet, they are an understudied population with no evidence-based heat safety guidelines. Presented here is a case study of the 233rd annual Bristol, RI Independence Day Parade in 2018 that resulted in over 50 EHIs, including 25 from the Saint Anthony Village marching band (MB) from suburban Minneapolis, MN. This research aims to identify the contributing factors that led to the large number of EHIs, as well as guide ensuring the safety of MB artists in future events. A human heat balance model in conjunction with local weather data was used to simulate heat stress on MB artists. Three modeling scenarios were used to isolate the roles of clothing (band uniform vs. t-shirt and shorts), weather (July 4, 2018 vs. 30-year climatology), and metabolic rate (slow, moderate, and brisk marching pacing) on heat stress. The results identify several key factors that increased heat stress. The meteorological conditions were unusually hot, humid, and sunny for Bristol, resulting in reduced cooling from evaporation and convection, and increased radiant heating. Behavioral factors also affect heat stress. The full marching band uniforms reduced evaporative cooling by 50% and the activity levels of marching 4 km over several hours without breaks resulted in conditions that were uncompensable. Finally, it is speculated that a lack of acclimatization for participants from cooler regions may have exacerbated heat-related impacts. These findings highlight several recommendations for MB directors and race organizers, including the use of summer uniforms for anticipated hot conditions, and advance parade planning that includes providing shade/hydration before and after the parade for participants, considering cooler routes that reduce radiant heating and preparing for anticipated heat-related health impacts appropriate for anticipated hot conditions.

游行安全与规划:行进乐队艺术家的热平衡案例研究。
与劳动者和运动员等其他活跃群体相似,军乐队(MB)艺术家也会患上劳累性高温病(EHIs)。然而,他们是一个研究不足的群体,没有基于证据的高温安全指南。本文介绍的是一项关于 2018 年第 233 届俄勒冈州布里斯托尔独立日游行的案例研究,该游行导致 50 多人出现 EHI,其中包括来自明尼苏达州明尼阿波利斯市郊圣安东尼村军乐队(MB)的 25 人。这项研究旨在找出导致大量 EHI 的诱因,并为确保 MB 艺术家在未来活动中的安全提供指导。人体热平衡模型与当地天气数据相结合,用于模拟 MB 艺术家的热应力。使用了三种建模场景来区分服装(乐队制服与 T 恤和短裤)、天气(2018 年 7 月 4 日与 30 年气候)和新陈代谢率(慢速、中速和快速行进步伐)对热应力的作用。结果确定了增加热应激的几个关键因素。布里斯托尔的气象条件异常炎热、潮湿和晴朗,导致蒸发和对流产生的冷却减少,辐射热增加。行为因素也会影响热应力。全套的军乐队制服使蒸发冷却减少了 50%,而几个小时不间断地行进 4 公里的活动量导致了无法补偿的状况。最后,据推测,来自凉爽地区的参赛者缺乏适应性,可能会加剧与热有关的影响。这些研究结果强调了对医疗保险指导人员和比赛组织者的几项建议,包括在预计的炎热条件下使用夏季制服,提前进行游行规划,包括在游行前后为参与者提供遮阳/补水,考虑凉爽的路线以减少辐射热,以及为预计的炎热条件下与热有关的健康影响做好适当的准备。

期刊介绍: The Journal of Occupational and Environmental Hygiene ( JOEH ) is a joint publication of the American Industrial Hygiene Association (AIHA®) and ACGIH®. The JOEH is a peer-reviewed journal devoted to enhancing the knowledge and practice of occupational and environmental hygiene and safety by widely disseminating research articles and applied studies of the highest quality. The JOEH provides a written medium for the communication of ideas, methods, processes, and research in core and emerging areas of occupational and environmental hygiene. Core domains include, but are not limited to: exposure assessment, control strategies, ergonomics, and risk analysis. Emerging domains include, but are not limited to: sensor technology, emergency preparedness and response, changing workforce, and management and analysis of "big" data.
