Researchers at the National Institute for Occupational Safety and Health (NIOSH) are conducting mine illumination research with the objective of improving miner safety. Slips, trips, and falls (STFs) are the second leading accident class (18.1%, n = 2,374) of nonfatal lost-time injuries at underground mines (MSHA, 2005-2009). Factors contributing to STFs include recognition of hazards as well as postural balance and age. Improved lighting may enable better hazard recognition and reduce the impact of postural balance and age. Previous research has shown that cap lamp technology that used light-emitting diodes (LEDs) has improved hazard detection. This study was an initial investigation to determine if cap lamp lighting significantly influences measures of static postural stability (displacement and velocity of center of pressure). Results of this investigation showed no significant differences in the balance measures of interest between cap lamps tested. However, balance was shown to significantly decline (p < 0.05) when tested in an underground coal mine compared to the laboratory testing condition. Relevance to industry: Underground coal mine workers wear cap lamps on their hard hats as their primary light source to illuminate nearby areas where their vision is directed. Proper illumination may improve miner safety by improving their STF hazard recognition and balance.

帽灯照明对姿势控制和稳定性的影响

美国国家职业安全与健康研究所 (NIOSH) 的研究人员正在进行矿井照明研究，旨在提高矿工安全。滑倒、绊倒和跌倒 (STF) 是地下矿山非致命失时伤害的第二大事故类别（18.1%，n = 2,374）（MSHA，2005-2009）。造成 STF 的因素包括对危险的认识以及姿势平衡和年龄。改进的照明可以更好地识别危险并减少姿势平衡和年龄的影响。先前的研究表明，使用发光二极管 (LED) 的帽灯技术可以改善危险检测。本研究是一项初步调查，旨在确定头灯照明是否显着影响静态姿势稳定性（压力中心的位移和速度）的测量。这项调查的结果表明，所测试的帽灯之间的平衡测量没有显着差异。然而，与实验室测试条件相比，在地下煤矿进行测试时，平衡性显着下降（p < 0.05）。与行业的相关性：地下煤矿工人在安全帽上佩戴帽灯作为主要光源，照亮其视线所指向的附近区域。适当的照明可以通过提高矿工对 STF 危险的识别和平衡来提高他们的安全性。
