Indoor firing ranges are a source of lead exposure and elevated blood lead levels (BLLs) among employees, their families, and customers, despite public health outreach efforts and comprehensive guidelines for controlling occupational lead exposure. There are approximately 16,000-18,000 indoor firing ranges in the United States, with tens of thousands of employees. Approximately 1 million law enforcement officers train on indoor ranges. To estimate how many adults had elevated BLLs (≥10 µg/dL) as a result of exposure to lead from shooting firearms, data on elevated BLLs from the Adult Blood Lead Epidemiology and Surveillance (ABLES) program managed by CDC's National Institute for Occupational Safety and Health (NIOSH) were examined by source of lead exposure. During 2002-2012, a total of 2,056 persons employed in the categories "police protection" and "other amusement and recreation industries (including firing ranges)" had elevated BLLs reported to ABLES; an additional 2,673 persons had non-work-related BLLs likely attributable to target shooting. To identify deficiencies at two indoor firing ranges linked to elevated BLLs, the Washington State Division of Occupational Safety and Health (WaDOSH) and NIOSH conducted investigations in 2012 and 2013, respectively. The WaDOSH investigation found a failure to conduct personal exposure and biologic monitoring for lead and also found dry sweeping of lead-containing dust. The NIOSH investigation found serious deficiencies in ventilation, housekeeping, and medical surveillance. Public health officials and clinicians should ask about occupations and hobbies that might involve lead when evaluating findings of elevated BLLs. Interventions for reducing lead exposure in firing ranges include using lead-free bullets, improving ventilation, and using wet mopping or high-efficiency particulate air (HEPA) vacuuming to clean.
室内射击场是员工、员工家属和顾客接触铅和血铅水平升高(BLL)的一个来源,尽管公共卫生部门做了大量宣传工作,并制定了全面的职业性铅接触控制指南。美国大约有 16000-18000 家室内射击场,有数万名员工。大约有 100 万执法人员在室内靶场接受培训。为了估计有多少成年人因射击枪支而接触铅导致 BLL 升高(≥10μg/dL),美国疾病控制与预防中心(CDC)国家职业安全与健康研究所(NIOSH)管理的成人血铅流行病学和监测(ABLES)计划中,BLL 升高的数据按铅暴露源进行了分析。2002-2012 年期间,共有 2056 名在“警察保护”和“其他娱乐和休闲行业(包括射击场)”类别中就业的人向 ABLES 报告了 BLL 升高;另有 2673 人因靶场射击而可能与非工作相关的 BLL 升高。为了确定与 BLL 升高相关的两家室内射击场的缺陷,华盛顿州职业安全与健康部(WaDOSH)和 NIOSH 分别于 2012 年和 2013 年进行了调查。WaDOSH 的调查发现,没有对铅进行个人接触和生物监测,也没有发现含铅粉尘的干式清扫。NIOSH 的调查发现通风、卫生和医疗监测方面存在严重缺陷。公共卫生官员和临床医生在评估 BLL 升高的发现时,应询问可能涉及铅的职业和爱好。减少射击场铅暴露的干预措施包括使用无铅弹、改善通风以及湿式拖地或高效微粒空气(HEPA)吸尘。
