Lead levels at a new indoor target shooting range were assessed using both personal and environmental air monitoring methods. Surface swabs were collected from representative locations throughout the range prior to, and at the conclusion of, shooting. Personal samples were compared against the current Australian Workplace Exposure Standards with all results exceeding statutory limits. Static environmental samples exceeded the Air National Environmental Protection Measures (NEPM) air quality standard. Surface swabs showed significant increases from pre- to post-shooting with levels exceeding recommended limits. The performance of the mechanical ventilation system was also assessed and airflow levels were below the required rate at all test locations when compared against the values recommended by the National Institute for Occupational Safety and Health (NIOSH). Users of the indoor shooting range are at risk of potential exposure to hazardous levels of lead. It was recommended the ventilation system be reviewed by a suitably qualified ventilation engineer to ensure it is operating within the required parameters and able to transport generated lead contaminant away from the shooters breathing zone. A thorough cleaning regime should be implemented by the club to minimise surface lead loadings throughout the facility.
采用个人和环境空气监测方法对新的室内射击场的铅含量进行了评估。在射击前后，从整个射击场的代表性位置采集了表面拭子。个人样本与当前澳大利亚工作场所暴露标准进行了比较，所有结果均超过法定限值。静态环境样本超过了国家环境保护措施（NEPM）空气质量标准。表面拭子显示出从射击前到射击后的显著增加，其水平超过了推荐限值。还对机械通风系统的性能进行了评估，与美国国家职业安全与健康研究所（NIOSH）建议的值相比，所有测试位置的气流水平均低于所需速率。室内射击场的使用者有接触危险水平铅的潜在风险。建议由合格的通风工程师对通风系统进行审查，以确保其在所需参数内运行，并能够将产生的铅污染物从射击者的呼吸区运走。俱乐部应实施彻底的清洁制度，以尽量减少整个设施表面的铅负荷。
