Firefighters are known to be exposed to a wide variety of combustion products during operational and training firefighting activities. However, the potential for exposure to diesel exhaust emissions, recently classified as carcinogenic to humans by the International Agency for Research on Cancer, also exists within the fire station environment. In this study, concentrations of diesel particulate matter and polycyclic aromatic hydrocarbons have been measured in the engine bays, duty offices and dormitory areas of eight fire stations in Queensland, Australia. Operation of fire appliances and mechanical equipment during start of shift checks were found to contribute more strongly to overall engine bay diesel particulate matter concentrations than the number of fire appliance departures and returns. Polycyclic aromatic hydrocarbons were found to be transported further into fire station living environments than diesel particulate matter. This study highlights a number of potential strategies for reducing firefighter exposures to components of diesel engine exhaust in the fire station environment.

消防站中的柴油颗粒物和多环芳烃

众所周知，消防员在进行操作和训练消防活动时会接触多种燃烧产物。但是，消防局的环境中也存在暴露于柴油机废气中的潜在危险，最近被国际癌症研究机构归类为对人类有致癌作用。在这项研究中，已经测量了澳大利亚昆士兰州八个消防站的发动机舱，值班室和宿舍区中的柴油颗粒物和多环芳烃的浓度。发现在换班检查开始时消防设备和机械设备的操作对整体发动机舱柴油颗粒物浓度的贡献比消防设备起降次数更大。据发现，多环芳烃比柴油机颗粒物质更能输送到消防局的生活环境中。这项研究重点介绍了减少消防员在消防局环境中暴露于柴油机排气成分的多种潜在策略。
