Diesel particulate matter and polycyclic aromatic hydrocarbons in fire stations
2017
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.
