The respiratory protection options that are being provided to volunteer firefighters by the NSW Rural Fire Service are very limited and could impact upon firefighter health.
The simple fact that firefighters are raising concerns on social media and other platforms is reason enough to investigate further.
Concentrations of CO and fine particulate matter in fire zones commonly exceed the short-term occupational health standards and can be between 100 and 1000-fold higher than ambient air quality standards. Indeed, CO concentrations exceeding 300 parts per million and fine particulate matter concentrations of 100 micrograms per cubic metre (µg/m³) are common around bushfires.
