    Episode 71:
    Bushfires and Respiratory Protection - Part 1.

    In this episode, Terry Gorman, 3M’s Lead Application Engineer for the Personal Safety Division in Australia and New Zealand joins host Mark Reggers for the first of a two-part series to discuss bushfires and respiratory protection.

    Bushfire smoke generates a gigantic volatile cocktail of hydrocarbons of various sizes, shapes and toxicity. Measuring the degree of respiratory hazard exposure from bushfire smoke is never easy as there are many factors at play during the blaze. Respiratory protection in these unpredictable conditions is critical, which, when used correctly and paired to the circumstances, can significantly reduce your exposure.

    • What is a P2 mask, and why is it recommended for bushfire smoke?
    • What is an N95 filter and is that suitable for bushfire smoke? How is this different from a P2?
    • What should people be aware of if they are wearing a disposable mask?
    • Why does the Australian standard say that if you are wearing a P3 filter on a half face mask to treat it as a P2 protection factor?
    • Are there other masks or filters that would be recommended to capture some of the gases that bush firefighters would potentially be exposed to at the fire front?

    Bushfires are an ongoing concern, as summer rolls around the threats become ever-present, to what extent however we don’t know. Preparation is essential and applies to residents in the bushfire zone, firefighters and volunteers on the front line, and the general public. When fires rage across the country do you know how to protect yourself in the course of the inferno and in the aftermath, during cleanup operations? Tune in as we cover the topic of bushfires and respiratory protection to ensure you are ready and have the correct gear to protect yourself, your family and those in need around you.
