    Although the findings of the incidents differ, they all have common factors, bad weather and strong winds.

  • What did they learn?

    Emphasise the importance of reviewing the weather reports and including weather in toolbox talks (TBT).

    Continuously monitor the weather and communicate any changes to those who may be affected.

    Conduct thorough routine drops inspections, especially before and after bad weather.

    Always be vigilant - guard against complacency whilst completing routine tasks.

    Consider the effect of weather on all your activities, equipment and potential dropped objects.

  • Ask yourself or your crew

    What are your experiences with bad weather on site?

    • What equipment has been affected?
    • Have there been any injuries to workers?

    What is your normal inspection regime? Does it change according to weather conditions?

    What is your communication like on site? If a situation changed quickly, how effective are your channels of communication?
