It is almost impossible for occupational health and safety (OHS) people to stop looking at the world through the risk assessment parameters and hierarchies with which they work every day. The Hierarchy of Control could be applied to the COVID19 pandemic with the important lesson that the elimination of a hazard does not only come from the right purchase but could require months and months of a combination of Administrative Controls, Personal Protective Equipment, and perseverance. This impossibility should not be something that makes OHS professionals shy. It should be embraced and expanded, where possible, beyond the bounds of workplace organisations to societal design and change.
Michael Quinlan has recently written about a different investigative process that could be directly applied to the management of disasters, including COVID19. His research on Ten Pathways to Death and Disaster has been popping up in conferences, books and public speaking, including the OHS advocacy of Dr Gerry Ayers of the CFMEU, and has rarely been more timely.
