Ventilation is an obvious COVID-19 control but could be a bugger to use

Vaccines are currently the most effective tool available to minimise the spread of COVID-19 to large populations. Fortunately, effective vaccines have been able to be manufactured at such a rapid pace. But previous pandemics have not had vaccines and have had to rely, primarily, on hygiene and isolation. Part of the hygiene practice was to ensure that buildings were well-ventilated. Ventilation actions on COVID-19 were part of Europe’s response to the pandemic in 2020, but Australia has only just started to accept the need for improved ventilation as it was very late to the risks of aerosol transmission.

As vaccinated workers return to workplaces in many of Australia’s urban centres, employers will need to assess their occupational health and safety (OHS) duties in new ways, and ventilation will be a significant challenge.

More OHS information on Midfield Meats

Recently The Monthly magazine took a close look at the labour practices of Midfield Meats (paywalled), a major Warrnambool company and meat exporter that had been, yet again, successfully prosecuted by WorkSafe Victoria. There are workplace safety elements to The Monthly’s story that were not as prominent as other issues and there were some questions for companies and governments that have supported Midfield in the past.

Australia gets serious on psychological health at work

Below is an article written by Carlo Caponecchia and published originally on May 25 2021. Caponecchia is a leading figure in workplace psychological hazards and strategies. The article is reproduced with permission.


Employers are about to ramp up their efforts to protect mental health at work.

Last week, workplace health and safety (WHS) ministers from around Australia agreed to changes that will formalise what’s expected of employers in relation to mental health in Regulation. 

These changes respond to a review of the model WHS laws by Marie Boland, former Executive director at Safework South Australia. The model WHS laws are a “blueprint” used since 2011 to make safety laws more consistent across the States and Territories.

Resilience = the enemy of the Duty of Care

Last year Professor Michael Quinlan and Dr Elsa Underhill wrote about how precarious work arrangements had contributed to the spread and prevalence of COVI19 in Australia and its workplaces. Soon Australia’s Treasurer, Josh Frydenburg, will announce his 2021-22 Budget strategy. It is forecast to include big government spending and in many different areas of Australian industry, but the economy and Australians’ health may be better served by addressing the precarious employment structures on which more and more businesses rely and about which the Government seems disinterested.

In the latest edition of Griffith Review (no. 72), Angela Smith looked at how embedded precarious work is in Australia’s economic rebound. She also looked at how the wellbeing and wellness industries compound the health and safety risks of this type of work in this time of COVID19.

Change in the air on ventilation

One of Edward O’Donoghue’s recent Motion supporters in Victoria’s Parliament was Georgie Crozier, the Liberal Opposition’s Shadow Health Minister. In her speech in support of the Motion, she mentioned ventilation:

“I have been asking for the audits of what has occurred in hotel quarantine under the new structure that the government put in after that catastrophic failure of last year. They said, ‘The system’s fixed; everything is fine. We’ve got processes in place and it’s safe’. Well, it is not safe. I have been wanting to see those ventilation audits, see those safety audits, look at the issues that are arising here, because the other states are not having the same degree of breaches and problems and terrible consequences that we are in Victoria. So something is going wrong; something is going terribly wrong. It is the Andrews government that has to take responsibility for this. It is an absolute outrage that they continue to not take responsibility for this.”

Hansard, Page 24

Until recently, Australia was reluctant to accept the spread of COVID19 by air. The focus was on droplets and the cleanliness of surfaces. An aerosolised coronavirus’s risk was, until very late last year, a fringe risk – one not substantiated by evidence.

Business voices add weight to OHS change

On February 27 2012, The Australian reprinted/tweaked a Harvard Business Review (HBR) article on Burnout. A significant feature of the article is the acknowledgement of organisational factors as contributing to burnout and other workplace mental health hazards. The situation seems to have changed as these types of acknowledgements were harder to draw out of psychological health experts when SafetyAtWorkBlog spoke to some in 2019.

However, there are also clear parallels to Australian research into job stressors that could have helped HBR’s author Dave Lievens add weight to the decades-long research of Michael Leiter and Christina Maslach.

Building a resilient society

In the middle of a pandemic, it is easy to be locked into small issues, especially if they directly relate to you, such as lockdowns or sick relatives but it is important to be reminded of the broader social context. Professor Michael Quinlan recently wrote an editorial for the Annals of Work Exposures and Health, entitled “COVID-19, Health and Vulnerable Societies”.
