Learning from our Peers: COVID-19 Prevention Approaches and Protections for Essential Workers across the Country and around the World 

UPDATE: Videos now available here!

* Please complete our short survey following the webinar here.

The reluctance of WHO, CDC, and equivalent health authorities globally to recognize aerosol transmission of SARS CoV-2 has often led to inadequate protection of essential workers and marginalized the role of industrial hygienists and other occupational health professionals in the response. How can we take the lessons from the pandemic to influence worker protection from SARS-CoV-2 and prepare for future aerosol infectious disease outbreaks and pandemics? Consideration of a permanent standard that drives both “preparedness” and “prevention” for future variants of concern (VOC) and future pandemics is warranted and will be discussed (building on the July 2020 Occ-COVID session “Assessing the impact of Cal/OSHA’s Aerosol Transmissible Disease Standards”).

In addition, this session will leverage leading international practices to “go beyond” public health measures with a focus on essential workers, including the critical role of worker training at every stage of re-opening.

Face Coverings & Respirators - Filling the Gaps

Friday, March 5 1:00 to 3:00 pm

Addressing the confusion around face coverings, masks, and respirators. Join our interdisciplinary team who will provide guidance on some of the many questions being asked by workplace parties and the public. 

During the pandemic, information about face coverings has become confusing and a point of contention. Most people want to find the best way to protect themselves and others.  There is a lot of  confusion between “masks”, “respirators” and various other types of face coverings.

Moderator:

Dr. Simon Smith, recently retired from career in respiratory protection research but continuing dedication to ISO, CSA and AIHA Respiratory Protection Committees and Working Groups. Slides

Speakers:

Lisa Brosseau, Industrial Hygienist, Speaker, Award-winning professor, researcher, writer, educator. Slides

Amanda Jones, Senior Scientific Evaluator, Health Canada.

Maria Negulescu, P.Eng.  Industrial Technology Advisor, National Research Council Canada.

Slides

Stacy Richardson,  Senior Health & Safety Application Professional, 3M. Slides

In this session, an interdisciplinary team will provide guidance on some of the many questions that are being asked by workplace parties and the public:

  • Face Coverings, masks and respirators- how are they different?
  • What works as “source control”, to protect others from us?
  • What is needed to protect us from virus coming from others?
  • How do you know if your face covering really works?  Can you combine?
  • What standards (if any) apply to face coverings, masks (surgical), and respirators? How does a manufacturer get a product certified as meeting a standard?
  • What types face coverings, masks (surgical), and respirators are tested?  What has the testing shown us?
  • Are N95s (or more protective) respirators,  being manufactured in Canada?  Are there any barriers?
  • How do you know if your respirator might be a counterfeit?  
  • How do you assure a good face fit?
  • Do we still need to preserve stocks of N95 (or more protective) respirators for health care and other frontline workers?  
  • What do we know about re-using and cleaning respirators?

Occ-COVID- A Medical Perspective: What We Know about the Long Term Health Effects. 

Friday, January 15th, 2021 from 1:30 to 3:00pm

Update: Video now available here, slides linked below.

With more than 73 million documented infections of COVID-19 and 1.6 million deaths worldwide, the coronavirus disease 2019 (COVID-19) pandemic continues unabated. The clinical spectrum of SARS-CoV-2 infection ranges from an asymptomatic infection to a life-threatening and fatal disease. Current estimates are that approximately 41 million people globally have “recovered”; however, clinicians are observing patients with persistent symptoms and others who develop complications after SARS-CoV-2 infection. Because COVID-19 is a new disease, much about it remains uncertain—in particular, the possible long-term health consequences. 

Join us on January 15 as Dr. Pravesh Jugnundan, Occupational Medicine Physician provides a medical overview of COVID-19 and describes the long-term effects on physical and mental health as we know them today. 

Slides available here.

Followed by Dave Wilken who will discuss the importance of recognizing COVID-19 as an Occupational Disease, including advice on determining work-relatedness, the value of establishing a WSIB claim and how OHCOW can assist.  

Slides available here.

It is time for effective PPE as a Control: Respiratory Protection During COVID Winter

Friday, December 11th, 2020 from 1:30 to 3:00pm

Update: Video now available here, slides linked below.

The current surge in Covid case numbers in Canada is likely to climb throughout winter, particularly given increased time spent - and interactions - indoors, compounded by the difficulty in maintaining natural ventilation at low temperatures. Therefore, every workplace needs to consider and boost alternate controls, including the proper use of effective respiratory protection. This will be critical to protect all frontline workers, in and out of healthcare. Scientific studies have shown properly fitted (and worn) N95 (or better) respirators provide greater protection than surgical masks. Understand the difference, see the impact of making the wrong choice, and learn how judicious use is making a difference in Covid prevention around the world.

  1. International lessons from China and Australia, Kevin Hedges, OHCOW 
  2. Canadian lessons from SARS 1 and now 2, Alec Farquhar (Mario Possamai)
    View slides from Mario Possamai's presentation here.
  3. Elastomeric respirator effectiveness and use, Nicolas Smit  
  4. Respirator Program Considerations for Non-Healthcare Workplaces – Evaluating the Need and Implementation Guidance for COVID-19.  Kevin Hedges (obo Dr. Margaret Sietsema, University of Illinois)

Transmission Reduction, Ventilation Optimization & Knowledge Activation for effective Workplace Prevention

Friday, November 27, 2020 from 1:30 to 3:00pm

UPDATE: Videos now available here, slides below.

OHCOW’s Occ-COVID series will continue on November 27th with more Science & Solutions including our in-house experts and guests sharing: Latest transmission evidence; Ventilation/Control implications; and other practical approaches to workplace prevention.

In less than a year, COVID-19 has become one of the most significant occupational diseases of our time, with thousands of workers exposed, hundreds seriously ill and an unacceptable number killed in Ontario alone.  

With winter arriving and cases surging in the Province, more needs to be done to control this deadly virus.  Much can be learned and applied from recent transmission, infection risk and exposure control science, but it is also valuable to review critical basic tenets of hazard communication and participatory health and safety to find solutions that work in real life situations.

Get the best COVID-19 prevention advice you can find here, plus the opportunity to dialogue with other interested (and committed) workers, supervisors, managers and owners from the workplaces of Ontario, along with Worker Advocates, Joint Health and Safety Committee members, Health and Safety Professionals; Researchers & Prevention System partners and stakeholders.
