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

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

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.

  • Addressing Airborne Transmission by Doing Something about Ventilation, John Oudyk, OHCOW
  • Writing the Workers Back In:  Sparking Knowledge Activism to fight COVID-19, OFL Section 21 Health Care Committee members
  • Sharing Workplace Success Strategies Panel Discussion/Q & A , All

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.

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

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

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)

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)

5) Panel Discussion and Q & A

Part 1: Science & Solutions

Session 1: Covid-19 Transmission: Taking Stock of the Science 

UPDATE: Video now available here.

Date: July 7th

Time: 12:30-2:00 PM

Moderated by Dr. Raymond Tellier- https://www.mcgill.ca/newsroom/raymond-tellier


Session 2: Solutions: The Hierarchy of Prevention/Control Banding

The Role of Infectious Dose and the Hierarchy of Prevention (Controls) for COVID-19

UPDATE: Video now available here.

July 8th 12:30 -2pm

Moderated by Dr. Kevin Hedges, OHCOW Hygienist.

The role of infectious dose and the hierarchy of prevention (controls) for COVID-19

International experts in infection control, occupational hygiene, and respiratory protection will discuss up to science, controls and methodology related to exposure to coronavirus and prevention of COVID-19. This session will build on the science delivered in session 1, and provide advice on the importance of the hierarchy of controls (HOC) which includes ventilation as a higher order control along with appropriate and effective personal protective equipment (PPE).

  1. Dr. Lisa Brosseau, ScD, CIH – The Role of Infectious Dose in Identifying and Managing COVID-19 Risks (15 mins).
  2. Deborah Gold MPH, CIH - Experience with Cal/OSHA's Aerosol Transmissible Disease Standard (15 mins).
  3. Prof. John Cherrie - Ventilated headboards and the need for novel controls for SARS-CoV-2 (15 mins).
  4. Dr. Simon Smith – Selecting effective respiratory protective equipment (RPE) for SARS-CoV-2 (15 mins).
  5. Q&A (30 mins).
