Working During a Pandemic

As the risk for infection gets higher, for higher risk jobs, such as health care workers (HCW) working in close proximity to COVID19 patients; it is even more important that more emphasis be placed on increased ventilation.

The OHCOW Workplace COVID-19 Risk Management (Control Banding) Matrix infographic has adapted the OSHA Risk Levels into a control banding matrix to help support decisions on risk management.

Snapshot of a Risk Management infographic

This infographic is provided as a “communication and education tool”, to highlight that “higher order controls” are in fact much more effective than personal protective equipment and that the degree of infection protection control (IPC) should be commensurate with the level of risk.
It can be used along with OHCOW Regional Risk Tool and Tips which provides “additional practical advice” which in addition incorporates “community transmission” which should be considered in the occupational health risk assessment.

The US Department of Labor, Occupational Safety and Health Administration (OSHA) has simplified the risk management process by assigning risk levels to different jobs and assigning controls based on the risk level which is described in more detail in:

Guidance on Preparing Workplaces for an Influenza Pandemic

(OSHA, 2009)


Guidance on Hazard Recognition and Classifying Risk of Worker Exposure to SARS-COV-2

(OSHA, 2020)


Guidance on Control and Prevention

(OSHA, 2020)


Guidance on Returning to Work

(OSHA, 2020)


The guidance provided by OSHA, for each risk level, has been aligned in the infographic with the hierarchy of controls (HOCs) to reinforce that higher order control (such as ventilation) are even more important when managing the risk of infection from an aerosol transmissible disease (SARS-COV-2).

OHCOW has been working with various labour and academic partners using surveys to capture pandemic workers’ experience (in healthcare, essential workers, working from home, and educators).  We have also been involved in demonstrating the science behind aerosol transmission of the SARS-CoV-2 virus and the measures need to protect workers and workplaces.  We have also invited various experts and researchers to share their knowledge regarding the pandemic during numerous online and archived webinars.

Working Together to Communicate Important COVID-19 Prevention Information to the Ontario Agricultural Sector

COVID19 introduces serious and complex health and safety challenges for the arrival, isolation and work of temporary foreign workers in Ontario agriculture, particularly in regard to healthcare capacity, public and occupational health, and workplace communication and coordination for this disconnected population, made more vulnerable by high-density housing.

OHCOW Migrant Farm Worker Program (MFWP) staff continue to collaborate with employers, workers, partners and stakeholders and offer experience and support to contribute to frontline planning, preparedness and response.

Pandemic Experience Surveys

OHCOW has conducted two surveys over the course of the current COVID-19 pandemic.

Round two of the general workers survey is ongoing.
Share your pandemic work experience, by taking part in the survey using the survey buttons below:

Survey of HEALTHCARE WORKERS’ Experiences During the COVID-19 Pandemic

OHCOW workplace stress experts, along with several academic and labour partners, have developed a survey to measure The Experiences of a Healthcare Worker During a Pandemic. It is based on a number of scientifically-recognized questions that measure different aspects of job-related psychosocial conditions, along with symptoms related to intense stressful conditions and mood disorders.

Survey of WORKERS’ Experiences
During the COVID-19 Pandemic

Building on the success of the Healthcare Worker Pandemic Experience Survey*, OHCOW and its partners have now created and launched a more “generic” Survey of Workers’ Experiences During a Pandemic to recognize the impact that working during the COVID-19 pandemic is having on all workers in the province (country and world).

*which already has more than 3500 respondents
