Updates to protective equipment guidelines

Tuesday, January 4, 2022

This message was originally sent to employees by Kate Windsor, Director, Safety Office.


To increase the protective factor of face coverings against the highly transmissible omicron variant, we are reminding all employees and students to wear a mask that meets the Public Health Agency of Canada’s (PHAC) recommendations in general, non-health care areas. Supervisors should ensure that employees are provided with appropriate face coverings in respect of their work environment.  

Non-medical masks can help prevent the spread of COVID-19 similar to medical masks if they: 

  • fit well 
  • have multiple layers, including at least 2 layers of breathable tightly woven fabric, such as cotton and an effective middle filter layer 

Medical masks that are certified ASTM Level II provide good protection when worn properly. Medical masks are typically single use and disposable, but may be reused until visibly dirty, damp or damaged. 

As per PHAC’s advice, ways to improve fit include: 

  • adjusting bands or ear loops and the flexible nosepiece 
  • tying knots in the ear loops and tucking the sides of the mask so that it lies flat 
  • layering a well-fitting non-medical cloth mask over a disposable mask  
  • keeping facial hair shaved or short, if possible 

Masks are worn properly only if they cover the mouth, nose and chin and fit snugly.  

Two appropriate options for face coverings are available centrally at no cost to units for employees performing essential in-person work (including teaching), via Central Stores catalogue. Please order only what is needed for essential in-person activities – limits may apply.  

  • Reusable, washable 3-layer cotton and polyester cloth face mask with filter pocket and adjustable ear loops. Order with 5-layer disposable filters; and 
  • Disposable medical grade ASTM Level II masks. 

As a reminder, where an employee is providing services to a person in any circumstance who is not wearing a mask or face covering and is not separated by plexiglass or some other impermeable barrier, the employee is required to wear appropriate PPE i.e., a medical grade mask as well as eye protection.  

  • Eye protection can include appropriate safety glasses/goggles or a face shield (available via  Central Stores) and must: 
    • Fit properly and not interfere with the proper fit of a mask 
    • Provide a barrier to splashes from the side  
    • Not create an additional hazard in relation to the type of work being performed  

Please refer to the COVID-19  Health & Safety Guide  for protective equipment requirements. Supervisors should update safety plans as is necessary.
