Respiratory protection exemptions: Respirators are not required for common non-pathogenic RG1 organisms like OC43 (the common cold). Respirators are not required when RG2 and RG3 risk is low as determined by risk analysis by a Qualified Person.

Respirators are not required in Exempt Zones that have been engineered or otherwise determined to provide low risk of exposure, equivalent to wearing a respirator in a contaminated space, by a Qualified Person.

Access: A variety of respirator models and sizes are to be provided. Respirators are to be provided at all entrances, nurses stations and outside of patient rooms. Patients and visitors are encouraged, but not mandated, to also wear respirators.

Impact: In Canada, approximately 1/3 of respiratory infections in healthcare are due to transmission in the healthcare facility.

While CSA Z94.4 is an Occupational Health & Safety (OHS) Standard intended to protect workers, universal respirator use will also protect patients, visitors and local communities.

Leadership: This will be the world’s first National Standard to require precautionary, universal respirator use in healthcare. It may inspire other countries to follow suit.

Cost: Hospitals, provincial governments & federal government warehouses are overstocked with hundreds of millions of respirators due to expire shortly. They are already bought and paid for. The cost to recycle or send them to landfill outweighs the cost of using them.

Opposition: The usual anti-mask / anti-airborne leaders in IPAC and Infectious Disease who have long waged a campaign against precautionary use of N95s have taken aim to oppose the new CSA National Standard starting with a petition opposing CSA Z94.4.

Support: It’s important that supporters weigh in on CSA’s precautionary approach to respiratory protection both publicly and through the official CSA Public Review process.

Share this information widely. Show your public support for CSA Z94.4 and the precautionary, universal use of respirators in healthcare through media, social media and word of mouth.
