Are Ontario Workers Required to Follow CSA Standards of Fit Tests?
Respiratory protection requirements by Province states Ontario OHS regulation doesn’t include specific fit tests requirements for respiratory protection. Yet, CSA Z 94/4-02 does. Therefore, under Ontario regulations, are workers not required to follow CSA standards to be fit tested prior to using SCBA and other respirators?
Ontario’s OHS regulations don’t spell out fit test requirements nor do they specifically adopt CSA Z94/4-02, which does address fit testing. However, although technically fit testing may not be specifically required, doing fit tests is likely to be considered a best practice and one of the reasonable steps employers in Ontario should take to protect workers from airborne hazards under the general duty clause.
