If a worker cannot be fitted to a respirator, what is the recommended action?

In situations where a worker cannot be fitted with a respirator, the most appropriate action is to provide reasonable accommodations to ensure their safety and health. Allowing the worker to take breaks every 10 minutes offers them the opportunity to rest and potentially reduce their exposure to hazardous environments where respirators would be necessary. This approach prioritizes their well-being while also enabling them to continue working in a controlled manner.

Alternative equipment is sometimes a feasible solution, but it may not always be available or appropriate for the specific hazards present. Allowing the worker to leave the site immediately would disrupt workflow and does not necessarily address the risk of exposure in the interim period before their departure. Terminating the worker's contract is a serious action that may not be justified simply because a respirator fitting is not possible, especially when other accommodations could be made to ensure safety.
