Different protocols offer different levels of protection. Wherever possible, use the protocol that offers the highest level of protection. Consider controls from additional levels if the first level isn’t practicable or does not completely control the risk.
- First level protection (elimination) — Limit the number of people in your workplace where possible by implementing work-from-home arrangements, establishing occupancy limits, rescheduling work tasks, or other means. Rearrange work spaces to ensure that workers are at least 2 m (6 ft.) from co-workers, customers, and members of the public.
- Second level protection (engineering controls) — If you can’t always maintain physical distancing, install barriers such as plexiglass to separate people.
- Third level protection (administrative controls) — Establish rules and guidelines, such as posted occupancy limits for shared spaces, designated delivery areas, cleaning practices, and one-way doors and walkways to keep people physically separated.
- Fourth level protection (PPE) — If the first three levels of protection aren’t enough to control the risk, consider the use of masks. Ensure masks are selected and cared for appropriately and that workers are using masks correctly.
