What are the potentially riskiest points for transmission of COVID-19 in a manufacturing plant?

Risk areas will vary from one plant to another based on layout and staffing levels. In general, common areas to consider in establishing cleaning, physical distancing, maximum occupancy, and entry/exit protocols include washrooms, change rooms, lunchrooms, and stairways, as well as door handles and other frequently touched surfaces. Beyond that, any space where 2-metre physical distancing is not possible is a risk point that requires effective controls.
