What are considered ‘safe’ staffing levels for reducing transmission risk in indoor spaces?
Although there are no “safe” levels for occupancy of a room, you can judge the appropriate number of people for a space can be made based on the type and size of space, the activity, the duration of time spent there, and the ventilation.
The following rules of thumb can help:
- Prioritise keeping occupancy lower in the spaces where people spend the most time together
- Minimise exposure at very close range. Spacing out desks or workstations to be at least 1m apart is a good idea.
- Ensure that there is sufficient fresh air ventilation for the occupants (see ‘Ventilation’ in these FAQs for more advice.)
- Enable lower occupancy and higher rates of ventilation in spaces where people may be very vulnerable to infection, or where there are activities such as singing or aerobic exercise which generate more respiratory particles.
