Table 1 Classification of SF areas based on crowding

A

Walk-through areas

Areas where people will pass through without stopping

Hallway, lobby, parking lot

Consider creating one-way routes

B

Short stay areas

Areas where people can only stop briefly, 15 min at the most

Hall, toilet room

Consider placing physical distancing footprint floor signs in waiting areas

C

Prolonged stay areas where adequate physical distancing can be maintained

Areas where people are expected to stay for longer than 15 min, even several hours

Offices, classrooms, debriefing rooms, control rooms

It is mandatory to wear surgical face masks and to observe physical distancing. Shoe covers might be considered. These areas should also be adequately ventilated.

D

Prolonged stay areas where adequate physical distancing cannot be maintained

Areas where people are expected to stay for longer than 15 min, even several hours

Advanced simulation rooms, laboratories with task trainers

It is essential to wear other protective devices (e.g. gloves, goggles or visors, waterproof gowns) besides surgical face masks. All environmental surfaces should be cleaned and sanitized at the end of each simulation scenario. Rooms should also be adequately ventilated

E

Gathering areas

Indoor or outdoor areas where large groups of people are expected to gather in limited spaces

Main entrance, reception desk, toilet room entrance elevator, stamping area

It is essential to avoid gatherings whenever possible. Potential strategies include staggered entries, staff shift review, etc.
