@ -103,12 +103,16 @@ There are three predefined activities in the tool at present.
**Call Centre** = All persons seated, all talking simultaneously, all the time. This is a conservative profile (i.e. will show in increased ``P(i)`` compared to office/meeting) if used for office activity.
**Workshop** = Based on a mechanical assembly workshop, all persons are standing and talking 50% of the time. Everyone (occupants and infected occupants) is treated the same in this model.
**Lab** = Based on a typical lab or technical working area, all persons are doing light activity and talking 50% of the time. Everyone (occupants and infected occupants) is treated the same in this model.
**Workshop** = Based on a mechanical assembly workshop or equipment installation scenario, all persons are doing moderate activity and talking 50% of the time. Everyone (occupants and infected occupants) is treated the same in this model. This model is equally applicable to bicycling, or walking on a gradient, in the LHC tunnels.
**Training** = Based on a typical training course scenario.
One individual (the trainer) is doing light exercise (standing) and talking, with all other individuals seated and talking quietly (whispering).
In this case it is assumed that the infected person is the trainer, because this is the worst case in terms of viral sheeding.

**Gym** = Included for comparison purposes only, all persons are doing heavy exercise and breathing (no talking). Everyone (occupants and infected occupants) is treated the same in this model.
