The County Council monitors capacity in our rooms by measuring Co2 in the air because it gives us a good indication of air quality.

 

If the Co2 level approaches an unacceptably high reading then we are required to take evasive measures to reduce it.  This may be as simple as opening a window but equally it may be necessary to evacuate the room until the level has dropped sufficiently.

 

If a meeting were being held in a room then a recess to enable the reading to drop would not be a serious concern but it would be extremely disruptive for all participants in a ceremony.  For this reason we are required to exercise more caution when considering the number of guests in a ceremony than might be permitted for a meeting.
