If the result of the above calculation exceeds the maximum
concentration level then make similar calculations for the second
then third smallest room and so until the result falls short of the
maximum concentration.

Dealing with the situations where the result exceeds the
maximum concentration level.
Where the installation of a facility results in a concentration in
excess of the maximum concentration level then it will be
necessary to revise the system.
Please consult your supplier.
