Recommendations
The program recommends testing at the beginning of each production
using the exact conditions (equipment, amount of fog used, length
of fog cue, performers’ and crew members’ positions
relative to the fog equipment, air circulation, room temperature,
etc.) that will be used during performances. Theatres should
then monitor fog use to ensure that performance conditions replicate
testing conditions. If conditions are consistent, there should
not be a need to repeat the test during the production run. Thus,
testing can be a one-time cost when a new production loads in,
not an additional cost for each performance.
Please note that e-cigarettes are outside the scope of the Fog Testing Program.
