In general all the recommendations for the safety distances given in here are basing on the condition
that there is no wind at all! Windy conditions will lead to the result that the effects are drifting sideways
accordingly, especially if gas bottles are being used. This must be considered when choosing the
position for the installation, choosing a nozzle size and the operation pressure. Due to the fact that the
usage of the devices is beyond our control expressly disclaim any liability for any damages resulting
from insufficient safety distances. Therefore we are only giving recommendations regarding the safety
distances instead of fixed values. Every user must decide by himself which minimum safety distance is
required for his application.
Utmost care must be taken if actors are wearing costumes that are easily inflammable. In such cases
the safety distance must be increased dramatically. If in doubt the effect has to be omitted.
