6.1.2 Ground stacking safety
Statistically, many more injuries occur due to unstable ground stacked PA systems than those associated with flown systems.
There are several reasons for this fact, however the message is clear:
Always survey the supporting structure upon which a ground stack is to be built. Always look beneath PA wings to inspect the
deck support and if necessary ask for the stage scrims and dressings be removed to allow access.
If the stage surface slopes, as it does in some theatres, ensure that the system is prevented from sliding forwards due to
vibration. This may require the fitting of timber battens to the stage floor.
For outdoor systems ensure that that the system is protected from wind forces which might cause the ground stack to become
unstable. Wind forces can be huge, especially upon large systems, and should never be underestimated. Observe
meteorological forecasts, calculate the “worst case” effect upon the system prior to erection and ensure that the system is
secured appropriately.
Take care when stacking cabinets. Always employ safe lifting procedures and never attempt to build stacks without sufficient
personnel and equipment.
Never allow anyone, whether operators, artists or members of the public to climb onto a ground stacked PA system. Anyone
who needs to climb over 2m (6 ft) high should be fitted with suitable safely equipment including a clip-on harness. Please refer
to local Health and Safety legislation in your territory. Your dealer can help with advice on access to this information.
Apply the same attention to all safety matters when de-stacking systems.
Be aware that safety procedures are as important in the truck and in the warehouse as they are at the venue.
