Page 30/82 PS S ERIES HARDWARE SETUP PROCEDURE
• The PS Series Rigging System requires regular inspection and testing by a competent test
centre. NEXO recommend that the system is load tested and certified annually or more
frequently if local regulations require.
• When de-rigging the system ensure that the same duty of care is given to the procedure as for
the installation. Pack PS Series components carefully to prevent damage in transit.
7.1.1 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.
