4 SAFETY POINTS & PROCEDURES
(1). To ensure safety, the rigging of loudspeaker flying systems in public or
working areas should only be undertaken by specialists, contractors, venue
or touring crew personnel with established, proven expertise as riggers and
who have read this manual.
Personnel assembling a system on site have a duty to ensure the safe
construction, adjustment and deployment of the system. Before use all the
system components must be subjected to careful and rigorous inspection
and any component or assembly which has been misused or damaged
must be immediately rejected and replaced. If there is any doubt
whatsoever about the safety and integrity of the system, then it must not be
deployed.
(2). The safety of the system is affected by its operating environment. If for
instance, a flying system is deployed out-of-doors during heavy rain, high
winds or storms then inevitably, safety will be compromised.
(3). All adjustments to the system must always be carried out only by hand
- no levers, hammers, mechanical implements or other aids should be used
to apply additional force.
(4). All mechanical systems, flying systems included, eventually wear out.
The way the system is used, lack of maintenance, exposure to water or
corrosive agents, deformation or damage through improper storage or
transport will all accelerate the process of deterioration and reduce the
safety of the system. Owners and users of the flying system must take all
practical steps to protect the system from deterioration.
(5). The most important rule to follow when constructing and deploying the
system is to check, check and check again. Never assume or take anything
for granted - the most experienced and competent system riggers can (and
sometimes do) make mistakes so always check your own work and that of
the person next to you.
(6). It helps in the case of larger arrays to have a work platform of
sufficient height available in order to avoid having someone clamber over
the swaying array to carry out adjustments. Please note that it is not
possible to adjust/or remove quick release pins with the array suspended in
the air - the array must be lowered to the ground.
(7) Before flying the system, particularly with large arrays, it can save time
and frustration later on to have a crew member temporarily wire up the
controller racks and provide a test signal to check the speaker wiring -
when the check is complete, be sure to disconnect the loudspeakers at the
racks before raising the system.
