(8). During the set-up operation and especially during all lifting operations
the safety of the work crew should be paramount. Site safety rules must be
clearly understood and observed by all.
One competent, experienced person should be in charge of operating the
hoists and should issue a clear loud warningand be satisfied that everyone
is clear of the load before operating the hoists. For their safety, all site
personnel not engaged in setting up the array should be kept clear of the
working area. As the chain hoists operate, there is absolutely no need for
anyone to be in the area directly beneath the array or in the near vicinity of
that space.

CARE & MAINTENANCE
All mechanical systems with moving parts are subject to wear and tear and
the W8L flying system is no exception to this rule. Damage to the system
components from long term wear and tear, accident, or the application of
excessive force during set-up or adjustment can all increase the risk of
mishaps.
The W8L flying system is a safety-critical mechanical assembly so is vitally
important that users adhere to a strictly enforced and documented regime
of inspection and preventative maintenance. All those who set-up and use
the system must be fully informed of safety inspection procedures and their
responsibility for their implementation. The following information and advice
is intended to promote the safety and well-being of everyone: equipment
owners, users, performers and of course, the public.
The principal flying system components are all finished in a black powder
coat finish. Under normal conditions of use, this finish will, unless damaged,
protect the main components against rusting and corrosion. However, it
should be clearly noted that any exposure to water, rain, or corrosive
chemicals during transport or use could weaken elements of the system. At
greatest risk from rust and corrosion are the moving parts used to connect
or join the enclosures. Frequent, thorough inspection for evidence of
corrosion is absolutely essential - as is the application of a moisture
displacing treatment such as WD40 on exposed bare metal parts.
As a general rule, the system should be subjected to close visual inspection
every time it is unpacked or packed. To provide a cross-check, the
inspection should be carried out by more than one person. For record
purposes and as an aid to consistency, a log book with a printed check list
of inspection steps should be packed with the system so that users can
check off each element of the inspection procedure as they carry it out.
The log book should also register the details of the system such as a full
parts inventory, the serial or unique numbers stamped or engraved on the
parts, a comment section for users, details of where and when the system
has been used for shows with references to the venue rigging plan and
system details.
