Walls, floors and ceilings must be capable of supporting the actual load placed upon them.
The rigging hardware must be safely and securely fixed to both the loudspeaker system
and the supporting structure.
When mounting components on walls, floors or ceilings ensure that all fixings and
fasteners used are of an appropriate size and load rating. Wall and ceiling claddings, and
the construction/composition of walls and ceilings also need to be taken into consideration
when determining if a given suspension method is safe.
5.1.1 - Secondary Safeties
It is best practice to ensure that all loudspeakers flown in any given environment should
be provided with a second, independent and properly rated safety suspension point in
addition to the principle load bearing means of suspension. Steel wire ropes or steel
chains of an approved construction and load rating only may be used as secondary
safeties. Plastic covered steel chains may not be used as secondary safeties under any
circumstances. Also ensure that all local and national laws are complied with when
determining your primary and secondary suspension points.
5.1.2 - Safety Inspections
Carefully inspect all flying system components prior to use for defects or signs of damage
prior to flying your MSE-159SP. If any components damaged or you suspect them to
be damaged, DO NOT USE THEM.
Regular scheduled tests – which are much more rigorous than visual inspections – of all
rigging components must also be carried out. Safety legislation, and test/inspection
requirements, will vary from country to country and as such it is the user’s responsibility to
ensure that local regulations are adhered to. In most cases, annual independent tests &
inspections carried out by a suitably approved and qualified inspector will be required.
EM Acoustics recommends detailed logbooks be kept of all inspections and load tests to
ensure an accurate record is kept of the testing for each EM Acoustics rigging accessory.
When flying any loudspeaker system, always wear protective headwear, footwear and eye
protection in accordance with local regulations.
The rigging of a flown loudspeaker system may be dangerous if not undertaken
by a suitably experienced and qualified rigger. Installation & fixing of all
hanging points should only be carried out by a professional rigger in
accordance with local legislation as well as the rules of the venue. The house
rigger and/or venue manager must always be consulted.
