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.
Safety Inspections
Carefully inspect all flying system components prior to use for defects or signs of damage prior to
assembling a HALO Compact array. 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 AMT drive unit has a very powerful magnetic field and as such, care should be taken to avoid
items becoming magnetized to the outside of the enclosure.
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.
