Meyer Sound LEO Series Assembly Manual page 10

CHAPTER 1: INTRODUCTION
Regulatory Compliance
The design and safe working load (SWL) ratings of the QuickFly system are intended to be in compliance with all known reg-
ulatory statutes currently applicable in the United States. Unless otherwise specified, all working loads are based on a 5:1
safety factor. However, as noted above, there are wide variations internationally in the regulations and practices applying to
suspension of sound systems in public places. Although regulations in the United States are generally among the most
stringent, safety codes may be even stricter in a few localities (such as those highly prone to earthquakes). In addition,
applicable safety codes are open to interpretation: government officials in one location may have a stricter interpretation
than another local official, even when operating under the same regulations and in the same legal jurisdiction.
Consequently, users of QuickFly rigging systems should be prepared to take additional safety assurance measures beyond
those outlined in this Statement. IN ALL CASES, IT IS THE RESPONSIBILITY OF THE USER TO MAKE CERTAIN THAT ANY
MEYER SOUND LOUDSPEAKER SYSTEM IS SUSPENDED IN ACCORDANCE WITH ALL APPLICABLE NATIONAL/FED-
ERAL, STATE/PROVINCIAL, AND LOCAL REGULATIONS.
Safety Responsibilities "Above the Hook"
In most touring applications of rigging systems, the touring sound provider is normally responsible for ensuring the safety of
the suspension system only below the attachment point. The safety and suitability of the attachment point is generally seen
as the responsibility of the venue owner or operator. However, this distinction ("above the hook" versus "below the hook")
can be open to interpretation. Touring system operators should double-check to make certain that attachment points are
approved and suitably load rated, and that the points used are those identified as such by the venue owner or operator. As
an extra precaution, careful inspection of the attachment points is advised before flying, particularly in older venues or those
hosting frequent events using large sound and lighting systems. IN ANY CASE, MEYER SOUND QUICKFLY SYSTEMS ARE
INTENDED ONLY FOR SUSPENSION FROM APPROVED RIGGING POINTS, EACH KNOWN TO HAVE AMPLE SWL MAR-
GINS FOR THE SYSTEM COMPONENTS SUSPENDED BELOW THEM.
Inspection and Maintenance
The Meyer Sound QuickFly systems are an assembly of mechanical devices, and are therefore subject to wear and tear over
prolonged use, as well as damage from corrosive agents, extreme impact, or inappropriate use.
BECAUSE OF THE SAFETY ISSUES INVOLVED, USERS MUST ADOPT AND ADHERE TO A SCHEDULE OF REGULAR
INSPECTION AND MAINTENANCE. IN TOURING APPLICATIONS, KEY COMPONENTS MUST BE INSPECTED BEFORE
EACH USE. Such inspection includes examination of all load-bearing components for any sign of undue wear, twisting,
buckling, cracking, rusting, or other corrosion. In regard to rust and corrosion, the main components of a QuickFly system
are either protected by an exterior coating or made from stainless steel, which is impervious to rust and resistant to most
corrosive fluids. Nevertheless, normal use and shipping vibrations can wear through the protective coatings, and extremely
corrosive fluids (such as battery acid) can cause severe damage with prolonged exposure even to protected parts. Particu-
lar attention should be given to screws, bolts, and other fasteners to make certain the fittings are tight and secure. Metal
seams and welds should be examined for any sign of separation or deformation. Meyer Sound strongly recommends that
written documentation be maintained on each QuickFly system, noting date of inspection, name of inspector, points of sys-
tem checked, and any anomalies discovered.
Annual Comprehensive Examination and Test Program
In addition to routine checks on the road for touring systems, Meyer Sound also recommends a careful, comprehensive sys-
tem examination and testing "at home" in the warehouse or other appropriate location at regular intervals. Such at home
examinations and tests should occur at least once a year, and should include a careful inspection of each component under
ideal lighting conditions, and then a final comprehensive check of the entire system after it has been flown.
If any anomalies or defects are discovered that could possibly affect the safety or integrity of the system, affected parts or
subsystems should be replaced in their entirety before that part of the system is flown again.
