4.0 - Safety Considerations
General Considerations in use
Loudspeaker systems are potentially dangerous objects if used incorrectly. Please ensure
that you read this section fully, and contact EM Acoustics or your local dealer should you
be in any doubt over correct operation procedures.
Personal Injury
Never stand in the immediate vicinity of loudspeakers when in use at high level.
Professional loudspeaker systems are capable of producing sound pressure levels which
can cause permanent damage to human hearing. Levels in excess of 90dB can cause
hearing damage if people are exposed to them over a long period of time, so care and
attention must be used for both staff and audience members.
When deploying loudspeaker systems on the ground or when flown, please take careful
note of the following important safety considerations:
•
Only use accessories and flying hardware supplied or approved by EM Acoustics for
flying or transporting loudspeaker systems. Pay close attention to specific
instructions, especially those considering maximum load capabilities as detailed in
the appropriate user manuals or on the legend labels on the accessories
themselves.
•
Ensure all additional accessories, fasteners and secondary safeties are of an
appropriate size, working load limit and safety factor.
•
All loudspeakers and accessories should be regularly inspected for signs of wear
and tear, and any damaged parts should be replaced.
•
All load bearing parts and assembly bolts on accessories should be regularly
checked to ensure they are tight and not worn.
Ground Stacking
•
Ensure that the floor or stage surface can withstand the weight of the system.
•
Wherever possible, avoid high stacks and use ratchet straps to secure loudspeakers
together. Please also remember that vibrations from subwoofer systems can shake
other loudspeakers out of place, which may present a toppling hazard. The use of
ratchet straps and non-slip material is recommended to prevent this.
