requirementisfullled:
Stackedsystemsmaynotfalleveniftheyareinclinedmorethan10°inanydirection.Tofullthis
requirementtakemeasurestoachievecompliance.Onepossibilityisstrappingthestackedspeakers
toasolidbaseorusingsafetystraps.
6.1.3 Accurate alignment of the speakers

beused.
Whenchainhoistsareinoperationensurenobodyisdirectlyunderneathorinthevicinitytotheload.
6.2.1 Visual inspection
Toreduceriskofaccidentsbyfailureordysfunctionofacomponentallsystemsneedregularchecks.
