Steps
Identify which Z359 part applies to the specific component: general fall-arrest system components typically reference Z359.1, assisted/self-rescue equipment references Z359.4, and descent controllers reference Z359.9
Check ANSI/ASSP's own current listing for the presently published edition of the relevant part rather than assuming the edition cited in older manufacturer literature is still current
Confirm the manufacturer's equipment documentation states conformance to the specific part and edition being relied upon
Confirm that a nationally referenced US standard, not a CE/EN marking alone, is the basis for US job compliance; if equipment is only CE/EN-marked, verify separately whether it also meets the applicable ANSI/ASSP part before using it domestically
Retain manufacturer conformance documentation with the equipment's inspection records
Known gotchas
Multiple Z359 parts get revised on different schedules - confirm the edition year for the specific part in question rather than citing one part's edition year for another
CE/EN marking on imported equipment does not by itself establish compliance with the applicable ANSI/ASSP Z359 part for US work; treat the two systems as separate unless the manufacturer documents both
