ASME B30.9-2006 MAY GIVE THE IMPRESSION THAT RECORD KEEPING AT THE PERIODIC LEVEL OF INSPECTION WOULD BE DONE ON THE BASIS OF “LOT” INSPECTION(S)?
“Lot or batch” inspections would be an acceptable way to record the occurrence of the inspection. The fact a sling is still in the tool crib and was not destroyed indicates it passed the last inspection. An unscrupulous inspector could indicate all of their slings were inspected and passed without ever having done an inspection. The same unscrupulous inspector could just as easily put unique marks on each of their slings and record that said slings were inspected, passed and left in service. The inspector dates and signs the inspection “record”, noting the various locations and the facility keeps the signed copy. The requirement is met for record keeping. It would probably help in the credibility of the inspection and recordkeeping process if the record reflected if any slings were destroyed or removed from service.
