"Wonder if folks are reluctant to share any such specific documents on here because of concern for being taken on by others about using or giving out generic/non-specific documentation?" Nope that's not the problem, this has been asked 100 times before with essentially the same answer....The best and most accurate checklist is the standard itself ... Up to a point! Once each "shall" has been asked and answered in the affirmative it's time to move on.
So if you've got a copy of each standard you already have a checklist....And get rid of 18001, it's history and replaced by ISO 45001. An integrated checklist is no more that combining the common elements and adding the specific element form each document. If you take the time to check the "Attachment List" on the top bar you'll find everything that has been shared there. However if that's too hard try this as a start, it took less than 5 minutes with a quick internet search.
