This came up with a surveyor when we were opening BAMC in 92! It was assumed by many, me included that you were issuing a CRS, when he said although the wording was the same there was no legal requirement to issue/sign a CRS on every task/work card.
I signed 1 or 2 at the end, now that is scary when you rely on so many others getting it right, mainly the fact that the planners have actually issued the correct work pack etc, a few times things were added at the last minute!
