Royal Australian Navy learned about this risk the hard way with a fatal fall during hoist ops with an S-70B-2 on 20 Dec 1995. For details, see for example:

I have a memory of reading about a much more recent Australian case of dynamic rollout reported by the ATSB which I thought also related to hoist operation, but not sure how to search for it now. The only ATSB report I could find easily was for a sling load case:
