3:00 I would also want to check for splinters embedded in the rope from prior climbs. This happens in the entertainment industry often but usually only on the working line & not a belay or rope access line.
Possible 10 year life span but if you are using it often maybe 5 year life and if you're a production climber you could retire it in a year. Here is an article on it. Hope this helps. tcimag.tcia.org/training/head-protection-selection-care-and-retiring-helmets/
