I was in charge of idiots on a line job, (except Jeff), i was so worried, i put plasitc zip lock bags in every kit, right on top, the first thing you come to when opened...
It was to put their fingers in( never needed them, but..) Now i keep my own 3 kits [various sizes], with them in it to..
Btw , keeping one on your body, i rarley do now, but you can bleed to death in 3 mins, it might be 4 mins to do a (safe) airial rescue...
