While we're on the subject of genuine risk and paranoia. I'm doing a Cavern/Sinkhole course in a few weeks. One thing I've noticed is that many of the pictures of cave divers in Aus show them using helmets. I don't know this for sure but the use of helmets seems a likely topic to arise and I may even be required to wear one (for at least some parts of a cavern course (not sure)). If this is going to be a problem I'd like to know about it. From what I've seen the WKPP don't use helmets (I assume they are not DIR and may not fit well with the system). What is the deal? I can think of a couple of possible problems right away including... 1) May interfere with deployment of long hose. 2) Obvious problems with helmet/head mounted lights (blind everyone you look at, can't hide light to look for buddies, can't signal with lights, light heads and cables (maybe canisters too) are behind your head so can't deal with problems). ....yet I imagine for abseiling into a cavern and in the dry parts under ledges, etc there is the risk of rocks/equipment falling on you. What's the deal? Any help appreciated.
