cool- I finally get to contribute something. I just went to Diver's Safety Day here in LA and a panel of 'experts' including those that actually respond here in a diver emergency (coast guard pilot, swimmer, Chamber admin, deco doctor, sherriffs, lifeguards, etc) had this discussion for us. I came up with the following idea based on their discussion. Here goes...
Having 911 on the dashboard isnt enough. 911 goes through the Highway patrol and will eventually be routed to the right people. Its so much more direct to have a flip chart in the glove box of the local numbers for each dive site you frequent, so you can communicate directly. Numbers you need to consider are the local lifeguard service, coast guard, 911 and Dan. Its also good to have a little script written on the front page of what to say in case you get rattled or need to send someone else to make the calls at a nearby pay phone/ phone box. You need to know where that is before you get in the water and check to see if the cell phone service is working. Remember the key words Scuba Diving Emergency. If you call 911 a diving emergency could mean off a diving board into a swimming pool to them.
