These numbers are generally intended to help you initiate immediate first aid and treatment for diving accidents. If you have a question that is of a general nature, and does not involve the immediate resolution of a possible diving accident, please use the non-emergency numbers listed or call Reef Seekers directly at 310/652-4990 and we'll point you to the help you need.

IF YOU'RE ON THE WATER IN A BOAT (PRIVATE & COMMERCIAL) AND HAVE A DIVING EMERGENCY
WHICH REQUIRES IMMEDIATE ASSISTANCE OR EVACUATION:
 MARINE RADIO: Channel 16.
Call for the Coast Guard, state the vessel name and location, declare that you have a scuba diving emergency which requires immediate assistance. When USCG responds, start with the condition of your diver in distress: conscious or unconscious, breathing or non-breathing. USCG will move you to another channel, get more detailed info, and dispatch help. (It takes a while, so try to be as patient and calm as possible given the circumstances.) The L.A. County Lifeguards and the Chamber (as well as some other agencies) also monitor Channel 16 and should also hear what's going on.
IF RADIO CONTACT IS NOT AN OPTION AND YOU HAVE A CELL PHONE WITH SERVICE, USE THE EMERGENCY NUMBERS BELOW.
