Divers and Snorkelers must always use red and white "diver down" flags to alert boaters of
their presence. Boaters should know that the Keys have many shallow areas. They also should
pilot their craft at reasonable speeds, especially in channels and harbor areas.

All precautions should be taken to avoid decompression illness, but if illness is suspected the
hospital staffs in the Keys are very experienced with diagnosing and treating it.  Divers
suspecting decompression illness should seek medical attention immediately at one of the
Keys hospitals The staff at these facilities know how to diagnose and treat the condition. If
necessary, they will transfer patients to one of two decompression facilities in the Keys. The
U.S. Military operates a decompression chamber in Key West. The more-often used facility is
located in the Upper Keys at Mariner's Hospital

In an emergency, dial 911 from any phone in the Florida Keys.

In an emergency, dial 911 from any Florida Keys land or cellular phone. In case of a boating
emergency, dial 911 or contact the United States Coast Guard, via Channel 16, on a marine
