如何控制underwater diving

Use a competent diving contractor, and have divers hold the qualifications and medical clearance the work requires.
Prepare a dive plan covering depth, bottom time, decompression, emergency procedures and the dive team's roles before diving.
Use a surface-supplied air system with a standby diver in place of free diving where the task allows, and keep a backup breathing gas supply.
Keep a standby diver, a dive supervisor and a surface vessel tender on duty throughout, with agreed communication signals.
Display dive flags and keep boats and other water users clear of the dive site, and tell the harbour or waterway authority.
Keep a recompression chamber and emergency oxygen within reach, and have a procedure for treating decompression illness and cold exposure.
