· Advise the distressed diver what is about to happen. Provide reassurance.
· Write down the dive profile to give to the winch-man. Include diver's details
· Continually monitor the diver's condition.
· Identify a large clear area for winching.
· Clear away all non-essential personnel.
· Be ready to communicate with the helicopter on VHF Channel 16 or 67.
· Have orange smoke ready to identify your position to the helicopter· Dive computers will also be of value to recompression facilities.
· More often than not, dive buddies will also be evacuated.On Arrival:
The helicopter crew will assess your craft for safe winching operations. If it is safe, do exactly as requested. You may be required to lower aerials, to get underway at slow speed or to receive a weighted rope. Whichever method is used, it is important that you follow the instructions given.Do not touch the winch-man, winch wire or weight unless indicated by the winch-man.
