Scuba diving is inherently hazardous. The risks associated with the sport are mitigated through a number of controls and adherence to the guidelines laid by the British Sub Aqua Club. The BSAC training program as laid down in the Instructor's Handbook is designed to minimise this risk through a sequence of progressive lessons _ both theory and practical _ to build up the necessary skills in a progressive and structured manner.
Generic risks that are addressed through the standard diving training program include:
Ear damage, mask squeeze, buoyancy control, equipment failure, running out of air, diver separation, poor technique(s), decompression illness, pre-dive equipment checks...
Further risks due to poor practice are addressed through adherence to the BSAC publication "Safe Diving Practices" and The Combined Diving Associations publication "Guidelines for the safe operation of member club dive boats".
All diving operations take place under the control of a qualified Dive Marshal. The responsibilities of the Dive Marshal include the on-site risk assessment, ensuring divers are suitably qualified/equipped/experienced for the dive to be undertaken, the conduct of the dive (depth/duration), assignment of buddy pairs and pre-dive briefings.
Formal Risk Management is a relatively new activity for amateur Sub-Aqua clubs such as Sunstar Sub-Aqua. The important aspect of the activity is not the risk analysis itself, but the set of controls, diving practises and club recommendations which will be applied as a consequence of the risk analysis, in order to further improve safety over existing controls as listed above.
This process is continuous rather than atomic and as such will be subject to review as determined by the club committee. An initial draft is now in place. Controls for pool use and training are already applied now. Controls and recommendations for diving operations, together with the control mechanism that is yet to be determined (probably a new marshal checksheet), will be reviewed by the Sunstar Diving Sub-Committee and a final version will be in place before the commencement of open-water diving at the end of March 2005.
In the following sections the significant risks associated with specific activities are identified. These are subdivided into:
Pool
Sunstar hires the Fore Street pool from Ipswich Borough Council. The pool is used for general swimming, snorkelling and diver training. Qualified divers may use the pool to check out new pieces of equipment and to refresh their basic skills. Two IBC lifeguards are present.

The boat must be equipped with suitable navigational aids (GPS, Compass, Charts) and carry VHF radio(s) for contact with the Coastguard. A First Aid Kit and 02 set must be carried as well as people competent in their use. A passage plan must be prepared.
