Detailed Recreational Diving Standards Check (RDSC) Report

UNIT:    RAFSAA Adventure              DATE:       9 – 13 Mar 09        OVERALL ASSESSMENT:                  PASS
         Training Centre
SUMMARY: This was the second visit from the Diving Standards Team (DST) to the Royal Air Force Sub Aqua Association (RAFSAA)
Adventure Training Centre Ascension since the post was manned in June 07. On completion of the last RDSC to Ascension DSO(AT) was
concerned about the remote location of the island and lost diver location if an incident occurred. It was recommended that an EPIRB system
operating on 406 Mhz which links to a satellite system be introduced. This action has been carried out and a simulated ‘lost diver’ exercise
was conducted during the RDSC. Also the loading and unloading of the dive boat at Guana jetty remained a safety issue. RAFSAA are in the
process of producing a ‘demonstration’ video which shows the correct method of loading a dive boat which will be incorporated into the arrival
brief given to joining expeditions. This is especially important to expeditions which have not used the centre before.

The Ascension Island RAFSAA AT centre holds 24 diving cylinders and weights for visiting expeditions. All the cylinders were found to
be in date and good condition. The master file with all test dates and cylinder records are held by Sgt Marshall at RAF Benson. The 3
monthly grab test unit which is used to carry out the air analysis (Factair 3000) was also in date and in good condition. This will require
having an air sample carried out in accordance with JSP319 when the 2 CNBA compressor samples are sent to a UKAS laboratory for
analysis. This is to confirm the accuracy of the unit. Sgt Marshall has samples taken for him from the CNBA and the results are
forwarded to him for trend analysis. The AT centre also holds x 4 Humber ‘A’, x 1 Humber 16 I & X 1 Avon 525 craft. These are all
maintained to a very high standard along with the outboard engines (OBM). Considerable time and effort is spent maintaining this
equipment by Sgt Marshall and his works parties. During the RDSC the team that DSO(AT) saw on average were still wor king until late
into the evening getting the equipment ready for the first incoming exped. Sgt Marshall and his works parties are to be commended for
the hard work that is often not seen by the visiting SADS and expeds.
