The Adventurous Training (AT) sub aqua diving document set has recently been amended to reflect organisational changes to the Defence Safety Agency (DSA). The newly titled Superintendent of Defence Diving (SODD) has moved into the Navy Safety Centre (NSC) along with the Diving Standards Team.
A small number of typos have also been amended in both DCOP 22 and BRd 2806(5).
The current document set for Adventuruous Training (AT) sub aqua diving is as follows:
Several Suunto Zoop Novo dive computers used for AT diving have been discovered to offer reduced no-stop dive times compared to similar devices. DSM 14-18 has been released to allow similar computers to be identifed and directs that they are not to be used for AT diving.
Following several recent occasions where expeditions have received JSATFA clearance without valid laboratory gas tests, DSM 13/18 has been issued to remind single service AT desk officers of their responsibilities.
BRd 2806(5) requires all incidents to be notified to the Defence Diving Standards Team (DST) using a slightly modified British Sub Aqua Club (BSAC) incident reporting form. This form has been updated to include the latest email addresses and job title for SDSI(AT) and the JSSADC Course Clerk
The latest version of the form, and continuation sheet, can be found at this links below:
The next Joint Service Diving Safety Conference will be held on 20 Mar 2019 at HMS RALEIGH and will offer the opportunity for sub aqua divers from all 3 services to meet, share experiences and knowledge. There will be a wide range of speakers including a BSAC representative, the Superintendent of Diving, Diving Standards Officer (AT), and of course JSSADC.
There will also be the opportunity to have a Q&A session with members of the Joint Service Sub Aqua Diving Policy Advisory Committee (JSSADPAC) and a social event in the evening.
Once again we’ve laid on courses both before and after the conference:
Diving Safety Memorandum 09/18 has just been released and provides information on the impact Over The Counter (OTC) medication can have on fitness to dive. In particular there are issues with Sidenafil (Viagra) and other drugs, which cause a similar effect as PDE-5-inhibitors. These have been shown to promote the onset and severity of neurological decompression illness (DCI).
There exists a possibility for the Oceanic diaphragm style regulators sold or serviced between October 1, 2017 and May 25, 2018 with a new HP Poppet to significantly restrict airflow at low tank pressures (below 500 psi), posing a drowning hazard to consumers. Any regulator with the new HP Poppet must be fitted with the new style.

During a recent rescue drill, a defective throw line was discovered with a very low breaking strain. Riber Products Limited (RIBER) who supplied it have identified a batch of 208 throw bags which could be at risk.
To ensure that throw bag rescue lines are fit for purpose they should be opened and checked. In particular:
The entire length of the rescue line should be examined for joins or other discontinuities. This can best be done by feeling along the length of the line with bare hands to identify rough patches or lumps.
Any knots, splices or other methods of securing the ends of the line to handles, quoits or other parts of the equipment should also be checked for integrity.
The throw bag should be inspected and tried at regular intervals and repacked according to the manufacturer’s instructions, as otherwise the line may not deploy freely from the bag when required.
Any throw bag rescue lines found to have joins or discontinuities should be removed from service and the original manufacturer /supplier informed.
