The Factair F2235 Dive-Check was introduced into service in 2011 to provide service AT Divers with a quick and easy method to confirm breathing gases comply with the standards set out in BS EN 12021:2014.

Seventy units were initially purchased, the majority of which were dispersed throughout the Joint Service diving community at club level. Since this time many clubs have either closed or merged, leaving some clubs with multiple Dive-Checks.

As many service divers will be aware, since this time JSSADC (well Des!) has verified and repaired equipment to enable clubs to comply with the air testing requirements laid down in BRd 2806(5). This is despite the fact that it isn’t one of our tasks nor are we funded to deliver this function.

On rare occasions dive checks cannot be repaired on a walk-in basis due to unavailability of staff or spare parts. If JSSADC held a small number of loan unit we’d be able to provide them to Clubs/ Exped thus allowing them to continue with their planned diving activities without disruption. Therefore we request that if anyone is holding Dive-Checks not required for immediate use can they please be transfer to JSSADC.

This pool of Dive-Checks is not intended to replace the ATG(A) loan pool in Bicester as the primary method to obtain test equipment for Expeds,

All divers are reminded that diving incidents and near misses are to be reported in accordance with the procedures laid down in BRd 2806(5).

Of note is that the Duty Diving Standards Officer (DDSO) is to be informed by telephone at the earliest opportunity. The DDSO number is different to the ones used by SDSI(AT) and DSI(AT) who should not be contacted, especially out of hours.

Incident reports should also be submitted in a timely fashion.

BRd 2806(5) provides details of the level of training required to crossover military (RN, RE) divers to BSAC qualifications. With the changes to the Ocean Diver syllabus some of the theory lessons no longer have the same content which means that elements are missing.

JSSADC have put together a bespoke presentation which covers the elements previously included in OT1 and OT4. It also provides additional information on JSAT diving which is likely to be relevant for military crossovers.

This presentation has now been updated to version 2 (16 Oct 19).

The presentation can be accessed by clicking this link (now at version 2). If you have any comments then please feed them back to Chief Instructor JSSADC.

A letter has just been released that provides a guide to Expedition Leaders and SADS on the role of the Diving Officer in a Diving Project. This is a key appointment that has significant legal responsibilities so it is essential that these are all completed. It is particularly important that the Diving Officer and the Expedition Leader work together to produce the Project Plan well in advance of any expedition taking place.

The letter can be downloaded at this link.

The current document set for Adventuruous Training (AT) sub aqua diving is as follows:

The master versions of these documents are located on the Defence intranet but can also be downloaded at the link above (DCOP 22 is contained in the BRd zip file).

The following points should be noted:

  • BRd 2806(5) is a large zip file (approx 10.5 MB) that will require extracting onto a local machine
  • Many of the pdf annexes in BRd 2806(5) require Adobe Reader to be viewed properly so may not work in browsers such as Safari (apple devices) or Chrome (android devices) – see below for word versions
  • Despite a request for annexes to be in word the RN policy is that they should be in pdf format.
  • The diving slate in the zip has spelling and other errors.  The one at the link below should be used.

All diving supervisors (SADS) should have a copy of these documents in their possession, be familiar with the contents and comply with the regulations within.

On occasion we are asked for word versions of some of the Annexes:

Users of AP Diving jackets with an AP200 inflator need to be aware that loosening of the plastic securing nut where the inflator hose connects can result in rapid, undemanded inflation of the BC.

To avoid this issue, nuts are to be checked for tightness when BCs are issued or withdrawn. If a loose nut is discovered then this should be passed to a qualified technician as simply tightening the nut may not resolve the problem.

In the event of an un-demanded inflation, and subsequent ascent, all are reminded of the actions that they should carry out:

  • Breathe Out – this will slow the rate of ascent and reduce the risk of a gas expansion injury
  • Disconnect Inflator Hose – using the quick release fastener
  • Dump Excess Gas – to regain neutral buoyancy.
