Diving and Decompression – The risk you take

I don’t forget as a child my mother cooking with a Pressure-Steamer, I was constantly fearful the stress would explode the sealed pot so I often hid away from the sight, what I did not realise was the lid had a built in security device. This is equivalent to diving in that there is a risk of insignificant nitrogen “Off-Gassing” during our ascents.

Diving has mainly normally been about Decompression, from day one the concerns of curing or to be much more truthful stopping Decompression sickness has often been the leader in Dive accident prevention. While dive Tables and Computer Models are based on theoretical dive data, there is nonetheless some element of threat and the only way to protect against Decompression Sickness is to not dive at all. Nonetheless there are also Lions in the Jungle, all we can do as educated and safe divers is to assure these risks are at kept to their minimum.

Avoiding best rdp is to remain hydrated, drink plenty of fluids avoiding alcohol both ahead of and just after diving, and employing re-hydration salts specially when diving in hotter climates. Stay away from strenuous physical exercise through and immediately after a dive, dive properly inside encouraged limits and make sure each Actual Bottom Time and ascent prices are adhered to. The advised price is 18 metres in 60 seconds, with a 5 metre security cease where applicable. Personally I would advise a security cease after ALL dives regardless of no matter whether the RDP (recreational Dive Planner) deems it needed. With regards to the encouraged ascent rate, once again I would recommend that slower is improved – the way I suggest this is to look at your dive profile as a stepping method – reach your pre-planned depth for the pre-planned time and then stage your ascent to different levels i.e. 26 metres Max Depth for 12 minutes, the next stage would be 18 metres for four minutes then eight metres for 4 minutes then 5 metres for four minutes – your ascent rate to every distinctive level of the dive will be both slow and controlled. This example would give you an ascent time from 18 metres of 12 minutes as opposed to the advised rate of 1 minute. This gives us a lot of time for the nitrogen in your physique to “Off-Gas”.

As a responsible diver also guarantee you are aware of the emergency action program and have particulars of the nearest Hyperbaric Chamber, have speak to information for rescue contacts etc. do not rely on other individuals possessing this info they may perhaps be thinking the similar about you remember.

Consider Moving not Stationary
A safety cease, although defined as 5 metres for three minutes, can and ought to be extended where feasible consider a five metre cease for 8 minutes, you do not have to be stationary! Keep moving to your planned exit point enjoying the superb sights at this level and your dive will be both additional enjoyable and safer. Typically most reefs have an abundance of life and colour at these shallower depths, don’t forget orange and red are the 1st colours of the light spectrum to disappear as we descend.
