uk admin vps recall as a kid my mother cooking with a Pressure-Steamer, I was always fearful the stress would explode the sealed pot so I typically hid away from the sight, what I did not realise was the lid had a constructed in security device. This is equivalent to diving in that there is a risk of insignificant nitrogen “Off-Gassing” throughout our ascents.
Diving has mostly normally been about Decompression, from day one the concerns of curing or to be additional truthful stopping Decompression sickness has often been the leader in Dive accident prevention. Although dive Tables and Pc Models are primarily based on theoretical dive information, there is nevertheless some element of risk and the only way to protect against Decompression Sickness is to not dive at all. Even so there are also Lions in the Jungle, all we can do as educated and protected divers is to guarantee these risks are at kept to their minimum.
Avoiding Decompression sickness is to remain hydrated, drink plenty of fluids avoiding alcohol both ahead of and after diving, and using re-hydration salts particularly when diving in hotter climates. Stay clear of strenuous workout during and following a dive, dive effectively inside recommended limits and ensure both Actual Bottom Time and ascent rates are adhered to. The suggested price is 18 metres in 60 seconds, with a 5 metre safety stop exactly where applicable. Personally I would advocate a security stop after ALL dives regardless of no matter whether the RDP (recreational Dive Planner) deems it essential. With regards to the encouraged ascent price, once more I would suggest that slower is improved – the way I recommend this is to think about your dive profile as a stepping method – attain your pre-planned depth for the pre-planned time and then stage your ascent to unique levels i.e. 26 metres Max Depth for 12 minutes, the next stage would be 18 metres for four minutes then 8 metres for 4 minutes then five metres for four minutes – your ascent price 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 recommended price of 1 minute. This gives us lots of time for the nitrogen in your physique to “Off-Gas”.
As a accountable diver also assure you are aware of the emergency action plan and have information of the nearest Hyperbaric Chamber, have get in touch with information for rescue contacts etc. do not rely on other people having this information they may well be considering the similar about you bear in mind.
Think Moving not Stationary
A safety cease, even though defined as five metres for three minutes, can and should be extended exactly where feasible consider a five metre cease for eight minutes, you do not have to be stationary! Maintain moving to your planned exit point enjoying the fantastic sights at this level and your dive will be both much more enjoyable and safer. Usually most reefs have an abundance of life and colour at these shallower depths, remember orange and red are the very first colours of the light spectrum to disappear as we descend.
