4. Is SCUBA Diving in Krabi dangerous?
SCUBA Diving in general carries with it inherent risks, but for 99.9% of divers there is no worry as long as you follow a number of safety procedures. Check your equipment and dive with your abilities you have nothing to worry about. Here is a short list of things to consider before you take to the great blue.
Never hold your breath – When you descend in water your lungs act like a sponge contacting under pressure and expanding when pressure is released. Water applies pressure to your lungs and the greater the depth the greater the pressure. We all known that when you breathe in air expands the lungs and when your breathe out your lungs shrink. When you’re SCUBA Diving it’s important to always be breathing therefore allowing excess air to escape when pressure is added or taken away. If your hold your breath during SCUAB Diving and you are in the process of ascending the lungs will overextend because the pressure will not be able to escape. In the unlikely event of holding ones breathe there is a chance of damaging lungs due to over-expansion, a condition not to be taken lately, so please always remember to breathe.
Ascend slowly – When your are SCUBA Diving there is an exchange of pressure and gasses between the blood stream. One of these gases is Nitrogen and with Nitrogen making up some 70% of the gas we breathe in, there is a lot of it. When a breath is taken in this Nitrogen under pressure is absorbed into the blood stream, then you ascend slowly much of this nitrogen is allowed to slowly come out fo solution. In the event that you ascent too fast from a depth there is a chance that the Nitrogen in the bloodstream can consolidate under the skin creating small pockets of gas. This is one of the causes of the infamous ‘Bends’. This can all be avoided by ascending at a rate no faster than 30 feet (10 meters) per minute. Always make sure to make a safety stop at 15 feet (5 meters) to ensure all excess Nitrogen is given time to come out of the blood stream at a safe rate.
Check your gear – SCUBA Diving in Krabi is not possible without SCUBA Diving equipment, therefore treat it with respect. Always check the air in your tank, check the weights on your BCD, make sure your buddy’s gear is also in order. Always check that you take a look at their equipment, in fact the vast majority of equipment related accidents do not occur to equipment malfunction, they occur due to the divers not knowing how to use the equipment. Depending on your dive check equipment pertinent to that dive, for example if your going on a night dive, make sure you have a Primary and back up torch. If your going on a nitro dive, make sure you’re tank is properly mixed with the correct proportions of nitrogen. If you’re going on a 2 tank dive, make sure both of your tank are filled properly and connected securely.
Stay Fit and hydrated – SCUBA Diving is a physically demanding sport. It’s a sport that takes a toll on anyones body, therefore it’s always best to treat your body the best that you can in order to ensure it will take care of you on a dive. Go for a job, eat healthy in general. Get a good nights sleep and don’t drink the night before going out SCUBA Diving in Krabi. Also it’s recommended to drink plenty of water before and during SCUAB Diving in Thailand. Avoid cigarette and coffee while diving as much as you can, and if you’re not feeling good in between or before dives take a rest and don’t push yourself.
Dive within your limits – Depending on your experience, your certification and your ability there are certain depths and dives you are able to go on. It’s important that you take that seriously and don’t go beyond your ability. If your an open water diver capable of SCUBA Diving to 18 Meters in depth and have dived to 18 meters before, but the dive your about to go on can go to 40 meters, make sure you tell the dive master or dive instructor of your level and ability. All dive masters and dive instructors will ask during the dive briefing what all divers certification level are. Don’t push yourself it’s often the case for many dive related accidents when divers go above and beyond their ability to try and show off.
Follow the rule of thirds – Always dive with safety in mind. When thinking of safety and time management make sure you’re planning ahead in all times. There is a simple rule call the of theirs which lines out that the beginning of a dive or outward journey should have 1/3 of the air reserve allocated for this purpose. The return journey should also have 1/3 of the air supply allocated for this part of the trip. Finally the ascent should have 1/3 of the air supply allocated for this purpose. Leaving 1/3 of the air supply for a safe ascent and giving enough time for the safety stop will ensure that the bends can be avoided and and unforseen issues which can arise can be dealt with with amply air.
Plan your dive and dive your plan – Every dive site is different, every dive site required certain knowledge and understanding, thats why it’s always best to go SCUBA Diving in krabi with a professional knowledgable dive operator. Someone who lives and dives the dive sites of Krabi daily and knows each and every place like the back of their palm. Prior to every dive the dive master or dive instructor will go over the dive site in detail. Alerting all divers of anything needed to know about regarding currents, depths, swim-throughs and such. It’s important that every dive is planned (by the dive master or dive instructor) and that all divers listen and ask questions about the dive and moreover understand the plan for the dive site. It’s important that all divers understand the dive plan and stick to it.
Use the buddy system – SCUBA Diving in Thailand and the world for that matter recommends that all SCUBA Divers dive with a buddy. There are unforeseeable events which can occur during a dive it’s always important that you have a second diver with you who can assist in case something happens. When you are diving with a buddy whether it be a friend or someone who was assigned to you by the dive instructor it’s important that you talk with them, alert them of any particular equipment or dive issues you might have prior to descending into the water.
