Scuba Diving Dangers And Risks


One of the main reasons most people don’t take part in scuba diving even with the best scuba gear packages is the risks and dangers involved such as ear barotrauma—the most common scuba diving injury.  After all, when you consider that humans are not designed for a life aquatic, the enormous pressure at great depths, and the possibility of encounters with dangerous animals, then you begin to understand where some of these fears come from.

However, it’s important to note that you will be missing out on a whole new world under the surface of the sea. Isn’t life about making the most of your experiences? When you learn how to deal with the dangers and risks involved, however, you can safely scuba dive while giving the activity the respect it deserves.

These are the scuba diving dangers and risks

Poor quality equipment

Among the most important factors when it comes to scuba diving is ensuring that the gear you are using including the scuba tanks is functioning at top form. If for example the depth gauge is broken, it might not give you the correct depth reading which can put you at risk of nitrogen narcosis.

Or assume the regulator is broken, this might cause problems breathing and in severe cases can cause you to drown.

Having equipment that is not functioning correctly is, therefore, a matter of life and death. If you are renting, check your equipment properly and thoroughly and ensure that everything is working as it should. Do not be afraid to ask for new scuba diving gear if you are not confident with the performance of the equipment.

Pulmonary embolism

Think of it this way, when a gas experiences pressure it contracts, and when the pressure is reduced it expands.

This is also true with the gas that you breathe when scuba diving. When you breathe in, the further down you go the more the pressure which means the small gasp of air will be compressed in your lungs.

When you rise, the gas in your lungs will also expand. If you were to ascend too rapidly, the gas in the lungs may expand so much that there is a risk of your lungs popping. This is a pulmonary embolism. You should, therefore, rise gradually to prevent pulmonary embolism.  Also, ensure that you never you’re your breath when scuba diving.

To allow your body to maintain its core temperature it’s crucial to wear a wetsuit.

Oxygen toxicity

This is only a risk to divers who go beyond 135 feet. Among the 7 things you should know about oxygen toxicity is that while you may not think that oxygen could be toxic, under pressure, the body will absorb a lot of the gas. Too much oxygen in your system will cause nausea, dizziness, and in extreme cases even seizures.

This can be life-threatening. If someone has a seizure at great depths, they are going to spit out the regulator which in turn will cause them to drown. To reduce and sometimes eliminate the effects of oxygen toxicity, all a diver needs to do is to gradually ascend.

However, under extreme situations, it is hard to make that conscious decision. And things are not made easier by the cold water at such depths so a dry suit and some dive gloves are nevertheless essential.

Decompression sickness


One of the most well knows diving injuries is decompression sickness. It comes about as a result of breathing in air that is under pressure at great depths. This causes the body and tissues to absorb nitrogen.

Ascending to the surface too rapidly causes the compressed nitrogen bubbles in the tissues to expand resulting in bubbles. This is decompression sickness also known as the bends.

It is extremely painful and can cause nerve and tissue damage and in extreme cases can result in death.

To prevent the bends, the diver needs to make safety stops as he ascends. The buoyancy compensator device will help you keep control as you do this.  It’s important to also observe the scuba dive table guidelines that tell you how long you can stay at different depths. Also, when making the ascent, ensure that you do so gradually.

There are however factors that increase the scuba diving risks of decompression sickness. These include your level of physical fitness, dehydration, stress, alcohol, and drug use, as well as the level of sleep that you received. It is paramount that you learn the 10 pro tips to avoid decompression sickness.

Taking proper care of your body is important. Also, make sure that you dive well within the limits recommended by the dive tables as well as the limits that you can handle as per your training. Of course, more experienced divers can go down deeper and stay under for longer.

Nitrogen narcosis

As you dive down deeper into depths of between 80 and 100 meters, you may start to feel dizzy or get a feeling of drunkenness. This is called nitrogen narcosis. In itself, nitrogen narcosis doesn’t cause any significant scuba diving dangers. However, it will affect your motor coordination, reduce your reasoning capacity, and therefore cause you to make poor choices.

Among the 18 things you should know about nitrogen, narcosis is that can cause the diver to ascend too quickly resulting in decompression sickness. This is why you will need extra training if you plan on diving beyond 60 feet.

The marine life

Most people tend to forget that every time you enter the water you are literary out of your element. It is the same as getting out into the wilds with dangerous animals roaming about.

While most marine life may not be dangerous or pose any major threat to humans, there are others such as sharks or killer whales that are a real danger. It is important to take lessons on scuba diving with sharks.

Always treat marine life with caution and respect to remain safe when scuba diving. One of the ways to do this is to have a good understanding of marine life behavior and to give some animals sharks a wide birth.


Most fatalities that occur while scuba diving are a result of drowning. There are many reasons why the diver could drown and some of them are completely unrelated to scuba diving. Another reason is diver panic. This can happen in case the diver finds himself out of the air.

The 3 scuba diving breathing techniques for beginners can be of great help.

That’s where the training comes in. By making use of the buddy system, you can share air with your diving partner and therefore prevent drowning.

One thing to always make sure of is that you should never dive unless you are in your best state of health. If you have respiratory or cardiac conditions you should consult a physician if you plan scuba diving.

When getting your dive certification, you will also get your medical checklist. Make sure you provide all the details of your previous health conditions. Note that these will not always prevent you from diving.

How to learn proper diving

Due to the scuba diving risks involved, it’s important to get proper training from a recognized program that will teach you stuff like how to prevent ear pain when diving. When you are planning on diving, one of the things that you will be required to provide is a diving certification. Otherwise, the dive shop may refuse to sell you or prevent you from renting their scuba diving gear.

You will also be asked to provide a log of how many dives you have made.

When learning how to dive, you will take several classes that teach you all about pressure at different depths, the 16 tips on how to deal with pre-dive stress, and how this affects your body. Also, you will learn how the air spaces in your body will be affected by the pressure as well as what this means when breathing through the diving regulator.

Another important lesson will be to learn how breathing compressed air affects your body as well as how to read tables.

Once you get the certification, this will not expire and can be used anywhere around the world. However, it’s a good idea to take a refresher course if you take more than 6 months between dives.
