How is Scuba Diving Dangerous? 

Remember, preparedness and caution are key when embarking on underwater adventures. With proper knowledge and precautions, scuba diving can be a thrilling and rewarding experience while prioritizing diver safety. Here are the risks associated with scuba diving.

How is Scuba Diving Dangerous?
  • Decompression Sickness

One of the most well-known dangers of scuba diving is decompression sickness, also known as “the bends.” It occurs when a diver ascends too quickly, and nitrogen bubbles form in the bloodstream due to the rapid decrease in pressure. 

Symptoms may include joint pain, fatigue, dizziness, and, in severe cases, neurological and cardiovascular complications. Proper ascent rates, dive planning, and adherence to decompression guidelines are crucial to mitigate this risk. 

Divers must carefully monitor their dive profiles, ensuring ascent rates are within safe limits and following established decompression schedules to allow the body to off-gas excess nitrogen.

  • Barotrauma

Barotrauma refers to injuries caused by pressure changes during diving. It can affect various body areas, including the ears, sinuses, lungs, and teeth. Failure to equalize pressure during descent can lead to ear and sinus barotrauma, causing intense pain, hearing loss, and sinus injuries. 

Pulmonary barotrauma occurs when a diver fails to exhale adequately during ascent, resulting in lung overexpansion and potential air embolism. 

Regular equalization techniques, such as swallowing, yawning, or using the Valsalva maneuver, and proper ascent protocols, including controlled and gradual ascents, are necessary to prevent these injuries. 

Furthermore, maintaining good dental health and avoiding dental issues before diving can reduce the risk of tooth barotrauma.

  • Nitrogen Narcosis

At certain depths, divers may experience nitrogen narcosis, “the rapture of the deep.” This condition resembles alcohol intoxication and can impair judgment, coordination, and decision-making abilities. 

Nitrogen narcosis becomes more pronounced at greater depths and poses a significant risk due to impaired cognitive function. Limiting dive depths and buddy checks are essential to minimizing this danger. 

Divers should know their susceptibility to nitrogen narcosis and adhere to depth limits based on their training and experience. Additionally, maintaining good physical and mental health, avoiding alcohol and drugs, and staying well-hydrated can help reduce the effects of nitrogen narcosis.

  • Drowning

While rare, drowning is a severe risk associated with scuba diving. Equipment malfunctions, panic, disorientation, or exhaustion underwater can lead to an uncontrolled ascent or loss of consciousness, potentially resulting in drowning. 

Vigilance, proper training, and diving within one’s limits are crucial for preventing drowning incidents. Adhering to the buddy system and conducting thorough pre-dive safety checks can also help ensure the safety of divers.

Divers should maintain a calm and controlled mindset, regularly monitor their air supply, and be prepared to deploy emergency ascent procedures, such as controlled buoyant ascents, in case of equipment failure or other emergencies. 

  • Marine Life Hazards

Encounters with marine life can be thrilling, but some creatures pose potential risks. Venomous or aggressive marine animals, such as jellyfish, stingrays, or certain species of sharks, can cause injuries or stings. Divers should exercise caution, avoid provoking or touching marine life, and be aware of their surroundings to prevent dangerous interactions. 

Educating oneself about the local marine species and their behaviors, wearing appropriate protective gear, such as exposure suits or gloves, and practicing good buoyancy control can reduce the likelihood of encounters with hazardous marine life.

  • Equipment Failure

Scuba diving relies on specialized equipment to ensure safety and enable breathing underwater. Equipment failures, such as regulator malfunction, tank leaks, or loss of buoyancy control, can lead to life-threatening situations. Regular equipment maintenance, proper training, and redundant systems contribute to preventing accidents caused by equipment failure. 

Divers should have their gear inspected and serviced by certified professionals regularly, follow the manufacturer’s guidelines for maintenance and storage, and carry spare parts or backup equipment when possible. Conducting pre-dive equipment checks and practicing emergency procedures can help divers respond effectively to equipment failures.

  • Environmental Factors

Scuba diving occurs in dynamic underwater environments where factors like strong currents, poor visibility, and extreme weather can increase the risks. These environmental challenges can disorient divers, cause fatigue, and make emergency ascents more challenging. 

Monitoring weather forecasts, assessing dive conditions, and having the necessary skills to navigate such conditions are vital for diver safety. Divers should research and understand the local dive site conditions. 

Consult with experienced divers or dive operators for up-to-date information, and be prepared to adjust or cancel dives if conditions are deemed unsafe. Maintaining physical fitness, practicing buoyancy control techniques, and staying calm in challenging situations can enhance diver safety in varying environmental conditions.

How to Learn Diving Properly?

Scuba diving is an activity that requires proper training due to the inherent risks involved. Reputable dive shops will only provide equipment or services to individuals certified by a recognized agency. 

When visiting a dive operator’s shop, you must present your certification card and, occasionally, a dive log showcasing your diving experience.

  1. Join Courses to Learn about Scuba Driving

To obtain certification, most dive operations offer instructional courses based on established curricula developed by renowned organizations like the Professional Association of Diving Instructors (PADI). 

Typically, these courses require a fee ranging from 12,000 THB to 20,000 THB, depending on the location and whether the certification dives are included. The certification you receive is globally recognized and continues, although it is recommended to take a refresher course if it has been more than six months since your last dive.

A typical certification course consists of multiple classroom sessions where you will learn the fundamental physics and physiology of diving. These sessions cover the effects of changing water pressure on air spaces within your body and the air you breathe through the regulator. 

  1. Learn About the Impact of Increased Pressure 

You will also learn about the impact of increased pressure and breathing compressed air on your body. Although it may sound challenging, the course is designed to be manageable, requiring only basic math skills and the ability to read tables.

After completing the classroom portion, you will proceed to the pool to practice essential diving skills. These include setting up and dismantling diving gear, breathing through a regulator, clearing your mask underwater, and developing basic buoyancy control. Due to the numerous skills involved, you will likely have multiple pool sessions to gain proficiency.

Once you have demonstrated your understanding of the basics in the pool, you can schedule your certification dives. Typically, this involves completing four or five dives, with PADI requiring four dives and offering an optional freediving experience (snorkeling).

If you reside in a temperate climate, you may consider training with a dive operator that allows you to complete your certification dives as “referral dives.” This enables you to conduct your classroom and pool training in your local area and perform your certification dives in a more exotic and comfortable location, such as the Caribbean. Many dive operators participate in the “Universal Referral” program.

Learning to dive at a reputable dive center is crucial for becoming a skilled and safe diver. You can ensure an enjoyable and secure diving experience by obtaining proper certification and training.
