Before diving, you should evaluate whether you are physically fit for diving. Be alert for signs of acute illness (such as congestion) and familiarize yourself with the risks and basic precautions associated with any chronic illness. Acute illnesses that last for more than a few days or make you feel exhausted should delay diving before diving.
- Do not dive when sick.
- Wait until you regain your normal stamina and stamina.
- Until your body is fully recovered, it is recommended to postpone diving.
- The best course of action is to consult your doctor.
- Be aware that chronic medical conditions may also affect your adaptation to the risks of diving.
- Certain unstable health conditions can put you and your potential companions at very high risk.

Don't neglect your dive plan
One of the most important steps before diving is customizing your dive plan. Learn as much as you can in advance about the dive sites where you plan to dive.
- Before you travel to a location, be sure to investigate ocean currents, depth, marine life, technology needs, boat traffic, environmental needs, health issues, and more.
- See what surface supports you may need and what local laws or regulations may apply to your planned dive.
- Inform your dive plans and arrangements to your loved ones or friends who are not involved in your trip.
- Before diving, make sure you and your buddy are in the same dive program. Discuss contingencies that occur during diving. Determine the maximum depth, maximum bottom time, and minimum air supply to terminate the dive.
- Simulate what you and your partner would do if you separated, dive, or had an emergency or equipment problem underwater. Having these discussions on the surface helps prepare the team for any situation that may arise underwater.
- Review dive gestures with your dive buddie.
- Pre-dive testing of all diving gear, especially any rented gear. Use a written or mnemonic list to ensure that no important step is missed. Do not skip partner checks.
- Develop an Emergency Action Plan (EAP). This basic tool, which divers learn how to build in an advanced training course, should include content that prompts emergency response, important contact information, the nearest medical facility and the best way to get there, and basic first aid equipment.
- Preventing and managing dive accidents in dive planning is critical.

Learn to stop diving
Calling a halt to dive has always been a psychological barrier for some divers, and anyone can pause diving at any time and for any reason. Abnormal appearance of the body due to underwater environmental factors can lead to some serious consequences. For example, depletion of breathing gas, inability to balance ear pressure, and excessive water flow can lead to decompression sickness, embolism, or neurological problems.
Stop/cancel diving principles:
Anyone can suspend diving at any time and for any reason.
Common reasons for canceling a dive:
- Environment:
- Environmental conditions can greatly affect diving activities. Various environmental factors, such as weather, can cause changes in currents, visibility, temperature and waves, which you must consider before and during the dive. Since the environment changes quickly, this can have an impact on dive plans.
- Personal Health:
- The physical and mental health of divers is essential for safe diving. Sinus or lung congestion, other body aches and pains and discomforts can cause loss of diving ability and distraction. Divers must focus their minds on the dive and their dive buddies. Distraction can lead to errors and errors in judgment, which can lead to major accidents.
- Equipment:
- Divers rely on the proper functioning of their equipment to protect their lives. A pressure gauge stuck underwater, a dive computer with a low battery, or a broken O-ring that keeps leaking can cause accidents.
- Gut feeling:
- Some things intuitively feel wrong, but you can't pinpoint exactly what the problem is, trust your instincts. Your brain will react subconsciously, your intuition is trying to tell you something, and this is the time to think deeply about whether you should continue diving.
When you find a problem, pause the dive in time, don't feel sorry for your team, know that doing so may save your life and, more likely, the lives of everyone on your team. Knowing when to stop diving is a basic skill and the hardest skill for all divers.

At last
Every diver in the dive team is equally responsible for the act of diving. When all divers understand and agree with this premise, the dive community can protect itself from individual or collective harm.
Know your personal limits and take the time to review and evaluate your diving habits, not relying on other divers in your team. As a certified diver, you should be aware of when it is beyond your training level or comfort zone.
