Five basic rules for cave diving safety that must be followed by every diver are:
- Always use a continuous guideline to the surface.
- Save two-thirds of the total air supply for returning to the surface.
- Carry at least three lights during the dive.
- Limit dive depth to that appropriate for the gas being breathed.
What is the most important rule when scuba diving?
Never hold your breath.
This is undoubtedly by far the most crucial of all safety rules for diving because failure to adhere could result in fatality. If you hold your breath underwater at the depths at which scuba divers reach then the fluctuating pressure of air in your lungs can rupture the lung walls.
What are the basic rules of diving?
The Six Rules Of Scuba Diving
- Breathe continuously while on scuba. Never hold your breath.
- Equalise early and often while descending.
- Ascend slowly from every dive and make safety stops.
- Continuously monitor depth, time, and pressure.
- Do not overweight yourself.
- Dive like a fish (and not like an ape).
What are the three basic rules of scuba?
Good rules to follow for safe diving include: Never dive without a buddy. Never dive if you have a cold or are congested in your ears or nose. Always plan your dive, and always dive your plan.
What is the first rule of diving?
Always breathe continuously. Never hold your breath. As I mentioned earlier, this is arguably the “number one rule” of scuba because breath holding while scuba diving can lead to serious injury, even death.
Why do divers hold their hands?
The above water: As divers approach the water, they must extend their body into a rigid, straight line. Importantly, they must put their hands one on top of the other with flat palms, to create what’s called a rip entry (named because it sounds like a piece of paper is being ripped as the diver hits the water).
Why can’t you hold your breath when diving?
The air in your lungs becomes unsafe when you ascend. If you hold your breath while ascending to the surface, your lungs and the air within them expand as the water pressure weakens. Since that air has nowhere to escape, it keeps swelling against the walls of your lungs, regardless of the organ’s finite capacity.
What are the 6 types of dives?
Each of the dive groups is represented by a number in competition:
- Forward Dive – 1.
- Backward Dive – 2.
- Reverse Dive – 3.
- Inward Dive – 4.
- Twisting Dive – 5.
- Armstand Dive – 6.
Can you swallow while diving?
Since you can’t exhale anymore if you’re equalizing using your throat, not exhalation. Many divers can also equalize by swallowing, wiggling or stretching their jaws (not easy with a regulator though) or a combination of these. You can also swallow while pinching your nose.
What is a 5 point ascent?
This skill is best remembered by using the acronym STELA: Signal, Time, Elevate, Look up, Ascent. In order to demonstrate this skill, follow these steps: Give the skill signal for the five point ascent. The first point is to signal to the buddy that it is OK to go up and all are ready to ascend.
What are the 10 steps to scuba diving?

- Practice safe ascents.
- Check your gear.
- Dive within your limits.
- Stay physically fit.
- Plan your dive; dive your plan.
- Rule of thirds.
- Use the buddy system.
What should you never do while scuba diving?
During Your Scuba Diving Trip
- Never Hold Your Breath – Breathe Normally.
- Equalize Frequently as You Descend.
- Stay Aware of Where Your Guide and Buddy Are.
- Keep an Eye on Your Air Gauge.
- Dive Within the Limits of Your Dive Computer and No Deeper Than 40m.
- Don’t Over Exert Yourself.
- Don’t Touch Anything.
What is safety stop in diving?
A safety stop is a standard dive procedure that is done in scuba diving for any dives below 10 meters (32 feet) This brief 3 to 5-minute pause at a depth of 5-6 meters (15-20 foot) is a practice which allows a diver’s body to decompress after time spent at depth.
What depth is safe for diving?
The American Red Cross recommends a minimum of 9 feet of water depth for head first dives including dives from pool decks. Results for a comprehensive study of diving injuries are presented in “Diving Injuries: The Etiology of 486 Case Studies with Recommendations for Needed Action” edited by Dr.
What is a no-stop limit in diving?
The “no-decompression limit” (NDL) or “no-stop limit” , is the time interval that a diver may theoretically spend at a given depth without having to perform any decompression stops while surfacing.
Which is done after a dive?
Get a light massage
After diving you may have sore muscles from swimming for prolonged periods. A light massage is great for relaxing your muscles and can even help to release smaller nitrogen bubbles. However, you should never have a deep tissue or any other kind of strong massage.
Why do female divers touch their stomachs?
But as it turns out, it’s just a way to relax and keep warm, according to Canadian diving coach Mitch Geller.
Why do divers shower after every dive?

Why do divers throw a towel?
“It is not a toy, but a professional thing that is necessary for the preparation of the dive. You need to take off the liquid so you don’t lose your body position when you are spinning,” Evgenii Kuznetsov (RUS) added.
Do your lungs shrink when you dive?
As external pressure on the lungs is increased in a breath-holding dive (in which the diver’s only source of air is that held in his lungs), the air inside the lungs is compressed, and the size of the lungs decreases.
What does Bent mean in diving?
DCS, also known as the bends, describes a variety of injuries that result from inadequate decompression following exposure to increased pressure. This can occur following uneventful dives within accepted no-decompression limits but is more likely after dives that involve a rapid underwater ascent.
