What is the golden rule of 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. Underlying respiratory conditions (e.Medical Reasons A Person Should Not Dive Disorders that can impair consciousness, alertness, or judgment, such as seizures and diabetes that is treated with insulin (because it can cause low blood sugar levels [hypoglycemia]) generally preclude diving. Special programs for divers with diabetes have been established.You’re sick, injured, or just not 100% If you’re sick or injured, it’s simple: don’t dive! You should feel your best (or close to it) before you commence any diving activities. Diving physiology gets complex when you are congested or are experiencing other symptoms that may merely be a nuisance on the surface.Often called the bends, decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues. This doesn’t cause a problem when a diver is down in the water.
What are the 4 positions in diving?
Diving positions for platform and springboard diving are based on four distinct shapes. These are straight, pike, tuck, and free. During competitions they are referred to as A, B, C, and D. There are 5 basic categories or groups of dives for spring board diving. The first four are named according to the direction of the dive relative to the diving board. These are forward, backward, reverse, and inward. The 5th category can be done in any of the 4 previous positions, but involves a twisting component.Dives can all be put into one of six categories: forward, backward, reverse, inward, twisting, and armstand.In springboard and platform diving, there are four different body positions: Tuck, pike, layout, and free. For every dive, a diver will choose what body position the dive will be performed in.There are six groups into which dives are classified: Forward, Back, Inward, Reverse, Twist, and Armstand.
What is diving law?
Boyle’s law: P1V1 = P2V. A fundamental rule of SCUBA diving is to never hold your breath. A look at Boyle’s law explains why this rule exists. When a diver inhales air from a SCUBA tank, the air that enters the diver’s lungs is at ambient pressure. The most important rule in scuba diving is to always breathe continuously and never hold your breath to avoid lung over-expansion injuries. Another important rule is that divers should ascend slowly and safely to prevent decompression sickness.The Rules of Scuba Diving: Never Hold Your Breath. Plan Your Dive. Dive Within Your Limits.It’s important to maintain a slow and rhythmic breathing pattern while diving. Breathe fully (deeply) but keep it easy and relaxed. It shouldn’t feel as though you are ‘sucking’ the air out of the tank or forcing it out through your mouth.A mask lets you see clearly. A scuba regulator and tank provide the air you need. Fins allow you to swim efficiently, and a wetsuit helps you stay warm. Whether you’re just starting as a scuba diver or you’re an experienced diver looking for new equipment, you’ll find helpful suggestions and tips in this section.
What are the 5 categories of dives?
There are 5 basic categories or groups of dives for spring board diving. The first four are named according to the direction of the dive relative to the diving board. These are forward, backward, reverse, and inward. The 5th category can be done in any of the 4 previous positions, but involves a twisting component. All dives are categorized into five main groups: Forward, backward, reverse, inward, and twisting. There is also a sixth group in platform diving: The armstand group. Every group of dives is assigned a number.
