Why must a scuba diver ascend slowly from a dive?

How do you ascend slowly when diving?

SLOWLY KICK AND SWIM UP

When you are ready to ascend, hold your inflator hose in your left hand and have your finger on the deflate button. You should start to kick up slowly, while continuously releasing air from your BCD. This stops the air in your BCD from expanding too much and pulling you up too quickly!

What happens if you descend too fast while diving?

There are many reasons for learning to descend properly. 1- Descending fast can to lead to the risk of squeezing out air spaces in our ears. We need to descend slower to allow air spaces, such as in our ears and mask, enough time to equalize as the pressure changes.

Why must deep sea divers slowly swim to the surface Why is it important for them to have knowledge of Boyle’s Law?

As he ascends to a depth with less water pressure, this nitrogen gas expands according to Boyle’s Law. If a diver does not ascend slowly enough for his body to eliminate this expanding nitrogen gas, it can form tiny bubbles in his blood and tissue and cause decompression sickness.

When scuba divers are rising after a dive Why is it important that they do not hold their breath?

When the diver surfaces- one of the most important rules is to be continuously breathing. Never hold your breath when ascending. This is due to the air in the lungs will start to expand because there is less pressure of the water exerted on the body. Holding your breath can cause catastrophic injury to divers lungs.

Why can’t divers ascend quickly?

Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. … But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage.

What happens if you fart while scuba diving?

Farting is possible while scuba diving but not advisable because: Diving wetsuits are very expensive and the explosive force of an underwater fart will rip a hole in your wetsuit. An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness.

Why is it important for a scuba diver to return from the deep water to the surface slowly use the gas laws to help you explain?

Safe divers return to the surface at a slow pace to minimize the risk of decompression sickness, and they observe the no-fly rule to give their bodies time to release any accumulated nitrogen before undergoing rapid altitude changes.

Why a scuba diver needs a diving tank while he is underwater?

A scuba diver needs a diving tank in order to provide breathing gas while he is underwater.

Boyle’s Law

As a diver, Boyles law affects you every time you enter the water. Air spaces in the body are subjected to pressure and volume change, in direct proportion to your depth. … This part of the law becomes particularly important on deep dives; inhaled air will become denser the deeper one goes.
