Boyle’s law explains some of the most important safety rules in scuba diving. … Ascend Slowly – A diver’s body absorbs compressed nitrogen gas while he dives. As he ascends to a depth with less water pressure, this nitrogen gas expands according to Boyle’s Law.
How it can help divers stay safe underwater?
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.
- Check your diving equipment to make sure it works. …
- Do not drink alcohol or take drugs before diving.

How do gas laws affect scuba divers?
The implication of this law for SCUBA diving is that as depth increases (and therefore pressure) the amount of a gas dissolved in the diver’s blood will also increase. … When the diver ascends the partial pressure of nitrogen drops, and due to Henry’s law the dissolved nitrogen begins to come out of solution.
How does the behavior of gases affect a scuba diver underwater?
“The bends” are even scarier. As you come to the surface from a dive, nitrogen gas can bubble up in your body like carbonation in a freshly opened can of soda. If you swim up too fast, decreasing pressure makes the bubbles expand, which can cause severe pain in your joints and create other problems in your body.
How does Charles Law relate to diving?
Charles’ Law states that at a constant volume, the pressure of gas varies directly with absolute temperature. … The gas in a SCUBA tank reacts the same way to temperature as air in a balloon. However, the walls of a tank are rigid with little to no flex, while the elasticity of a balloon allows it to expand.
What is the most important rule in scuba diving?
If you remember one rule of scuba diving, make it this: Breathe continuously and never hold your breath. During open water certification, a scuba diver is taught that the most important rule in scuba diving is to breathe continuously and to avoid holding his breath underwater.
Why is the Blue Hole dangerous?
The Blue Hole itself is no more dangerous than any other Red Sea dive site but diving through the Arch, a submerged tunnel, which lies within the Blue Hole site, is an extreme dive that has resulted in many accidents and fatalities. … This includes some snorkelling deaths at the surface unrelated to diving the Arch.
What are the dangers of scuba diving?
The dangers and risk of scuba diving
- Decompression Sickness. This might be the risk of scuba diving that most people talk about. …
- Drowning. Even if Decompression Sickness is the most common risk of scuba diving to talk about, there are more drowning accidents within the diving community. …
- Malfunctioning Equipment. …
- Nitrogen Narcosis. …
- Marine Life.

Why is it dangerous for a diver to take a hot shower?
Exposure to warm or hot water after scuba diving can cause peripheral vasodilation and sudden discharge of even massive quantities of nitrogen bubbles into the venous circulation, with increased risk of DCS. Exposure to warm water (hot bath, showers etc.)
Why is Charles law usually irrelevant to scuba diving?
Charles’ Law does not relate to scuba diving. Charles’ Law is often used to explain why the pressure in a scuba tank goes up when the temperature increases. But Charles’ Law states that the volume of a gas is directly proportional to its temperature. The volume of a scuba tank is constant.
Why do divers exhale when surfacing?
As the diver ascends, the air in the lungs expands as surrounding water pressure decreases. Exhaling allows excess volume to escape from the lungs, and by exhaling at a suitable rate the diver can continue exhaling throughout the ascent and still have air in his or her lungs at the surface.
Why do scuba divers use nitrogen?
When you scuba dive, the longer you stay under the water (bottom time), the more nitrogen your body absorbs. If divers absorb too much nitrogen in their blood stream, they develop a condition known as “the bends” (also known as decompression sickness). … This is common and part of the diving experience.
Why is it dangerous for a scuba diver to move up rapidly to the surface of water?
Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. … And if a diver rises to the surface (decompresses) at the right rate, the nitrogen can slowly and safely leave the body through the lungs.
Which gas law would most affect scuba divers?
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. Without doubt, understanding Boyle’s Law is very important in scuba diving. Note that Boyle’s law also relates to gas density.
Why do divers use helium?
The main reason for adding helium to the breathing mix is to reduce the proportions of nitrogen and oxygen below those of air, to allow the gas mix to be breathed safely on deep dives. … Helium has very little narcotic effect. A lower proportion of oxygen reduces the risk of oxygen toxicity on deep dives.
Why do free divers never have to worry that their lungs will rupture if they surface at a fast pace?
With a single breath there is no air in and out of your blood and tissue when free diving. … Why do free divers never have to worry that their lungs will rupture if they surface at a fast pace? Because the air volume in their lungs never exceeds what was there when they inhaled and started the dive.
