Scuba divers are required to adhere to the rules of scuba diving to avoid serious accidents and injuries. Divers are expected to keep their gauges clean during diving so that they don't run low on air. A low air tank can lead to decompression failure, which could prove fatal. You can inflict serious injuries if you hold your breath while diving. However, the air in the lungs expands during the ascent and contracts during the descent, so continuous breathing will not pose any problems.
Before diving, ensure you have safety precautions
Scuba divers perform pre-dive safety check before diving. A pre-dive check is a final inspection of all equipment and gear before going into the water. This can be done either from the shore or from your boat. It's a great way to inspect and adjust equipment, get familiar with your buddy and check your air supply. These are some helpful tips for performing pre-dive safety inspections.

Safety checks are performed prior to diving.
There are several safety measures that you should take before diving. You should test all of your diving equipment before you go diving. This includes your wetsuit and hoses. Also, ask your dive operator about how to use your decompression tank and emergency procedures. Your buddy should be able to use all the equipment you have, such as your tank straps or your dumps. This will enable you to know how best to safely exit the water, in case something goes wrong.
To avoid decompression sickness, ascend slowly
Decompression sickness can be avoided by scuba diving by slowly ascending and making sure to stop at or near the surface. This is a simple trick that can save you time and money. Make sure you look out for boats when you descend. Also, stay close to the dive flag. If you don't hear any boat sounds, it's safe and sound to proceed slowly.
Scuba diving requires that you always wear a snorkel
A snorkel is essential if you intend to dive in deeper waters. It allows you breathe underwater, while avoiding drowning and accidents. It is crucial to maintain good airway control. If the snorkel doesn’t fit correctly, water may leak from its mouthpiece into your lungs. You might also find some snorkels uncomfortable to wear. If this is the case, you may need to try a different style of snorkel.

Never hold your breath while scuba diving
Avoid diving if you have trouble breathing underwater. The lungs can be damaged by even a small change in depth. You can prevent your lungs from becoming too pressured underwater by making sure that your regulator is maintained in good condition. You can also try to avoid holding your breath altogether by focusing on your breathing rate. Regardless of how much you love scuba diving, you must avoid holding your breath while under water.
