What does diving mean?

Diving refers to sneaking in the water, and then gradually evolved into an activity below the water surface.

Diving can be divided into different types, including leisure diving, engineering diving and military diving. In daily life, people usually refer to leisure diving, that is, people dive into the water with professional equipment for entertainment and sightseeing.

Leisure diving requires divers to master certain skills and knowledge, such as how to use diving equipment, how to breathe and how to keep balance in the water. Divers usually wear diving suits and carry oxygen bottles and respirators, which can ensure that there is enough oxygen supply underwater to keep their body temperature. Divers can enjoy beautiful coral reefs, colorful fish and other marine life underwater.

Besides recreational diving, diving has other professional uses. Engineering diving refers to the underwater operations carried out by divers in the construction of water conservancy projects and tunnel projects, such as underwater welding, cutting and salvage. Military diving means that divers perform tasks in military operations, such as underwater detection, mine laying and mine clearance. These diving activities require divers to have professional skills and undergo strict training.

Precautions for diving:

1. Select and use appropriate equipment: Divers must be equipped with and master the use of diving equipment, such as diving suits, diving masks, regulators, buoyancy control devices, diving computer instruments, standby air sources (such as diving bottles), diving knives, etc. Before launching, carefully check the performance of all equipment to ensure diving safety.

2. Diving companion system and communication skills: observing the diving companion system is one of the important principles to ensure diving safety. When diving, at least two people work together to supervise and assist each other. At the same time, learn and master the underwater gesture language, so as to timely and accurately transmit information in the underwater environment where verbal communication is impossible, including but not limited to direction indication, depth signal, emergency and so on.

3. Environmental adaptation and diving planning: Before diving, it is necessary to know the environmental characteristics, water temperature, water flow, visibility and potential dangerous organisms of the diving site, and make a reasonable diving plan based on this, including diving depth, diving time, ascending and decompression scheme, etc.
