What is the 120 rule in scuba diving?
Here’s how it works: Your max depth (in feet) + your bottom time (in minutes) should be less than or equal to 120. That’s it. So if you plan to dive to 60 feet, the rule says you shouldn’t stay down longer than 60 minutes. For recreational scuba divers, most diving agencies recommend a maximum depth limit of 40 meters. This limit is in place for safety reasons, and diving within these boundaries is deemed relatively safe, provided recreational divers have the appropriate training and equipment.If you had but 30 seconds to teach someone to scuba dive, what would you tell them?

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. Diving does entail some risk. Not to frighten you, but these risks include decompression sickness (DCS, the “bends”), arterial air embolism, and of course drowning. There are also effects of diving, such as nitrogen narcosis, that can contribute to the cause of these problems.Individuals should not dive if they have cardiac disease that might result in incapacity underwater (e. IPO (e. DCS (e.The hazards associated with diving are death, paraplegia, tetraplegia and concussion so the outcomes of a poorly managed diving protocol in a swimming pool is severe.Scuba diving has a really good safety record and this is mainly due to the training we do before participating in our adventurous sport. All diving agencies provide training by qualified instructors in sheltered water (pool or safe shallow site) before moving their students to deeper and more exposed dive sites.Because excess nitrogen remains dissolved in the body tissues for at least 12 hours after each dive, repeated dives within 1 day are more likely to cause decompression sickness than a single dive.
