What is the golden rule of diving?
Never hold your breath. This is undoubtedly by far the most crucial of all safety rules for diving because failure to adhere could result in fatality. 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. It is concluded that the impact of diving on pulmonary function largely depends on factors associated with the individual diving exposure. However, in susceptible subjects clinically relevant worsening of lung function may occur even after single shallow water scuba dives.
What is the 120 rule in diving?
The rule advises that the dive depth (in feet) in addition to the time a diver spends underwater (in minutes) should add up to no more than 120. The purpose of this rule is to help scuba divers to avoid serious dangers such as nitrogen narcosis as well as decompression sickness by keeping them within a safe range. 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.The American Red Cross recommends a minimum of 9 feet of water depth for head first dives including dives from pool decks.The rule suggests that the depth of the dive (in feet) and the time spent underwater (in minutes) should not exceed a combined total of 120. The goal of this rule is to keep divers within a range where they can avoid serious risks such as nitrogen narcosis and decompression sickness.Lap Swimming: A consistent depth of around four feet is ideal for swimming laps. Family Use: A minimum depth of three feet ensures safety and enjoyment for both kids and adults. Diving: At least eight feet of depth is necessary to prevent injuries for diving enthusiasts.The rule advises that the dive depth (in feet) in addition to the time a diver spends underwater (in minutes) should add up to no more than 120. The purpose of this rule is to help scuba divers to avoid serious dangers such as nitrogen narcosis as well as decompression sickness by keeping them within a safe range.
