What is the 120 rule in scuba 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. A 3-minute safety stop in diving is a pause at a depth of 5-6 metres for three to five minutes, allowing the diver’s body to decompress and unload nitrogen accumulated during the dive. It is an important part of the safety procedures for all dives below 10 meters.Some recreational divers have descended to depths of 1,000 feet and beyond and survived the experience without any problems. However, the biggest concern is getting crushed from the increasing weight of the water. The water pressure can suffocate you to death if you don’t take precautions.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.A diver at 15 feet of saltwater, typically, can stay indefinitely with almost no chance of decompression sickness while a diver at 60 feet can only remain for about an hour before needing to stop and decompress prior to direct return to the surface.That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6. Experienced divers can safely dive to a depth of 40 feet (12.
What is the 1/3 rule in scuba diving?
In technical diving, the 1/3 Rule ensures divers have enough gas for the descent, return, and emergencies. It divides the total gas supply into three parts: one-third for the descent and exploration, one-third for the return, and one-third as a reserve, enhancing safety in challenging environments. The Rule of Thirds is a guideline used by scuba divers to manage their air supply effectively throughout a dive. It involves mentally dividing one’s breathing gas supply into three equal parts. One-third for the outward journey, one-third for the return journey, and one-third as a reserve or emergency supply.
