What precaution should be observed when diving with an empty tank?

The most responsible and safest approach to diving with an empty tank is to refrain from entering the water altogether and to ensure that divers are equipped with a fully functional, filled tank. An empty tank poses a significant risk, as it would leave a diver without a primary breathing gas source underwater, which can quickly lead to life-threatening situations such as drowning or severe panic.

Diving requires careful planning, and ensuring that all equipment is in optimal working condition is crucial. A filled tank provides not only the necessary air supply but also peace of mind, allowing divers to focus on their tasks rather than worrying about their safety. This principle underlines the importance of pre-dive checks and proper safety protocols. Entering the water with an empty tank disregards these essential safety practices and can have dire consequences, emphasizing the critical nature of this precaution.
