Securing dive equipment helps to prevent damage to the equipment and reduces entanglement risks, contributing to safer diving practices.
Not allowing alternate-air-source second stages, instrument consoles, and other equipment to dangle freely helps protect equipment from damage and helps reduce the risk of entanglement. Keeping equipment secured and close to the diver's body minimizes the potential for it hitting something, which could result in damage or malfunction. It also prevents the equipment from becoming caught on underwater obstacles, which could be dangerous for the diver.
Therefore, both the prevention of equipment damage and the reduction of entanglement risks are important considerations for safe diving practices.
In conclusion, not allowing diving equipment to dangle freely is a precaution that serves multiple safety functions. It keeps the equipment in good condition, prevents accidents, and ensures that divers have a safe and unobstructed experience underwater.
