What is "tanking," in scuba diving?

The term "tanking" in scuba diving specifically refers to the improper loading or securing of scuba tanks, which poses significant safety risks. When tanks are not secured correctly, they can become dislodged and potentially cause accidents, such as falling on a diver or causing other divers to lose control of their equipment. Properly securing tanks is crucial to ensure that they remain stable and do not create hazards, especially during transport and handling.

Understanding this concept emphasizes the importance of equipment management in diving safety. It is vital for divers to check and secure their tanks before entering the water, as loose tanks can lead to serious accidents, which illustrates why maintaining proper loading techniques is critical in the diving community. The other options focus on different aspects of diving that do not relate to the risks associated with tank security.
