Which of the following is NOT a typical item that must be tagged out before a dive operation?

In the context of dive operations, tagging out involves identifying and ensuring that specific equipment is properly secured or made inoperable before diving activities commence. This procedure is crucial for maintaining safety during dives.

Life rafts are not typically tagged out before a dive operation because they are essential safety equipment used for emergency situations. In contrast, items such as anchors, sonars, and suction systems are more directly involved in the operational aspects of the dive itself, which may require more stringent safety protocols to prevent accidental activation or mishandling.

Anchors can pose risks if they are not secured, as they may cause entanglement or inadvertently affect the dive environment. Sonars may need to be tagged out to prevent underwater noise disruption that can affect marine life or diver communication. Suction systems also require tagging to ensure they are not mistakenly activated during the dive, which could lead to hazardous situations.

Thus, life rafts, being crucial for diver safety rather than operational tasks, are not part of the tagging out procedure, making them the correct choice in this context.
