Which of the following is an example of a diving hazard that must be reported?

A trapped diver requiring assistance is a significant diving hazard that demands immediate attention and reporting. This situation poses a serious risk not only to the diver who is trapped but also to the overall safety of the diving operation. When divers encounter critical issues, such as being trapped, it is vital to communicate this information to ensure that appropriate rescue procedures can be initiated. Reporting such incidents supports the safety of the diving team and enhances collective awareness around potential hazards present during diving activities.

In contrast, standard diving operations, successful completion of a dive, and uninterrupted equipment operation are aspects of diving that do not indicate immediate risks or hazards requiring reporting. These conditions are considered part of routine operations and do not present safety threats or emergencies that necessitate intervention or communication. Therefore, they do not fall under the criteria for reporting hazards within the context of diving safety protocols.
