What attire is required for aquatic staff during training?

The requirement for aquatic staff attire during training is essential for both functionality and safety in aquatic environments. The correct choice, which includes a guard shirt, whistle, and appropriate bathing suit, reflects the professional standards necessary for aquatic safety personnel.

A guard shirt signifies the role of the staff member and ensures they are easily identifiable to the public. Wearing a whistle is important as it allows staff to communicate effectively and signal for attention or emergencies without needing to shout, thereby maintaining order and safety in the aquatic setting. The appropriate bathing suit is crucial as it allows staff to respond quickly in the water if necessary, ensuring that they can assist patrons or rescue individuals in distress without being hampered by unsuitable attire.

The other options do not provide the necessary combination of visibility, communication tools, and readiness to engage in aquatic activities, which are essential components of effective aquatic staff training and operations.
