Detect and penalize any infractions, such as false starts or improper strokes.

Intervene if any unsafe situations arise.

Accuracy and Efficiency:

Accurately record times and results.
Oversee the smooth flow of events to keep the competition on schedule.

Providing Guidance and Support:

Assist swimmers, coaches, and other officials in understanding the rules and addressing any concerns.
Promote a positive atmosphere for participants and spectators.

Officials play a crucial role in upholding the integrity and professionalism of the competition.
