When is it important to use a whistle while on duty?

Using a whistle while on duty is especially important in scenarios that require immediate attention or action, such as emergencies or to signal a warning. The sound of a whistle is loud and can cut through background noise, making it an effective tool to alert individuals to a critical situation rapidly. This allows lifeguards to direct attention to the water or a specific hazard, enabling a quick response to help prevent accidents and ensure safety.

In situations that may not require an immediate response, such as during breaks or when communicating with other lifeguards, it is likely more appropriate to use verbal communication or other signals instead of a whistle. Whistles are intended for urgent circumstances where clear and immediate attention is necessary, making them an essential part of a lifeguard's emergency response toolkit. When a patron merely requests assistance, verbal communication is often sufficient and more appropriate than sounding a whistle.
