What does two short whistle blasts signify in lifeguard communication?

Two short whistle blasts are used primarily to get the attention of a lifeguard or supervisor. This signal is effective in a busy pool environment where verbal communication may be difficult due to noise or distance. By using this method, lifeguards can quickly alert one another to important situations or draw attention to an issue that may require immediate attention.

In contrast, activating the emergency action plan typically involves a more urgent and standardized protocol, often communicated through specific, longer signals or actions. Indicating a guest in distress usually requires a different form of communication, such as a continuous blast or specific gestures to clearly convey the severity of the situation. Similarly, requesting that everyone leave the pool would generally necessitate a more forceful signal, such as several short blasts or a single long blast to ensure that the message is understood by all guests promptly. Thus, the use of two short blasts serves a distinct purpose of attention-getting, vital for maintaining safety and organization in the pool area.
