What should lifeguards do when they need assistance?

When lifeguards need assistance, raising a fist is a widely recognized and effective signal that indicates help is required. This gesture is clear and can be seen from a distance, allowing other lifeguards or team members to quickly understand that immediate assistance is necessary. The raised fist serves as both a visual and standardized signal in many lifeguarding protocols, ensuring that help can be mobilized without confusion.

Using a whistle, while it may draw attention, is typically utilized for alerting patrons or signaling to other lifeguards in non-emergency situations rather than directly indicating the need for assistance. Waving to guests may create unnecessary confusion and may not effectively communicate the urgency of the situation. Calling out loudly can result in the lifeguard's voice being drowned out by noise from guests or the environment, making it less reliable than the clear and precise action of raising a fist.
