The most critical action a lifeguard should take while on surveillance duty during a busy swim session is to wear a hip pack and carry a rescue tube. This is essential because the rescue tube is a primary flotation device that lifeguards use to assist distressed swimmers quickly and effectively. Being equipped with the rescue tube allows the lifeguard to respond to emergencies promptly, enabling immediate intervention and increasing the chances of a successful rescue.

Wearing the hip pack is also important as it typically contains essential equipment, such as a whistle and potentially a radio for communication. This preparation is vital for maintaining a high level of surveillance and readiness, particularly during busy periods when the risk of incidents increases due to the number of swimmers. Swift action in emergencies can save lives, making the readiness for immediate response the top priority for safety during any swim session.
