Why is it important for lifeguards to have first-aid supplies on hand?

The importance of lifeguards having first-aid supplies readily available is rooted in their responsibility for the safety and well-being of all individuals in and around the water. Having first-aid supplies allows lifeguards to respond effectively to injuries and emergencies that may occur at the pool or beach. This readiness to act is crucial because situations can escalate quickly, and immediate treatment can often be the difference between a minor incident and a more severe outcome.

In cases of injury, whether it be cuts, sprains, or more serious conditions like drowning or heart attacks, the timely application of first aid can stabilize a person's condition until professional medical help arrives. Lifeguards are in a unique position where they need to act swiftly; their training and access to first-aid supplies enable them to provide a critical initial response to a variety of situations, emphasizing the vital role they play in emergency management.

Other options may seem relevant at first glance, such as treating sunburns or performing routine checks, but they do not encompass the primary need of having these supplies on hand — which is to ensure the immediate and appropriate response to emergencies. Waiting for emergency services could lead to delays that may jeopardize the health and safety of individuals needing aid.
