What essential equipment should a WSI have on hand during lessons?

Having life jackets, rescue tubes, and a first aid kit on hand during lessons is crucial for a Water Safety Instructor because these items ensure the safety and well-being of all participants. Life jackets provide buoyancy and help prevent drowning, especially for beginners or individuals who may not be strong swimmers. Rescue tubes are essential for conducting rescues in water emergencies, allowing instructors to safely reach individuals in distress. A well-stocked first aid kit is vital for addressing any injuries or health issues that may arise during lessons, ensuring that a quick response is possible.

While the other options include equipment that may enhance the learning experience or contribute to comfort, they do not address the safety requirements as directly as the correct answer. Swim caps and goggles can aid in visibility and hair management, kickboards and floats assist in teaching various swimming techniques, and drying towels and sunscreen improve comfort after swimming activities. However, none of these options replace the critical safety gear that is necessary to effectively manage aquatic risks.
