Which group is primarily responsible for implementing rider screening procedures?

The group responsible for implementing rider screening procedures is primarily composed of aquatic operators and lifeguards. This is because these professionals are specifically trained in water safety protocols and are vigilant in ensuring that all riders meet the safety requirements before participating in pool or water attractions. Their training equips them with the knowledge and skills to assess each rider's suitability for the rides, including considerations related to age, height, and health conditions.

Aquatic operators and lifeguards play a critical role in maintaining the safety standards required in aquatic environments, and effectively screening riders is an essential part of their duties. They are often at the forefront of ensuring that all safety measures are observed for the protection of guests, which includes implementing and monitoring the rider screening procedures.

While other groups, like park management teams, may set policies and create guidelines regarding rider safety, it is the aquatic operators and lifeguards who directly enforce these procedures on-site to ensure guest safety.
