Which of the following is NOT a benefit of using a high chair?

The key to understanding why the proximity to patrons for help is not a benefit of using a high chair lies in the design and purpose of high chairs in the lifeguard context. High chairs are elevated platforms that allow lifeguards to have a better vantage point over the pool area, ensuring they can monitor swimmers effectively. However, this height can actually increase the distance between the lifeguard and the patrons, making it more challenging to respond quickly to someone in need of immediate assistance.

In contrast, the other options highlight genuine benefits of using a high chair. For example, a high chair reduces glare and reflection from the water, enhancing visibility for the lifeguard. Being elevated also allows for an improved view of the pool's bottom, providing better oversight for spotting any potential hazards or issues. Furthermore, increased distance from noise can help lifeguards focus on monitoring the pool without being distracted by ambient sounds.

Therefore, while high chairs offer several advantages in terms of visibility and safety, they do not facilitate close proximity to patrons, which is crucial for timely assistance in emergency situations.
