Which of the following could cause blind spots in a pool area?

The phenomenon of blind spots in a pool area can arise from various factors, one of which is the equipment, pool edge, or overall design of the facility. For instance, large structures such as diving boards, slides, or even the shape of the pool itself can obstruct the lifeguard's line of sight, limiting visibility in certain areas. Additionally, the placement of furniture or other poolside equipment can also create areas where lifeguards cannot easily monitor.

Although other factors such as poor lighting conditions and large crowds do contribute to visibility issues, equipment and design specifically pertain to the physical layout and obstructions present in the environment. In contrast to these factors, poor lighting can create an overall dimness that affects visibility throughout the pool, while large crowds can lead to a general reduction in the ability to see through a mass of people, but do not create structural blind spots. Therefore, the role of the pool's design and equipment is crucial in understanding how blind spots can specifically be created.
