Which of the following is a potential premises hazard?

Glare and reflection is identified as a potential premises hazard because it can significantly impair visibility for both lifeguards and swimmers. When the sun produces glare on the water's surface or when reflections bounce off surfaces, it can create blind spots and limit a lifeguard's ability to spot distressed swimmers or hazards. This issue can lead to delayed response times in emergencies, which increases the risk of incidents happening in the pool or aquatic environment.

Understanding how glare affects visibility helps lifeguards anticipate and manage risks more effectively. While supervision of swimmers, personal flotation devices, and aquatic fitness classes are all important elements of water safety, they are not categorized as premises hazards. Instead, they pertain to safety protocols and activities designed to enhance swimmer protection and enjoyment.
