Which of the following actions detracts from a lifeguard's professional image?

Leaning on a post and not wearing a uniform is an action that detracts from a lifeguard's professional image because it conveys a lack of attentiveness and seriousness regarding the responsibilities of the position. A lifeguard's professional appearance is crucial in establishing a sense of authority, trust, and alertness among patrons. When a lifeguard is not in uniform, it can confuse guests about who is responsible for their safety and undermine the lifeguard's credibility.

Being attentive and focused, engaging positively with guests, and using appropriate hand signals are all actions that enhance a lifeguard's professional image. These behaviors demonstrate vigilance, readiness to assist, and effective communication, all of which are essential components of a lifeguard's role in ensuring a safe environment. Proper uniform attire further reinforces the lifeguard's status and professionalism, making it clear to the public who is in charge of their safety.
