Which of the following is considered a physical hazard near pools?

Wet surfaces are considered a physical hazard near pools because they can lead to slips and falls. When pool areas are wet, whether from splashing water, spilled beverages, or rain, they create a slippery environment that poses a significant risk to both swimmers and spectators. Ensuring that pathways, decks, and surrounding areas are properly maintained and dry is crucial for preventing injuries.

In contrast, while inadequate life-saving equipment, swimming without supervision, and insufficient pool signage are important safety concerns, they fall more into the categories of equipment safety, supervision, and informational hazards rather than strictly physical hazards associated directly with the physical environment. Thus, wet surfaces are directly linked to the physical conditions that can cause accidents around pools.
