A drowning occurs usually when the swimmer quietly slips beneath the surface. Thus, there is no clue to other persons in the area of a problem. Typically, due to water ingestion, the inability to surface, or simply fatigue, the swimmer is not seen nor heard. Unless somebody is actively watching the pool, the drowning victim goes unnoticed. If kids are in or near the pool, at least one responsible adult who is able to render aid must be on duty watching the pool. This person cannot be engaged in conversation, consuming alcohol or participating in social activity that could cause a distraction. It's best to have two parents on duty, on opposite sides of the pool. Keep order around the pool deck. Keep large objects that can obstruct your view of the bottom of the pool out of the water. Keep your eyes on the water at all times!
