What immediate action should be taken in the event of an electrical system malfunction at the pool?

In the event of an electrical system malfunction at the pool, the most critical action is to clear the pool and inform all patrons. This step is crucial for safety because electrical malfunctions can pose significant risks, including potential electrocution or other injuries caused by faulty equipment. By evacuating the area, you protect patrons from possible harm and allow staff to assess the situation without the added complexity of managing crowd control.

Informing patrons ensures they are aware of the potential danger and helps to maintain order during an emergency situation. The priority is always to ensure the safety of everyone present at the facility, and taking immediate action to clear the pool is the first line of defense in addressing a serious incident like an electrical failure.
