What should a lifeguard do if lightning is detected within 0-8 miles?

When lightning is detected within a distance of 0-8 miles, it poses a significant risk to individuals in outdoor swimming areas. The appropriate action for a lifeguard in this scenario is to close outdoor pools and decks. This is crucial because being outdoors during a lightning storm greatly increases the likelihood of injury or fatality due to lightning strikes.

Lightning can strike water, and individuals in or near water are particularly vulnerable due to its conductive properties. Additionally, areas like decks are also at risk since they can act as pathways for electricity. Closing outdoor facilities helps ensure that swimmers and bystanders are moved to safety, away from potential hazards associated with lightning.

Keeping indoor pools open may seem safer, but it is essential to assess whether those facilities are adequately protected from the storm's effects. Increasing swimmer supervision or conducting a safety drill does not address the immediate danger posed by lightning. Therefore, closing outdoor pools and decks is a proactive step to safeguard patrons and minimize risk during severe weather conditions.
