  1. What is the minimum recommended ratio of lifeguards to swimmers in a public pool according to standard safety guidelines?

    Answer: 1 lifeguard per 50 swimmers

    Standard guidelines typically recommend a minimum of 1 lifeguard per 50 swimmers, though local regulations may require stricter ratios.

  2. When performing an emergency pool closure due to a fecal incident involving formed stool, what is the minimum hyperchlorination contact time at 2 mg/L free chlorine?

    Answer: 30 minutes

    A formed fecal incident requires raising free chlorine to 2 mg/L and maintaining it for at least 30 minutes before reopening.

  3. Which type of rescue equipment should ALWAYS be immediately accessible at poolside for a lifeguard?

    Answer: Reaching pole and ring buoy

    A reaching pole and ring buoy (or similar throwing device) must always be immediately accessible at poolside for non-contact rescues.

  4. In the event of a lightning storm, when should an outdoor pool be closed and patrons evacuated?

    Answer: When thunder is heard or lightning is seen, regardless of distance

    The standard rule is to clear the pool immediately upon hearing thunder or seeing lightning, as lightning can strike miles from a storm.

  5. What action should a pool operator take if a patron reports that a drain cover is broken or missing?

    Answer: Immediately close the pool until the cover is repaired or replaced

    A missing or broken drain cover creates a life-threatening entrapment hazard and requires immediate pool closure until it is repaired.

  6. What is the purpose of a 'secondary' or 'backup' drowning prevention system in an aquatic facility?

    Answer: To provide an additional layer of protection supplementing lifeguard supervision

    Secondary drowning prevention systems such as underwater alarms or cameras supplement—but never replace—lifeguard supervision.

  7. Which document should detail the exact procedures for every type of emergency that may occur at an aquatic facility?

    Answer: The Emergency Action Plan (EAP)

    The Emergency Action Plan (EAP) outlines specific procedures for all foreseeable emergencies and must be known by all staff.
