CPO Safety Protocols & Emergency Response 2 — Questions and Answers
Question 1: What is the minimum recommended ratio of lifeguards to swimmers in a public pool according to standard safety guidelines?
- 1 lifeguard per 10 swimmers
- 1 lifeguard per 25 swimmers
- 1 lifeguard per 50 swimmers (Correct answer)
- 1 lifeguard per 100 swimmers
Correct 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.
Question 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?
- 15 minutes
- 30 minutes (Correct answer)
- 25 minutes
- 1 hour
Correct 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.
Question 3: Which type of rescue equipment should ALWAYS be immediately accessible at poolside for a lifeguard?
- SCUBA gear
- Reaching pole and ring buoy (Correct answer)
- Underwater camera
- Pool noodle
Correct 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.
Question 4: In the event of a lightning storm, when should an outdoor pool be closed and patrons evacuated?
- Only when lightning strikes within 1 mile
- When thunder is heard or lightning is seen, regardless of distance (Correct answer)
- When the National Weather Service issues an official warning
- Only when lightning strikes within 5 miles
Correct 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.
Question 5: What action should a pool operator take if a patron reports that a drain cover is broken or missing?
- Post a warning sign and continue operations
- Rope off only the immediate area around the drain
- Immediately close the pool until the cover is repaired or replaced (Correct answer)
- Reduce pump speed to lower suction
Correct 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.
Question 6: What is the purpose of a 'secondary' or 'backup' drowning prevention system in an aquatic facility?
- To replace lifeguards during breaks
- To provide an additional layer of protection supplementing lifeguard supervision (Correct answer)
- To monitor water chemistry automatically
- To control pool lighting for visibility
Correct 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.
Question 7: Which document should detail the exact procedures for every type of emergency that may occur at an aquatic facility?
- The pool chemical log
- The Emergency Action Plan (EAP) (Correct answer)
- The daily inspection checklist
- The aquatic facility permit
Correct 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.
