CPI Safety Regulations & Compliance 2 — Questions and Answers
Question 1: Under the Virginia Graeme Baker Pool and Spa Safety Act, what is required for public pool drains to prevent entrapment?
- Single unblockable drain
- ASME/ANSI A112.19.8 compliant drain covers (Correct answer)
- Drain covers replaced every 5 years regardless of condition
- Drains must be covered with metal grates only
Correct answer: ASME/ANSI A112.19.8 compliant drain covers
The VGB Act requires drain covers to meet ASME/ANSI A112.19.8 standards to prevent suction entrapment hazards.
Question 2: What minimum water depth is typically required before a diving board can be installed at a residential pool per ANSI/NSPI standards?
- 6 feet
- 7 feet
- 8 feet (Correct answer)
- 5 feet
Correct answer: 8 feet
ANSI/NSPI standards generally require a minimum pool depth of 8 feet in the diving zone for residential diving board installations.
Question 3: Which chemical is classified as an oxidizer and must be stored separately from chlorine products in a pool chemical storage area?
- Muriatic acid
- Cyanuric acid
- Calcium hypochlorite (Correct answer)
- Sodium bicarbonate
Correct answer: Calcium hypochlorite
Calcium hypochlorite is a strong oxidizer that can react violently with other pool chemicals, including acids, and must be stored separately.
Question 4: According to OSHA guidelines for aquatic facilities, what is the recommended maximum noise level for extended worker exposure in a natatorium?
- 70 dBA
- 85 dBA
- 90 dBA (Correct answer)
- 95 dBA
Correct answer: 90 dBA
OSHA's permissible noise exposure limit for an 8-hour workday is 90 dBA, which applies to natatorium environments.
Question 5: A CPI inspector finds that a public pool's emergency shutoff for the recirculation system is located inside the pump room. What is the compliance issue?
- No issue — inside the pump room is the correct location
- Emergency shutoffs must be located outside the pump room for safe access during an emergency (Correct answer)
- Emergency shutoffs are only required for spas, not pools
- The shutoff must be color-coded red but location is acceptable
Correct answer: Emergency shutoffs must be located outside the pump room for safe access during an emergency
Emergency shutoffs must be accessible from outside the pump room so personnel can safely shut down the system without entering a potentially hazardous area.
Question 6: Under the Model Aquatic Health Code (MAHC), what is the required minimum free available chlorine level for a traditional outdoor public pool?
- 0.5 ppm
- 1.0 ppm (Correct answer)
- 2.0 ppm
- 3.0 ppm
Correct answer: 1.0 ppm
The MAHC recommends a minimum free available chlorine level of 1.0 ppm for traditional outdoor public pools.
Question 7: When inspecting a pool ladder, a CPI finds the handrails are 24 inches apart. What is the compliance issue?
- No issue — 24 inches is within the acceptable range
- Handrails must be no more than 18 inches apart to prevent entrapment (Correct answer)
- Handrails must be at least 17 inches but no more than 24 inches apart
- Handrails spacing is not regulated by safety codes
Correct answer: Handrails must be no more than 18 inches apart to prevent entrapment
Most codes require pool ladder handrails to be no more than 18 inches apart to prevent a child's body from passing through and becoming entrapped.
