CPSI Playground Equipment Installation Requirements — Questions and Answers
Question 1: What is the primary reason playground equipment footings must extend below the local frost line?
- To keep anchor bolts hidden from sight for aesthetic reasons
- To prevent frost heave from destabilizing equipment and creating tripping or structural hazards (Correct answer)
- To comply with CPSC requirements for footing depth regardless of climate
- To ensure the equipment cannot be removed or vandalized
Correct answer: To prevent frost heave from destabilizing equipment and creating tripping or structural hazards
Frost heave occurs when water in the soil freezes and expands, pushing footings upward. If footings do not extend below the frost line, equipment can shift, tilt, or create ground-level trip hazards and structural instability — all of which are safety-critical findings for a CPSI inspector.
Question 2: During a post-installation inspection, a CPSI inspector discovers that several anchor bolt heads protrude 0.75 inches above the ground surface around the equipment base. What action is required?
- No action — protruding anchor bolts are standard and expected after installation
- Document the finding for the next scheduled inspection
- Require that bolts be recessed or fitted with protective covers to eliminate the protrusion hazard (Correct answer)
- Paint the bolt heads a bright color to increase visibility
Correct answer: Require that bolts be recessed or fitted with protective covers to eliminate the protrusion hazard
Exposed, protruding hardware is a protrusion hazard that can impale or injure children. ASTM F1487 and CPSC guidelines require that hardware be recessed, covered with protective caps, or otherwise rendered non-hazardous. Painting does not eliminate the physical hazard.
Question 3: After installation, an inspector finds that the use zones of two adjacent climbing structures overlap by 3 feet. What is the correct course of action?
- Accept the installation if the surfacing depth is increased in the overlap area
- Recommend relocating or reconfiguring at least one structure to eliminate the use zone overlap (Correct answer)
- Place a physical barrier in the overlap area to separate users
- Document the overlap but allow use, since both zones are surfaced
Correct answer: Recommend relocating or reconfiguring at least one structure to eliminate the use zone overlap
Overlapping use zones create a condition where a child falling from one structure can land in the path of a child using or falling from the adjacent structure. The correct remedy is physical separation — relocating or reconfiguring equipment — not surfacing adjustments or barriers within the fall zone.
Question 4: Which document must the manufacturer provide at the time of equipment delivery that a CPSI inspector would reference during a post-installation inspection?
- The marketing brochure and retail price list
- The purchase order and shipping invoice
- The manufacturer's installation instructions and ASTM compliance documentation (Correct answer)
- The local building department approval letter only
Correct answer: The manufacturer's installation instructions and ASTM compliance documentation
Manufacturer-supplied installation instructions define proper assembly, torque specifications, anchoring depth, and hardware requirements. ASTM compliance documentation confirms the equipment was designed to meet applicable standards. A CPSI inspector uses these documents to verify the equipment was installed correctly.
Question 5: A CPSI inspector is verifying hardware on newly installed equipment. Which combination of findings would require immediate corrective action before the equipment is opened to the public?
- Hardware is stainless steel; all bolts are flush with the surface
- One bolt is under-torqued and loose; a connecting bracket has a sharp edge measuring 0.04 inches radius (Correct answer)
- Plastic protective caps are present on all exposed bolt ends
- All hardware is galvanized; torque values match manufacturer specifications
Correct answer: One bolt is under-torqued and loose; a connecting bracket has a sharp edge measuring 0.04 inches radius
A loose bolt compromises structural integrity and represents an immediate hazard. A sharp edge with a radius under 0.04 inches (approximately 1 mm) meets the ASTM definition of a sharp-edge hazard. Both findings individually require correction before public use; together they make the equipment unsafe for opening.
Question 6: During a post-installation inspection, what is the purpose of verifying that the equipment's critical fall height matches the installed surfacing's rated attenuation depth?
- To confirm the equipment color scheme is appropriate for the age group
- To ensure the surfacing will absorb sufficient impact energy if a child falls from the highest accessible point (Correct answer)
- To calculate the maximum number of children who can use the equipment simultaneously
- To document the equipment's warranty terms for insurance purposes
Correct answer: To ensure the surfacing will absorb sufficient impact energy if a child falls from the highest accessible point
Critical fall height is the highest accessible point on the equipment from which a child could fall. The installed surfacing must be rated (via ASTM F1292 testing) to attenuate a fall from that height to a Gmax ≤ 200 and HIC ≤ 1000. Mismatches between fall height and surfacing depth ratings mean the surfacing will not adequately protect a falling child.
