6.1 Miscellaneous Hazards

6.1 Miscellaneous Hazards

Domain 1N of the National Recreation and Park Association (NRPA) Certified Playground Safety Inspector (CPSI) blueprint is the leftover basket. Domains 1F through 1M already taught entanglement, protrusion, entrapment, and crush/shear. What remains still injures children: a raw tube end that splits a lip, a slack cable at chest height in a run path, a concrete footing proud of the mulch, a steel belt wicking out of a recycled tire, and a shade-sail beam or tree limb in the head path of a swing. The U.S. Consumer Product Safety Commission (CPSC) Public Playground Safety Handbook, Publication 325 (July 2025), gathers those families in §§3.4–3.8. American Society for Testing and Materials (ASTM) F1487-21 and the NRPA Table of Dimensions (Rev 1/2024) — the sheet handed to you in the exam room — give the field numbers.

Sharp points, corners, and edges (CPSC 2025 §3.4)

Sharp points, corners, or edges on any part of the playground or the equipment may cut or puncture a child’s skin. Sharp edges produce serious lacerations when a child slides, falls, or braces a hand. §3.4 is a finish-and-hardware control, not a protrusion-gauge test. You still run the projection gauges from Domain 1I when a bolt stands proud; you also walk the same site for raw metal, splinters, and open tubes.

CPSC lists the protective measures in inspection language:

• Open tubing. Exposed open ends of all tubing that are not resting on the ground or otherwise covered must be closed by caps or plugs that cannot be removed without tools. A press-fit plastic plug a child can pull with fingers fails the section even if the tube is not a protrusion. The July 2025 edition adds one explicit relief: chimes, tubes, or other musical equipment may have exposed open ends if the ends are rounded.
• Wood. Wood parts must be smooth and free from splinters. Check end grain, worn slide sidewalls, and the top arris of a timber border.
• Corners. All corners, metal and wood, should be rounded.
• Metal edges. All metal edges should be rolled or have rounded capping. Pay special attention to slide side rails and the exit lip (CPSC also points you to §5.3.6.4). There should be no sharp edges on slides.
• Steel-belted radials. If they are used as equipment, examine them regularly so no steel belts or wires are exposed. The same belt check returns in §3.7.
• Wear. Frequent inspection is how you catch splinters, rolled edges that have flattened, and caps that have cracked off.

A missing end cap that is not a protrusion and not a clothing-catch is still a §3.4 finding. Rank it as maintenance unless the open tube is also a projection or a drawstring catch — then you write both findings and rank the life-safety mechanism.

Suspended hazards (CPSC 2025 §3.5)

Children are injured when they run into or trip over suspended components — cables, wires, ropes, or other flexible parts — that connect one structure to another or hang to the ground. Those members become the §3.5 hazard when they are within 45 degrees of horizontal and less than 7 feet (84 inches) above the protective surfacing. The 2025 sentence is explicit about the injury: a tripping or upper-body impact hazard. This is not the same finding as a one-ended rope that can wrap a neck (Domain 1F). One slack line can be both; write both if both tests fail.

To avoid a suspended hazard, CPSC requires four controls:

1. Locate the member away from high-traffic areas — not across the path from the swing bay to the slide exit.
2. Make it highly visible: brightly colored, contrasting with equipment and surfacing, or given other features that increase visibility.
3. It must not be able to be looped back on itself or onto another rope, cable, or chain to create a circle with a 5 inch or greater perimeter. The NRPA Table states the companion loop rule as a minimum inside perimeter of 5 inches for a suspended loop; a small closed loop is a noose, and a long unsecured tail is how a child makes a 5-inch-plus circle.
4. It must be fastened at both ends unless it is 7 inches or less long or is attached to a swing seat. The Table repeats the one-ended maximum: 7 inches.

Exceptions in CPSC 2025 §3.5. The four recommendations do not apply to swings, climbing nets, a component more than 7 feet above the protective surfacing, or a component that is a minimum of 1 inch at its widest cross-section. The user-facing 2025 conjunction is or. When the exam stem cites the NRPA Table of Dimensions or F1487, use the Table’s dual rule for a non-rigid member suspended between play units: minimum height 84 inches and minimum diameter 1 inch. Do not treat a skinny, low slack rope as exempt just because someone painted it yellow.

Tripping hazards (CPSC 2025 §3.6)

Play areas should be free of sudden elevation changes that trip a running child. CPSC names two classic causes: anchoring devices and containment walls for loose-fill.

All anchoring devices — concrete footings, the horizontal bar at the bottom of a flexible climber, deadmen, and similar hardware — must be installed below ground level and beneath the base of the protective surfacing. Burial does two jobs: it removes the trip lip, and it keeps a falling child from taking a second impact on exposed concrete. A footing that has heaved, washed out, or been left proud after a surface top-up is a current §3.6 finding even if the original installation was correct.

Visibility is the rest of the section:

• Contrast the surfacing color with the equipment color.
• Surfacing containment walls should be highly visible.
• Any change of elevation should be obvious.
• Contrast the containment barrier with the surfacing so a child can see the lip.

A timber border flush with compacted fill that later settles into a 3-inch cliff is the field version of “the change of elevation is no longer obvious.”

Used tires (CPSC 2025 §3.7)

Used automobile and truck tires show up as tire swings, flexible climbers, cushioning under a seesaw, or shredded surfacing. When tires are used:

• Inspect steel-belted radials so no belts or wires are exposed. A wicking belt is a laceration and a tetanus conversation; it is also a sharp-edge finding under §3.4.
• Provide drainage holes on the underside so the tire does not collect water and debris (mosquitoes, bees, hidden glass).
• The 2025 handbook tells owners to consider plastic playground equipment that simulates tires instead of reusing automobile tires. Recycled tire rubber mulch is a different product family (ASTM F3012 plus F1292) and is not a substitute for inspecting a whole tire used as a climber.

Overhead obstructions (CPSC 2025 §3.8 and F1487)

Section 3.8 is short and new as a standalone heading in the 2025 book: install equipment away from tree limbs, shading structures, or anything else overhead that could produce an impact, fall, or entanglement hazard. CPSC then sends you to ASTM F1487 for the numbers. The NRPA Table and standard F1487 teaching you must carry are:

• 84 inches of overhead clearance above a designated play surface, measured in the space outside or above the use zone.
• For swings, overhead (roof-line) clearance from the pivot to the obstruction is X + 42 inches, where X is the distance from the pivot to the protective surfacing.

A shade-sail beam 72 inches above a 48-inch deck is not “nice shade.” It is an F1487 overhead obstruction. A limb in the to-fro arc that sits closer than X + 42 inches to the pivot is the same finding with a different tape measurement.

Walk Domain 1N in that order so you do not let a pretty shade structure or a “just a cable” excuse bury a finding the Table already quantified.
