Find a Playground Equipment Expert →Overview
A playground expert decides whether a piece of equipment, its surfacing and its upkeep met the accepted safety criteria, and whether a shortfall explains the injury. Most cases come down to a short list: how far the child fell and onto what, whether an opening could trap a head, whether the use zone was clear, and whether anyone maintained the site. This page covers public and home playground equipment. A child's medical care belongs to a pediatric physician, school supervision in general belongs to a school safety expert, and a broken part's fracture belongs to a failure analyst.
The expert reads the manufacturer's installation and maintenance instructions, purchase records, inspection logs, work orders, incident reports and site photographs, then measures the equipment and surfacing in the field. Surfacing depth changes over time, so the measurement should be taken as close to the incident as possible, and the site should be preserved before anyone rakes or tops it off.
CPSC's Public Playground Safety Handbook is the main reference, and its current edition is dated July 2025 1. CPSC believes guidelines, rather than a mandatory rule, are appropriate, and the handbook says they are not requirements or the sole method to minimize injuries 1. The voluntary standard is ASTM F1487, first published in 1993, which the handbook says is revised every 3 to 4 years 1. So neither is automatically law. They may become binding through a state statute, a licensing rule, a contract or a purchase specification, and an expert should find out which version applied when the equipment was bought or installed.
Older equipment raises its own question: was the playground obliged to meet a later edition? The answer depends on the source of the duty. An expert should separate what was compliant when installed from what a reasonable operator would have changed after learning of a known hazard.
The handbook calls falls a very common playground hazard pattern, and it calls the installation and maintenance of protective surfacing crucial to protect children from severe head injuries 1. Testing to ASTM F1292 gives a critical height rating, which can be considered an approximation of the fall height below which a life-threatening head injury would not be expected to occur 1. That wording matters on both sides. A compliant surface does not promise that no injury will happen, and the rating says nothing about a broken arm.
Fall height is measured from the highest designated playing surface to the protective surface beneath it, and the use zone should extend a minimum of 6 feet in all directions from the perimeter of the equipment 1. CPSC strongly recommends against installing playgrounds over hard surfaces such as asphalt or concrete unless protective layers are added 1. Loose-fill materials are a frequent problem, since the handbook says they can compress over time and need frequent maintenance so that depth never drops below the minimum 1.
Head entrapment has a measurable test. Certain openings could present an entrapment hazard if the distance between interior opposing surfaces is greater than 3.5 inches and less than 9 inches 1. The expert uses the handbook's test approach rather than a tape measure alone. Crush and shear points are addressed too, and the handbook lists clothing with a drawstring among the entanglement hazards 1.
Maintenance is often the deciding issue. The handbook says inadequate maintenance of playground equipment and surfacing has resulted in injuries, and that the manufacturer's maintenance instructions and inspection schedules should be strictly followed 1. Adult supervision is highly recommended 1. A missing log is not proof that no one looked, but it leaves the owner with little to show.
Home equipment falls outside the public handbook, which CPSC addresses in a separate outdoor home playground guide 2. The handbook says older playgrounds with lead-based paints should be identified 1, and federal law separately addresses lead in children's products 5.
Under the 2010 ADA Standards, play areas for children ages 2 and over must comply with section 240 3. A claim may concern the accessible route or surfacing, since a surface can meet a fall rating and still be hard for a wheelchair to cross.
Look for a Certified Playground Safety Inspector through the National Recreation and Park Association 4, with real field experience, or an engineer who has worked with these standards. Ask which edition the expert applied and what was measured on site.

Look for a Certified Playground Safety Inspector through the National Recreation and Park Association with real field experience, or an engineer who has worked with these standards. Ask which edition of the guidance the expert applied and what was measured at the site, not only what was seen in photographs.
Not by themselves. CPSC believes guidelines, rather than a mandatory rule, are appropriate. ASTM F1487 is a voluntary standard. Either one can become binding through a state law, licensing rule, contract or specification, so the expert identifies what applied to that site.
Testing under ASTM F1292 gives a surface a critical height rating. CPSC says it can be considered an approximation of the fall height below which a life-threatening head injury would not be expected to occur. It does not promise that no injury will occur, and it does not address other injuries.
The CPSC handbook says the use zone should extend a minimum of 6 feet in all directions from the perimeter of the equipment, with specific rules for certain equipment such as swings and slides. An expert should read the section for the piece at issue.
Surfacing depth and condition change quickly, and loose-fill material can be raked or topped off. Measurements taken soon after the event, with the equipment left as it was, are far stronger. Maintenance logs and work orders should be kept as well.
In general, playground equipment expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are certification, field inspection experience, site testing needs and the volume of records to review. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
