How common are playground injuries?

CPSC’s Public Playground Safety Handbook gives the headline figure in §1.7: “over 200,000 estimated emergency room-treated injuries annually”. The word that matters there is estimated — it is a national estimate, not a count. §1.7 attaches no years to it at all, so the only safe thing to say about when it was current is that the 2010 edition of the handbook printed it without a period, and a reader should take it as of that edition.

The Commission published a later analysis of the same kind in August 2016, and that one states its period on the page: an estimated 1,459,201 emergency department-treated injuries associated with playground equipment over the six years 2009 to 2014. Across those six years that is an estimated annual average of 243,200; across 2012 to 2014, the most recent three years of the period it examined, 247,075. The 2016 report prints a 95 percent confidence interval for the six-year total of 1,201,226 to 1,717,176, and says that “No statistically significant trend exists over the 2009 to 2014 period.”

Both are national estimates of injuries treated in emergency rooms, not counts of anything, and neither is a figure for one playground or one kind of playground. We found no CPSC analysis of this kind covering any period after 2014, so the newest figure on this page describes 2009 to 2014 and everything below it is older. Where a number comes from a study, the study’s years are given with it.

The handbook says it twice, and not the same way

Pub. 325 states the figure in two places and the two sentences do not claim the same thing. Chapter 1 opens with this, in bold on printed page 1: “In recent years, it is estimated that there were more than 200,000 injuries annually on public playgrounds across the country that required emergency room treatment.” (CPSC, Pub. 325, §1.) §1.7, on printed page 3, opens with this: “The U. S. Consumer Product Safety Commission has long recognized the potential hazards that exist with the use of playground equipment, with over 200,000 estimated emergency room-treated injuries annually.”

One says the injuries happened “on public playgrounds”; the other says only that they are associated with “the use of playground equipment” and does not say where. They are printed two pages apart and neither gives the years it is counting. That is why this page quotes them separately rather than merging them into one sentence, and it is worth knowing which of the two anybody else is quoting at you.

The 2016 report does say where, and its own estimate is not confined to public playgrounds: of the 1,459,201, “An estimated 885,928 injuries (61 percent) occurred at schools or parks, an additional 203,551 injuries (14 percent) were in home locations.” By age: “An estimated 740,618 injuries (51 percent) occurred in the 5 to 9 years of age category, an additional 380,342 injuries (26 percent) were under 5 years of age.” By diagnosis: 492,001 fractures (34 percent), then 251,699 contusions or abrasions (17 percent), 216,421 lacerations (15 percent) and 184,999 strains or sprains (13 percent).

What causes them

This is where the widely repeated numbers come from, and where they are most often repeated wrongly. §1.7 in full on the point:

“The most recent study of 2,691 playground equipment-related incidents reported to the CPSC from 2001-2008 indicated that falls are the most common hazard pattern (44% of injuries) followed by equipment-related hazards, such as breakage, tip over, design, and assembly (23%). Other hazard patterns involved entrapment and colliding other children or stationary equipment.” (CPSC, Pub. 325, §1.7.)

Three things about that sentence, because it is quoted loosely everywhere:

• 2,691 is a count of incidents reported to the CPSC, across the eight years 2001 to 2008 together. It is not a number of injuries, it is not an annual figure, and it is not a national estimate. It is the reports that reached the Commission.
• The 44% and the 23% are shares of those 2,691 reports, not shares of all playground injuries and not shares of the 200,000-a-year estimate. Two different data sets sit in the same paragraph.
• The study is dated. §1.7 footnotes it as O’Brien, Craig W., Injuries and Investigated Deaths Associated with Playground Equipment, 2001-2008, U.S. Consumer Product Safety Commission, October 2009. Anything drawn from it describes 2001 to 2008.

The Commission’s 2016 report is the direct successor to that study, and its split for 2009 to 2014 comes out close to the reverse of the 2001 to 2008 one. It records 3,014 incidents reported to CPSC staff for all ages, and from that raw total equipment-related hazards work out at 1,907 (63 percent) against 523 falls (17 percent) — but 1,239 of those 3,014 are one manufacturer’s own reports of a single brand of seesaw seat breaking, a product recalled in 2012, so the 63 percent is mostly a count of one recall rather than a picture of playgrounds.

That is the report’s own account of itself, on its printed page 9: “There were 1,239 incidents involving a specific brand of seesaw seats breaking, which posed a fall hazard and that were reported by a manufacturer. The distribution of hazard pattern and equipment type overall was skewed toward equipment-related and seesaw/teeter totters ... The product was recalled in 2012.” It prints the same table again with those reports removed: 1,775 incidents, equipment-related 668 (38 percent), falls 523 (29 percent). Those are the shares to use, and the recall is the thing to say in the same breath as the 63 whenever anybody quotes that number at you.

Even at 38 to 29 the two studies still disagree about which category is largest, and neither report explains the remainder. The 2016 report’s own position is that the comparison should not be made at all: “While the incidents reported to CPSC and the emergency department-treated injuries are similar in scope and character, staff cautions against making comparisons between the two sets of data. As described in the Appendix, the incidents reported to CPSC constitute an anecdotal data set, which may not be representative of the incidents that actually occurred.” (CPSC, Injuries and Investigated Deaths Associated with Playground Equipment 2009-2014, printed page 17.) Anecdotal is the report’s word, not ours, and it applies to the 2,691 reports in §1.7 for exactly the same reason.

Its Summary of Findings says whose playgrounds those reports are about, and for a reader of this site it is the most important sentence in the document: “92% of the incidents reported to CPSC staff occurred at home or restaurant locations, while 60% of emergency department treated injuries occurred at places of recreation or schools.” Reports reach the Commission mostly from homes. So a hazard split calculated from reported incidents — the 44 percent in §1.7 included — is not a sample of injuries on public playgrounds, and nothing on this page should be read as saying what share of injuries at a park, a school or an apartment complex is caused by anything.

What survives all that is narrow and worth having anyway: across both studies, falls and equipment-related hazards are the two largest categories of what gets reported. The 2016 report puts the two together at “81 percent of the reported incidents” for 2009 to 2014, which is a figure that counts the recalled seesaw seats; set those aside and the same two are 67 percent of what is left. What the handbook means by each is set out elsewhere — the categories Chapter 3 defines are on common playground hazards, and the surfacing a fall lands on is on how deep playground mulch should be.

What the deaths involved

The last sentence of §1.7’s opening paragraph: “Playground-related deaths reported to the Commission involved entanglement of ropes, leashes, or clothing; falls; and impact from equipment tip over or structural failure.” The handbook gives that list no number and no years. The footnote in this section sits after the “(23%)” parenthetical, so the 2001 to 2008 dates belong to the study sentence above it and not to this one; anyone who tells you the handbook dates its list of deaths is reading a period into it.

The 2016 report does give numbers, for its own stated period: “From 2009 to 2014, CPSC staff investigated 34 deaths associated with playground equipment. Victim age ranged from 13 months to 52 years. The average age was 7 years, and the median age was 5 years.” Of those 34, 19 “were the result of hangings or other asphyxiations” — 12 of them involving a second product, 5 associated with slides, 5 on swings — and 8 “were the result of head or neck impact injuries”. These are deaths investigated by CPSC staff, not a national total.

The handbook’s list names entanglement first, but it does not say the list is ordered by frequency, and no reading of it should assume so. The 2016 report is the one that counts: of the 34 deaths it investigated, the largest named group was hangings or other asphyxiations. That is a different picture from the reported-incident figures above, where falls and equipment-related hazards lead, and the two should not be read as one ranking. The handbook’s own treatment of ropes, cords and drawstrings is in Chapter 3 and is summarised on the hazards page.

What the numbers mean for a routine round

Less than people usually say. Neither report claims that any particular check prevents any particular injury, and we are not going to claim it for them. What §1.7 does do, in its second paragraph, is say what CPSC built its recommendations out of — and that is the honest bridge between the figures above and a walk round a playground:

“The recommendations in this handbook have been developed to address the hazards that resulted in playground-related injuries and deaths. The recommendations include those that address:” (CPSC, Pub. 325, §1.7.)

• The potential for falls from and impact with equipment
• The need for impact attenuating protective surfacing under and around equipment
• Openings with the potential for head entrapment
• The scale of equipment and other design features related to user age and layout of equipment on a playground
• Installation and maintenance procedures
• General hazards presented by protrusions, sharp edges, and crush or shear points

That is the handbook’s own six-line answer to “what do the injury figures have to do with me?”, and every one of the six is a recommendation. Pub. 325 says in §1.1 that it presents its information “in the form of guidelines” and that CPSC staff believes “guidelines, rather than a mandatory rule, are appropriate”. Nothing in it requires an inspection of anyone; which documents actually bind a playground owner is a separate question, answered on what the playground safety standards are.

Two of the six are things a person can measure on a round rather than decide at purchase: the depth and condition of the protective surfacing, covered in how deep playground mulch should be, and the clear area around equipment, covered in what a playground fall zone is. The other four are mostly about how the equipment was chosen, how it was installed, and whether it has been kept in repair.

Keeping your own incident record

The handbook asks you to keep a record of injuries on your own playground, in §4.4, and it gives one reason for it: “A record of any accident and injury reported to have occurred on the playground should also be retained. This will help identify potential hazards or dangerous design features that should be corrected.” (CPSC, Pub. 325, §4.4.)

That sentence is the whole of what §4.4 claims for such a record, and this page is not going to add anything to it. It is a should, like every other instruction in §4.4.

Nothing we have read sets a retention period for an injury record. Pub. 325 sets none, for this record or any other. The two state licensing rules we have read at the primary source do set periods, but both of them govern the inspection paperwork rather than the incident report: Texas requires a licensed child care center to keep “maintenance inspections and repair records” for at least the previous three months, and North Carolina requires the Division’s playground inspection checklist to be “maintained for 12 months in the center’s files”. Neither says anything about how long an accident or injury report should be kept. Both are quoted in full, with their sources, on what a playground maintenance record should include, alongside the rest of what §4.4 asks you to keep — and if you need to know what your own state requires of an incident record, neither this page nor that one can tell you.

The practical shape of it is one line per event, filed with the inspection sheets rather than somewhere else: the date, the playground, what was reported to have happened, on or near which piece of equipment, and what was done about the equipment afterwards. §4.2 covers that last part for anything an inspection turns up — “Any problems found during the inspection should be noted and fixed as soon as possible” — and an injury report that names a piece of equipment is the same kind of prompt to go and look at it.

Walking the round

Our free playground inspection checklist is 25 pass/fail items you can print, walk and file, built from the handbook’s own Appendix A: surfacing, drainage, general hazards, hardware, durability, paint and upkeep, and then an eighth section of measurements that is ours rather than Appendix A’s. Appendix A itself is 24 boxes in seven groups, so the two do not line up item for item. It costs nothing and it needs no account.

InspectPlay is the same round as 25 pass/fail items on a phone, at $99 per playground per year. It works offline, so answers queue on the phone and sync when signal returns. Failing an item asks for a priority and an observation, then files a finding carrying the handbook’s own remedial action and section citation, and that finding stays open across rounds until someone closes it with a repair note. The report is a hosted page — the full checklist with the passes included, the measurements, the findings ranked Priority 1 to 5 and the sign-off — emailed as a link. There is no PDF file and the only export is JSON, so if your record has to sit at the site on paper, print the page.
