Bounce house safety rules: what ASTM F2374 asks of operators, and who points to it

Ohio will not permit a ride that cannot show it meets ASTM F2374, and a backyard unit from a big-box store is not built to it at all. Bounce house safety rules come from four overlapping places: the manufacturer's manual, the ASTM standard, the state or city, and your insurer. F2374 is the one the others point to.

It is also a paid document. We worked from ASTM's own scope text, the two readable places that quote its clauses (a fire department sheet and a journal paper), and the state, fire code and insurer pages that refer to it, all read on October 1, 2026. Where a source only describes the standard, we say so.

F2374 covers commercial units and leaves out consumer ones

ASTM's store page for the current edition, F2374-24, says the practice sets criteria for the "Design, Manufacture, Installation, Operation, Maintenance, Inspection, Training, Auditing and Major Modification" of commercial inflatable devices. It lists "rental companies" among the places they are used, beside schools, fairs, gyms and municipal parks, and it covers dry, wet and combination units.

It leaves out devices "marketed directly to consumers for private home use by children," which fall under a separate standard. A backyard unit from a big-box store is therefore not built to F2374, and CPSC's bulletin gives residential and commercial units separate guidance.

Editions differ by place. New Jersey's code lists F 2374-10, Maryland's current rules name F2374-22 (the older PDF still posted names the 2004 edition), North Royalton's fire sheet reproduces F2374-22 and the journal paper quotes the 2021 edition. When a rule says "F2374," ask which year it means.

F2374 asks for every tie-down, a marked wind limit and a trained attendant

The North Royalton, Ohio fire department sheet reproduces parts of F2374-22. The 2022 paper in the American Meteorological Society's Bulletin quotes others. Between them:

• Outdoors, "ALL tie downs shall be utilized, NO EXCEPTIONS". No more than one rope per stake. Where weights replace stakes, each tie-down on a bounce-type unit takes at least 75 pounds, unless the maker says more, and slides over 36 feet take about 450. No cinder blocks. No tying to a vehicle, trailer or trash bin.
• The design must assume operation at 25 mph or more, and the operating limit sits at least 5 mph below the anchor design speed. The wind page has the numbers and where sources split.
• The paper says the wind limit and other restrictions must be on a permanently fixed information plate. The sheet adds a game safety rules plate.
• Per the paper, a trained attendant must supervise while the unit is inflated and "monitor weather and sustained wind speed, if operating outdoors." Attendants and installers are to be trained to assess wind with an anemometer, the Beaufort scale or another reliable method.
• For fire, the fabric has to meet the NFPA 701 flame test, with an extinguisher within 100 feet, a roof escape opening of at least 400 square inches on fully enclosed units, and blowers marked with horsepower, pressure and flow, with a non-return valve.

One number is disputed: the weight per tie-down. The fire sheet gives 75 pounds as the minimum weight per tie-down. Party Rental Insurance Advisors puts "75 lb" sandbags on hard surfaces under F2374. JumpOrange's anchoring guide says 75 pound sandbags suit only the smallest units in low wind and fall short of the force each anchor point must resist. We could not read the clause. Maryland's current rule sets "at least 75 pounds" of on-ground weight for bounce-type rides and 500 pounds for slides over 15 feet, which agrees with the fire sheet on the floor. Treat 75 as a floor, and follow the manual.

Oklahoma's labor department, describing what F2374 includes, adds trained attendants, minimum staff levels, daily logs and records, and deflation alerts plus impact mats for devices over 8 feet high. That is the agency's summary rather than the standard's text.

CPSC sets staffing. Its bulletin calls for at least one operator on a bounce unit or small slide, two on slides over 15 feet, and two on units for younger children, all with a direct line of sight. It adds that riders should be similar in size, shoes and glasses off, and the maker's maximum load respected.

Ohio and Oklahoma require it; Texas and Kentucky do not name it

State	How it refers to F2374
Ohio	"Inflatables specifically must meet ASTM-2374 guidelines." A ride that cannot show it "will not be able to be permitted." The Department of Agriculture inspects each device every 12 months and tags it, per the fire sheet above.
Oklahoma	The labor department's guide headlines "ASTM F2374 Compliance is a Requirement." Registration and inspection fees were cut to $1 per device each in 2025.
New Jersey	N.J.A.C. 5:14A-1.3 lists ASTM F 2374-10 among adopted standards, and makers must get type certification before selling a unit.
Maryland	The current chapter 66 text, revised by emergency provision in March 2026 and adopted in May 2026, applies ASTM F2374-22 with named sections excluded (units built before January 1, 2026 get a few more exceptions), plus its own wind and anchoring rules. The older PDF still posted on the Department's site names F2374-04.
Texas	The statute makes ASTM standards "as of May 1, 1999" the minimum. TDI's requirements page lists ASTM as an industry resource but names no inflatable standard. Your insurer's inspector does the inspecting.
Kentucky	An inspection tag valid for one year (2026 Acts ch. 23) and a $50 initial fee for air inflatables (302 KAR 16:020). The regulations we read do not mention F2374.

Texas and Kentucky show the other model: a state sticker or tag that proves an inspection happened, with the standard left to the inspector. The Texas guide walks through the sticker, and requirements has the other states. The Texas pages were read from dated Wayback copies (the statute as captured October 11, 2025 and TDI's requirements page as captured September 11, 2026), because tdi.texas.gov and the statutes site would not load from our network.

The journal paper counted 22 states with specific wind safety criteria as of the end of 2021, 19 of which explicitly require adherence to ASTM standards. It also says Florida includes ASTM standards in its regulation while excluding inflatables in its statute. We did not verify that Florida point, and our Florida guide sticks to the statute.

Whether your city enforces F2374 depends on its fire code

ASTM said in a 2021 release that the 2024 International Fire Code would require inflatable devices to be designed, anchored, operated and maintained under the manufacturer's instructions and F2374, and that the code is "in use or adopted in 42 U.S. states." Whether your city has adopted the 2024 edition is a local question. North Royalton's sheet cites F2374-22 and the permit guide shows how fire offices in other towns enforce their own versions.

Insurers point to F2374 and ask for paper

American Specialty tells buyers to purchase from a maker that is compliant with F2374 and to set up, operate and inspect "strictly in accordance with the manufacturers' specifications and ASTM F2374 standards." JumpOrange's insurance guide says insurers expect adherence.

Kelly Insurance Group is more specific about paperwork. It says carriers want annual third-party reports aligned with ASTM or ACCT for ziplines and trampoline parks, while for inflatables they expect "manufacturer-aligned inspection logs." Kelly's pre-submission checklist lists documented maintenance and repair logs and documented anchoring procedures. The coverage page covers the rest of the underwriting file.

Injury counts differ because the sources count different things

• CPSC's 2015 bulletin knew of 3,991 reported injuries, 12 of them deaths, from 2003 to 2013, and estimated about 113,272 emergency department injuries in those years, or 16,903 a year. Staff said the incidents were attributable "primarily to improper operation, supervision, and set up."
• A 2019 CPSC release estimated more than 18,000 emergency department injuries from bounce houses in 2018.
• A study in Pediatrics estimated 64,657 child injuries from 1990 to 2010, a 15-fold rise from 1995, and 31 children a day by 2010. Fractures were 27.5 percent and strains or sprains 27.3 percent.
• The journal paper counted 132 wind incidents worldwide from 2000 to 2021, with at least 479 injuries and 28 deaths.

Other pages round these off differently. A Skyscraper Insurance page says 11,000 injuries a year without a source, and an XINSURANCE page says over 2,500 people were injured in ten years. Use the agency and journal numbers above instead.
