Even light winds can turn bounce houses into dangerous projectiles. Between 2000 and 2021, there were 132 wind-related bounce house incidents worldwide, causing 479 injuries and 28 fatalities. Shockingly, over one-third of these accidents occurred in wind speeds of just 0–20 mph – conditions most people consider harmless.
To prevent accidents, follow these key safety measures:
- Anchor securely: Use stakes or sandbags based on the surface.
- Monitor wind conditions: Use wind meters and evacuate if gusts exceed 15–20 mph.
- Follow safety standards: Adhere to ASTM guidelines and manufacturer instructions.
- Plan for weather changes: Check forecasts and have an emergency plan to deflate and secure inflatables quickly.
Bounce houses are fun, but without proper precautions, they can become serious hazards. By staying vigilant and prioritizing safety, you can ensure a safe and enjoyable event.
Bounce houses swept away by wind at parties and events. What regulations are in place to stop this?
Wind Risks for Inflatable Equipment
Understanding the dangers wind poses to bounce houses is crucial for preventing accidents. High winds can transform these inflatables into hazardous projectiles, leading to serious injuries or even fatalities. The lightweight materials, such as vinyl and PVC, make bounce houses particularly susceptible to wind, which can cause them to tip over, deflate, or even become airborne. This vulnerability underscores the importance of knowing and adhering to safe wind speed limits.
Wind-related incidents don’t just affect users inside the inflatables – they pose risks to bystanders as well. For example, wind can disrupt the airflow system of a bounce house, causing it to deflate and potentially trap or harm those inside. Even more alarming, strong gusts can lift an entire inflatable off the ground, turning it into an uncontrollable airborne hazard.
The dangers don’t stop there. Wind-blown bounce houses have caused accidents beyond the immediate area, including collisions with vehicles, power lines, and buildings, leading to highway crashes, fires, and power outages. Thomas Gill, an environmental science professor at the University of Texas at El Paso, recounted one particularly shocking incident:
"There was a case in Southern California where one of the bounce houses got picked up by the wind and dropped in the middle of a highway with a boy still inside the playhouse."
Safe Wind Speed Limits
Most bounce houses are designed to withstand maximum wind speeds of 15–25 mph. However, this is not a safety guarantee; it represents the upper limit before the structure is likely to fail. Professional operators often set much stricter limits to ensure safety. Delmy Montes-DeOca, owner of 2gether We Bounce, emphasizes:
"We won’t set up any inflatables if the wind is predicted at 15 mph or more for the day. We will simply cancel the event. Safety to us comes first before anything else."
Industry professionals like Gustafson recommend halting operations when wind gusts reach 20 to 25 mph. Research shows that a third of wind-related accidents occur at wind speeds of 20 mph or less. This highlights the importance of continuously monitoring wind conditions during events.
Main Causes of Wind Accidents
Many wind-related bounce house accidents are preventable and often result from inadequate anchoring, poor weather monitoring, or failing to evacuate as conditions change. A tragic example occurred in Waldorf, Maryland, on August 2, 2024. During a baseball game, wind lifted a bounce house 15 to 20 feet into the air, resulting in the death of a 5-year-old boy and injuries to another child.
Even when the weather appears calm, risks can still arise. John Knox, a geography professor at the University of Georgia, explains that incidents often occur during:
- Cool, sunny days following cold fronts
- Hot, calm days that create dust devils
- Summer days with distant thunderstorms
"There have been quite a few incidents in the Southwest U.S., where bounce houses haven’t just been blown around, but lifted into the air because of vertical motion of a dust devil taking it upward. That’s when it gets really dangerous."
The risks persist even after a bounce house is evacuated. Empty inflatables can still become airborne, striking bystanders or damaging property. For instance, a Ring camera in Hickory, North Carolina, captured footage of a bounce house being carried by the wind, narrowly missing a child. These incidents echo Kevin Lee’s caution:
"It’s definitely something parents need to understand and be aware that it is a very real risk."
These examples underscore why proper anchoring and constant weather monitoring are non-negotiable for inflatable safety.
Safety Standards and Rules
U.S. safety standards for bounce houses are designed to minimize wind-related accidents and ensure safe operation.
ASTM F2374 and Other Safety Rules
ASTM F2374 is the main safety standard for inflatable amusement devices in the U.S., covering their design, manufacturing, installation, operation, and inspection processes. The latest version, ASTM F2374-22, applies to land-based inflatables for dry, wet, or mixed use.
After reports of over 18,000 bounce house injuries in 2018, the CPSC worked on voluntary standards to emphasize the importance of proper anchoring to prevent inflatables from being lifted by wind.
"If a bounce house is not properly secured to the ground, a gust of wind can send it airborne with children inside and the result can be tragic."
Many states in the U.S. adhere to ASTM’s 25 mph wind speed limit for safe operation unless the bounce house is professionally secured. However, fewer than half of the states have specific laws regulating bounce houses. To address these risks, the 2018 revision of ASTM standards introduced updated anchoring and staking requirements, along with visibility guidelines for home-use inflatable play devices.
Globally, similar safety measures are outlined in BS EN 14960. These standards aim to bridge gaps between safety practices and manufacturer guidelines.
Manufacturer Instructions vs Safety Standards
Although ASTM standards provide a safety framework, manufacturers’ instructions don’t always align perfectly. Ideally, these instructions should match ASTM F2374, but differences can arise – particularly regarding wind speed limits and setup protocols. As Rich Powers ARM, Executive Vice President of Risk Services at American Specialty Insurance, explained:
"Organizations that choose to operate inflatable devices at their facilities need to be familiar with the risks involved, take the appropriate risk management precautions, and ensure that all inflatable attractions are set up, operated, and inspected following both manufacturer specifications and ASTM standards."
When there’s a conflict between manufacturer guidelines and ASTM standards, it’s safer to follow the stricter rule. For example, some manufacturers may permit higher wind speed limits than experts recommend. A 2022 study connected wind-related incidents to 479 injuries and 28 fatalities since 2000. Proper maintenance significantly reduces risks, with commercial inflatables showing lower incident rates compared to other amusement attractions. Adhering to manufacturer instructions can reduce accidents by 95%, while 80% of incidents stem from improper setup or lack of supervision.
In November 2024, Happy Jump highlighted that ASTM F2374 requires damaged inflatable slide components to be fully replaced to ensure safety.
To maintain safety, it’s critical to monitor wind conditions, secure inflatables properly, and conduct inspections regularly – daily, monthly, and annually.
Prevention: Anchoring and Weather Monitoring
Preventing wind-related bounce house accidents starts with solid anchoring and diligent weather monitoring. These steps help keep inflatables stable and participants safe.
How to Anchor Bounce Houses
A bounce house’s stability begins with proper anchoring. The two most common methods are stakes and sandbags, each suited to specific ground types and setup needs.
For grassy areas, stakes are your go-to option. Drive them deep into the ground at a 45-degree angle for maximum hold. Typically, 18–24-inch stakes work well for standard soil, but sandy areas may require longer stakes. Aluminum stakes are highly recommended for their reliability, though steel stakes are another strong option. Larger inflatables need at least three stakes to ensure even weight distribution and a secure setup.
"Secure anchoring is crucial. Use stakes or sandbags to prevent the bounce house from shifting in the wind." – Hero Kiddo Inflatables
On hard surfaces like concrete or pavement, sandbags are the practical solution. Use two or three sandbags per corner, depending on the bounce house’s size. Heavy-duty vinyl sandbags with straps are ideal because they attach securely and are easy to handle.
Choosing the right location is also key. Set up on level ground and look for natural wind barriers, like trees or buildings, rather than open, exposed areas. Throughout the event, check anchors regularly to ensure stakes stay firm and sandbags remain in place, especially after periods of heavy use or shifting weather conditions.
While secure anchoring is critical, it’s only part of the solution. Real-time weather monitoring is equally important.
Using Wind Meters at Events
Once the bounce house is anchored, monitoring wind speeds becomes your next priority. Wind meters provide real-time data, removing any guesswork. Handheld wind meters are particularly useful for frequent readings and quick responses. Assign someone to monitor conditions continuously, as weather can change unexpectedly.
If wind speeds reach 15–20 mph, deflate the bounce house immediately. The general safety cutoff is 25 mph – if winds exceed this, evacuate participants and shut off the blowers right away.
In addition to using wind meters, pay attention to environmental cues like swaying trees or flapping flags, which can signal increasing wind speeds. Stay updated with weather apps or local news, but always rely on on-site observations for the most accurate information.
When conditions shift, act fast. Be prepared to evacuate participants, turn off equipment, and secure or move the bounce house if needed.

Planning Events Around Weather
When it comes to outdoor events, being prepared for unexpected weather changes is just as important as securing bounce houses and monitoring wind conditions. A solid plan that includes weather contingencies can make all the difference in keeping everyone safe.
Checking Weather Before Events
Weather forecasts are your first line of defense against wind-related incidents. Monitoring wind speed is especially crucial before setting up any bounce house. Keep an eye on conditions well in advance to anticipate any potential challenges.
Focus on these key weather indicators: wind speeds, gusts, and storm systems. It’s important to confirm that wind speeds fall within safe operational limits before setup. Pay close attention to gusts, as they can often be much stronger than sustained winds.
"As a general rule, bounce houses should not be used when wind speeds exceed 15-20 miles per hour (mph), as recommended by most manufacturers and industry safety standards."
To stay informed, use multiple trusted sources like the National Weather Service, local meteorologists, and reliable weather apps. Watch for forecasts predicting high winds, heavy rain, or lightning. If wind speeds are expected to exceed 20–25 mph, it’s wise to postpone or reschedule your event. On the day of the event, double-check the weather conditions before beginning setup, as overnight changes can occur.
Having this level of preparation allows you to act quickly if the weather takes a sudden turn.
Emergency Steps for Sudden Wind Changes
Even with thorough planning, weather can shift unexpectedly. That’s why continuous monitoring is essential. Assign someone on your team to use a wind gauge and call for an immediate shutdown if winds exceed safe limits.
Professional event organizers are increasingly turning to advanced systems for better safety monitoring. For example, in Amsterdam in 2023, Fons van Egmond utilized two wind speed and direction sensors connected to WindPro. This setup allowed his team to track wind conditions both inside and outside a stadium from a central control room.
"I believe all outdoor events should have a tool like WindPro." – Fons van Egmond, Founder of Production Life
If wind speeds reach 15–20 mph, begin emergency procedures. Should winds exceed 24 mph (Force 5 on the Beaufort Scale), evacuate immediately. Your emergency plan should include removing all participants from bounce houses, turning off blowers, and starting deflation immediately. Staff should be stationed at each inflatable, ready to act within seconds.
Use clear and audible signals, like whistles or air horns, to ensure all staff members understand their roles in an emergency.
During a busy weekend in July 2023, Fons van Egmond deployed six WindPro devices to monitor multiple events simultaneously. His team accessed real-time wind data remotely through the WindPro Web Portal and received instant alerts via email or browser notifications.
"Even in moments of internet disruption, weather warnings remain accessible, making the machine invaluable." – Fons van Egmond, Founder of Production Life
Consider investing in automated alert systems that notify you when wind speeds cross critical thresholds. These systems can send real-time warnings to mobile devices and display alerts, giving you precious seconds to respond to dangerous conditions.
