Inflatable Wind Speed Advisory

Inflatable Wind Speed Advisory

Every year there are numerous accidents involving inflatable devices getting tossed up in the air by strong wind gusts. Some of the incidents are freak weather events, while others could have been prevented if the operators had been keeping a better eye on the weather and the wind speeds.

Recent Inflatable Accidents Involving Wind Speed

On July 14, 2019 a strong wind blew a bounce house with three children 10 feet up into a power line. One of the children, a 9 year old named Lizzy later died from her injuries. The 911 call came in around 4 pm that day. According to “Time and Date” it looks like there were wind speeds of up to 22 mph during that time in Reno, where the accident took place. When the wind speed is between 19-24 mph all inflatable devices not meant for use over 25 mph need to be deflated immediately.
