CORTLAND, Ohio - In a matter of seconds, an unlicensed  bounce castle in China was swept away by strong winds in June. A three year old inside died.

A similar story in Florida in May, when a tornado tossed around an inflatable injuring three children.

"They're heavy when they're not inflated but when you put air into them they're light and can take off if not weighted or staked properly," said ODA Chief Inspector of Amusement Ride Safety Michael Vartorella.

So how can you protect your children in this summertime  staple?

Trevor Berry, Taylor Rental of Cortland owner, said "I would just say make sure they're state inspected and that it's a reputable company."

Entertainment Company Amberg Events recommends people remember the three W's- Weather, Workers and Warranty.

Jodi Hively, owner of Bounce-A-Round Rentals in Boardman said "If the wind is 15 mph or stronger we suggest that they bring the children out and shut the unit down just to be safe."

If your pants are flapping in the wind it's too windy.

"The one thing you should look for when you're  renting one of these is to make sure that every tethering  point or every hook up for a stake or weight has something  on it. It's illegal to not have something on it," said Vartorella.

Ohio inspects and licenses all commercial bounce houses annually. One of the requirements is that a trained worker has to be on duty.

If a parent signs a waiver at an open play session or while renting a bounce house, the parent becomes the trained worker. 

Supervision is key. One expert said that a lot of times  accidents happen whenever parents sign off to supervise but no one is actually watching.

"So have a couple of people trained as operators so  if somebody has to take a break or has something else to do, somebody else can take over. Big problem is one  person doing it and something else happens and they have  to leave it," said Vartorella.

Ask to see the warranty. Check their insurance and their state license. Their Ohio license should be on the blower. 

"That needs to be on there. If you don't see that,  then call my office," commented Vartorella.

Experts also remind parents to check the instructions, don't put different sized kids inside and don't overload the bounce house.

Some rules to keep in mind, before letting your child step foot into what should be a fun moment to remember.
