Jumping for Joy Over Pressure

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities and you. In this blog we’ll discuss air pressure and safety in bounce houses.

Jumping for Joy Over Pressure

When the weather is nice and a special event warrants a bounce house, kids get a first-hand experience of the importance of pressure. The air-filled chambers allow bouncing, falling and a lot of fun. Maintaining the pressure requires a pump to run continuously and usually the required pressure is not measured or displayed because it has been predetermined in pre-production design and testing. Unlike a thick rubber tire, the relatively thin vinyl material of the bounce house only requires a few psi to elevate it above the hard ground. With names like Cloud 9 and Jump for Joy as suppliers, it is easy to see how the inflated structure takes children away from the normal day-to-day realities. However, safety is still an issue.

When safety in a bounce house is discussed, it usually involves parts per million (ppm) of potentially toxic materials  including lead or human contamination. According to one source’s analysis of a specific product, “Lead levels in the vinyl, the tests found, varied from 5,000 parts per million to 29,000, far above the federal limit of 90 to 300 parts per million.” Fortunately, pressure problems are not a concern, since under or over inflation are easily observed by both visual and audible (the pump’s noise) human sensing.
