Exploding Lead-Acid Battery Powered Wheel Chair

In 2008, an overhead cabin on a plane landing in the U.K. reportedly started to spark up. Blue sparks came out as the cabin was opened, and caused panic. The wheel chair was immediately taken out of the plane to a vehicle, where it caught on fire and explode. The reason was the Lead-Acid battery in the Wheelchair. This was due to overheating, as the device and battery were never unplugged. When overheated, hydrogen and oxygen in the battery builds up, and usually comes out of a vent. But, the vent wasn't working properly, and the wheelchair itself was confined in a cabin, so the accumulated gases caused sparks, and eventually, an explosion. The force can blow up the casing, cause shrapnel, and spraying acid, which is most dangerous. The way to prevent this, is to always unplug your batteries from your devices. Never let it heat up, and always take it to a company to check it. Also, contact airline companies, and other public service related offices/companies to see what you can do to ensure safety.
