Posted By patrick o brien I have heard that when electric wheelchairs are being charged that hydrogen gas is given off. Any views on this.

Posted By Maggie Atterbury Paul is spot on. The rules for charging a heavy duty wheel chair battery is the same as any other similar battery - it must be done in a well ventilated area Maggie Atterbury

Posted By J Knight Hi Paul, Gel batteries, as has been pointed out, have vanishingly small emissions and can be charged fairly freely. However, having said this, we ensure that dedicated wheelchair charging rooms are well ventilated; the bets systems have extractor fans which operate as soon as a charging socket is turned on. This is for two reasons; 10 a very small number of wheelchairs still have lead acid batteries so it's best to be prepared in case somebody acquires one of these and ii) gel batteries can fail, in which case they evolve H2S. The latter happened in a Care home managed by my former employer; people spent a week thinking it was the drains. Single gel battery equipped wheelchairs are often charged up in bedrooms; I haven't heard of anybody having a regulatory problem with this, except sometimes Care Standards get upset and you have to watch for maintenance of access and egress, John
