We have a client who reported that a portable fire extinguisher exploded in one of their schools. Luckily enough, this occurred after hours and no injuries were reported.
It was a 10 lb. aluminum Carbon Dioxide cylinder manufactured by Luxfer Group Inc., Max operation pressure of 1800 psi and manufactured in 2009. Model 456. Failure occurred due to high internal pressure.
There was no fire in the building. Environmental factors [such as heat],maintenance of the cylinder and a failure of the pressure relief disc may have contributed to the cause of the failure.
I was wondering if anyone else had heard of this? Comments...
