"A fourteen-year-old boy was killed after the chair he was sitting on exploded, propelling sharp chair parts into his rectum, causing extensive bleeding, which he succumbed to before medical attention could stem the flow.
The accident occurred when the boy was alone, sitting on the chair (which was for PC use); he managed to overcome the pain and call his father, who summoned an ambulance, but it took an hour to get him to hospital, by which time it was too late for him.
The chair in question was a standard gas cylinder type, where the height is regulated by an adjustable cylinder containing highly pressurised gas, and it was this which exploded, sending high velocity chair parts into the posterior of the unfortunate youth."
