I have a classic Range Rover that I have owned for 20 years. About 10 years ago I had it converted to LPG and it has served me well. However an incident occurred yesterday which has left me concerned. I had finished filling up with LPG at my local garage and disconnected the filler pipe from the connection at the rear.

Instead of the usual small hiss of escaping gas a huge jet of LPG shot 8 feet across the forecourt. Clearly the non-return valve in the filling line had failed and the whole of my 90 litres of LPG was attempting to escape.

Fortunately I was able to put the filler pipe back on the fitting and apart from a bit of shock no harm done. I turned off the hand tap on the tank and all was well.

On enquiring from my installer I discovered that these systems have two non-return valves and in fact both had failed. There is no way of knowing if one has failed, thus the presence of two is only half a safety system. I thought I ought to report this to the Health and Safety executive as a vision of a ball of fire over a filling station filled me with horror.

Guess what? One cannot ring the HSE unless there has been a serious accident causing injury or death, and though they produce loads of forms for reporting accidents none of these are suitable for a member of the public to report an incident involving their own property. My local council was unable to assist me.
