When liquefied petroleum gas (LPG) is stored and used in installations compliant with relevant health and safety legislation and industry codes of practice, it is a safe fuel. However, when it is not the results can be catastrophic. In May 2004 a gas leak from a corroded buried pipe led to an accumulation of gas in the basement of a Glasgow plastics factory. This resulted in an explosion which caused the building to collapse - nine people were killed and 33 were injured, some critically.
