The fuel tank, in most cases, is deemed to be more impact resistant than a plastic equivalent used for storing petrol or diesel. Robin McKenzie of Millbrook (a General Motors company), says: "The EC 67R01 standard for testing LPG components stipulates that LPG tanks must have a pressure release valve." He adds: "This legislation ensures that storage and equipment used to supply LPG is extremely safe and meets exacting standards."

Regulations demand that LPG tanks are installed safely. This is achieved by securing the tank in position so it minimises danger if the vehicle collides or is hit under impact. Car manufacturers have a duty of care to conduct rear impact tests on all vehicles and this includes those fitted with an LPG tank. "A tank is made of much thicker steel than the car body. It therefore has to be anchored very securely," he says. "While the tank will not collapse or explode on impact, it will move position because it's extremely rigid in construction."

A common misconception concerning the highly flammable gas is the risk of explosion caused by sunlight, fires or heat.  LPG equipment supplier, Nicholson McLaren Engines (NME), says that tanks are designed to withstand high temperatures caused by direct sunlight or fire. An obvious fire risk is in the event of a vehicle accident. Manufacturers, however, have thrown down gauntlet to this risk by building tanks to extremely safe standards.

"A tank has a pressure release valve which is trigged if pressure exceeds a certain level. They also undergo a burst and a pressure test under the LPGA standards," says NME's John Waghorn. "Manufacturers and installers also ensure that the LPG fuel system under the bonnet is extremely safe and don't interfere with a vehicle's air bag system."

Adopting safe work practices under the bonnet require engineers to ensure all components are securely tightened and there are no gas leaks. According to Robin McKenzie, when LPG is injected into the tank it's less poisonous compared with petrol.

LPG and safety are indeed watchwords for manufacturers and installers. Those that install tanks and components that don't adhere to the stringent regulations run the risk of putting drivers in danger. Importantly, Fuelture and NME don't sell components or provide services that fail to comply with the 67R01 and the LPGA standards.

In summary, car manufacturers and LPG conversion service providers have a duty of care. When motorists endorse companies that adhere to strict safety standards, they will adopt one of the safest fuels available!
