Are LPG tanks safe?LPG tanks have always been designed and constructed taking into account the chemical-physical characteristics of the fuel. LPG tanks are built using 3.5mm steel sheets, heat-treated to avoid cracking in case of deformation (caused for example by an accident). The standards governing the construction of the various components are very severe. The tests and trials for tanks and pipes are performed at a pressure of 45 bar, although normally the operating pressure in vehicles never exceeds 20 bar.
