Why LPG cylinder painted Red?

LPG stands for Liquid Petroleum Gas. LPG cylinder painted Red in colour because as we know the wavelength of the Red colour is highest among all the colours in the spectrum due to which the Red colour can be seen from a far distance without any hurdle. Although Red colour is sign of danger or warning to us and LPG cylinder is highly flammable and can be blast due to minor mistake and It also use in Emergency situation due to which Red colour is selected than other to be painted on the LPG cylinders. LPG gas is also toxic in nature.
