  • LPG is a liquid under pressure but a gas at ambient conditions.
  • Vapour LPG is twice as heavy as air.
  • Liquid LPG is half as heavy as water.
  • LPG is colorless.
  • LPG has a low boiling point of - 6°C
  • LPG has a narrow flammability range between 1.8 to 9.5% in air.
  • Flash point of LPG is -60°C.
  • The approximate minimum ignition temperature of LPG is in the range 410°C to 580°C. LPG is odourless.
  • Ethyl Mercaptan is added as an odourant to detect LPG in case of leaks.
  • LPG is non-toxic.
  • It is lightly anaesthetic and can cause suffocation, if present in sufficiently high concentrations.
  • Liquid LPG can cause severe cold burns to the skin owing to rapid vapourisation and the consequent lowering of temperature
