- 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
