hydrogen sulphidte
Cumbustible gasses in LPG (propane) cylinders have no odor, you cannot smell them. Gas producers add a perfume to the gas so that you can detect leaks with your sense of smell. These perfumes are gasses called Thiols (or Mercaptans) and contain sulphur, which is easily identifiable in tiny amounts by its pungent scent.
Not sure about chemical? But there are highly sensitivity alarm metres for detecting the leakage of liquid petroleum gas (LPG, butane, propane etc), and natural gas. One method I once used to find a leaking joint on a gas cooker was to apply washing-up liquid round the joints until a joint bubbling up pin-pointed the leak.
It is 28.316 lts of LPG.
LPG is a gas but a liquid petroleum gas.
LPG does not have any smell that is gas.

Yes, Liquified Petroleum Gas is a Gas. It is a mixture of butane and propane. Also ethyl mercaptan is added to LPG to detect the gas leakage.
Ethyl Mercaptane is C2H5SH. It is a sulphur containing organic compound. It is added into LPG so as to detect any leakage of LPG. The Pungent smell that comes from LPG is tht of ethyl mercaptane,otherwise LPG is an odourless gas.
Natural gas is odourless. Gas for domestic use - has chemicals added to create a smell, so leaks can be detected.
Helium is generally used; special spectrometers to detect helium leakage are designed.
We use the IC1 555 in LPG gas detector to detect the leaking gases.

LPG (Liquid Petroleum Gas) does not have its own odor. A powerful odorant, ethanethiol, is added to LPG so that leaks can be detected easily.

LPG is a mixed gas that are primarily contains propane (C3H8) and butane (C4H10)
Gaseous particles possess high speed and large spaces between them. Particles of LPG diffuse into these gaseous particles at a very fast rate and reach our nostrils. This enables us to smell the LPG.
