The mercaptan odor has been added specifically to assist in the detection of leaks.
If odor from the gas is noticed, the implication is that you have a leak. Attend to it promptly.
Varieties of LPG bought and sold include mixes that are primarily propane (C3H8), primarily butane (C4H10) and, most commonly, mixes including both propane and butane, depending on the season - in winter more propane, in summer more butane. So that people can smell the gas (for safety) chemicals that smell are added - ethanethiol, thiophene and amyl mercaptan.
That is not a very clear question. Are you asking if the materials left in a propane tank could be toxic if you use the tank for water? If so, then the answer is yes, but you are not going to be having a lot of ethyl mercaptan. An old propane tank can contain a significant amount of hydrocarbons, usually in the gasoline and diesel boiling point range.
LPG (liquefied petroleum gas) mainly contains a mixture of propane and butane gases. These gases are odorless and colorless in their natural state. To aid in leak detection, a distinct odorant is added to LPG to give it the characteristic smell.
When was mercaptan first added to gas in the U.S.?
A compound called mercaptan is added to LPG to detect its leakage. Mercaptan is a sulfur-containing compound that gives LPG a distinctive smell, making it easier to detect any leaks as it has a strong odor.
Liquified propane sold as fuel in the US must be at least 90% pure propane; the rest is typically butane, propylene (5% maximum) and ethyl mercaptan, which is added to give it a noticeable and characteristic odor.
Propane and butane. Some methanethiol (methyl mercaptan) is also added, giving a characteristic putrid smell to easily detect leaks.
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.

When produced propane and butane is odorless and colorless. Ethyl mercaptan is the odorant added to propane and butane in the processing and refining process to provide a detectable odor. Under certain conditions the odorant in propane may oxidize and lose its destictive odor. This odor fade can occur in new steel containers when first placed into service and in older steel containers that have been left open to the atmosphere. Air, water, or rust in a propane tank or cylinder can also reduce propane odor concentration. Ethyl mercaptan is toxic although the amount added to propane is non-threatening.

It has no odorAnswer:C4 (Butane) has no odor on its own but has odorous materials (Butyl- or methyl- mercaptan) added for leak detection.C-4 (the explosive) has a faint bituminous (oily) odor.
LPG (liquefied petroleum gas) mainly contains a mixture of propane and butane gases. These gases are odorless and colorless in their natural state. To aid in leak detection, a distinct odorant is added to LPG to give it the characteristic smell.
A faint odor around a propane fireplace could be due to gases like sulfur dioxide or mercaptan, added to propane for safety to detect leaks. It could also be from dust or debris burning off during initial use. Regular maintenance and ventilation can help reduce odors.
When was mercaptan first added to gas in the U.S.?
Propane itself is totally odorless. But due to its extreme flammability, a tiny amount of a highly potent "odorant" gas (usually methyl mercaptan, which smells like rotten eggs) is added before sale for safety. It is not practical to remove the "odorant".
