If you inject the smelling agent Ethyl Mercaptan into propane will it be toxic and adhere itself to the metal tank?

Answer 1

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.

Answer 2

Ethyl Mercaptan itself is not considered toxic in the low concentrations used for odorizing propane. It may adhere to the metal tank if not properly managed, but it is unlikely to pose a significant health or safety risk when used for its intended purpose of providing a detectable odor to propane. Proper storage and handling procedures are important to minimize risks.
