General Notice: Odorant Fade in Railroad Tank Cars


Federal Register: 76FR 22381
 
Publication Date: 4/13/2012

Action:

Notice of Safety Advisory.

Summary:

FRA is issuing Safety Advisory 2012–01 to remind shippers and consignees of railroad tank cars containing odorized liquefied petroleum gas (LPG), of the importance of taking actions to ensure that a sufficient level of odorant remains in the LPG throughout the entire transportation cycle. FRA is issuing this notice to raise awareness within the hazardous materials community, of the potential consequences of having LPG reach endusers as under-odorized or essentially non-odorized material due to the diminishment of the added odorant during the transportation cycle (commonly known as ‘‘odorant fade’’). This safety advisory recommends that shippers and consignees of bulk quantities of odorized LPG review their existing LPG odorization standards and procedures, and take appropriate actions to guard against odorant fade in their shipments.
