Many gas transmission companies dispose of their contaminated, out-of-service gas odorizers by simply capping them and putting the equipment in storage. A bleaching process using sodium hypochlorite solution is seen as a better alternative for decontaminating equipment. A brief overview of this process is presented.

Involved in sensing a panoply of physiological and environmental signals, including hormones, neurotransmitters, odorants, tastes and light, GPCRs are the targets of a pharmacopeia of drugs, from beta blockers to antihistamines. Until recently, however, high-resolution crystal structures were known for only the light receptor rhodopsin. Since the Hot Papers were published, researchers have worked out the architecture of several other GPCRs, including the closely related ß^sub 1^AR, a heart rate and blood pressure regulator.

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 end-users 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...
