No.: 08-0243 Dear Mr. Lovelace: This responds to your letter dated September 19,2008, regarding requirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 17 1 - 1 80) that apply to the placement of hazard warning labels on propane cylinders. You state that as a propane marketer and refiller of 20 pound cylinders, your company has placed over 900 "Flammable Gas" labels on propane cylinders. The cylinders at issue have never had the Flamm.able Gas label affixed to the cylinder (neck) for transportation, although they had contained Propane prior to customers bringing them in for refilling. You ask if your understanding is correct that a cylinder containing Propane should have a Flammable Gas label permanently affixed to the cylinder (neck), rather than on a removable "plastic sleeve" placed around the body of the cylinder that displays the Flammable gas label among advertisements. It is unclear whether you are addressing the placement of the Flammable Gas label on the neck of a cylinder that contains propane or cylinders that have been emptied and no longer represent a flammable gas hazard in transportation, but are brought to your company for refilling. Generally, a hazard warning label must be printed on or affixed to a surface (other than the bottom) of the package or containment device containing the hazardous material, and located on the same surface of the package and near the proper shipping name marking, if the package dimensions are adequate. As prescribed in § 172.400a(a)(i) and (ii) of the HMR, a hazard warning label is not required on a cylinder containing a Division 2.1,2.2 or 2.3 material that is not overpacked and durably and legibly marked in accordance with CGA Pamphlet C-7, Appendix A; that is, a neck ring, label may be used on a cylinder in place of a hazard warning label. A hazard warning label may be printed on or placed on a securely affixed tag, or may be affixed by other suitable means to a: 1) package that contains no radioactive material and that has dimensions less than those of the required label; 2) cylinder; and 3) package with such an irregular surface that a label cannot be satisfactorily affixed. Therefore, a removable "plastic <<>> sleeve" affixed to, or placed around the body of the cylinder that displays the Flammable Gas label for Propane is acceptable (See § 172.406). Cylinders that are emptied and cleaned and purged of residue and that no longer pose a hazard in transportation must be shipped in accordance with the empty packagings requirements prescribed in § 173.29. I hope this information is helpful. If we can be of fiuther assistance, please contact us. Sincerely, Charles E. Betts Chief, Standards Development Office of Hazardous Materials Standards <<>> Eflgrur~l 3 /72/ 406 LOVELACE GAS SERVICE, INC. 3/72 n 4 0 0 4 I0606 East Colonial Drive Orlando, Florida 32818 5 /72*+04 h h c h y li&-oaqz Office of Hazardous Materials Standards U.S. Department of Transportation 1200 New Jersey Ave, SE Washington, DC 20590 Ref: Labeling of DOT 4BA, 20# Propane cylinders To Whom It May Concern: We are a Propane Marketer and refiller of 20# propane cylinders. In the last several months we have had to place over 900 DOT UN1075 Flammable gas labels on propane cylinders. Those cylinders have never had the label affixed to cylinders for transportation, even though they had contained propane prior to customers bringing them for a refill. It is my understanding those labels should be permanently affixed to cylinders, so they cannot be easily removed and be readily visible to the consumer. However, others seem to believe it is not necessary to have the label affixed to cylinder, if plastic sleeves have printing of a label among the advertisement on sleeves. Plastic sleeves are not durable and a hindrance for visual inspection of cylinders before refilling. Therefore, must be removed for cylinder inspection. We have found when plastic sleeves have been added to 20# cylinders containing propane, there is substantial evidence that rust can form on cylinders caused by the plastic sleeves. This does not occur to cylinders, when plastic sleeves have never been on them. It would appear to me, the Hazardous Materials Regulations "Transportation" should be interpreted as requiring a permanent type label affixed on 20# cylinders for transportation when containing propane. This is because a 20# cylinder can be refilled many times and last several years. Therefore, I question, the logic of substituting permanent labels for temporary labels on nondurable plastic sleeves. The "transportation," label printed on plastic sleeve, is not visible from the front of cylinder where the consumer would normally view it during use. I would appreciate your assistance helping me to properly interpret the regulations in this matter. Sincerely, 17 ,U/~-L "Bill" Lovelace, Sr. <<>> This is one example, of why the "cylinder exchange world" would not end without plastic sleeves on cylinders. As you can see, the warning and label for "Transportation," are visible for consumer to see, no obstructions on cylinder, leaves it easy for a visual inspection and it has no plastic sleeve on it to result in rust. <<>> state, ai califomia to causoc inders that do not C can almacene; propane, Slustedo, unless tamper ovident cap or ane: Que so a bombora no se ha rellens calentadores, rad adores o hut 3 recreacionalesty en ouos it lame al servicio de bomberos No Intente hacer rep oLP Gas pesa más que elairo y uede deposiasa en ol contacto conci contenido en estado iguido cab o No pernita que los ninos se acerquen O jueguen cor o Solo para uso en extenores."
