16、es requirements in addition to those contained in parts 171, 172, 173, and 179 of this subchapter, to be observed with respect to the transportation of hazardous materials in or on rail cars. Amdt. 17426, 41 FR 16092, Apr. 15, 1976, as amended by Amdt. 17426A, 41 FR 40685, Sept. 20, 1976; Amdt. 1747
17、4, 58 FR 51533, Oct. 1, 1993 174.2 Limitation on actions by states, local governments, and Indian tribes. Sections 5125 and 20106 of Title 49, United States Code, limit the author-ity of states, political subdivisions of states, and Indian tribes to impose re-quirements on the transportation of haza
18、rdous materials in commerce. A state, local, or Indian tribe require-ment on the transportation of haz-ardous materials by rail may be pre-empted under either 49 U.S.C. 5125 or 20106, or both. (a) Section 171.1(f) of this subchapter describes the circumstances under which 49 U.S.C. 5125 preempts a r
19、e-quirement of a state, political subdivi-sion of a state, or Indian tribe. (b) Under the Federal Railroad Safe-ty Act (49 U.S.C. 20106), administered by the Federal Railroad Administra-tion (see 49 CFR parts 200 through 244), laws, regulations and orders related to railroad safety, including securi
20、ty, shall be nationally uniform to the ex-tent practicable. A state may adopt, or continue in force, a law, regulation, or order covering the same subject matter as a DOT regulation or order applicable to railroad safety and security (includ-ing the requirements in this subpart) only when an additio
21、nal or more strin-gent state law, regulation, or order is necessary to eliminate or reduce an es-sentially local safety or security haz-ard; is not incompatible with a law, regulation, or order of the United States Government; and does not un-reasonably burden interstate com-merce. 74 FR 1801, Jan.
22、13, 2009 174.3 Unacceptable hazardous mate-rials shipments. No person may accept for transpor-tation or transport by rail any ship-ment of hazardous material that is not in conformance with the requirements of this subchapter. Amdt. 17483, 61 FR 28677, June 5, 1996 174.5 Carriers materials and sup-p
23、lies. This subchapter applies to the trans-portation of a carriers materials and supplies moving by rail, except that the shippers certification is not re-quired when these materials and sup-plies are being transported by the car-rier who owns them. The requirements of this subchapter do not apply t
24、o rail-way torpedoes or fusees when carried in engines or rail cars. Railway tor-pedoes must be in closed metal boxes when not in use. Amdt. 17426B, 41 FR 57071, Dec. 30, 1976 174.9 Safety and security inspection and acceptance. (a) At each location where a haz-ardous material is accepted for trans-
25、portation or placed in a train, the car-rier must inspect each rail car con-taining the hazardous material, at ground level, for required markings, la-bels, placards, securement of closures, and leakage. These inspections may be performed in conjunction with inspec-tions required under parts 215 and
26、 232 of this title. (b) For each rail car containing an amount of hazardous material requir-ing placarding in accordance with 172.504 of this subchapter, the carrier must visually inspect the rail car at ground level for signs of tampering, in-cluding closures and seals, for sus-picious items or ite
27、ms that do not be-long, and for other signs that the secu-rity of the car may have been com-promised, including the presence of an improvised explosive device.

29、s, pyrotechnic, or incendiary chemicals in its design, and generally includes a power supply, a switch or timer, and a detonator or initiator. The carrier should be particularly attentive to signs that security may have been compromised on rail cars transporting materials covered by 172.820 of this
30、subchapter, rail carload quantities of ammonium nitrate or ammonium ni-trate mixtures in solid form, or haz-ardous materials of interest based on current threat information. (c) If a rail car does not conform to the safety and security requirements of this subchapter, the carrier may not forward or
31、transport the rail car until the deficiencies are corrected or the car is approved for movement in ac-cordance with 174.50. (d) Where an indication of tampering or suspicious item is found, a carrier must take appropriate action to ensure the security of the rail car and its con-tents have not been
32、compromised be-fore accepting the rail car for further movement. If the carrier determines that the security of the rail car has been compromised, the carrier must take action, in conformance with its existing security plan (see subpart I of part 172 of this subchapter) to address the security issue
33、s before forwarding the rail car for further movement. 73 FR 20773, April 16, 2008 174.14 Movements to be expedited. (a) A carrier must forward each ship-ment of hazardous materials promptly and within 48 hours (Saturdays, Sun-days, and holidays excluded), after ac-ceptance at the originating point
34、or re-ceipt at any yard, transfer station, or interchange point, except that where biweekly or weekly service only is per-formed, a shipment of hazardous mate-rials must be forwarded on the first available train. (b) A tank car loaded with any Divi-sion 2.1 (flammable gas), Division 2.3 (poisonous g
35、as) or Class 3 (flammable liquid) material, may not be received and held at any point, subject to for-warding orders, so as to defeat the pur-pose of this section or of 174.204 of this subchapter.

36、emoval and disposition of hazardous materials at destination. (a) Delivery at non-agency stations. A shipment of Class 1 (explosive) mate-rials may not be unloaded at non-agen-cy stations unless the consignee is there to receive it or unless properly locked and secure storage facilities are provided
37、 at that point for its protec-tion. If delivery cannot be so made, the shipment must be taken to next or nearest agency station for delivery. (b) Delivery at agency stations. A car-rier shall require the consignee of each shipment of hazardous materials to re-move the shipment from carriers prop-ert
38、y within 48 hours (exclusive of Sat-urdays, Sundays, and holidays) after notice of arrival has been sent or given. If not so removed, the carrier shall im-mediately dispose of the shipments as follows: (1) Division 1.1 or 1.2 (explosive) mate-rials: If safe storage is available, by storage at the ow
39、ners expense; if safe storage is not available, by return to the shipper, sale, or destruction under supervision of a competent person; or if safety requires, by destruction under supervision of a competent person. (2) Hazardous materials, except Division 1.1 or 1.2 (explosive) materials, in carload
40、 shipments: By storage on the carriers property; by storage on other than the carriers property, if safe storage on the carriers property is not available; or by sale at expiration of 15 calendar days after notice of arrival has been sent or given to the consignee, pro-vided the consignor has been n
41、otified of the non-delivery at the expiration of a 48-hour period and orders for disposi-tion have not been received. (3) Hazardous materials, except Division 1.1 or 1.2 (Class A explosive) materials, in less-than-carload shipments: By return to the shipper if notice of non-delivery was requested an

(a) When local conditions make the acceptance, transportation, or delivery of hazardous materials unusually haz-ardous, local restrictions may be im-posed by the carrier. (b) Each carrier must report to the Bureau of Explosives for publication the full information as to a
46、ny restric-tions which it imposes against the ac-ceptance, delivery, or transportation of hazardous materials, over any portion of its lines under this section.

47、rdous material for transportation or transport a hazardous material by rail unless that person receives a shipping paper prepared in accordance with part 172 of this subchapter, unless the mate-rial is excepted from shipping paper re-quirements under this subchapter. Only an initial carrier within t
48、he United States must receive and retain a copy of the shippers certification as required by 172.204 of this subchapter. This section does not apply to a mate-rial that is excepted from shipping paper requirements by this subchapter. (b) Each person receiving a shipping paper required by this sectio
49、n must re-tain a copy or an electronic image thereof, that is accessible at or through its principal place of business and must make the shipping paper available, upon request, to an author-ized official of a Federal, State, or local government agency at reasonable times and locations.
