No.: 06-0058\nFerrellgas\nLiberty, MI 64068\nOne Liberty Plaza\nMr. Warnell:\nThis is in response to your letter requesting clarification of tank car unloading requirements\n180). Specifically, you ask if a steel gate or a steel locking arm may be used to satisfy\nprovided in § 173.31(g) of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-\n§ 173.31(g)(1), requiring the unloader to secure access to the track to prevent entry by other\nrail equipment.\nIn accordance with § 173.31(g)(1), examples of devices capable of securing access to the\ntrack and preventing entry by other rail equipment would be derails, lined and blocked\nswitches, portable bumper blocks, and other equivalent equipment. For equipment to be\nequivalent to those specifically mentioned by example, it must be capable of protecting the\na steel gate arm or other formidable barrier capable of stopping or diverting rail equipment\nunloading operation by diverting or stopping rail equipment. In our opinion, a locked gate or\nand providing the same level of protection as a portable bumping block, derail, switch or\nsimilar device would fulfill the requirements of 173.31(g) (1).\nI hope this information is helpful. Please contact us if you require additional assistance.\nSincerely,\nCher Smart Development\nOffice of Hazardous Materials Standards\n173-31(911)\n060058\n\n<<<PAGE 2>>>\n\nSupko\n§173.31 69 1)\nTark Cars\nFerrellgas\n06-0058\nMarch 2, 2006\nMr. Edward T.
