Safety Recommendation I-01-001
Details
Synopsis: About 12:05 a.m. on 2/18/99, railroad tank car UTLX 643593, which was on the west unloading rack at the Essroc Cement Corporation Cement Plant near Clymers, Indiana, sustained a sudden and catastrophic rupture that propelled the tank car's tank about 750 feet and over multistory storage tanks. There were no injuries or fatalities. Total damages, including property damage and costs from lost production, were estimated at nearly $8.2 million. The National Transportation Safety Board determined that the probable cause of the accident was the failure of Essroc Cement Corporation (Essroc) and CP Recycling of Indiana management to develop and implement safe procedures for offloading toluene diisocyanate (TDI) matter wastes, resulting in the overpressurization of the tank car from chemical self-reaction and expansion of the TDI matter wastes.
Recommendation: TO THE RESEARCH AND SPECIAL PROGRAMS ADMINISTRATION: Develop and implement policies and procedures to ensure that comprehensive reports concerning all significant failures of U.S. Dept. of Transportation specification tank cars, highway cargo tanks, and intermodal bulk containers containing hazardous materials are provided in writing to the Research and Special Programs Administration.

Safety Recommendation History
From: NTSB
To: RSPA
Date: 10/20/2004
Response: The Safety Board notes that in the HM-229 final rule, RSPA revised Section 171.16 to require more detailed information on packaging failures, including failures of bulk packaging such as that provided by rail tank cars, highway cargo tanks, and intermodal bulk containers. RSPA indicates that the revised form will enable it to collect more specific packaging information for each reported incident. For example, the new form requires the submitter to identify the specific packaging that failed and indicate the component of that packaging, how it failed, and what caused the failure. In addition, the report form includes information on the manufacturer, material of construction, manufacture date, most recent test date, and, where applicable, design and service pressure. The Board believes that the revisions to the written report form constitute an acceptable alternate approach to the intent of the Board's recommendation. Consequently, Safety Recommendation I-01-1 is classified "Closed--Acceptable Alternate Action."

From: RSPA
To: NTSB
Date: 4/1/2004
Response: In the HM-229 final rule, we revised $171.16 to require more detailed information on packaging failures, including failures of bulk packaging such as rail rank cars, highway cargo tanks, and intermodal bulk containers. The revised form will enable us to collect more specific packaging information for each reported incident. For example, the revised form requires the person submitting the report to identify the specific packaging that failed and indicate the component of the packaging that failed, how it failed, and what caused the failure. In addition, the report form includes information on the manufacturer, material of construction, manufacture date, most recent test date, and, where applicable, design and service pressure. Based on the revisions to the written report form, we request that you classify recommendation I-01-01 as "Closed-Acceptable Action."

From: NTSB
To: RSPA
Date: 1/23/2002
Response: The Safety Board understands that on July 3, 2001, RSPA issued an NPRM "Hazardous Material: Revisions to Incident Reporting Requirements and Hazardous Materials Incident Report" (HM 229) to revise the incident reporting requirements and the hazardous materials incident report form. These revisions are intended to increase the usefulness of data collected for risk analysis and management by government and industry and, where possible, provide relief from regulatory requirements. The Board has provided comments to that NPRM; a copy of those comments is enclosed. As we stated in those comments, the Board believes that adoption of HM-223 may limit the effectiveness of the proposals in HM-229 by excluding from RSPA reporting requirements those packaging failures that occur during loading and unloading operations. Pending further response on this recommendation and your decision on a final rule, Safety Recommendation I-01-1 is classified "Open--Acceptable Response."

From: RSPA
To: NTSB
Date: 5/31/2001
Response: Letter Mail Controlled 06/06/2001 1:14:35 PM MC# 2010461: On March 23, 1999, RSPA published an advance notice of proposed rulemaking under Docket HM-229. A copy is enclosed. In this notice, we asked a series of questions and solicited comments regarding revision of the current incident reporting requirements in the Hazardous Materials Regulations. We also requested comments on two NTSB recommendations (R-89-52, concerning shipper notification of hazardous materials incidents, and H-92-6, concerning identification of patterns of cargo tank equipment failures, including the reporting of all incidents involving DOT specification cargo tanks). The comment period closed on June 21, 1999. We have since evaluated all comments received and developed a notice of proposed rulemaking (NPRM). We expect to publish the notice by the summer of 200 1. We will consider Safety Recommendation I-01 -01 in this NPRM. We request that you classify recommendations R-01 -03 and I-01 -01 as "Open -Acceptable Action" pending further review, and re-classify recommendation I-00-6 [sic I-00-06] to"Open-Acceptable Action."
