Safety Recommendation R-01-005
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 and CP Recycling of Indiana management to develop and implement safe procedures for offloading toluene dissocyanate (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 RAILWAY PROGRESS INSTITUTE: Assist the Federal Railroad Administration and the Research and Special Programs Administration in the evaluation of the deterioration of pressure relief devices through normal service and the development of inspection criteria to ensure that the pressure relief devices remain functional between regular inspection intervals.

Safety Recommendation History
From: NTSB
To: Railway Progress Institute, Inc.
Date: 6/16/2011
Response: The NTSB is aware that, after AAR’s Tank Car Committee evaluated the data provided in 1,787 pressure relief valve inspection reports, it issued a new pressure relief valve inspection report and accompanying instructions, which were then incorporated into Appendix U of the 2007 edition of the AAR Manual of Standard and Recommended Practices – Specifications for Tank Cars, M-1002. Companion Safety Recommendation R-01-4, issued to the AAR, was classified “Closed—Acceptable Action” on August 19, 2010. Because the AAR’s actions addressed the issue, Safety Recommendation R-01-5 is classified CLOSED – ACCEPTABLE ACTION.

From: NTSB
To: Railway Progress Institute, Inc.
Date: 3/17/2003
Response: NMC# 102040: The Safety Board is aware through previous correspondence that a task force was formed to develop a protocol to determine the condition of pressure relief valves as they are removed from tank cars; task force members represent the RSI, the AAR, the FRA, RSPA, Transport Canada, and a valve manufacturer. The Board has been informed that the task force limited the scope of its activity to pressure relief valves in hazardous materials service, that a test form was completed and a pilot program initiated to validate the protocol, and that survey data is being received from participating companies. The Board commends the RSI and the task force for its ongoing efforts to examine this issue. As further information is developed, the Board would appreciate receiving an update on the task force's activities. In the meantime, Safety Recommendation R-01-5 remains classified OPEN -- ACCEPTABLE RESPONSE.

From: NTSB
To: Railway Progress Institute, Inc.
Date: 6/7/2001
Response: The Safety Board issued similar recommendations to the Federal Railroad Administration (FRA), the Research and Special Programs Administration (RSPA), and the Association of American Railroads (AAR). The Railway Progress Institute (RPI) has indicated that at a meeting of the AAR Tank Car Committee on April 25, 2001, a task force was appointed to address the Safety Board’s recommendation. Task force members represent the RPI, the AAR, the FRA, RSPA, Transport Canada, and a valve manufacturer. The RPI has indicated that it will advise the Safety Board of the conclusions and recommendations of the task force when its work is completed. Pending completion of the recommended actions, Safety Recommendation R-01-5 is classified OPEN -- ACCEPTABLE RESPONSE.

Response: Letter Mail Controlled 05/14/2001 6:00:19 PM MC# 2010408 - From Robert A. Matthews, President: In the investigation of the catastrophic rupture of a railroad tank car containing hazardous waste near Clymers, Indiana on February 18, 1999, NTSB issued Safety Recommendation R-01–05 recommending RPI assist the Federal Railroad Administration and the Research and Special Programs Administration in the evaluation of the deterioration of pressure relief devices through normal service and the development of inspection criteria to ensure that the pressure relief devices remain functional between regular inspection intervals. At a meeting of the AAR Tank Car Committee on April 25, 2001, a task force was appointed to address the NTSB recommendation. The task force includes members representing RPI, AAR, FRA, RSPA, Transport Canada and a valve manufacturer. We will advise you of the conclusions and recommendations of this task force when their work is completed. I hope this interim report on Recommendation R-01-05 is acceptable.
