Safety Recommendation History
From: NTSB
To: RSPA
Date: 10/28/1992
Response: In 1988 the Safety Board investigated an accident in Collier County, Florida, in which a cylinder containing poison gas was punctured by a steel plate attached to another cylinder. As a result of that investigation, the Safety Board issued the following safety recommendation to the Research and Special Programs Administration (RSPA) on March 23, 1990 (I-90-007). On September 24, 1990, RSPA responded to the Safet Board, stating that it intended to issue a riotice of proposed rulemaking (NPRM) concerning standards that "will require cylinders to be designed in such a manner that punctures during transportation are kept to a minimum." Safety Recommendation 1-90-7 was classified "Open--Acceptable Response" pending the issuance of a final rule; however, RSPA had not issued the NPRM as of September 3, 1992.The accident near Calhouri demonstrates that the potential for punctures from appurtenances extends to all types of hazardous material containers Therefore, the Safety Board believes that RSPA should expand its proposed rulemaking to require that attach merits to all DOT-authorized hazardous material packagirigs be designed to minimize the risk of puncturing other packagings during an accident situation. As a result of the revised safety recommendation issued with this letter, Safety Recommendation I-90-7 is classified as CLOSED ACCEPTABLE ACTION/ SUPERSEDED by Safety Recommendation I-92-002.

Response: RSPA RECOGNIZES THE NEED TO HAVE ATTACHMENTS TO CYLINDERS DESIGNED IN SUCH A MANNER THAT PUNCTURES DURING TRANSPORTA TION ARE KEPT TO A MINIMUM. AS PART OF OUR LONG RANGE RULEMAKING PLAN, WE WILL ADDRESS THE PROBLEM THROUGH AN NPRM WHICH WILL PROPOSE STANDARDS FOR APPURTENANCES ON CYLINDERS. BECAUSE OF THE CONSTRUCTIVE ACTIONS PROPOSED, WE REQUEST THAT RECOMMENDATION I-90-07 BE CLASSIFIED AS "OPEN ACCEPTABLE ACTION."
