The Research and Special Programs Administration is soliciting comments and information on ways to reduce risks posed by wetlines on cargo tanks hauling flammable liquids.
The agency, which is part of the U.S. Department of Transportation, said that since 1992 there have been seven reported accidents where unprotected piping on tankers ruptured when hit broadside by an automobile. Spilled fuel ignited, resulting in eight fatalities.
RSPA is trying to determine if changes to current safety regulations governing the design of cargo tanks are needed and if they can be done in a cost-effective manner. It has posed a series of specific questions covering current operation and characteristics of cargo tanks, current safety practices and their effectiveness, possible modifications to loading systems and procedures and possible alternatives to current design regulations.
The advance notice of proposed rulemaking and request for comments was published in the February 10 Federal Register which can be accessed at www.nara.gov/fedreg. Comments are due June 10 and can be submitted at http:dms.dot.gov. Reference docket number RSPA-99-6223.
