| Abstract |
On May 1, 2001, a tractor-semitrailer that had horizontally mounted cylinders filled with compressed hydrogen struck a pickup truck near Ramona, Oklahoma. According to witnesses, the tractor-semitrailer then went out of control and overturned while continuing along the highway. It went off the road to the east and traveled 300 more feet before it stopped. During the process, some of its cylinders, valves, piping, and fittings were damaged and released hydrogen. The safety issues discussed in this report are the adequacy of Federal requirements for protecting cylinders that are horizontally mounted on semitrailers and the valves, piping, and fittings of the cylinders during rollover accidents and the adequacy of the information in the North American Emergency Response Guidebook about compressed hydrogen. As a result of its investigation of this accident, the Safety Board made recommendations to the Research and Special Programs Administration. |
