News - KSC Toxic Fuel Leak Prompts Evacuation of Two Shuttle Hangars
Toxic Fuel Leak Prompts KSC Evacuation
POSTED: 4:31 pm EST November 6, 2006 http://www.local6.com/news/10256044/detail.html A leak of toxic rocket fuel prompted the evacuation of two shuttle processing hangars at Kennedy Space Center Monday but no workers were exposed to fumes or injured, NASA officials told Local 6 News partner Florida Today. The hydrazine leak was detected in Bay No. 1 of Orbiter Processing Facility, where the orbiter Atlantis is undergoing post-flight servicing and inspections. More than 100 people were evacuated from the hangar and nearby OPF Bay No. 2 as a precaution. Safety inspectors think the leak came from the shuttle's Orbital Maneuvering System. Technicians over the weekend were draining residual fuel from the system and removed a quick-disconnect line. Inspectors think an end-cap for the line apparently came off after work was completed, causing the leak. Hydrazine is used in combination with nitrogen tetroxide to power the shuttle's twin maneuvering engines in flight, Florida Today reported. An elevated level of the toxic fuel -- 60 parts per million -- was detected in the air around the engines, prompting the evacuation. "That's not what we consider a dangerous level. But with any reading above zero, we would take precautionary measures and evacuate the facility," said KSC spokeswoman Jessica Rye. |
