2、dule Test Article, museum personnel claimed to be exposed to a small puff of brown/orange vapor, presumably oxidizer. The incident occurred August 23, 1998, when the museum technician was removing portions of lines that were not representative of flight configuration. The test article had been field
3、 decontaminated and checked for oxidizer contamination prior to shipment to the museum. It may be possible that some isolated portions of the system and offgassing from the flexhose softgoods may have been overlooked as potential sources of oxidizer.Lesson(s) Learned: 1. Spacecraft hardware and test
4、 articles used for public display must be thoroughly scrutinized for hazards prior to release to the public.2. The Lunar Module test article had been stored safely without incident for over 25 years. Personnel should resist the temptation to become complacent with items that are assumed to be safe.3
5、 Toxic vapor checks of large systems may not indicate the complete status of a contaminated system.4. Artifacts previously contaminated with a hazardous substance must be fully decontaminated prior to release to the public. This includes flushing of all portions of the system as well as removal of
