Space station's crew cleans up chemical leak

WASHINGTON - NASA briefly declared an emergency Monday morning aboard the international space station after a chemical leak of potassium hydroxide caused a strong odor and produced what the crew initially thought was smoke.


But NASA officials said the leak of the chemical, used in an oxygen-generating unit, was not considered a serious health threat to the three-man crew.


Michael Suffredini, head of the space station program, said the crew initially thought there was smoke, and possibly a fire, in the cabin. Crew members put on gloves and surgical masks and were told to place a charcoal filter into the ventilation system to clean the chemical from the station's air. In a short time, however, it was determined that the "smoke" was in fact vapor coming from the leak.
