Facebook evacuates offices after poison possibly detected at mailing facility


Facebook announced on Monday that four buildings on its property in Menlo Park, California, had to be evacuated after workers at its mailing facility possibly encountered the toxic nerve agent sarin.
Two people at the facility have been medically evaluated, and do not show symptoms of sarin exposure, CNN reports. Menlo Park Fire Marshal Jon Johnston said a mail scanning machine tested positive for sarin, but it could have been a false positive. Developed in 1938, sarin has no color, taste, or odor, and can evaporate from a liquid to gas.
Facebook said it is "conducting a thorough investigation in coordination with local authorities. As of now, three of the evacuated buildings have been cleared for repopulation."
