Facebook Inc evacuated four buildings and two people were being evaluated for possible exposure to the nerve agent sarin on Monday after a package at the social media company's Silicon Valley mail facility tested positive for the toxic compound. "The (Facebook) facility tests all of the packages that come in and they had a positive test, so they just initiated their standard protocol. Facebook spokesman Anthony Harrison said the company evacuated four buildings following the positive test and was cooperating with police in the investigation. As of now, three of the evacuated buildings have been cleared for repopulation," Harrison said. Sarin, a potent toxic compound that disrupts the nervous system, has been used as a chemical weapon.
