Facebook’s Menlo Park campus in Silicon Valley has reportedly been given the all clear after fears of a sarin exposure yesterday led to the evacuation of several buildings.
Menlo Park’s city fire marshal Jon Johnston told Reuters that exhaustive tests of the site had found no traces of toxic material, including of the deadly nerve agent sarin.
“There is no sarin,” Johnston told the news agency.
The scare started after automatic detectors used to spot dangerous chemicals and substances in Facebook’s mailing facility set off the alarm. Two individuals working at the facility were put under observation, reported Business Insider, but showed no signs of symptoms. Four buildings were evacuated in response and FBI agents were on the scene, said Facebook yesterday.
The company has previously been the target of at least one bomb scare, last December, which also led to the evacuation of buildings. The Verge has reached out to Facebook to confirm news of the all clear and will update this story as and when we hear more.
