Evacuations were ordered at Facebook headquarters in Menlo Park Monday afternoon, according to reports.
NBC Bay Area reports at least two people at a Facebook mailing facility may have been exposed to sarin gas through a suspicious package. The victims aren't presenting signs of being poisoned, the Menlo Park Fire District told NBC.
A hazmat crew is on the scene investigating whether the package contained sarin.
A spokesperson from Facebook told KCBS Radio two buildings in the Willow Village neighborhood were evacuated; the number of people who have left the campus is unknown.
Sarin "is a human-made chemical warfare agent classified as a nerve agent," according to the U.S. Centers for Disease Control and Prevention. "Nerve agents are the most toxic and rapidly acting of the known chemical warfare agents."
SFGATE reached out to Facebook and the Menlo Park Fire District and will update the story as more details become available.
From a Bay AreaSMS Alert Text:
Facebook's Menlo Park HQ has been evacuated. Bay area media reporting at least two people being evaluated for possible exposure to sarin. Monitoring..
Sarin is a human-made chemical warfare agent classified as a nerve agent. Nerve agents are the most toxic and rapidly acting of the known chemical warfare agents. They are similar to certain kinds of insecticides (insect killers) called organophosphates in terms of how they work and what kind of harmful effects they cause. However, nerve agents are much more potent than organophosphate pesticides.
