MENLO PARK, Calif. (KTVU) - Facebook said Tuesday that authorities have determined that despite a sarin scare at a mail facility in Menlo Park, the test results came back for any "potentially dangerous substance."
In a statement, spokesman Anthony Harrison said that all the buildings at the facility at 1195 Hamilton Court have been "cleared for repopulation. Our rigorous security and safety procedures worked as intended to limit exposure and keep our people safe."
The news comes less than a day after Facebook's mail screening team deemed a package suspicious about 11 a.m. Fire Chief Harold Schapelhouman said sensoring technology used to inspect material at the site indicated the package might contain sarin.
Not knowing if the chemical was deadly, the FBI and hazmat specialists from the California National Guard's 95th Civil Support Team were called in to help out.
"The FBI and our law enforcement partners thoroughly tested the items in question and determined them to be non-hazardous," spokesman Cameron Rogers Polan said Tuesday in an email. "This collaborative effort took time, but ensured a most a careful and methodical testing was taking place to protect the public."
Sarin is a chemical warfare agent classified as a nerve agent, according to the CDC. The colorless, odorless liquid can also evaporate into a gas and spread throughout the environment. Symptoms can be as minor as drowsiness and cough to paralysis or even death.
