Two workers at Facebook’s HQ in California have possibly been exposed to sarin gas in the building’s mail room, fire officials say.
“We have two possible exposures but right now they are not exhibiting any signs or symptoms,” Menlo Park Fire Marshal Jon Johnston said.
The building, which is in Silicon Valley, has been evacuated.
FBI agents based in San Francisco are at the scene, a spokesman said.
Sarin is a toxic compound that disrupts the nervous system and has been used as a chemical weapon.
