An unknown amount of the deadly nerve gas sarin was found Monday in a mailroom of a Facebook office in the US state of California. The building in question has been vacated.
Two people may have come into contact with the gas, but are currently not showing any symptoms, a forensic investigator from the local fire department told Reuters news agency.
Sarin can come into contact with the skin as a liquid and be inhaled as a gas. In both cases, the substance affects the nervous system, potentially resulting in fatal convulsions and paralysis.
