The Lab’s Site Operations Center (SOC) receives more than 10 calls a month to 911. Most are misdials, and often the caller hangs up. The SOC will call back, and if no one answers, a security officer is dispatched. Instead of hanging up, please stay on the line to explain it was a misdial. https://sites.google.com/lbl.gov/emergencies/emergency-management/emergency-notifications
