A Buffalo Wild Wings employee in Burlington, Massachusetts, died Tuesday after being exposed to cleaning chemicals, Burlington Assistant Fire Chief Michael Patterson told CBSN Boston.

Ten other people - two customers and eight employees - were hospitalized after being exposed to the chemical, which was identified by Patterson as sodium hypochlorite, a cleaning agent.
