STENNIS SPACE CENTER -- Five employees from the Navy's Fleet Survey Team at Stennis Space Center were in quarantine at Stennis Space Center on Wednesday until local police units determined a white powdery substance found is calcium carbonate, or talcum powder.
A bag with the white substance was found about 9:30 a.m. at the team's office. The five who were in the office at the time were quarantined, said Cathy Willis, public affairs officer for the Navy's Oceanographic and Meteorological command at Stennis.
Local emergency officials responded and Willis said the Biloxi Police Department, working with the Gulfport Police hazardous materials team, identified the substance shortly before 2:30 p.m.
Other operations at Stennis were not affected, she said.
