150 evacuated in San Bernardino, Calif., anthrax scare

More than 150 people were evacuated from the San Bernardino County Office of Aging and Adult Services in San Bernardino, Calif., on Wednesday following the discovery of a suspicious white powder in a piece of mail.

"We had county hazmat run a test on it to see if it was chemical or biological. That came up negative," San Bernardino City Firefighter Mike Arvizo told SBSun.com.

The white powder, which was described as a white residue contained on a mailed document, is not believed to have been anthrax or any other biological substance.

"San Bernardino County fire did an analysis of the substance that revealed it's probably methamphetamine," San Bernardino County sheriff's spokeswoman Arden Wiltshire told SBSun.com.

The white powder was discovered by a clerical staff member who was opening mail. The worker came across the residue on the document and alerted office personnel.

After the Sheriff's Department was notified, as many as 180 employees and clients were cleared from the building while hazardous materials personnel donned protective suits to enter the building.

Firefighters utilized masks and breathing apparatuses to enter the building. Monitors were then deployed to test the air for chemicals, radiation and oxygen levels.

"They'll test it and see what it is, but they said the chances of it being something dangerous are very slim," Jane Adams, deputy director for the Office of Aging and Adult Services, told SBSun.com.
