A powder scare at a Southern Colorado post office Saturday when a worker's hands begin to swell after touching an envelope.
El Paso County Sheriff's deputies and FBI agents evacuated the post office after receiving a call about the employee.
Sources say there was some kind of powder on the envelope the worker was handling. He drove himself to the hospital but was soon released.
Authorities closed the post office for about 2 hours while they investigated.
The Belmont Station in Pueblo had its own scare in 2002 when 3 workers came down with a mysterious rash.
The skin irritations turned out not to be serious or related to any sort of biological or chemical agent.
