Tampa, Florida – Tampa Fire Rescue units were called to the Post Office at 1900 East 12th Avenue in Ybor City on Monday, where employees reported a package leaking an unknown chemical.

Employees moved the leaking package outside, and one person who came into direct contact of the package complained of some mild irritation to his hands.

Local first responders began decontamination of employees as a precaution, but testing eventually determined the substance was eucalyptus oil.
