PORTLAND, Ore. (KOIN 6) — Concentrated drain cleaner being shipped through the United States Postal Service (USPS) started to leak Saturday night, which prompted two separate teams of hazards materials specialists to respond.
Firefighter Terry Foster said at 10:52 p.m. Saturday emergency personnel were called to the main transfer station for the USPS in the Pearl District. Crews found an unknown chemical that had leaked out of a package sent through the mail. Employees with USPS traced the package and determined it had been routed from the airport facility.
Airport fire crews responded to that location and found a second spill, Foster said.
The cleanup was finished around 1 a.m. No injuries were reported.
The case is still under investigation.
