PORTLAND, Ore. (AP) — Six employees of a Portland hospital have suffered burns to their skin after opening an envelope containing a powdery substance.
Portland Fire and Rescue spokesman Paul Corah says the substance was being analyzed on-scene Wednesday night by emergency responders.
The ventilation system at the Portland Veterans Affairs Medical Center was shut down while the six people were quarantined and decontaminated.
The six workers — four hospital workers and two members of the security team — came into contact with the substance at about 4:35 p.m. on Wednesday.
