Midwest Furfest Poison Gas Attack

Overview

Background

On December 7 2014, several thousand people, were evacuated from a Hyatt hotel in suburban Rosemont when an “intentional” chlorine gas incident at the hotel, which was hosting the Midwest FurFest convention, sent 19 people to hospitals early Sunday.

The incident happened around 12:40 a.m. at the Hyatt, at 9300 West Bryn Mawr Avenue in Rosemont, according to a statement from the Rosemont Public Safety Department. First responders were called to investigate a noxious odor that was spreading across the ninth floor of the hotel, where a high level of chlorine gas was discovered in the air, the statement said.

Nineteen people were transported to nearby hospitals after complaining of nausea, dizziness and other medical problems, according to the statement. All people inside the building were temporarily evacuated and sheltered at nearby facilities, including the Donald E. Stephens Convention Center.

Hazardous materials technicians found the source of the chlorine gas, what appeared to be powdered chlorine, in a stairwell at the ninth floor, according to a statement from police.
