LAWRENCE, Kan. (AP) -- University of Kansas officials say a graduate student who was poisoned after ingesting a toxic chemical while working in a lab didn't follow proper procedures.

The student accidentally ingested sodium azide, an odorless and colorless preservative commonly used in school labs. He was taken to intensive care in critical condition following the Nov. 4 poisoning and had to remain hospitalized for three days.

University officials haven't released the student's name but said he has apologized to his lab partners for the mistake.

Following the incident, the university evacuated Melott Hall and had Lawrence and Douglas County safety workers inspect the lab for hazardous materials.
