Context

Background

CCAC's North Campus is located in McCandless, in Pittsburgh's northern suburbs. On the afternoon of April 3, 2025, a strong odor was detected in a hallway and reported to campus security and administration, prompting an evacuation of the building. According to WPXI, firefighters responded and determined the odor came from a staining chemical used in a lab. The college canceled all day and evening classes for the day as a precaution. The incident is a routine but instructive example of a non-violent campus hazard — a chemical smell from ordinary lab supplies — escalating to a full building evacuation and class cancellation, the kind of property/hazard event the archive deliberately captures alongside violent incidents.
