A 15-year-old student at Benson Polytechnic High School in Portland, Oregon, has been hospitalised in critical condition after inhaling toxic gases produced during a chemical mixing incident.

According to the Portland Police Bureau, the student, whose identity has not been disclosed, mixed unspecified chemicals that resulted in hazardous fumes. Contrary to initial reports suggesting the boy had ingested the chemicals, police clarified that he had inhaled the gasses created by the mixture. Portland Police Chief Bob Day, who addressed the media on Wednesday, 9 September, stated that the teenager is expected to survive the incident.

The police department confirmed that an investigation is ongoing to ascertain how the student acquired the chemicals and the motives behind their use. The inquiry has so far involved extensive efforts, including numerous interviews, analysis of surveillance footage, review of social media activity, and the execution of search warrants to seize electronic devices.

Portland Fire and Rescue Chief Lauren Johnson described the situation as “unusual and complex,” emphasising the difficulties involved in ensuring the safety of hundreds of students and staff during the evacuation. The authorities deployed air monitors to assess the environment throughout their response to the incident. Johnson noted that the gases produced by the mixture were particularly pungent, making them detectable at low concentrations, below levels that would typically cause harm.
No other individuals at the school were reported to have suffered adverse effects from the gasses or required medical attention. Chief Johnson reassured the public that just because individuals could smell the chemical fumes did not imply they had inhaled a dangerously harmful amount.
During the press conference, Superintendent Kimberlee Armstrong expressed her gratitude to the school staff and Principal Curtis Wilson Jr. for their prompt actions in evacuating the premises. She commended the orderly conduct of the students during the emergency, highlighting the importance of safety in the school environment.
Armstrong also noted that while classes were cancelled for the day following the incident, arrangements had been made for students to collect their personal belongings, and classes would resume as normal the following day. The hazardous materials team had cleaned the affected areas, and air testing confirmed it was safe for occupancy.
In the aftermath of the incident, Portland Public Schools will implement a trauma intervention program to support students who may be struggling with the emotional ramifications of the event. The district aims to ensure students feel secure and supported in the coming days.
As investigations continue, the Portland Police Bureau has yet to release additional information regarding the circumstances leading up to the student’s actions. However, local authorities are committed to understanding the details surrounding this incident to prevent similar occurrences in the future.
Portland residents are reminded of the importance of chemical safety, particularly in educational environments, as the community reflects on this troubling event. The health and well-being of students and educators remains a top priority for the school district as it moves forward with its recovery efforts.
