Anaheim, CA (March 11, 2026) – Seven employees were taken to hospitals on Tuesday afternoon, March 10, following a hazardous materials incident at the Disneyland Resort in Anaheim.
Emergency units responded shortly before 12:30 p.m. to the Tomorrowland area near the Star Tours attraction after reports of an unknown odor backstage. Officials said the incident was linked to building materials used by a contractor that caused a reaction in the work area.
Several employees began experiencing dizziness and difficulty breathing. Seven workers were transported to local hospitals for evaluation, while several others were treated at the scene and later released. As a precaution, nearby guest areas were cleared during the response. The Space Mountain attraction was evacuated, and nearby locations, including the Star Traders shop, were temporarily closed while crews addressed the situation.
Officials confirmed that no park visitors reported symptoms, and the affected attractions and areas reopened later in the afternoon.
The incident remains under review by authorities.
Our thoughts are with those affected as they recover.
Hazardous Material Responses in Large Public Facilities
Areas with multiple access points near Tomorrowland can complicate emergency responses. When incidents occur in Anaheim, responders often focus on quickly securing the area and assisting those affected.
Hazardous material incidents may occur when chemicals or construction materials react unexpectedly. Even small exposures to fumes or airborne substances can cause symptoms such as dizziness, irritation, or breathing discomfort.
In large venues like theme parks, responders may temporarily close nearby areas while the source of the issue is identified. Clearing spaces and evaluating air quality can help protect workers and visitors while the area is made safe for normal operations to resume.
