Chemical Reaction at Disneyland Sends Seven Workers to Hospital

Building contractor materials caused an unexpected chemical reaction in a backstage area near Star Tours, prompting a hazmat response and temporary evacuation of parts of Tomorrowland.

Hazmat Teams Respond to Tomorrowland Incident

What started as routine renovation work at Disneyland turned into a medical emergency Tuesday afternoon when building materials triggered an unexpected chemical reaction. Seven employees were hospitalized after inhaling toxic fumes in a backstage area behind the Star Tours attraction in Tomorrowland.

The incident unfolded around 12:30 p.m. when workers noticed a strange, noxious odor emanating from construction materials being used by a contractor. Within minutes, employees began experiencing dizziness and shortness of breath – classic symptoms of chemical exposure that I’ve witnessed covering industrial accidents across Europe.

Emergency Response and Evacuations

Anaheim Fire Department hazmat crews arrived quickly at the Anaheim theme park, their white protective suits a stark contrast to the colorful backdrop of Disney’s futuristic land. Sergeant Matt Sutter of the Anaheim Police Department confirmed that first responders evaluated the contaminated area while paramedics treated affected workers.

Several employees were treated on-site and released, but seven others required hospital transport for further evaluation. Their current conditions remain unknown, though officials described the symptoms as ‘minor’ – a term that, in my experience covering chemical incidents, often understates the potential long-term effects of toxic exposure.

Guest Areas Cleared as Precaution

Out of what Disney officials called ‘an abundance of caution,’ large sections of Tomorrowland were temporarily evacuated. The Star Traders shop connected to Star Tours was closed, with cast members blocking entrances while hazmat teams worked.

No guests reported symptoms or injuries, according to police. This detail matters enormously – in chemical incidents, the difference between backstage and public exposure can mean the difference between a workplace accident and a mass casualty event.

Construction Materials Under Investigation

Disney officials confirmed that building materials used by an unnamed contractor caused the reaction, though they haven’t specified which chemicals were involved or the exact nature of the reaction. This lack of detail is typical in the immediate aftermath of such incidents, as investigators work to determine what went wrong.

Having covered similar industrial accidents, the pattern is familiar: routine construction work, unexpected chemical interaction, workers overcome by fumes. What’s unusual here is the setting – the ‘Happiest Place on Earth’ transformed temporarily into a hazmat zone.

Normal Operations Resume

By 3 p.m., the affected areas had reopened and normal park operations resumed. Space Mountain, Star Tours, and Star Traders were all back in business, the earlier drama reduced to yellow caution tape and the lingering smell of industrial cleaning agents.

The incident serves as a reminder that even in Disney’s carefully controlled environment, the realities of construction and chemistry can intrude. For the seven workers now in local hospitals, Tuesday’s shift at the Magic Kingdom ended very differently than they’d planned.
