Overview
- Fire crews responded to an industrial building on Parmenter Road after employees pulled a fire alarm and reported dizziness, eye irritation and other serious symptoms.
- Responders declared a mass casualty incident and used atmospheric monitors that led them to conclude a chemical process likely contributed to the illnesses.
- Sixteen people were transported by multiple ambulances to three area hospitals and the nature of their injuries and current conditions have not been released.
- Hudson’s fire chief requested a hazmat team and the Massachusetts Department of Fire Services Special Operations delivered a rehab unit while neighboring towns provided mutual aid and station coverage.
- Investigators are still working to identify the specific process or contaminant and officials say their findings will determine exposure pathways, medical follow-up and any business or public safety actions.
