A coating company in Massachusetts, USA, experienced a chemical accident, and 16 employees were sent to the hospital for treatment.

According to a statement from the Hudson Fire Department, at 8:47 a.m. on that day, the fire department received an alarm from the involved factory and rapidly rushed to the scene. Upon arrival, rescue personnel found that multiple employees were suffering from physical adverse reactions, dizziness, eye inflammation, and irritation. The on-site command center immediately announced the activation of a Mass-Casualty Incident (MCI) emergency response. This term is a professional classification concept in European and American emergency regulation, referring to sudden situations where multiple casualties appear within a short period of time, exceeding conventional emergency disposal capabilities. There have been no reports of fatalities in this incident so far.

Emergency dispatch deployed eight ambulances to transport the 16 affected employees to three regional hospitals in batches. Firefighters entered the building to conduct atmosphere environmental monitoring. A preliminary assessment indicated that a chemical interaction process occurring within the factory was likely the trigger of the collective adverse reactions among employees.
