Styrene Gas Leak at Innova Plant in Manaus Industrial District
Videos circulating on social media captured the moment a styrene monomer gas leak occurred at the Innova company's Unit 4 facility in Manaus's Industrial District on Wednesday, May 15th, at 5:36 PM. The incident prompted the evacuation of employees, who were seen gathering outside the building. The State Department of Health of Amazonas (SES-AM) reported that 16 individuals were treated at local hospitals for exposure, all in stable condition and undergoing medical evaluation. As a precautionary measure, employees from Innova and nearby businesses were evacuated from the area. Styrene monomer, a transparent, colorless liquid derived from petroleum or natural gas byproducts, is a synthetic industrial chemical produced for over 70 years and serves as a key raw material for the plastics industry. Following the event, Manaus Mayor Rento Junior declared a state of alert for the city. Approximately ten fire department vehicles, supported by 35 firefighters and company brigadistas, responded to the incident. The company confirmed that a chemical reaction within a styrene monomer tank at Unit IV led to the leak, with their internal brigade and the fire department collaborating on-site. The Commander-General of the Fire Department, Orleilso Muniz, indicated that safety valves were activated, suggesting a spontaneous internal chemical reaction as the likely cause, pending a technical investigation. The gas, being heavier than air, is expected to dissipate slowly. Health authorities advised the public to remain in well-ventilated open areas, keep windows and doors open, and turn off external air intake systems. Those experiencing symptoms such as eye or skin irritation, dizziness, headache, nausea, or respiratory issues were urged to seek immediate medical attention.
The styrene gas leak at the Innova facility highlights the critical importance of robust process safety management in the petrochemical industry. While the company and emergency services responded, the incident underscores the potential for unexpected chemical reactions within industrial storage, even with safety systems in place. Future considerations should include advanced predictive modeling for internal reaction risks and enhanced community communication protocols for industrial accidents. The event also serves as a reminder of the inherent risks associated with the production of essential industrial chemicals and the need for continuous regulatory oversight to ensure public and environmental safety in densely populated industrial zones.
