Experts from Amazonas arrive at Innova to carry out expertise after a gas leak in Manaus Jucélio Paiva/Rede Amazônica Experts from the Technical-Scientific Police Department (DPTC) began, this Monday (20), forensic work at Unit 4 of Innova, in the Industrial District of Manaus, almost five days after the leak of styrene monomer, a substance considered toxic, from one of the product's storage tanks. The investigation seeks to clarify the causes and circumstances of the incident, which is being investigated by the Civil Police of Amazonas (PC-AM). The leak was recorded at 5:36 pm last Wednesday (15), at Innova's Unit IV, after the styrene monomer stored in the reservoir showed an abnormal increase in temperature. The company classified the occurrence as a "chemical emergency". According to the Amazonas Public Security Secretariat (SSP-AM), in this first stage, experts carry out a preliminary assessment of the area and use drones to record images and collect information to assist in the investigation. ?

Contained gas leak: firefighter confirmed the absence of residue and authorized activities In a note, SSP-AM also highlighted that the deadline for completing the investigation will depend on the volume of information and traces that will still be analyzed. “The report does not have a deadline for completion, due to the volume of information that will still be collected and analyzed together with the remains found at the site,” said the secretariat. At the same time, the Civil Police opened a police investigation, led by the 2nd Integrated Police District (DIP), to investigate all the circumstances of the case. The corporation informed that, for now, it will not disclose other information so as not to compromise ongoing investigations. Leak contained The Fire Department reported, on Sunday afternoon (20), that the teams that had been working at the site since last Wednesday (15) managed to contain the leak of gas considered toxic. According to the general commander of CBMAM, Colonel Orleilso Muniz, measurements carried out at the site indicated that there is no longer any emission of styrene gas. "At this moment, we have not found any residue of styrene gas in the surrounding area. Despite the containment, the Fire Department will continue working at the factory to maintain the tank's cooling. According to the commander, the work to remove the stored product and deactivate the structure could last months. Still on Sunday night, teams from the agency, Civil Defense and company technicians carried out a new analysis of the air quality regarding the presence of styrene gas in schools and companies in the surrounding area, which did not detect the presence of the gas. Monitoring in the region will continue on a preventive basis. Committee releases activities in factories in the Industrial District A committee formed by state bodies, in addition to the Superintendency of the Manaus Free Trade Zone (Suframa) and the Amazonas Regional Engineering and Agronomy Council (Crea-AM), decided to release the return of activities in industries in the Industrial Pole, in addition to state schools and public services as of this Monday (20). With the committee's decision, state schools that had their activities suspended in the Industrial District region will resume classes this Monday (20). The Citizen Emergency Service (PAC) Studio 5 also returns to normal operation. Industries in the Manaus Industrial Complex that had interrupted activities as a precaution are also authorized to resume operations. Lack of guidance Last Friday (17), Rosivete Ferreira, 63 years old, told g1 that the population living around Innova never received any guidance on how to act in the event of chemical accidents involving the industry. She said that she only discovered that there was a risk of an incident of this type after the leak. The domestic worker also reported that she presented symptoms compatible with the effects of exposure to styrene monomer pointed out by the head of the Chemistry Department at the Federal University of Amazonas (Ufam), Karime Bentes, hours after the incident. "I felt nauseous, very sick, a tightness in my throat and a headache. My eye felt like it was full of pepper, burning really bad", reported the resident.
