Firefighters continue cooling tanks after 41 hours More than 41 hours after the leak of styrene, a flammable and toxic substance, in an Innova factory, in the Industrial District, in the South Zone of Manaus, teams from the Amazonas Military Fire Department (CBMAM) continue to cool the tanks this Friday (17). According to the State Department of Health of Amazonas (SES-AM), 204 patients were treated in the state network until 10:30 am this Friday. The main symptoms reported were shortness of breath, nausea, headache, dizziness and fainting. This Friday (17), there is still the release of vapors from the chemical product, but at a lower intensity than that recorded at the beginning of the incident. According to the Fire Department, around 80% of the material that still comes out of the tank is made up of water particles, while the concentration of styrene is significantly lower compared to the time of the leak. For safety, an area of ??approximately 300 meters around the factory remains isolated. After a new assessment, firefighters will determine whether the activities of companies located nearby can be resumed. ? Join the g1 AM channel on WhatsApp The leak at Innova was recorded at 5:36 pm on Wednesday (15), after the product stored in the reservoir showed an abnormal increase in temperature. Styrene monomer, a substance released in the incident, is a toxic chemical used in the manufacture of plastics and rubber. The teams continue to work on cooling the external part of the tank and monitoring the internal temperature of the reservoir. Monitoring is carried out with laser equipment to prevent the product from reaching levels that could cause an explosion. According to the Government of Amazonas, 35 military personnel participated in the first containment work after the company was activated. Since then, firefighters have remained on site to ensure the safety of the operation. Patient care Of the 204 patients treated in the state network after the incident, 192 were discharged after evaluation and examinations. Another 11 remain hospitalized. SES-AM also recorded the death of a 67-year-old man who sought care after reporting discomfort caused by the effects of the leak. However, the department reported that the patient had a history of chronic respiratory disease and that no direct relationship was found between the death and the incident. Schools remain without classes As a preventive measure, the State Department of Education and School Sports (Seduc) kept activities in 12 state schools located in areas close to the scene of the incident suspended this Friday (17). Manaus City Hall also kept activities suspended in ten units of the municipal education network. According to the Municipal Department of Education (Semed), the return of classes will only occur after confirmation that there are safe conditions for the operation of schools. The affected municipal units are in the Parque Jardim Mauá, Mauazinho and Crespo neighborhoods. What is known about the toxic gas leak from a factory in Manaus Gas that leaked from a factory in Manaus is considered toxic and can spread over long distances, says expert Gas leak in Manaus: AM Public Prosecutor's Office investigates causes and impacts of the incident Pronto Atendimento ao Cidadão (PAC) Studio 5, which had interrupted services on Thursday (16), resumed operation this Friday. Companies in the Industrial District also adopted preventive measures on Thursday (16). g1 contacted the Metalworkers Union of Amazonas to find out if there were new releases or changes in the companies' activities, but did not receive a response until the last update of this report. Toxic gas leak in Manaus firefighters continue cooling tanks after 41 hours Reproduction/Rede Amazônica Isolated area and investigation The company located next to Innova was evacuated shortly after the incident, according to the Fire Department, and isolation continues to be maintained this Friday (17). Only teams involved in the operation, such as the Fire Department, Amazonas Military Police (PMAM), Civil Defense and health agencies, have access to the site. After the Fire Department clears the area, the Amazonas Civil Police (PC-AM), with support from the Technical-Scientific Police, will carry out an investigation to determine the causes of the accident. The main hypothesis put forward by firefighters is a spontaneous reaction inside the tank. "Everything is heading towards a spontaneous reaction inside the tank. Once the styrene molecule breaks, a chain reaction occurs that overheats the product", explained the colonel. According to him, if the safety valves were not activated, the reaction could cause an explosion or fire. "In the specific case of Innova, the tank's safety valves were released. This was what caused the leak observed in vertical jets, because the product was subjected to high pressure inside the reservoir", he stated. City Hall fines company R$ 4.5 million Innova was fined R$ 4,554,300 by Manaus City Hall after a technical inspection carried out by a task force formed by the Municipal Secretariat for the Environment and Sustainability (Semmas), Municipal Institute of Urban Planning (Implurb), Municipal Health Secretariat (Semsa) and Executive Secretariat for Civil Protection and Defense (Sepdec). According to the city hall, the company was fined in 30 thousand Municipal Tax Units (UFMs). During the inspection, it was identified that air pollution levels remained above the limit considered safe for human exposure. In addition to the fine, the company will have 20 days to present technical safety reports, contingency plan, emergency service plan, information on drainage and treatment capacity. After stabilizing the area, Implurb will also inspect the structure of the industrial unit. If irregularities are found
