'We all ended up under the boat': what the testimonies of survivors of the accident at Iguaçu Falls say Survivors of the accident with a boat at Iguaçu Falls, which killed Dutch tourist Mark Lessink, aged 25, told the Civil Police that they did not receive guidance on how to act in an emergency before the start of the tour. The statements, obtained exclusively by Fantástico, are part of the investigation that investigates the circumstances of the vessel's capsize, which occurred last Tuesday (28). In addition to the dynamics of the accident, the police are also investigating whether the safety protocols adopted by the company responsible were sufficient. According to one of the survivors, the family received life jackets before boarding, but no explanation about the correct use of the equipment or the procedures in case the vessel capsized. "When we arrived at the boat, we were given life jackets that we needed to fasten at waist level. There was no explanation about how to use the vest or what to do if the boat capsized," he said in his statement. The lack of guidance was also mentioned by a witness. Karen Charlotte was traveling with her family. "There is no guidance if something happens. We weren't given guidance before. If you fall into the water, if something happens, lie on your back or something. Nothing like that." 'We all ended up under the boat': what the testimonies of the survivors of the accident at the Iguaçu Falls say Vests were also the target of criticism In addition to the lack of instructions, the survivors reported difficulties in remaining on the surface after the boat capsized. According to the statement, the model of vest used only tied at the waist, which caused the equipment to rise during the floating attempt. "There was a ribbon that fastened at the waist, but as it didn't fasten underneath, between the legs, the vest always rode up." According to the lawyer accompanying the family, the survivors faced difficulties staying on the surface because the currents of the Iguaçu River were strong. "They had extreme difficulty staying on top of the water. The chains led them downwards and the vest was not enough to keep them on top of the water," he said. 'There was no explanation about what to do if the boat capsized': survivors point out flaws in trip to the Falls Reproduction/TV Globo Investigation investigates possible flaws The Civil Police reported that, to date, they have found no evidence of irregularities in the actions of the vessel's two pilots. The investigations, however, began to analyze whether there were flaws in the safety protocols adopted before the tour. According to the delegate responsible for the case, the statements indicate that there may have been deficiencies in the instructions given to tourists. "We noticed, from witness reports, a lack of safety protocols, guidance on what to do when the vessel capsizes, on how to put on the vest and also how to check if it is in working order," he stated. The Scientific Police report concluded that Mark Lessink died from drowning. The investigation now seeks to identify whether managers of the operation can be held responsible for manslaughter. Company denies errors The company responsible for the tour reported that this week it carried out a refresher course with all employees on safety procedures. According to the company, the certifications obtained indicate that there is no need for changes and, therefore, the protocols remain the same. The company also disputed the Dutch family's report that there were no instructions before the tour. According to the concessionaire, tourists receive safety instructions at different stages of the experience. "There is a first briefing on the trailer, another on the suspended trail and, in addition, all visual communication through information signs in three languages. Before starting the tour, another safety briefing is carried out with specific instructions about the vessel", informed the company's administrative manager, Paulo Ricardo de Cordova. The company also refuted criticism made by survivors of the life jacket model used on the tour. According to the concessionaire, the equipment is of the "yoke" type and was designed to keep the victim's head out of the water, even in the event of loss of consciousness. "It has a surface on the side of the neck that, if the person is thrown into the water and becomes unconscious, prevents them from remaining with their head submerged and drowning," explained Cordova.
