Item Acesso aberto (Open Access) Descontaminação de máscaras N95 em hospital público de Belém/PA: apresentação e avaliação de protocolo simplificado(Universidade Federal do Pará, 2024-11-25) MATTOS, Simone Lopes de; DIAS, Carmen Gilda Barroso Tavares; http://lattes.cnpq.br/2113791118142177he author presents a protocol for decontamination of N95 filter masks by means of short wave ultraviolet irradiation (UV-C), as well as the results of the microbiological validation testing of the UV-C device and qualitative research on the adherence of professionals from the João de Barros Barreto University Hospital, of the University Hospital Complex of the Federal University of Pará (HUJBB) to the aforementioned protocol. The microbiological tests demonstrated the efficacy of the decontamination protocol, as there was no bacterial growth in culture media inoculated with swabs of masks used in the hospital and decontaminated in the UV-C device, which proved the germicidal efficiency of UV-C irradiation. The results of the qualitative research point to the adherence of nursing professionals to the practice of mask decontamination, recognizing the practicality and contribution of the protocol to biosafety and occupational safety. As part of the same protocol, an alternative packaging for storing masks in the intervals of use of N95 masks is presented, considering their safe reuse. The protocol also has the following advantages: low cost and practicality of use, in addition to contributing to the reduction of infectious waste. Descriptors: Decontamination. Ultraviolet Rays.

This work presents a proposal for sustainable housing with the use of floors, blocks for sealing with thermo acoustic blanket and sustainable tiles. For their preparation, rotational molding and compression molding equipment was assembled. Residues of polymers and natural fibers were used to make these constructive elements. The polymers used for the development of the floor were polystyrene (PS) disposable cups; ecological blocks were modeled and processed from post-consumer polypropylene (PP) and high-density polyethylene (HDPE) packaging; tiles were molded from discarded laminates; the floors became resistant to abrasion due to the presence of babassu fibers. The blocks provided acoustic comfort by including açaí fiber blankets, the walls were assembled using blocks and a commercial product for laying and overlapping. Housing as a model for recycling materials discarded in the environment will be able to generate proper disposal, providing income, increasing the life cycle of these materials, producing ecological products in civil construction and meeting at least four of the Organization's Sustainable Development Goals-SDGs of the United Nations.
