Cartazes e cartilha: recursos didáticos para a conscientização sobre o uso seguro de produtos de limpeza

Abstract

Cleaning products are essential preparations for sanitizing and disinfecting various environments, playing a crucial role in the removal of bacteria and dirt. However, improper use and incorrect mixing of these sanitizers pose potential risks to human health and the environment. The challenges are directly related to the lack of knowledge about the handling and erroneous mixing of these substances, highlighting the need for awareness regarding the risks of homemade mixtures and the safe use of household cleaning products. In light of this, the present study aimed to promote awareness and interest in the risks of improper mixtures of cleaning products through the creation and use of posters designed by high school students. These posters were later utilized to create an informative booklet containing clear and accessible guidelines on the risks associated with the improper handling and combination of these sanitizers, aiming to prevent possible accidents and harm to the health of students and the school community. The research was conducted with 29 students from the 2nd year of high school at EEFM Professor Hermenegildo Firmeza through a didactic sequence involving several steps. The evaluation of the work took place through data collection in two phases. First, a survey questionnaire was administered to assess the students' perception of the topic addressed. After the first day of work, the researcher developed an informative booklet based on the posters created by the students during the activity, aiming to consolidate the knowledge acquired by the students in an accessible and didactic manner. On the second day of the project, the students presented their posters in groups, and a second questionnaire was used to evaluate the effectiveness of the project and the assimilation of the content by the students. Finally, through the analysis of the data obtained from the surveys and perception questionnaires, it was possible to conclude that the booklet was well-received and significantly contributed to the students' understanding of the dangers of mixing cleaning products, the reactions involved, and the harmful effects that these mixtures can generate. The majority of students reported an increased awareness and ability to handle these products in their daily lives, as well as greater confidence in disseminating this information among their family and friends
