Pictogramas do GHS e sua aplicação como ferramenta de comunicação de perigos para estudantes de graduação

Abstract: GHS PICTOGRAMS AS HAZARD COMMUNICATION TOOL FOR UNDEGRADUATE STUDENTS.Regularly, teaching laboratories use chemicals hazardous to health. Students must be aware of such hazards, to safely perform didactic experiments. The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is a hazard communication tool designed to harmonize the classification with a standardized labeling system worldwide. This work aimed at investigating whether undergraduate students correctly identify the hazards a… Show more

“…Alternatively, when asked to identify chemicals belonging to a specific hazard class using the elements displayed on the labels, the number of correct answers was reasonably higher, as previously observed by Uema and Ribeiro . The observed increase in the percentage of correct answers was probably due to the presence of the H-statements in the labels.…”

“…Only flame and environment pictograms achieved an acceptable interpretation (85% correct answers and less than 5% critical confusion) based on the ANSI Z535.3-2011 Standard . As consistently reported for other audiences, ,,,, the flame over circle pictogram was poorly understood and incorrectly interpreted as flammable. The health-related symbol exclamation mark was also poorly interpreted by the participants, as observed by Adane and Abeje…”

“…A maioria dos discentes não se valia dos rótulos dos produtos químicos para essa finalidade, e os alunos que usavam tais instrumentos não identificavam corretamente os perigos representados pelos respectivos símbolos. A pesquisa assinalou que, no campo da formulação do GHS, a maioria dos estudantes desconhece o significado dos pictogramas, pois estes não são autoexplicativos 18 .…”

“…Em nossa pesquisa, no inventário geral de resíduos químicos dos laboratórios estudados (I e II), representativos do ambiente acadêmico da instituição de ensino superior estudada, foram listados 40 itens, dos quais 38 (95%) são classificados como perigosos pelo GHS. Dos 10 códigos e frases de perigo mais frequentes, nove estão relacionados a características que conferem risco à saúde humana: H301 (19 ocorrências), H315 (18), H331 (18), H311 (16), H319 (16), H335 (14), H314 (13), H302 (11) e H317 (11). Apenas o código H225 (líquido e vapores altamente inflamáveis, 12 ocorrências) representa um perigo enquadrado como físico 6 .…”
