Este artigo objectiva dar a conhecer os resultados de um estudo, realizado no âmbito do mestrado em Ergonomia na Segurança no Trabalho, o qual se centrou na análise comparativa entre 10 métodos de avaliação de risco, de natureza semi-quantitativa. Com este estudo, pretendeu-se investigar se o Nível de Risco obtido pelos 10 métodos era idêntico para cada um dos riscos previamente identificados e se o Tipo de Risco identificado poderia influenciar o Nível de Risco obtido por esses mesmos métodos.

In many enterprises the semi-quantitative approach turns out to be the available and most suitable technique to perform a risk assessment. Despite its advantages, we cannot disregard the existing gap in terms of validation of this type of applications. This paper reports a study about risk assessments' reliability, namely both inter-coder (reproducibility) and intra-coder (stability) reliability of the semi-quantitative approach. This study comprised 4 fundamental stages. Data collection relied on free and systematized observations and made use of video recording, documental research, analysis grids and questionnaires specifically developed for this purpose. A set of different analysts were asked to use four semi-quantitative risk assessment methods (in two different moments) to estimate and assess six risks identified in two tasks accomplished to produce Airbags. The Krippendorff's Alpha Coefficient (α<formula> _K</formula>) was the agreement measure selected to...
