Na atualidade, e cada vez mais, a competitividade entre organizações é uma realidade crescente. A filosofia Lean já provou ajudar as empresas a melhorar a sua produtividade e reduzir desperdícios. A relação entre Lean e segurança, o Lean Safety, não é claramente entendida, o que está errado, uma vez que estas duas temáticas são compatíveis e ambas se esforçam para melhorar processos. As premissas básicas do Lean, oferecem possibilidades potenciais no tratamento da segurança e as Lean Tools têm impacto na segurança ocupacional. O objetivo deste trabalho prende-se nisso mesmo, explicar a relação entre Lean e segurança e tornar estes dois conceitos compatíveis através de um modelo de integração da segurança na filosofia Lean, uma metodologia designada por – Safety Stream Mapping (SSM). O SSM é uma metodologia inspirada no Value Stream Mapping (VSM) que permite, através da observação de um esquema a cores, perceber as áreas/processos pertencentes ao fluxo produtivo da organização, qual o risco associado e qual a causa da falta de segurança, facilitando assim a perceção da avaliação de riscos da empresa. Esta metodologia apresenta um conjunto de Lean Tools adequadas para o tratamento da falta de segurança, tendo em conta a causa associada à mesma. De forma a testar esta metodologia foram realizados dois casos de estudo em duas empresas diferentes. A implementação do SSM permitiu saber quais as áreas ou etapas do processo produtivo com maiores riscos ocupacionais, de uma forma intuitiva e de fácil interpretação, estando a avaliação de riscos de cada empresa resumida em apenas uma folha.
Nowadays, the competitiveness between organizations is a growing reality. The Lean philosophy has proven to help companies improve their productivity and reduce waste. The relationship between Lean and safety, Lean Safety, is not clearly understood, which should not be the case, since these two topics are compatible and both strive to improve processes. Lean basic assumptions offer potential possibilities for handling safety and Lean Tools have an impact on occupational safety. This work’s objective is to explain the relationship between Lean and Safety and to make these two concepts compatible through a safety integration model in the Lean philosophy, a methodology known as Safety Stream Mapping (SSM). The SSM is a methodology based on Value Stream Mapping (VSM) that allows, through the observation of a color scheme, to perceive the areas/processes belonging to the productive flow of the organization, what is the associated risk and what is the cause of the lack of safety, thus facilitating the understanding of the company's risk assessment. This methodology presents a set of Lean Tools suitable for the treatment of the lack of safety, taking into account the cause associated with it. In order to test this methodology, two case studies were carried out in two different companies. The SSM implementation allowed us to know which areas or stages of the productive process have the highest occupational risks, in an intuitive and easy-to-interpret way due to the risk assessment of each company being summarized in a single sheet.
