A presente dissertação foi realizada na Navigator Tissue Rodão, pertencente ao grupo The Navigator Company (NVG), e insere-se no âmbito da atualização do Sistema de Gestão Segurança e Saúde
do Trabalho aos requisitos da nova Norma ISO (International Organization for Standardization)
45001:2018. O processo estudado foi a produção de papel tissue na área da Fabricação.
A execução do trabalho obedece a um objetivo explícito, a aplicação do Procedimento Geral 138
(PG138) para identificar os perigos, avaliar os riscos associados, e assegurar o tratamento do risco e da
oportunidade.
A metodologia aplicada encontra-se descrita no PG138, que consiste num procedimento sistemá-
tico, proativo e é aplicável a todos os sites e áreas florestais da NVG. Este procedimento sugere que os
perigos identificados podem ser classificados segundo 10 categorias de fatores. A avaliação destes riscos
conjuga a Probabilidade (P) de ocorrência com a Severidade (S) esperada, permitindo a determinação
do Grau de Risco (GR=PxS) de acordo com três níveis: Tolerável, Crítico e Importante. À metodologia
interna, foi acrescentada a classificação Europeia harmonizada, quer para os acidentes de trabalho (AT),
quer para as doenças profissionais (DP). As variáveis utilizadas para caracterizar o tipo de AT foram o
“Contacto”, o “Tipo de lesão” e a “Parte do corpo atingida”.
Do ponto de vista da segurança do trabalho, foi possível concluir com esta análise de risco (AR)
que o acidente típico “mais provável” poderia ser descrito como “queda de trabalhador, provocando
ferimentos superficiais ou então entorses e distensões, que podem afetar múltiplas partes do corpo”. Por
outro lado, do ponto de vista da saúde do trabalho, as doenças mais prováveis, parecem estar relacionadas com lesões musculoesqueléticas, perdas auditivas (por ruído), e doenças do trato respiratório, devido
à inalação de poeiras e fibras de celulose.
Esta análise evidenciou que os fatores de risco com maior influência em todas as áreas da Fabricação são os fatores mecânicos, os quais são relativamente semelhantes em todas as zonas, dada a natureza das funções, atividades e processos analisados serem também muito semelhantes.
O presente estudo apresentou como limitações: a delimitação à área de Fabricação; a impossibilidade de reavaliar o risco após implementação das (novas) medidas de segurança; impossibilidade de
comparação da sinistralidade da empresa com o subsetor C.1722 - Fabricação de artigos de papel para
uso doméstico e sanitário; e a experiência reduzida da própria analista em ambiente fabril, que pode ter
resultado na subavaliação ou sobreavaliação do risco.
Por outro lado, este estudo deu contributos úteis, tais como: a atualização da AAR de acordo com
o PG138 para a área da Fabricação; a integração de uma subcategoria de fatores de risco relativos ao
Comportamento Humano; a utilização da classificação Europeia harmonizada para os AT e DP; e, por
fim, o mapeamento que explicita a conformidade do PG138 com a Norma ISO 45001:2018.
This work was developed at the Navigator Tissue Rodão, part of The Navigator Company (NVG) group, to answer the need to update their Occupational Health and Safety Management System in accordance with the requirements of the new ISO 45001:2018 standard. The process studied was the production of tissue paper in the Manufacturing area. The aim of this study was the application of the “Procedimento Geral 138” (PG138) to identify hazards, assess the associated risks, and ensure the treatment of risk and opportunity. The methodology applied is described in PG138, which consists of a systematic, proactive procedure and is applicable to all NVG sites and forest areas. This procedure suggests that the hazards identified can be classified according to 10 categories of factors. The assessment of these risks combines the Probability (P) of occurrence with the expected Severity (S), allowing the Level of Risk (GR=PxS) to be determined according to three risk levels: Tolerable, Critical, and Important. To the internal methodology, the harmonized European classification was added, both for Accidents at Work (AT) and Occupational Diseases (DP). The variables used to characterize the type of AT were "Contact", "Type of injury" and "Part of the body affected". From the point of view of occupational safety, it was possible to conclude from this risk analysis (AR) that the "most likely" typical accident could be described as "fall of worker, causing superficial injuries or sprains and strains, which can affect multiple parts of the body". On the other hand, from the point of view of occupational health, the most likely illnesses are related to musculoskeletal injuries, hearing loss (due to noise), and respiratory tract illnesses due to the inhalation of dust and cellulose fibers. This analysis showed that the risk factors with the greatest influence in all areas of manufacturing are the mechanical factors, which are relatively similar in all areas given that the nature of functions, activities and processes analyzed are also very similar. The limitations of this study were: the fact that it was limited to the manufacturing area; the impossibility of reassessing the risk after implementing the (new) safety measures; the impossibility of comparing the company's accident rate with subsector C.1722 - Manufacture of household and sanitary paper products; and the analyst's own limited experience in a manufacturing environment, which may have resulted in the risk being underestimated or overestimated. On the other hand, this study has made useful contributions, such as: updating the AAR in accordance with PG138 for the manufacturing area; integrating an additional subcategory of Human Behavior risk factors; using the harmonized European classification for ATs and DPs; and, finally, mapping PG138's compliance with the ISO 45001:2018 standard.
