Este estudo foi realizado para contribuir para o conhecimento de quais as principais causas dos acidentes em laboratório químicos e similares. Inicialmente realizou-se uma pesquisa bibliográfica para averiguar o que existia sobre este tema e concluiu-se que existe informação sobre acidentes em laboratórios químicos e similares, em especial indicações de boas práticas e descrições de acidentes de graves consequências, em que, a morte, em muitos, acabou por ser a consequência. No entanto, estudos alargados, com relevância estatística, de onde se possa inferir o tipo de acidentes de trabalho mais comuns em laboratório e suas causas não são frequentes. A nível mundial encontram-se na bibliografia alguns estudos sobre o tema mas estão relacionados apenas com entidades académicas. O objetivo deste estudo consistiu em determinar através de dados concretos fornecidos por pessoas com experiência na área tanto a nível académico como a nível industrial o que realmente acontece nos laboratórios a nível de acidentes de trabalho. Para tal foi criado e distribuído um questionário tendo-se obtido uma taxa de resposta de 80%, o que corresponde a 20 questionários preenchidos que reportam um total de 58 acidentes. A análise dos resultados indica que as consequências/danos mais frequentes em acidentes em laboratório, totalizando 73% dos acidentes são: 1) queimaduras térmicas, 2) cortes com material de vidro, 3)queimaduras químicas, 4) intoxicação e 5) irritação devido a agentes químicos pele e/ou olhos. Em termos de avaliação das razões para a ocorrência dos acidentes, a perceção das causas dos acidentes mais vezes reportadas, totalizando 82%, são: 1) manuseamento inadequado do equipamento, 2) fadiga / stress / falha humana, 3) falta de formação, 4) ausência de procedimentos ou procedimentos inadequados e 5) manuseamento de produtos intrinsecamente perigosos e/ou tóxicos.

Initially a bibliographical research was conduted to find out what existed on this topic and it is concluded that there is information of accidents in chemical and similar laboratories, specially indications of good pratices and descriptions of accidents with serious consequences, where death in many cases, was the consequence. However, extensive studies, with statistical relevance, of most common work accidents in the laboratory and their causes are not frequent. At the world level there are some studies on the subject, but they are related only to academic entities. The objective of this study was to determine, through concrete data provided by people with experience in the area, at academic and industrial level, what actually happens in laboratories in terms of accidents at work. For this, a questionnaire was created and distributed, with a response rate of 80%, wich corresponds to 20 completed questionnaires reporting a total of 58 accidents. The analyses of the results indicates that the most frequent consequences / injuries in laboratory accidents, totaling 73% of accidents are: 1) thermal burns, 2) cuts with glass material, 3) chemical burns, 4) intoxication and 5) irritation due to skin and/or eye chemical agents. In terms of evaluation of the causes for the occurrence os accidents, the most frequently reported causes of accidents, totaling 82% are: 1) inadequate handling of equipment, 2) fatigue / stress / human failure, 3) lack of training, 4) absence of inadequate procedures or procedures, and 5) handling of intrinsically hazardous and / or toxic products.
