RESUMO

A review of the norms and technical precautions referring to the bio-safety in forensic DNA research laboratories was made in the present study. The laboratory for extracting, analyzing and digesting the DNA is a place of constant learning and risks for the teams who work there. Knowing such risks is the most efficient way to avoid them and that is a necessity. It was tried to gather as much information as possible aiming to minimize such risks. Those are divided in physical, biological and chemical risks. The physical risks can be related to humidity, heat, noise, radiations (ionizing and non-ionizing) found in the equipment constantly used in the Forensic Laboratory. The biological risks are due to the exposure to animal products and by products, vegetable and microorganisms. Among the agents of biological risks, we can cite the most important ones: bacteria, fungus, leaven, viruses, protozoan and metazoan. These agents can be present in the laboratory environment carried under several forms that offer biological risk such as aerosols, dust, food, laboratory instruments, water, cultures, biological samples, blood, urine, mucus, secretion among others. For the chemical risks we can cite alcohol, formaldehyde, glutaraldehyde, composites releasing chloride, synthetic phenol, iodous and others. We conclude that there is the need to establish more comprising norms of conduct inside forensic laboratories, mainly concerning the cOllection, handling and keeping of samples; the need of a correct understanding between the laboratory coordinator and his staff; the need to develop a correct map of risks, made in a clear, concise and evident way; and mainly the need to assign tasks to the staff, and each one will perform one task only, however they must have a general knowledge of the services to be done. It will be the responsibility of the laboratory coordinator to inspect the performance of each phase or task.
