Manual de Segurança Química para o Laboratório de Papiloscopia Forense do Instituto de Identificação Félix Pacheco: elaboração de referencial para a Secretaria de Estado de Polícia Civil

Abstract

Fingerprints have characteristics that make them unique. No finger or person has the same fingerprint pattern, a condition that also applies to identical twins. Another remarkable feature of fingerprints is their immutability, and this set of peculiarities allows them to be used for human identification. The work of the Instituto de Identificação Félix Pacheco (IIFP) in crime scene fingerprint examinations has been intensifying and has proven relevant in the fight against crime. In crime scene investigations, almost exclusively regular fingerprint powders are used, which limits the analysis to smooth and dry surfaces. The materials received by the IIFP's Forensic Fingerprint Laboratory, on the other hand, are varied in nature and treated with more specific reagents depending on the type of surface. Among the most commonly used reagents are ninhydrin, cyanoacrylate, and basic yellow. Despite performing analyses typical of a chemical laboratory, the IIFP's forensic fingerprint laboratory does not have a detailed document outlining the procedures and laboratory conditions to ensure the safety of the staff working there and the quality of the results. Therefore, the need arose to create a specific chemical safety for the service. The work began with mapping the routine of the fingerprint laboratory, followed by a risk analysis of the mapped activities. With the activities and risks identified, research was conducted to develop standard operating procedures (SOP), work instructions (WI), and a chemical safety manual specific to the IIFP's forensic fingerprint laboratory. In the end, two risk maps, two SOPs, eight WIs, and a Chemical Safety Manual were created. The biosafety manual aims to serve as a reference for the adaptation of various work bases spread throughout the State of Rio de Janeiro that are conducting or intend to conduct work similar to that performed at the IIFP.
