Gerenciamento de produtos químicos e uso de equipamentos de proteção individual e coletiva em laboratório na área de microbiologia, da Universidade Federal de Uberlândia

Abstract

Chemicals are substances that can cause harm to health and damage to the environment and require special attention since each one behaves differently, needing to be treated individually. This work had as main objective to propose chemical products management for the Laboratório de Microbiologia Molecular (MicroMol)/ICBIM/UFU, as well as to analyze and guide on the correct use of Personal Protective Equipment (PPE), make available and disseminate information about fires. In MicroMol 99 chemical products were present, and in order to obtain information about their handling, storage, correct disposal, and other aspects, the Ficha de Segurança de Produtos Químicos/Material Safety Data Sheet/Safety Data Sheet was used, and then summaries of this material were made. Considering the Hazard Diagram, over 50% of chemicals are considered hazardous to health. According to the Globally Harmonized System of Classification and Labeling of Chemicals, less than 50% are irritants. Regarding Personal Protective Equipment, it was observed that gloves were recommended for almost half of the chemicals, being the most indicated in MicroMol, the nitrilic one. An interesting fact is that almost all chemicals require the use of protective eyewear for handling. The recommended EPCs are autoclave, biological safety cabinet, shower, eye-wash and fire extinguishers. Regarding fire fighting, we conclude that the most appropriate extinguishers for MicroMol are classes A, B and C, and the extinguishing agents are chemical powder and water. This is because chemicals, equipment and other materials such as paper and wood are present in the laboratory. It can be concluded that the proposal of chemicals management for MicroMol/UFU is fundamental, because it allows users to know better the chemicals worked and thus adopt measures to manage them properly.
