Desenvolvimento de vestuário de proteção aplicado à treinamentos simulados em emergências químicas

Abstract

Accidents involving dangerous chemicals are more common than we imagine, according to CETESB - Environmental Company of the State of São Paulo, in the state of São Paulo alone, 294 accidents were recorded in 2023. In the event of accidents involving dangerous chemicals, safety teams Emergency response needs to be activated to carry out operational actions such as closing pipe valves, containment and/or confinement of the spilled product. For professionals involved in chemical emergencies to be safe in their activities, they need adequate training and the use of personal protective equipment according to the level of risk in the affected environment. However, the maximum protection required, level A protective clothing, is imported equipment, manufactured with patented fabrics with high added value, which makes the acquisition of these products difficult both due to the need to import and the high cost. The purpose of this work was to develop protective clothing applied to chemical emergency simulations, facilitating the acquisition of equipment developed exclusively for training and simulations, which would make practical training more frequent in both public and private institutions. The clothing was developed in three stages, the first stage, creation, with the development of a sketch, technical drawing and technical sheet; the second stage comprised the development of modeling, grading and fitting; In the last stage, the production stage, the piece was cut, sewn and revised. The piece developed has a single layer of waterproof fabric, very heavy, with a weight of 220 g/m². The development of this work provided the production of a garment for specific use, with lower raw material costs, a technical sheet that includes the entire operational sequence of production and necessary materials, in addition to complete modeling, which allows production on an industrial scale.
