Abstract


Epoxy materials are used in almost all areas of industry: for the impregnation of fiberglass or glass fiber in electrical engineering, electronics, automotive and aviation industries, in the manufacture of fiberglass in construction, shipbuilding and mechanical engineering, in workshops for the repair of boat hulls and car body parts, as coatings for waterproofing, as chemically resistant coatings, etc. Epoxy resin has significant advantages over similar materials: high adhesive strength, minimal shrinkage, low moisture permeability in the cured form, high resistance to abrasion, the best physical and mechanical characteristics.

The purpose of the work is to analyze the production technology of liquid epoxy resins and the harmful effects of process operations on the human body, as well as the development of measures to improve the working conditions of workers in the workplace.

When working with epoxy resins, there are two ways that harmful substances can enter the body: inhalation and skin. Inhalation is due to the presence of volatile components in the resins – epichlorohydrin and toluene, and skin – due to direct contact with volatile and non-volatile components of the resin.

Therefore, the organization of the production or technological process should provide for the accuracy of certain operations with the minimum possible use of manual labor. The processes of continuous manufacture and use of epoxy resins and materials based on them should be carried out in isolated rooms. To protect against dangerous and harmful production factors, workers engaged in the manufacture, use of epoxy resins and materials based on them, as well as the processing of products made on the basis of epoxy resin binders, are provided with personal protective equipment. These include: dressing gowns for men and women, aprons (types A, B, C, D), arm ruffles, goggles, respirators U-2K, SB-1 „Petal-200”, „Petal-40”, „Petal-5”.

As extinguishing agents, carbon dioxide and powder fire extinguishers, water, steam, inert gas, asbestos cloth, sand can be used.
