ترجمه مقاله اهمیت ایمنی و سلامت

The intent of the paper is to provide a very brief summary of potential safety and health concerns/hazards associated with the coatings industry for inclusion in this publication. This paper is far from a detailed, thorough assessment of any and all hazards associated with the practices of this industry. Extremely simplified, the application of a coating involves the removal of any previous coatings/paints, followed by surface preparation, and subsequently, the application of new coating. Removal of old coatings and surface preparation is usually accomplished via water blasting, steam blasting or abrasive blasting. This process often creates a large debris cloud of both blasting media and removed product. The application of a coating involves either spraying or brushing the material onto the prepared surface. This frequently results in an atmosphere with high concentrations of aerosolized coating material. Most coatings, paints, and protective agents are comprised of a long list of materials, many of which have properties that make them potentially harmful to human health. Ingredients will likely include some type of solvent (aromatic and aliphatic hydrocarbons) mixed with pigments and additives. The additives may include organo-mercury compounds, copper oxide, arsenic, organo-tin compounds, cadmium, chromium, lead, zinc chloride, and others. The process of surface preparation and application of the coating, coupled with the potentially hazardous materials used in the coating, create occupational health risks that could cause both acute and chronic illnesses to workers.
