The studies and improvement of ventilation system in the paint shop

Abstract

There are many types of paint shop and different ventilation designs in the manufacturing industries. All kind of ventilation designs has their own main functions to conform to good manufacturing practices (GMP). This study focuses on manual paint shops because of its great potential for worker exposure. The design goal of industrial ventilation is to protect the worker from carbon contamination in the work place. This suggests installing a system that will reduce exposure below the permissible exposure guideline or an appropriate action level. The professional will design the system to meet this standard. The good spray shop and a good ventilation system defined in the Federal Standard 2000, as a room which the concentration of inborn particles is control to specify limits. Firstly ventilation in the spray shops finishing operation was selected for this study for several reasons. The ventilation systems in spray painting booth have been widely used to control these hazards, but no systematic study of their effectiveness had been undertaken. Secondly, the painting shop alternative coatings, where new uses technology has changed rapidly with the introduction of new material, of which represent toxic hazard. The modified ventilation, developed in the new paint line application method, promised new ways of reducing worker exposure in spray finishing operation. In this book, I shall give my best opinion how to overcome the toxically taken by the operator, through the flow of air to the environment to the filter provided. Of the ventilation noise characteristics, effects and suggested counter measures. In cost benefit analysis (CBA) the cost of remedial measure is weighed against the environmental benefits it creates, Is it worth, in a new scrubber for a plant if the impacts on its surrounding decrease by 10%. The aim of life cycle cost calculation is to ensure that investment decisions are not made solely on the basic of a low purchase price, but that the life cycle operating costs are considered in the equation. Considering the energy and maintenance cost during the life-cycle circle (LCC), the cheapest investment is not always the best. If may, for instance, be profitable to buy a ventilation unit with a heat recovery system, which may increase the unit investment by 50%. The return on the investment in such a case may still be in excess of 20%.
