Avaliação quantitativa de formaldeído em uma empresa de fabricação de painéis de MDF e MDP

Abstract

Formaldehyde is an organic gas produced worldwide in large scales, this substance is derived from methanol. It is widely used in synthetic resins, phenolic resins, urea resins and malamínicas in manufacturing processes of MDF (fiberboard of medium density), MDP panels (particle board, medium density), paper and pulp; in abrasives, plastics, synthetic enamels, paints and varnishes, textile industry and foundry, adhesives, electrical insulation, brake linings, etc.. The objective of this study is to perform a quantitative assessment of formaldehyde in a company that produces MDF and MDP, perform the comparison of the results with the standards of occupational health and safety improvements to existing point and reduced levels of formaldehyde emissions. Specimens were collected from formaldehyde vapors collections to the height of the breathing zone, with instrument attached to the employee, accompanying him on his activities in the workplace, to obtain accurate and real. The evaluation method used is in accordance with NIOSH 2016, display tube using silica gel treated with Dinitro phenylhydrazine (DNPH) and hydrochloric acid reference SKC 226-119, connected to a suction pump, collecting the vapors arising in the process. The results of the quantitative analysis showing the critical points of formaldehyde emission, for these points were mentioned suggestions for reducing emission levels.
