Abstract

Objective Analyze the hazards, status, and protective facilities of formaldehyde in the spraying position of a certain automobile manufacturing painting workshop in recent years, and understand the improvement measures after exceeding the standard in the spraying position. Methods Conduct occupational health on-site investigation on the spraying position in the painting workshop of automobile manufacturing enterprises, and detect formaldehyde in the air of their workplace. Results After improvement, the formaldehyde concentration in the spraying position has been decreasing year by year and finally controlled. Conclusion Formaldehyde in the spraying position of the painting workshop is prone to exceeding the standard. After screening raw and auxiliary materials, appropriately increasing the air volume of the exhaust system, and cleaning and maintaining the exhaust system, the harm of formaldehyde in the spraying position can be controlled through source control and measures to improve and clean the exhaust system. At the same time, strengthen occupational health knowledge training and education, enhance workers’ personal protection, and carry out pre employment, on-the-job, and post employment occupational health examinations.
