Investigation and analysis of occupational disease hazard factors of a precision tool manufacturing enterprise in Shaanxi Province

Abstract

In order to test and analyze the occupational disease hazard factors of a precision tool manufacturing enterprise in Shaanxi Province, and provide protective measures for protecting the health of workers. We tested and analyzed the occupational disease hazard factors of the precision tool manufacturing enterprise in Shaanxi Province by occupational health field investigation method and detection method in August 2022. Resultly, the main occupational disease hazard factors in the enterprise are dust and noise, and the timeweighted average concentration of dust contact point is less than 0.3 mg / m 3 , meet the requirements of occupational contact limit; There are 21 noise working points, the equivalent sound level strength of fitter in fitter area is 86.1dB (A), exceeding the occupational contact limit, and the other noise points meet the requirements of occupational contact limit. Thus, the noise in the workplace exceeds the standard, so it is recommended to take reasonable protective measures.
