Detection and Evaluation of Occupational Hazards in Machinery Company

Objective To detect and evaluate occupational hazards and occupational preventive measures on a machinery company.Methods According to related national standards,field investigation and engineering analysis were applied to identify the categories and links of occupational hazards in the production process.Results The main occupational hazard factors were toxic substance（manganese and its compound）,dust（welding fumes）and physical factor（noise）.After the field testing,C STEL and C TWA for toxic substance were 0.050-0.062 mg/m^3 and 0.019-0.023 mg/m^3,C STEL and C TWA for dust were 2.7-4.7 mg/m^3 and 2.0-3.5 mg/m^3,intensity of noise was 73.3-82.9 dB（A）.Conclusion Occupational protective measures are science and effective in the company.
