Abstract: Objective To understand the occupational health risks and protection status of small cement production enterprises in Xinjiang,and to provide basis for improving the occupational health work in Xinjiang cement industry. Methods In December 2021,a small cement production enterprise in Xinjiang was taken as the investigation object,and the occupational hazard exposure level of 14 occupational health risk factors and 13 key positions were detected and evaluated on the spot,and the occupational protection measures and personal protective equipment of the enterprise were investigated. Combined with the relevant occupational health standards,the occupational health status of the enterprise was comprehensively evaluated. Results The main occupational hazards in a cement production enterprise in Xinjiang were noise,high temperature,power frequency electric field,silica dust,limestone dust,gypsum dust,coal dust,cement dust,carbon monoxide,nitrogen dioxide and sulfur dioxide. There were 80 detection points for occupational hazard factors,of which 79 were qualified and 1 noise detection point was unqualified,with an overall qualified rate of 98.7%. The noise difference of each evaluation unit was statistically significant（F=7.63, P<0.01）,the noise of clinker burning unit[90.84 dB（A）] was significantly higher than that of other units,and the noise of central control building[51.65 dB（A）] was significantly lower than that of other units. The difference of contact dust concentration in different sections was statistically significant（F=14.73 P<0.01）. The contact dust concentration in crushing section（6.93 mg/m³） was significantly higher than that in milling section（1.18 mg/m³） and packaging section（1.39 mg/m³）,and the total dust and breathing dust in crushing section were higher than those in other two sections. Conclusion Noise and dust are the main occupational hazards in small cement production enterprises in Xinjiang,and the protective measures of enterprises have obvious control effect on dust,so the production equipment should be further improved to reduce noise.
