Abstract Objective To understand the occupational hazard factors in the production process and preventive measures in a soda ash plant, provide the basis for prevention and treatment of occupational diseases. Methods On-site occupational health investigation and detection of occupational hazards in the workplace were adopted to perform investigation and analysis on current status of occupational health. Results The main occupational hazard factors in the factory included dust, ammonia, sodium carbonate, carbon monoxide, hydrogen chloride, hydrogen sulfide, noise, high temperature. The exceeded rates were 21.2% for dust, 14.9% for ammonia, 13.8% for sodium carbonate, and 11.8% for noise. Hydrogen chloride, hydrogen sulfide and high temperature were up to the national health standards. Conclusion The protective measures and facilities of occupational hazards of this plant are feasible. The occupational health management system is relatively complete. But the indicators of some occupational hazard factors are high in this factory. It is necessary to improve the working environment, increase the protection degree and control the density and intensity of occupational hazard factors to prevent occupational disease.
