Control Effect of Occupational Hazards in Construction Project of Hydrazine Hydrate

Objective To investigate,analyze and evaluate the occupational risk factors in the construction project of hydrazine hydrate. Methods Based on the national occupational standards ,field hygiene investigation,occupational risk factors monitoring and occupational health examination were carried out. Results The items including the selection of site,the arrangement and layout of the facilities,occupational disease prevention and protection measures ,and individual preventive articles met the requirements of national standards. Risk factors included Cl2,NH3,NaOH,HCl,acetone,hydrazine hydrate,noise and power frequency electric field. The concentrations （ intensities） of risk factors in all posts were in accord with the national standards,the main toxic hydrazine hydrate was below 0.05 mg/m^3. Conclusion It is basically effective for the construction project to take preventive measures,emergency management should be strengthened,and warning logo would be posted.
