[Objective]To understand the hazard of hyaluronic acid to the workers＇ health in a biochemical workplace and make a evaluation on preventive＇ measures. [Methods]Investigation and testing on the environmental hygiene were carried out according to the national standard of GBZ 159-2004. [Results]The main hazard factors included carbinol,ethanol, sodium hydroxide, dust, noise and high temperature. The qualified rate of carbinol was 44.4 % ;The qualified rate of sodium hydroxide,dust and noise was 100. 0%. The working condition in high temperature was divided into two grades. [Conclusion]The measure for preventing and controlling occupational disease is efficient in this factory which had the necessary facilities for preventing dust, poison and noise. The overall evaluation result is up to the national standard, but the con- centration of carbinol is still beyond the limits of the national standard in some places. It must be brought under control.
