Abstract

Objective By quantitative evaluation of acute poisoning accidents risk and occupational health risk of benzene exposure, scientific basis is provided for risk analysis and effective prediction of acute poisoning accidents and the prevention and management of serious occupational diseases such as occupational tumor in China. Methods An occupational health risk assessment on benzene is presented by in a form of case study via a large chemical enterprise styrene unit In our paper, we have been recommended to adopt the four-step method. Results Under the accident condition of benzene storage tank leakage, the lethal probability of acute poisoning is 3.49×10-12, which is lower than the acceptable risk level. 84.65% of benzene-exposed workers’ HI exceeds the safety threshold of 1, and 69.37% of benzene-exposed workers’ leukemia excess risk exceeds the acceptable risk level. The non-carcinogenic and carcinogenic risk is unacceptable, and corresponding measures should be taken to reduce the occupational health risk of workers. Conclusions It is useful to get the probability distribution of non-carcinogenic and carcinogenic risk and mathematical statistics feature by using four-step method of health risk assessment, acute accident simulation software and Monte Carlo simulation software, in order to offer more accurate information for risk managers.
