Application of fuzzy mathematical model in health risk assessment of occupational hazards in high-temperature refractory shed board manufacturing enterprises

Objective The application of fuzzy mathematical model in the health risk assessment of occupational hazards in high-temperature refractory shed board manufacturing enterprises was discussed, and the occupational hazard level was comprehensively evaluated.

Methods Occupational health investigation was done in this manufacture to identify and measure occupational hazards. The operational fuzzy theory was used to construct a mathematical evaluation model to assess the occupational hazard risk at workplaces.

Results The workplaces in this company were divided into three production areas, namely raw material processing, product manufacturing, and auxiliary production. The maximum membership values of each production area were 0.463, 0.567, and 0.910 and the corresponding occupational hazard risk levels were Ⅲ (acceptable), Ⅱ(Good)and Ⅱ(good), respectively. The maximum membership value of whole enterprise was 0.549 and the occupational risk was ranked as Ⅱ(good).

Conclusion The fuzzy mathematical model can be applied to assess occupational hazard risk levels in this high-temperature refractory shed board manufacturing enterprises, and provides a basis for comprehensive evaluation of the overall and/or specific occupational hazard risk in these enterprises.
