Risk assessment can provide the technology measurement to decrease the accident. China has issued two national occupational health standard- ‘Classification of occupational hazards at workplaces’ (GBZ/T229–2010) and’ Classification for hazards of occupational exposure to toxicant’ (GBZ/T230–2010) in 2010. According to the toxicant exposure standard, calculating the hazards level, exposure to toxicant and labour intensity of workers can assess the exposure risk of workers. This study investigates and assesses the occupational disease hazard factor in the Hovercraft manufacturing enterprise.Method
To adopt the occupational health investigation method, detection and testing method and risk assessment method to measure and analyses the concentration or intensity of occupational hazards in workplace, and develop the qualitative and quantitative analysis according to the national occupational health standard- ‘classification of occupational hazards at workplaces’ and ‘classification for hazards of occupational exposure to toxicant’.Results
On the basis of Chinese national standard ‘Specifications of air sampling for hazardous substances monitoring in the workplace’, concentration of ten occupational hazards factors which are Fibrous glass dust, Welding fume, Styrene, Acetone, Ozone, Carbon monoxide, Nitrogen dioxide, Sulfur dioxide, Epichlorohydrin, Manganese are detected under the national standard. The highest toxicant hazards index of Sulfur dioxide and Epichlorohydrin is 59, and the lowest toxicant hazards index of Nitrogen dioxide is 40 in the 10 occupational hazards of this factory.Conclusion
There are higher occupational hazards risk in glueinggluing post of Boat manufacturing. The hazard level of styrene and epichlorohydrin is highest in the 10 occupational hazards.
