ABSTRACT
Objective To explore the suitable risk assessment model for printing industry, we evaluated the risk of furniture industry using models provided by Singapore Ministry of Manpower (MOM) . Methods According to the occupational-disease-prevention laws and regulations, we improved the MOM and increased the risk assessment of physical agents. Then, we evaluate the risk of furniture industry using the improved MOM. Results The range of wood dust was 1.9-8.9mg/m3, and the percent of pass was 50%. The range of formaldehyde, benzene, methylbenzene and dimethylbenzene was 0.24-0.36 mg/m3, <0.6mg/m3, 3.8-6.7mg/m3 and 6.1-16.1mg/m3 respectively, and their percent of pass was 100%. Furthermore, the noise intensity was 80.8 dB (A), which was under the occupational exposure limit. The risk level of wood dust, formaldehyde, benzene and noise was high, while the risk level of methylbenzene and dimethylbenzene was moderate. Conclusion The improved semi-quantitative risk assessment was appropriate for furniture industry, but its applicability in industrial enterprise needs to be studied further.
ABSTRACT
Objective To analyze and evaluate the occupational hazards,engineering protection measures and risk levels in an oil terminal project.Methods Engineering analysis,occupational health survey,inspecting -testing and semi -qualitative semi-quantitative evaluation method (MES method)were used to analyze the production process,the type of occupational hazards,characteristics and concentrated/strong degrees and engineering protection measures of the project. Also,the occupational health risk and the effect of engineering protection were assessed.Results The main occupational hazards of this project were dust,solvent naphtha,benzene,toluene,xylene,hexane,non -methane hydrocarbons, carbon monoxide,carbon dioxide,manganese and its inorganic compounds,hydrochloric acid,hydrogen sulfide,noise, high temperature,power frequency electric field,welding electric arc and so on.Approximately,16.67%of noise samples and 66.67% of high temperature samples exceeded the Chinese National Occupational Health Standards.Except for noise of the fuel pump shed and high temperature of 100000 tons pier and fuel tank,the occupational hazards of other jobs were in line with the national occupational health standards.In normal conditions,the occupational risk levels of all positions were 5 (slightly hazardous),while in special conditions,the occupational risk level of repair welders was 5 (slightly hazardous),of pier operators and tank farm operators were 1 (extremely dangerous),of sewage treatment workers,boiler room operators and electricians were 3 (significant risk ).Conclusion This project can take effective engineering protective measures to control occupational hazards and risk management of special conditions need to be strengthened.
