Evaluation of occupational disease hazard control effect for a 250 000 ton tower project of a wind energy equipment Co.,Ltd.in Yangzhou
Objective To understand the main occupational disease hazards and protective effects of the production process,equipment and facilities,as well as their corresponding supporting facilities,and in the production process,labor process,and production environment involved in the 25×104 ton tower project of a wind energy equipment Co.,Ltd.in Yangzhou.Method In October 2023,during the trial operation phase of the project,occupational health investigation method,occupational health testing method,engineering analysis method,and checklist analysis method were used to evaluate the effectiveness of occupational disease hazard control based on occupational health management situation and testing results.Result The main occupational hazards of the project were dust(welding fumes,grinding wheel dust,silicon dust,other dust),toxic substances(manganese and its compounds,nitrogen oxides,ozone,fluoride,carbon monoxide,toluene,xylene,ethylbenzene,n-butanol,zinc oxide),and physical factors(noise,ultraviolet radiation,power frequency electric field).Totally 88 workers were exposed to occupational hazards,and the remaining 45 were auxiliary workers such as interior installation,quality inspection,and warehouse management,all of whom were male.The qualified rate of dust and toxic substance detection in this project was 100％.The UV radiation and power frequency electric field damage intensity both met the standard limit requirements.Except for the three positions of polishing,sandblasting,and zinc spraying where the noise level severely exceeded the standard[95.4,89.7,and 85.5 dB(A)],all other workplaces did not exceed the standard.The side exhaust control wind speed of sandblasting,zinc spraying,and painting positions in the surface treatment workshop of the production unit cannot meet the specification requirements.The occupational disease prevention facilities,emergency rescue facilities,personal protective equipment configuration,and occupational health monitoring of the enterprise basically met the relevant regulatory requirements.Conclusion The tower project of a wind energy equipment Co.,Ltd.in Yangzhou belongs to a serious occupational disease risk project,and special attention should be paid to the polishing,sandblasting,and zinc spraying positions.It is recommended to further improve occupational disease protection facilities and emergency rescue facilities,and strengthen individual protection.
