Research On Employer's Occupational Hazard Risk Assessment Method

With the high development of our country's economy and the continuous improvement of industrialization,the accompanying occupational hazards are becoming more comprehensive and complicated,which seriously affects the health of workers.However,there are still many deficiencies in the prevention and control of occupational hazards in our country.it is not only necessary for employers to improve their awareness of occupational hazards prevention and control,take the initiative to do a good job in occupational hazards control,but also for occupational health supervision departments to carry out effective supervision and management.The complete evaluation system of occupational hazards can not be separated from the occupational hazards risk assessment.at the same time,the occupational hazards risk assessment is also an important part of the field of occupational hazards prevention and control,which plays a very important guiding role in the prevention and control of occupational hazards.However,our country has not yet established a systematic occupational hazard risk assessment guidelines or norms,nor has it established a risk level matching management model.The risk factors of the existing assessment methods are not considered comprehensively,and the assessment methods are too simple and do not pay attention to the health effects of the occupational disease hazard factors not exceeding limit value on workers,which still need to be improved.By comparing the occupational hazards risk assessment methods at home and abroad,this paper determines the basic methods of occupational hazard risk assessment by hazard rating and exposure rating,and its optimized,especially in the exposed part classification set of occupational hazard control level index,introduces the analytic hierarchy process(AHP),set up a more comprehensive and reasonable occupational hazard control level classification standard.On the basis of risk assessment of single occupational-disease-inductive factors,to grade the occupational hazards at all jobs.Then,the occupational hazard risk level of the employer was determined.Meanwhile,according to the assessment results of occupational hazard risk,the corresponding risk level control measures were proposed.Finally,taking an employer in fertile water as an example,combining with the actual situation of the enterprise,the occupational hazards were graded,and the grading results and suggestions were compared with the field experts' evaluation and suggestions.the results were in good agreement,which verified the rationality and feasibility of the employer's occupational hazards risk assessment method.
