Legal Principles

Despite wide legislation basis of regulating relations in work safety and workers’ health, one third of workplaces demonstrate exceeded allowable normal levels of workers’ exposure to occupational hazards and present occupational risk for health disorders.In accordance to national legislation acts, evaluation should cover factors of occupational environment and working process, and occupational risk is understood in context of mandatory social insurance. This approach has been formed due to mostly compensatory trend in legal principles of work safety in Russia by now. Implementation of new preventive concept of work safety, based on idea of risk management for workers, necessitates development of legal acts that regulate requirements to evaluation of occupational risk and its reports with consideration of changes in Federal Law on 30 March 1999 №52 FZ “On sanitary epidemiologic well-being of population”.Those acts can include Sanitary Rules and Regulations “Evaluation of occupational risk for workers’ health”, that will contain main principles of risk assessment, requirements to risk assessment, including its characteristics which can serve as a basis of categorizing the risk levels with acceptability.To standardize requirements for informing a worker on the occupational risk, the expediency is specification of sanitary rules “Notifying a worker on occupational risk”. These rules should contain requirements: to a source of data on occupational risk level at workplace, to informational content and to ways of notifying the worker. Specification and implementation of the stated documents enable to fulfil legal requirements completely on work safety — that will provide preservation and increase of efficiency in using work resources.

Noise Measurements

Introduction. Noise is a common occupational hazard in metallurgic production. Objective. To evaluate occupational risk caused by exposure to noise in 18 occupational groups in subunits under modernization in an enterprise producing titanium alloys, using methodology of N.F. Izmerov Occupational Medicine Research Institute. Materials and methods. A priori risk evaluation by noise measurements was performed according to criteria of Manuals R 2.2.2006–05, R 2.2.1766–03 and hygienic models, a posteriori one — by analysis of occupational morbidity over 30 years, transitory disablement morbidity and chronic diseases prevalence according to medical examinations data over 5 years. Total of 58758 sick-leave certifi cates was analyzed. Comparison covered morbidity in individuals exposed to noise (3501 individuals) and non-exposed individuals (9138 ones). Results. Findings are that a risk level by hygienic criteria in the studied occupations was assigned to low to high category (work conditions classes 3.1–3.3), by occupational morbidity criterion — from low to high (index of occupational diseases from 0 to 0.25). Occupational neurosensory deafness was registered in blacksmiths, turners, vertical lathe operators. Noise appeared to be a trigger for diseases of ears, eyes, skin, locomotory system, nervous system, urinary tract, respiratory system, for mental disorders, increased blood pressure, hyperglycemia, leukocytosis, with 1.1–1.7 times reliably increased their risk in general over the production, and up to 3.7 times in certain occupations (p<0.05). Prevalence of the health disorders appeared to increase with growing noise levels. Conclusions. Industrial modernization is associated with decrease of occupational morbidity caused by exposure to noise to single cases and increase of age and length of service at noise conditions to diagnosis. Considerable health improvement was seen in blacksmiths, aft er hammer equipment was changed to the press one, in lathe operators — aft er lathe changed to processing centers with numerical control.

Risk Assessment Model

The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module. Using these tools, the symmetric position of the fuzzy sets with regard to class was used, and the symmetric fuzzy inference approach was used in an outcome calculation. The main benefit of the proposed model is being able to use numerical and linguistic data in a risk assessment model. The proposed risk assessment model, using fuzzy logic conclusions and min–max composition, was used on a mobile crushing machine. The results indicated that the risk level of the mobile crushing machine was in the “high” category, which means that it is necessary to introduce maintenance policies based on this high risk. The proposed risk assessment model is useful for any engineering system.

The article deals with the workplace safety issues in the machine-building industry taking into account the human factor influence. The significance and quantitative assessment of the human factor influence on the occupational risk level is shown. An integral criterion for assessing the human factor influence on the occupational risk level is proposed, which can be used by specialists in their work. Rating scales «Perception of information», «Decision-making» and «Actions performing» are developed for practical calculations. The empirical and weighted coefficients of the integral criterion parameters reflecting the dependence of the human factor influence on the occupational risk level are determined. A logarithmic dependence between the human factor and the occupational risk level is established

The purpose of this research is to know about working capital management applied, and its influence on profitability and risk. The research object is trading company moves in import & distribute chemical raw material. The research used analysis descriptive method, and the hypothesis was testing by simple linier regression, correlation, and determination. The result of the research shows that the effect of the implementation of working capital management on the change of the net working capital with tend to rise has a profitability level of 10.4% lower than the net working capital change with tend to go down of 46%, but instead on the risk level, the net working capital change with tend to rise has a risk level of 43.8% higher than the change in net working capital with tend to go down of 0.3%.Based on  t test, the result shows that the net working capital change influence  is not significant  to profitability and risk.
