Tuition system for the management of biological hazards

Dr.C.N.Zaharia—The Romanian National Research Virusology Institute Ph.D.Stefan Kovacs-The Romanian National Research Institute for Occupational Safety
Risk prevention is one of the main objectives connected with the assurance of proper work conditions at the workplace and also with the health and safety preservation. Risk action determines occupational accidents and professional diseases- with thousands of causalities across Europe, each year. In this respect, risk prevention is one of the main duties of every manager, regardless of the type of enterprise or personnel number. Biological hazards, due to their specific action, are one of the main problems in safety assurance. Action of biological hazards, if not contained properly, could cause major damage to human life and safety and also to the environment. Their specificity implies special prevention activities-allocation of big amounts of money and other resources in order to prevent the spreading of biological agents into environment. „T…

Applications of finite element methods into risk assessment

The paper presents a new approach in risk analysis, using the finite element concepts in order to improve and optimise this analysis. The focus of risk analysis on a finite element of the work place( where all the risk elements could be found) will allow a quantitative representation of risk action, taking into account all the four elements of the man-machine system (human operator, task, machine and work environment) and will contribute to a better understanding of specific risk actions.It will also lead towards a global risk image  at the enterprise level, in order to have the optimum data to develop efficient prevention plans.Formalisation equations are shown in the paper. An orientative Finite Risk Element schema is shown in the figure 1.

The risk interactions between the elements of man machine system could be expressed considering an observer in a specific observation point (human operator, task, machine, work environment) and following the other element…
