Dur- ing the assessment of the turning lathe position additional components associated with the jobs per- sonalization were taken into account. Paragraph 2 item 7 of the Regulation of the Minister of Laborr and Social Policy of 26 September 1997 on general safety regulations defines occupational risk as the likelihood of an adverse event. The authors drew attention to the reality of the accident, which sometimes depends on the predisposition of the employee. It turns out that a correct estimation of the probability of occurrence of the accident to be able to react in a timely way seems extremely im- portant.. This parameter will be assessed more accurately if we take into account a number of addi- tional components resulting from the characteristics of the employee. The results of the personalized assessment of risk may allow appropriate planning of corrective and preventive actions.

Introduction The provisions of the Labor Code in the art. 226 indicate a series of tasks and responsibilities of the employer related to risk at work occurring at the workplace, which is the basis of preventive health protection of workers. A duty to assess, document, inform employees of the occupational risks and the rules of protection against threats, and above all the need for the necessary preventive measures to reduce the risk are worth specifying. However, to be able to introduce appropri- ate corrective or preventive measures, it is necessary to esti- mate this risk as precisely as possible. Due to the lack of specific guidelines on the assessment of occupational risk, it is conducted in various ways, depending on the knowledge and experience of evaluators. The choice of the appropriate method is not successful in the assessment. It is crucial to estimate accurately various parameters of the method used which, in consequence, leads to the real result of the final risk assessment. As a result, there is a possibility of preventing or minimizing the effects of adverse events. 2. Estimation of professional risk The risk assessment includes collection of information, hazard identification, risk assessment and determination of risk acceptability. Estimation of occupational risk is, there- fore, the third step in the whole procedure of the assessment. The selection of an appropriate method that will be adequate to the analyzed position is important at this stage, and then one needs to determine the size of the individual parameters, while taking into account all information gathered so far. The position evaluated. Parameter P is very important in the risk assessment pa- rameter is P defined as the probability. It is found in most of the available methods, e.g. PN-N-18002, PHA, Risc Score, or IEC 300-3-9 (GREENWOOD R. 2006, ROUGHTON J., CRUTCHFIELD N. 2008) 3. Additional components and their impact on the probability parameter Probability means assigning numbers to the random events, usually from the unit range indicating the chances of occurrence (ZAŁUSKI W. 2008, CONSTANTIN S. 2012). In practice, the bases for assigning the appropriate quantity to the probability parameter during the occupational risk assessment are the data on accidents, occupational diseases, or information gained from observation on the posts and an interview with the employee. However, in the literature (ORDYSIŃSKI S. 2014, WOŹNY A., PACANA A. 2013,
