The purpose of the article is to develop a probabilistic method for assessing the impact of EMF energy on electrical personnel. To achieve this goal, it is necessary to solve the following tasks: 1. Determine which harmful production factors affect electrical personnel. 2. To investigate the EMF energy parameters affecting personnel: the average shift energy load, the dose of potential irradiation energy and the specific daily dose of absorbed EMF energy. 3. To build a model of events of harmful effects of EMF energy on electrical personnel. Due to the lack of methods for probabilistic assessment of the impact of electromagnetic field parameters (EMF) on personnel, the article proposes a method of logical-probabilistic modeling that allows to estimate the conditional probability of harmful effects on personnel: the average energy load, the dose of potential irradiation energy and specific daily doses of absorbed EMF energy. The method of logical-probabilistic modeling is used to describe random processes associated with the impact of EMF parameters on electrical personnel. The mathematical essence of modeling is the use of logic algebra functions to analytically record the harmful effects of EMF parameters on personnel and to develop ways to transition from logic algebra functions to probabilistic functions that objectively reflect the degree of harmful influence. Using the available data, the conditional probability of the occurrence of staff diseases from EMF is estimated. A possible scenario for the
