There was performed an analysis of the working conditions and health status of workers of the chemical enterprise. In male electrical staff exposed to electromagnetic fields (EMF) of 50 Hz and chemicals, according to data of periodic medical examinations there was revealed statistically higher incidence of cardiovascular diseases and autonomic disorders. The obtained preliminary results allow to suggest the upsurge of the involvement of the autonomic nervous system in response to the combined effects of EMF of 50 Hz and chemicals.

Features of working conditions and a state of health of operation personnel of the network companies of power industry were studied for the purpose of justification and introduction of preventive actions for the decrease in influence of factors of professional risk.

Having assessed functional state during the work, the authors revealed factors proving stress state in operative staffers of electric power stations. Features of occupational activities and workplace organization were assessed, risk factors promoting stress states were revealed, recommendations on optimizing the working process and on health preservation were specified.

The authors first revealed reliable decrease in general capacity and amplitude of electromagnetic waves in staffers subjected to occupational electromagnetic fields of 50 Hz--that proves increased risk of cardiovascular diseases dependent on vegetative matters. Present norms on electric and magnetic fields of 50 Hz should be justified and intensified.
