Nowadays there are more than 170 enterprises working in electrical and electronics industry in Latvia. Ongoing expansion and increasing of production at the enterprises of Latvian electronic industry simultaneously increases the risk of harmful chemical exposure on employees of these enterprises, because of the volume and intensity of the use of health harmful chemicals increases. The aim of the article is to analyze the chemical safety of employees in the electronic industry enterprises. The analysis of the production process of electronic products has been done. It is noted that the basic chemical safety is associated with the processes of soldering electronic components. An analysis of the impact of production volumes on the concentration of harmful substances in the working area was done by the example of one of Latvian electronics industry enterprises. It is noted that the main measure eliminating the harmful effects of lead vapors is the ventilation system. The authors performed the calculation of the concentration of lead vapors in the work area taking into account the increasing production and defined the requirements for the ventilation system.
