Labour activity of people in industrial enterprises refers to such types of work where a distinctive feature is the constant collision with danger. The activities of people actively used flammable, explosive, toxic and radioactive substances. The use of sophisticated and efficient equipment, as well as modern technological processes accompanied by an increase in the number and increase the level of negative factors working environment. With the increased levels of negative factors in people having chronic and acute diseases and occurs in injury and loss of life. Safety - is the level of protective measures and means of providing real risk reduction to an acceptable risk when negative factors do not exceed the permissible value. The issues of industrial safety in industrial plants - one of the most important tasks of human society at the present stage of development. This problem arises especially in the present stage of development of the productive forces, when, due to difficult to predict the social, technological and environmental consequences of emergency situations there is a risk of human society. The decision of health and safety problems in industrial plants is impossible without the creation of normal conditions for human activities. For the implementation of protective measures and means are currently used various security systems. The authors consider ways of ensuring safety in industrial plants. The authors argue that to check the parameters of working conditions and control degrees of factors of production environment, you can use the device that is related to the field of control parameters of working conditions, and can be used to control the levels of the factors of production environment, entitled Device control parameters of working conditions. This method of control parameters of working conditions allows you to control the actual levels of factors of working conditions, such as temperature, noise, illumination, electric field intensity in the working areas of industrial enterprises. The article focused on a wide range of readers interested in this issue.
