At modern enterprises with a large number of electronic equipment and polymeric designs which are located in regions with an arid and cold climate, there are serious and dangerous problems for the human - the long continuous impact of cold at the human and the accumulation of static electricity on the surface of the clothes. When the person feels sick at his workplace, there increases the probability of making a mistake which can lead to the injury or accident. That's why to protect the person and reduce the risk of his health and life at the enterprises in the conditions of cold and the high probability of accumulation of static electricity, we develop protective clothes which will allow to reduce the temperature disbalance, to increase comfortable physiological state and to reduce electrization level at the surface of the clothes.

The protective clothes with active system of thermostabilization offered by us will provide physiological comfort and safety of the person at the expense of using of Phase Change Materials (PCM) with phase transition within the thermophysiological range of body temperatures of the person [1, 3]. When developing these clothes we used the known data from the area of hygiene of clothes and considered the distribution of the temperature along the surface of the person's body on various sites and the intensity of his heat production. The thermal comfort of the person most of all depends on the body temperature. The protective clothes represent the vest covering the body of the person. The gross weight of the vest doesn't exceed 1500 g. The elements with Phase Change Materials (PCM) with the phase change of the temperature from 28 to 36 ⁰С are built-in [1,3]. The elements with Phase Change Materials (PCM) are located at the sites with the greatest thermal stream and cover the body of the human at the breast, stomach and back. Such arrangement provides the maximum thermal effect. Phase Change Materials (PCM) absorb and accumulate the surplus of the thermal energy from the human's body during his active movements or environmental temperature increase, and give back saved up warmness back at the decrease of physical activity of the person and the temperature fall. We carried out the tests of the developed protective clothes at the ambient temperature of 0°С, -10°С, -20°С . By the results of the conducted researches we should out that when using the vest the time of a comfortable condition of the person increases for 1,5-4 hours in comparison with usual clothes depending on environment conditions. Thus, the human has an opportunity not to overheat and not to overcool at the expense of use of own thermal energy for a long time.

To increase the safety of the person in conditions of production with the accumulation of static electricity, we develop protective clothes with built-in system of continuous measurement and the analysis of electrostatic intensity of the human. The supervising system consists of microsensors which are distributed at the surface of protective clothes in zones of the greatest accumulation of static electricity [2]. The developed sensor is capable to diagnose the intensity of the electrostatic field near the surface of the textile product in the course of its operation automatically. The developed sensor measures intensity of the electrostatic field which arises near the surface of the top layer of clothes, registers its value and compares it to the critical value. In case of value excess the sensor gives a sound signal of danger to the person. Such danger can be the approach of a spark which can do harm to health and human life. The sound level for such device was investigated and it was established at the level of 88 decibel. After the operation of the system, the person has to apply precautionary measures to avoid the dangerous influence.

The offered designs will allow reducing the threat of emergence of the technogenic catastrophes, to raise the level of labour, life and health protection of people which are compelled to be in adverse conditions of the environment.
