This article discusses the use of the mobile phone, which is equipped with a large number of features that help us to send textual or graphical information, shoot video or capture the world, to set various applications and surf the Internet in addressing security challenges, namely the issues of notification and management of evacuation of people. The solution to this problem is possible with the development of a dedicated app, which is one of the possible ways of improving warning systems and evacuation management. The article based on analytical data shows the level of confidence of the modern man to a mobile phone. The basis of this application, the use of a standardized method for the determination of the evacuation time. “Algorithm mobile evacuation” is as follows: when you hit a person on the territory of the object of protection and the discovery of his phone, him with such application, will be sent a message requiring you to download a plan of evacuation and action in case of an emergency. The user accepting a push notification will launch the app, which will download the evacuation plan and procedures through communication channels (GSM or Wi-Fi) to your phone. Since then, the location of the subscriber in the building will constantly be monitored. This positioning is proposed with a simple Wi-Fi network, which is available on virtually every modern facility. The principal advantages of the system of local positioning were noted: easy scalability by adding Wi-Fi access points, location detection indoors with an accuracy of 1 meter, using existing Wi-Fi networks, providing visualization of location changes in real-time, works both in open and in closed space. Also in the article the data of experiment efficiency of mobile phones in high temperatures were presented. The experiment was conducted at the base fire-training complex. The results showed that the test samples retained an important function - the ability to transfer signal that is used to determine the location of the person sufficient time.
