SELECTION SYSTEM OF WARNING AND EVACUATION CONTROL DURING A FIRE

The current paper demonstrates that the evacuation in case of the fire is an organized process of moving from the danger zone to a safe area and that it is often the only way of rescue. The warning system and evacuation management (WSEM) is a set of organizational measures and technical equipment designed to promptly inform people about the fire and necessary escape routes. As practice shows, the lack of effectiveness of these systems leads to human casualties and massive financial losses. The present research considers different types of WSEM and provides comparison between the domestic and foreign equipment, comparison of systems by their installation time, comparison between wired and wireless systems. The features of the wireless alarm systems as well as application of digital technologies are considered in the paper. The main advantage of the wireless WSEM is reduction in effort and hence the lesser cost of system-building as compared with the wired systems. Thereby, the wireless technology may eventually take a significant share in a warning system market. The same goes for digital WSEM using LAN
WAN data transmission channels. However, the application of these systems is limited by the fact that they are not covered by the existing regulations. The paper analyzes various equipment for such systems, the effectiveness of their investing, and persistence of the WSEM against the fire. At the end, conclusions about effectiveness and appropriateness of the various types of equipment for the WSEM are made.
