A smart system for evacuation and rescue support in case of a large building disaster and an operation method for the smart system are disclosed. In an embodiment, a smart system deployed in a large building includes: a communication part that, in the event of an emergency situation, receives information on an emergency situation from an integrated control center of the large building; a sensing part including at least one camera; an output part that outputs information; a driving part that moves the smart system; a boarding part for getting a user in the large building aboard; and a control part that controls the communication part, the sensing part, the output part, and the driving part, wherein the control part determines crowdedness by analyzing an image inputted through the at least one camera, operates in a kiosk mode and outputs information through the output part, if the crowdedness is equal to or above a preset threshold, operates in a rescue mode and moves the smart system through the driving part, if the crowdedness is below the preset threshold, and searches for a mobility handicapped person or a person in need of rescue by analyzing an image inputted through the at least one camera.

A respiratory and eye protection device having at least one filter and at least one axial fan. The least one filter is configured to achieve an aerosolized particle contamination filtration efficiency of 50% or greater for particles having a size of about 0.3 m and configured to achieve a vapor contamination filtration efficiency of 50% or greater for one or more of Novichok nerve agent (A232), thickened venomous nerve agent (TVX), sulfur mustard agent (HD), thickened sulfur mustard agent (THD), soman nerve agent (GD), and sarin nerve agent (GB). During the operation and monitoring of the respiratory and eye protection device, at least one fan is activated when concentrations of select aerosolized chemical, biological, radiological, and nuclear (CBRN) agents are detected.
