Abstract

Risk of fire and smoke dangers are greater in high-rise rather than low-rise buildings. Use of high expansion foam delivered through elevator shafts can prevent or reduce smoke and fire damage and injury in high-rise buildings. Injection of foam with high multiplicity due to structural rigidity can accumulate between floors of buildings to prevent the spread of flame and smoke. Reaching an area of high-intensity flame, this foam is destroyed, resulting in the absorption of energy from the upward flow of products of combustion.

Highlights

Generating mesh in the form of truncated pyramidal surfaces are arranged so that their vertices lie on an axis coinciding with the axis of the housing, the vertex direction of the outer 15 and inner 14 coincides generating grids, and the intermediate vertex 11 mesh hydrochloric generating oppositely directed vertices outer 15 and inner 14 generating meshes with foam solution towards the distributor
Given that the height of the foam column can reach several meters, it is necessary to select foaming agents that are able to form a foam with a high capillary pressure limit
An increase in the height of the foam layer leads to a synchronous increase in hydrostatic and capillary pressure in the foam channels and the rupture of foam films

Summary

Introduction

A high- Risk and danger of fire and smoke in high-rise buildings. High-rise buildings are exposed to many dangers, but one of the highest dangers possible is fire. Existing statistics about fire emergencies in high-rise buildings confirm this level and kind of danger [1,2,3,4,5]. Fires in high-rise buildings especially are dangerous because, unlike in low-rise buildings, evacuation is quite difficult and fire control is complex. Fires in high-rise buildings feature rapid vertical development and require elaborate evacuation and rescue schemes. Tragic consequences can result from fires in high-rise buildings when fire and the products of combustion block human escape routes
