1. 1. Modellering av utrymningshissar som utrymningsväg från djupa undermarksanläggningar

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Oscar Mårtensson; Anna-Lena Johansson; [2022]
   Nyckelord :Evacuation; egress; elevator; underground; building; evacuation elevator; emergency elevator; ascending evacuation; stairs; model; occupant evacuation elevator; OEE; exit choice; human behaviour; Technology and Engineering;

   Sammanfattning : Elevators could be an important alternative means of egress when it comes to evacuation. This report is the result of a model developed to calculate the efficiency of elevator evacuation in different scenarios in deep underground facilities. LÄS MER

3. 2. Mescape - A probabilistic mesoscopic model for fire evacuation in large gatherings

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Lorenzo Contini; [2022]
   Nyckelord :Human behaviour; crowd evacuation; mesoscopic modelling; hydraulic model; large gatherings; fire safety; performance-based design; quantitative risk assessment; consequence analysis; uncertainty analysis; probabilistic modelling; Technology and Engineering;

   Sammanfattning : This study presents a mesoscopic model that predicts pedestrian evacuation in large gatherings with probabilistic methods. The model is based on a coarse network representation of buildings, where occupants are treated at a different scale according to their location. LÄS MER

4. 3. Factors influencing the generation of carbon monoxide in fires partially suppressed through water mist application

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Haydn Lewis; [2020]
   Nyckelord :Fire safety engineering; water mist; fire suppression; carbon monoxide; water; combustion; Technology and Engineering;

   Sammanfattning : Fires in the built environment typically consist of diffusion flames with inefficient mixing of fuel and oxygen, resulting in a degree of incomplete combustion and the generation of carbon monoxide. Fire suppression systems, used to control the growth and spread of fire, influence the combustion reaction process. LÄS MER

5. 4. Fire Risk and Vulnerability in Urban Informal Settlements in Metro Manila

   Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Författare :Darlene Rini; [2018]
   Nyckelord :Urban fire risks; informal settlement fires; urban fire risk management; GIS; URDI; urban disasters; risk indexing; fire statistics; Metro Manila; Quezon City; Science General;

   Sammanfattning : Urban fires, particularly in informal settlements in rapidly urbanizing cities in the developing world, are an “everyday disaster” that oftentimes goes unnoticed or under-served in the face of disturbances of the more “lethal reputation”. These disturbances of normal existence are arguably the most debilitating to vulnerable communities and sustainable development, and yet get little attention in disaster literature or in practice.

7. 5. A Novel Way of Measuring Inter-Person Distance: A Study Involving an Ultrasonic Measurement Device

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Selenay Simsek; [2016]
   Nyckelord :Pedestrian movement; evacuation experiments; inter-person distance; fundamental diagram; Technology and Engineering;

   Sammanfattning : A Novel Way of Measuring Inter-Person Distance: A Study Involving an Ultrasonic Measurement Device The quantitative characteristics of people movement that form the fundamental diagram have an important role in the field of Fire Safety Engineering regarding evacuation. The fundamental diagram indicates the relation between crowd speed and crowd density (or inter-person distance) or flow of crowd and crowd density. LÄS MER
