Simulating Hospital Evacuation
PRESENTED BY Aoife Hunt, Ph.D., BSc (Hons), FHEA, MLMS, Consultant, Urban Space, Transportation, AECOM
Evacuation of those with severe movement impairments can be highly problematic in hospitals – for the patients, for the staff and for the other evacuees. It is critical to understand the performance of horizontal and vertical evacuation strategies, including the means by which people with reduced mobility (PRM) can be assisted in stair descent. This presentation describes work undertaken to quantify the performance of trained hospital staff in evacuating PRM and specifies algorithms to explicitly represent the dynamics of these devices within evacuation models. Data are presented from 32 trials where test subjects were evacuated through 11 floors of Ghent University Hospital using four commonly used movement assistance devices: stretcher, carry chair, evacuation chair and rescue sheet. The performance results form the basis of integrating movement devices into the buildingEXODUS model to calculate the movement of devices along corridors, through doorways and in stairway descent. These developments address the key evacuation components of repeated patient collection, and have numerous applications, both in simulating hospital evacuation and in representing evacuation of other premises that include PRM. This new functionality can be used to significantly enhance planning and diagnostic capabilities related to the evacuation of hospital and other healthcare facilities.The link to register is available here.

Understanding Commissioning and System Acceptance Testing
Presented by Jack Poole, P.E., FSFPE, Principal, Poole Fire Protection
This presentation will explain the differences between Acceptance Testing, System Commissioning and Integrated System Testing as it relates to fire protection and life safety systems. The presentation will explain how Commissioning is accomplished, the process for which it shall be performed and the documentation and training that should be provided as part of the overall process. The presentation with emphasize that Commissioning is a systematic process, which starts at the design phase of a project and continues through the construction and testing phases of the project to ensure that all fire protection and life safety systems and components function as required per the design criteria. The presentation will define the Commissioning Team and the importance of the Fire Commissioning Agent and discuss the documentation that should be provided as part of the overall process for Commissioning, Acceptance Testing and Integrated System Testing.The link to register is available here.

SFPE Performance-Based Design: Underground Car Park
PRESENTED BY Kristin Steranka, Fire Protection Engineer, Koffel Associates and Lauren Schrumpf, EIT, Fire Protection Engineer, Koffel Associates
The Society of Fire Protection Engineers (SFPE) provided three case study specifications from which teams around the world could choose to prepare a performance-based fire safety strategy. Each case study specified performance objectives, a basic building description, floor plans, and minimum project requirements. Koffel Associates, Inc. chose to prepare Case Study 1-Underground Car Park and made additional assumptions to complete the performance-based design analysis.
The study was completed in accordance with the International Code Council Performance Code for Buildings and Facilities, 2015 Edition. The Society of Fire Protection Engineers: Engineering Guide to Performance-Based Fire Protection, 2007 Edition served as a template for the design and reporting of the project. Two design fires were developed and analyzed using Fire Dynamic Simulator and egress calculations to determine if life safety was preserved. For each design fire, two trial fire safety designs were evaluated: with automatic sprinkler protection and without automatic sprinkler protection. A prescriptive code deficiency required the use of this analysis to ensure that adequate egress time was provided to occupants within the garage. The performance-based design developed an adequate level of life safety deemed acceptable by the stakeholders without imposing unnecessary constrains on other aspects of the building design.The link to register is available here.

A Study of Reproducibility of a Full-Scale Multi-Room Compartment Fire Experiment
PRESENTED BY Nils Johansson, Ph.D., Associate Senior Lecturer, Lund University
A study of 45 full-scale compartment fire tests will be presented. All tests were conducted in the same experimental setup but with four different ventilation scenarios. The experimental setup consisted of a three-room compartment connected to a stairway. The tests were conducted during a six-year period under slightly different ambient conditions. The purpose of the study was to quantify the reproducibility of these tests with the aim to illustrate the degree of variability that can be expected in this type of experiment and how the variability is affected by different ventilation scenarios.
The 95% confidence interval of the measured temperature rise in the tests covered ±7-35% around the mean, depending on place of measurement and studied scenario. The variation in the results is due to both the variation of different weather conditions and other unknown parameters. It has not been possible to statistically distinguish between these two sources of variation in this work. The variation gives an estimate of the random error that can be expected in this type of experiment, which is something that is considered important for fire engineers to keep in mind when analyzing or referring to fire tests.

Modeling Gas Release from Lithium-Ion Batteries during Thermal Runaway Using FDS
PRESENTED BY Gerard Back (Jerry), CFEI, CVFI, Senior Fire Protection Engineer, Jensen Hughes
The results of an extensive full-scale lithium-ion battery thermal runaway tests series was used to generate input data for the Fire Dynamics Simulator (FDS) model, and to calibrate and verify the accuracy of the model predictions. The FDS model was found to be able to accurately predict the internal temperature rise as well as the external skin temperature of the Unmanned Underwater Vehicle (UUV) caused by the hot gas released during a thermal runaway reaction. Additionally, the FDS model predicted that the adjacent battery modules inside the UUV would not reach thermal runaway, agreeing with the test results.
Using the predictive abilities of the FDS model, additional battery configurations were evaluated to determine the level of fire hazard. Due to the high cost of the batteries and the UUV hardware it was not possible to perform these tests at full scale, but the FDS model simulations provide insight into the extent of the thermal runaway reactions in larger battery configurations. FDS was also used to assess the effectiveness and optimize the design of different ventilation system configurations installed in the UUV storage/shipping container.
