Lote Notes | Fire Safety & Security in Practice


Greetings again from the Lote Team! This April edition of Lote Notes will cover a variety of topics related to Fire Engineering and Security, including three pieces from our team and some other compliance updates and news articles.

The Fire Engineering team has put together two abstracts for upcoming articles: one titled 'The Use of Cavity Barriers to Mitigate External Fire Spread in Multi-Storey Buildings', and the other titled 'Probabilistic Risk Assessment of Occupant Evacuation for Office Buildings'. These abstracts (and their accompanying articles to follow in the future) reaffirm our commitment to the investigation and research of Fire Safety theory and practice, fuelled by our desire to ensure maximum human safety, design competence and cost-efficiency in all that we do.

In Security, the ISO (International Organisation for Standardization) has published a Standard for Crime Prevention Through Environmental Design (CPTED), designated ISO 22341:2021. The new Standard will enable those in the construction and planning industry to gain a basic understanding of the thought process of CPTED and the types of concerns it deals with, hopefully providing the industry a greater appreciation for the challenges and benefits of CPTED in their projects. We have written an article which takes a microscope to the Standard, listed below. We would encourage anyone in construction and planning to read through our summary and the Standard themselves to become familiar with this important aspect of development.

As usual, our work will be accompanied by relevant headlines and updates to keep you up-to-date on any new developments in these fields. We hope you enjoy this edition of Lote Notes and look forward to engaging with you on these vital topics!

Best Wishes & Stay Safe

Abstract: The Use of Cavity Barriers to Mitigate External Fire Spread in Multi-Storey Buildings

By Yahya Elhallak
Keywords: Fire Engineering, Cavity Barriers, Multi-Storey Building, Fire Blocker, Aluminium Composite Panels, Ventilated Facade





This abstract outlines a study on the effectiveness of cavity barriers in multi-story buildings. The function of a cavity barrier is to provide a fire blocker in the cavities located within the external walls of multi-story buildings, which assist to mitigate vertical fire spread.

The main goal of the research referred to by this abstract is to determine if the installation of cavity barriers is effective in stopping vertical fire spread on buildings that incorporate combustible building elements along the facade, such as aluminium composite panels (ACP) with a combustible core.

Abstract: Probabilistic Risk Assessment of Occupant Evacuation for Office Buildings

By Srinath Iyengar
Keywords: Fire Engineering, Office Evacuation, Probabilistic Assessment, Risk, Evacuation Analysis





This abstract identifies some of the benefits of conducting a probabilistic assessment of office spaces that are already compliant with the BCA, as well as outlining some shortcomings of this type of approach.

Ultimately the full paper will aim to highlight the value of combining probabilistic assessments with an evacuation analysis to more accurately determine the 'real-world' risk to life in the event of a fire, beyond simple 'yes or no' compliance with BCA Standards.

ISO 22341:2021 - Security and Resilience - the Long-Awaited CPTED Standard

By Zachariah Reisch and Dr Maher Magrabi
Keywords: Security, ISO, CPTED, Crime Prevention, Safer by Design, Capable Guardianship





The International Organisation for Standardization (ISO) has recently released a new Standard for Crime Prevention Through Environmental Design (CPTED), ISO 22341:2021 - Security and resilience - Protective security - Guidelines for crime prevention through environmental design.

While we recommend that anyone involved in development review the information within themselves, we at Lote have gone through the Standard to provide an informal summary of key ideas within, as well as our thoughts on its overall effectiveness as a representative Standard for CPTED more generally.

How Fire Engineering can keep your Building Safe

By Architecture & Design

Building fires destroy lives and property, and it's difficult for anyone to recover from one. However, with the right fire safety strategy in place, building owners can prevent such disasters. These strategies can be developed and implemented even before construction begins on a new building, or during upgrade works on old structures.

Good construction practice takes into account measures that are designed to safeguard the building when a fire does break out. Fire engineers are responsible for developing design specifications that will mitigate the overall impact during a fire.

Lessons for Australia from Grenfell Tower inquiry

By Russel Grove of The Fifth Estate

The Grenfell inquiry has brought poor choices of products to light in terms that can be easily understood by the media and the community. There are many areas of commonality between building regulation control between Australia and UK and therefore, there is every reason to believe that what is being experienced in the UK could mirror our situation.
