As the deployment of Battery Energy Storage Systems (BESS) continues to accelerate, understanding and managing the associated hazards is becoming increasingly important. One of the most significant risks associated with lithium-ion BESS is thermal runaway – a self-accelerating reaction that can lead to fire, explosion and the release of toxic gases if not effectively controlled. In this article, we explore what thermal runaway is, how it is assessed through testing and consequence modelling, and the key design and operational measures used to limit its propagation and potential impacts.

Land Use Planning for Battery Energy Storage Systems (BESS)   As the transition to renewable energy accelerates, Battery Energy Storage Systems (BESS) are playing an increasingly critical role in supporting grid stability and energy security. But with their rapid uptake comes a new set of planning considerations - particularly around how these systems are integrated into existing land uses, managed safely and assessed within evolving regulatory frameworks.    In this article, we explore the key land use planning challenges associated with BESS developments and what proponents, planners and communities need to consider to enable deployment while managing risk.

A massive congratulations to Matthew Coutts on being awarded the A.N. Hambly Prize by RMIT University for best undergraduate Chemistry student in his final year (2025). Since joining R4Risk earlier this year, Matt has brought great energy and positivity to the team. It’s fantastic to see his hard work and academic achievements recognised, and we’re very proud to have him with us.

Our team came together this morning for Australia’s Biggest Morning Tea, raising funds to support Cancer Council Australia's vital work in cancer research, prevention programs, advocacy and support services.   Thanks to the generosity of our team, we’re proud to share that we raised an incredible $1,696. A big thank you to everyone who baked, donated and supported our morning tea, and a special thank you to Amanda Roff for the effort she put in once again this year to make the event such a success.

Engaging with the next generation of risk professionals!   Last week, Matthew Coutts had the opportunity to represent R4Risk on a panel at RMIT University, speaking with 2nd and 3rd year students about graduate pathways and life beyond university. The session brought together recent graduates now working in industry, alongside current honours and final‑year students, to share real perspectives from those who were in similar positions just a few years ago. Matthew shared insights from his own journey, including: - Transitioning from a chemistry and chemical engineering degree into industry - What he found most valuable during his time at RMIT - How he approached standing out in a competitive graduate job market - Practical tips and study advice for current students It was a great opportunity to connect with students and support them as they consider their next steps.   Well done to Matthew for representing R4Risk and contributing to such a valuable discussion.

From cold storage to breweries, ammonia is used in refrigeration systems to provide efficient cooling worldwide. However, it is also highly toxic, so safety can never be an afterthought. On the night of 13 May, a large-scale release of ammonia occurred from a faulty pipe at a food processing facility in Ipswich (south-west of Brisbane). The incident resulted in the evacuation of nearly 900 workers, with five people requiring hospitalisation for further respiratory assessment following exposure to ammonia vapour. When assessing the consequences of an accidental ammonia release, one of the most widely used reference points is the Acute Exposure Guideline Levels (AEGLs). These are published by the US EPA and used internationally for emergency planning purposes and risk assessments. AEGLs define airborne concentration thresholds for short‑term exposure periods, ranging from 10 minutes to 8 hours and are designed to protect the public, including vulnerable populations. The three AEGL levels represent: AEGL‑1 – Discomfort The concentration above which people may experience eye, nose, or throat irritation, or a strong odour. Effects are transient and reversible once exposure stops — this level is about awareness, not danger. AEGL‑2 – Serious health effects or impaired escape Concentrations that may cause serious or long‑lasting health effects or impair a person’s ability to escape. AEGL‑2 is commonly used in consequence modelling and land‑use planning, as it reflects conditions where people may be unable to protect themselves without assistance. AEGL‑3 – Life‑threatening or fatal Concentrations above this level are expected to cause life‑threatening health effects or death following short‑term exposure. AEGLs are typically used for ‘worst‑case’ scenario analysis in emergency response and major hazard risk assessments. Why this matters AEGLs translate complex toxicology into clear, well-defined impact thresholds - but thresholds alone don’t manage risk. At R4Risk, we support manufacturers and users of ammonia systems by: ➡️ Identifying credible ammonia release scenarios through structured hazard studies (HAZOP, Bowtie) ➡️ Modelling toxic dispersion and consequences against specific impact criteria such as AEGL‑1, AEGL‑2, and AEGL‑3 ➡️ Interpreting modelling results to assess on‑site and off‑site impacts to people, assets, and surrounding communities ➡️ Supporting emergency planning, land‑use compatibility, and regulatory submissions with expert technical analysis ➡️ Providing our experience with the handling of hazardous materials to help demonstrate that risks are understood, controlled, and tolerable — before an incident occurs. In industries where ammonia is used, it carries severe toxic hazards if control is lost. Robust risk assessment and emergency planning aren't optional, they're essential. #ProcessSafety #Ammonia #EmergencyPlanning

Understanding how much risk reduction is needed to prevent major incidents is critical in high-hazard industries, but what does that actually look like in practice?    Our latest blog provides a clear, practical introduction to SIL (Safety Integrity Level) assessments; what they are, why they matter and how they support the design of effective safety systems.    If you’ve ever asked “How reliable does this system need to be?”, this guide breaks it down.    👉 Read more: https://lnkd.in/gyWfVzWD     #ProcessSafety #FunctionalSafety #SIL #RiskManagement

Getting bund capacity right isn’t just a compliance exercise, it’s a critical control for safety, environmental protection and operational resilience.   In our latest blog post, we unpack why usable bund capacity matters, the common calculation pitfalls we see in the field (such as displacement and interconnected tanks) and how Australian Standards should be applied in practice, not just in theory.   If you’re responsible for dangerous goods storage, spill containment or risk management, this is worth a read: 🔗 https://lnkd.in/gDxWpKSQ [r4risk.com.au]   #ProcessSafety #DangerousGoods #SecondaryContainment #RiskManagement
