As the use of lithium-ion batteries on construction sites increases, so does the need for effective fire safety measures to handle the unique challenges they present. Here, Daniel Robins, projects director at CheckFire, explores the increasing risk of lithium-ion battery fires and the appropriate safety measures construction managers need to take to ensure property and lives are protected. With the proliferation of lithium-ion batteries in modern devices, the risk of fire incidents has become a pressing concern. This type of battery can power everything from smartphones and laptops to electric vehicles, and industrial equipment – including that found on construction sites, where rechargeable electric devices are commonly used and stored.In the UK, fire services responded to 46% more fires linked to lithium-ion batteries in 2023 compared to 2022. This surge underscores the urgency for construction sites to be adequately prepared to address these fires. As set out in the Regulatory Reform (Fire Safety) Order 2005 (RRFSO), all responsible person(s) have a legal duty to provide and maintain satisfactory fire precautions – including the consideration of lithium-ion batteries in all fire risk assessments. Lithium-ion battery fires are typically caused by thermal runaway and catastrophic battery failure. Overcharging, overheating, physical damage, or internal malfunctions can all trigger these dangerous events. Once a battery ignites, the fire rapidly propagates across all the cells and results in explosion, causing significant property damage and posing serious risks to lives. To mitigate these risks, construction managers must implement robust fire safety protocols tailored to the unique nature of lithium-ion battery fires. Implementing fire safety measures First and foremost, staying up-to-date with the latest safety standards and regulations is essential. Construction managers should engage with fire safety experts to continually refine their protocols and ensure compliance with legal requirements. This proactive approach can help prevent incidents and minimise the impact of any fires that do occur. There are an endless number of fire risks that could present on construction sites depending on what and where the project is. Regulation 29 of the Construction (Design and Management) Regulations 2015 (CDM) states: Suitable and sufficient steps must be taken to prevent, so far as is reasonably practicable, the risk of injury to a person during the carrying out of construction work arising from – (a) fire or explosion; (b) flooding; or (c) any substance liable to cause asphyxiation. This requires the principal contractor to set reasonable safety measures to avoid the harm of those working onsite. For example, flammable materials should not be stored near an ignition source, appropriate fire extinguishers must be clearly visible and accessible, and high-risk tasks should be performed by a qualified person. Each class of fire has to be tackled by a fire extinguisher specifically designed to address its unique causes and characteristics. Alongside putting out the flames, a lithium-ion battery fire extinguisher should be endothermic, drawing out the heat from the battery in order to halt thermal runaway in its infancy, preventing other cells from heating and exploding. This type of fire extinguisher should also boast high Class A ratings to help protect from any secondary fires that could be caused by the exploding battery. Collaborating with local fire services Finally, working closely with local fire services is crucial, as they can provide valuable insights and assistance in developing effective fire safety strategies. Regular consultations and drills can help ensure construction teams are prepared to respond swiftly and effectively in the event of a fire. And – as with any other setting – users of the area must all be made aware of plans and tasks should a fire break out. Everyone should be clear on escape routes, fire exits and assembly points. Emergency signage is crucial in helping people off the site and directing them to safety, and site workers should be aware of the location of fire extinguishers to aid their escape. The increasing use of lithium-ion batteries on construction sites necessitates a proactive and informed approach to fire safety. By adhering to current safety standards, implementing specialised lithium-ion battery fire extinguishers, and collaborating with local fire services, construction organisations can protect both property and lives from the dangers associated with lithium-ion battery fires. Recognising the fire industry’s need for specialist lithium-ion battery fire extinguishers. CheckFire, a leading specialist in fire safety solutions, launched its LFX range as part of its ‘The Green Range’ in 2024. These revolutionary fire extinguishers get to work instantly, removing a large amount of excessive heat, rapidly reducing the temperature, and cocooning the fuel of a lithium-ion battery fire in its infancy.

A comprehensive new, free online centre of building safety information has launched this month to help promote increased awareness of fire and life safety issues in the planning, commissioning, design, construction, surveying, maintenance, and management of buildings in the UK.   The Building Safety Wiki offers regular news updates, guidance, factual articles and expert insights on fire and building safety from a wide range of authoritative sources, all in one place.  Published in advance of the Grenfell Tower Inquiry final report and recommendations, the Wiki aims to help share vital knowledge and information regarding the new building safety regime in the UK, including the Building Safety Act 2022 and related fire safety legislation in all parts of the UK.   Much of the content is drawn from existing articles in the long-established Designing Buildings Wiki which already has more than 7 million users a year, 20,000 registered users and nearly 300 articles covering building safety topics.  That content, built up over more than 10 years, will be updated and added to on an ongoing basis.  Users can easily find relevant information for their projects or disciplines by using the Wiki’s search bar or quick links. Anyone can also contribute their knowledge and expertise to the Wiki, free of charge, adding or editing articles to fill any important information gaps.   The Building Safety Wiki is sponsored by LMC (Liz Male Consulting Ltd) and Enframe Consulting.   LMC is a public relations and communications consultancy that works with UK and international innovators, change-makers and thought leaders in property, construction and the built environment.  Liz Male, founding director of LMC, said:   “The new building safety regime affects all aspects of construction and the built environment, setting new standards, policies and processes to restore confidence in building safety. Yet in our conversations with professionals across the industry, we often find big gaps in knowledge, confusion about the new rules, or just assumptions that ‘this doesn’t apply to me’. The Grenfell Tower Inquiry report in September will shock the world yet again with its findings, so each of us needs to play our part in ensuring such a tragedy never happens again.”    Enframe specialises in construction and design consultancy for architects, providing expert technical guidance on the Building Safety Act.  Will Freeman, director of Enframe Consulting, said:  “This Building Safety Wiki is a significant step forward in creating a centralised hub for essential building safety information. Our mission is to provide a platform where knowledge is shared freely, contributing to safer building practices and ultimately saving lives. All architects, engineers, contractors and clients should have the knowledge they need to ensure compliance and enhance safety standards across the industry. I hope other fire and building industry experts will also come forward to keep adding vital information into this Wiki, and generations of students and industry professionals will benefit from the facts they learn here.”  Visit the Building Safety Wiki today at: https://www.designingbuildings.co.uk/Building_Safety_wiki  Building, Design & Construction Magazine | The Choice of Industry Professionals

The Business Sprinkler Alliance (BSA) was delighted to attend and host a stand at the UK’s Real Estate Investment and Infrastructure Forum (UKREiiF) on the 20-22nd May.  While the event provided an opportunity to engage with a diverse group of attendees, it also revealed continued gaps in knowledge about sprinkler systems among real estate professionals. The conference held at the Royal Armouries Leeds & Leeds Dock featured expert panels discussing sustainable and transformational investment in the built environment. Tom Roche, Secretary of the Business Sprinkler Alliance, was one of over 12,000 built environment professionals attending and lent his insight into the discussions, stressing the importance of business resilience and safeguarding commercial premises from the outset. The forum featured a series of sessions on a range of topics including the Building Safety Act, with Dame Judith Hackitt as a panellist in one. It was evident that significant effort and interest is still being directed towards remediation work. It was interesting to note the role that sprinklers were viewed as a tool to mitigate risk. Like so much of the changing regulatory environment there were repeated concerns raised by developers about the lack of clarity in the new regulatory regime. The obvious outcome being delays in programme approvals with consequent deadline and project financing cost. A surprising element was the undercurrent of struggles with true collaboration among stakeholders.  The wrapper to this appeared to be the sharing of knowledge and the need to foster and grow trust between all parties; developers, consultants, financiers, lawyers and insurers. On that topic one of the most surprising findings was the number of visitors to the stand across these stakeholder groups who admitted to discussing or making decisions about sprinklers without truly comprehending their benefits or how they operate. “We have known for a while that the knowledge gap surrounding sprinklers existed. What was surprising was that this gap persisted with those who  actively claimed to be involved in decisions about their provision,” said Tom Roche. “It’s concerning that such critical safety measures are being debated without a fundamental understanding of their capabilities and effectiveness.” The BSA also noted a lack of awareness regarding the provision of sprinklers under regulatory guidance. Many attendees naturally expected the hotels they stayed in and even the large exhibition spaces would be provided with sprinklers. They expressed shock upon learning that they often lack sprinkler systems, despite the number of people within them. Another strong stream within the forum was on sustainability. A lot of focus and attention was focused towards schemes that measure the sustainability of projects.  It sounded like a new form of accounting where all elements of carbon involved in the construction, operation and decommissioning of a project were weighed and measured. Given the need to address the sustainability challenge it was striking to see this attention and the number of people with a passion for this subject. The case for the re-use of buildings and materials was very strong.  What was striking to the BSA was again that that “shock” events like fire and damage to projects were not part of the thinking. Unfortunately, the potential for damage from a fire during the 50 year life of a building was not something that could be found in these programmes. One wonders if we are missing an opportunity or whether the “accounting” has a gap. On this note another element that came as a surprise was the discussion on  compartmentalising large warehouses to avoid sprinkler requirements. According to consultants at the forum, some clients are still pursuing this approach to avoid installing sprinklers in new warehouses, despite the obvious fire risks associated with such massive buildings. “After the recent large fire in Cannock, it was troubling to learn that some developers may be actively seeking ways to engineer out sprinklers,” added Tom Roche. “The scale of these buildings means that they are outside the scope of regulatory guidance and need real fire engineering solutions to ensure they are truly sustainable and do not endanger lives but also preserve valuable assets and investments at risk.” Despite these concerning findings, the three-day event provided an opportunity for the BSA to educate attendees on the multitude of benefits sprinklers provide for life safety, asset protection and environmental protection, and address misconceptions. By exposing the gaps in regulatory guidance and highlighting the consequences of neglecting fire safety measures, the BSA hopes to inspire a more informed and responsible approach to sprinkler installation across UK business buildings.
