The Grenfell tragedy has shocked the public and rocked the construction industry. The ongoing inquiry into the 2017 tower block fire has exposed huge flaws in existing practices across architecture, material specification, and building projects. It is also reinforcing the critical importance of fire protection. It took Grenfell, and admittedly the many years that have followed, for the industry to fully reappraise the product selection and testing regimes needed to ensure resident safety in buildings. Now, the tide is really starting to turn. Fire protection training Research we conducted across the UK, Germany, and France, in the aftermath of the disaster, revealed that knowledge levels surrounding fire and fire protection amongst some of our most trained professionals in architecture was very low. Across the three countries, only 3% of architects were able to correctly define the four basic fire protection terms: active fire protection, passive fire protection, fire resistance, and reaction to fire. Of the architects surveyed in the UK, 8% were able to define the four terms, in France, it was only 6%, and in Germany none. Hardly any of the architects interviewed, a mere 2%, said they’d had comprehensive fire protection training, most had some training, and less than one in ten (8%) say they’ve never had fire protection training. Fire-Protected buildings It was clear, post-Grenfell, that things needed to change, ensuring fire awareness is a top priority Our research confirmed that architects and specifiers had limited knowledge of fire protection and a lack of training in the area of designing safe, fire-protected buildings. It was clear, post-Grenfell, that things needed to change, ensuring fire awareness is a top priority, no matter how much time pressure industry professionals are under. And now they have. I believe that when COVID hit in spring 2020, a window of opportunity opened for fire protection awareness. Working together seamlessly Overnight, the majority of us were confined to our homes and adapting to working remotely where possible. For some businesses - such as ours here at Zeroignition - it had very little impact. Zeroignition is a global company and we have always operated remotely, enabling us to hire the best possible experts from around the world all working together seamlessly, remotely, and across 10 time zones. For other businesses, particularly architects, specifiers, and building consultants within the construction industry, this shift, which remains the same almost a year on, provided a very different way of working. A way that has now been proven to really work. Benefits of homeworking Online webinars have covered a variety of different topics including fire safety The benefits of homeworking are plentiful. One of the major benefits is time, a luxury many of us just didn’t have pre-pandemic. Now there’s no commute to work, to meetings, and to events. As exhibitions and conferences could not take place last year, many moved online, giving industry professionals the chance to engage and learn from the comfort of their own home, often at a time to suit their personal schedule. Since the outbreak of the pandemic last March, it has been reported that a whopping 49.2% of the British workforce were intent on investing time to actively further their learning. The NBS, (formerly National Building Specification) says it has seen a dramatic increase in webinar attendance. Eager participants include product manufacturers and also architects and specifiers. Online webinars have covered a variety of different topics including fire safety. Fire protection standards At Zeroignition we know that education is non-negotiable when ensuring buildings are built safely. Government regulations are being tightened to save lives, and as an industry, those of us in the business of design and construction must also continue to challenge ourselves to know more in order to meet incredibly high fire protection standards. Increased knowledge, coupled with a systematic approach - where products are seen together as a system, rather than individual components - would turn our methodology on its head for the better. Traceability is also a key component to add to the mix. One of the biggest failings unveiled by the Grenfell inquiry was the lack of traceability of products used for the building refurbishment. Investing in research and Development The introduction of a new regulator will help to ensure materials used when constructing buildings are safe This just wouldn’t happen in other industries such as aviation, or automotive, where every component of the structure is known and recorded. The introduction of a new regulator will help to ensure materials used when constructing buildings are safe, fit for purpose, and 100% traceable. Companies must be ready to stand up, take responsibility, educate themselves and invest in R&D to enable them to do things properly. The companies we’ve spoken to are willing to be more transparent, and share a product’s journey from testing, through to manufacture, installation, and maintenance, which is so important and really promising to see. Filling knowledge gaps From the very beginning, we’ve been challenging the industry to improve. To learn more. To try harder. To think differently. I can attest from our conversations with manufacturers that safety elements including fire safety have risen to the very top of the agenda. Never before have I seen companies so invested in R&D to enable them to build smarter, better, and safer – and consign appalling events like Grenfell to the history books. The pandemic has given the opportunity to invest time in filling knowledge gaps. So let’s continue to invest time in education and personal development to do better. Because it really matters. Change is imminent and safety is at the forefront.
With Grenfell inquiries continuing to uncover a number of fire safety issues, it’s clear that decision makers must learn from critical mistakes in a bid for better fire safety standards. Karen Trigg of Allegion UK highlights the key lessons that must be taken from Grenfell to help ensure a disaster of this magnitude never happens again. On the 14th June 2017, UK witnessed a tragedy. A myriad of critical issues, whether the result of mistakes, oversights or neglect, led to the largest fire disaster in modern memory - Grenfell Tower. Since then, the Grenfell Tower Inquiry has taken steps to uncover what went wrong that morning. But equally important is identifying and learning from the fire safety issues that were in play that day, so as to help ensure an incident like this never happens again. Taking Responsibility With that in mind, decision makers, construction companies, installers and manufacturers are amongst those that, in reviewing the reports, can make clear, steadfast plans to help improve fire safety for everyone. For that, a change in education towards fire safety - and the various solutions that make it possible - must be at the forefront of one’s activity. Because in reality, one is not just talking about ancillary products here, but lifesaving solutions. In November 2020, it emerged that Grenfell Tower suppliers were aware their cladding was dangerous In November 2020, it emerged that Grenfell Tower suppliers were aware their cladding was dangerous, with an inquiry citing, “These companies knew their materials would burn with lethal speed”. Despite the inquiries still bringing issues to light years later, it’s important to move forward on the critical topics that have already been identified. safety hardware manufacturers Aside from cladding, from the viewpoint of fire safety hardware manufacturers, two other key issues stood out from the reports; the failure of compartmentation and flat entrance doors failing to close. Combined, these themes proved fatal. Compartmentation in particular is crucial to containing the spread of fire from one area (in this case, apartments) to another, giving building occupants a safe space and protection from the fire. Commonly, over a building’s lifespan, compartmentation can become compromised with a number of different retro-fitted products. With this, installers (who may not be fully aware of the importance of fire protection) can potentially leave holes where there were none before, thus giving fire and smoke a place to breach the defenses the building once had. On this occasion, learning from the fire doors - which also play a critical part in compartmentalization - is key. ineffective fire doors As stated in Phase I of the Grenfell Inquiry, “The performance of fire doors in the tower, in particular, whether they complied with relevant regulations, their maintenance and the reasons why some of the self-closing devices do not appear to have worked.” In the same section of Phase I, it was made clear that ineffective fire doors allowed smoke and toxic gases to spread throughout the building at a quicker rate than they should have. The market has developed to offer solutions designed to meet the many needs of a building and their users The absence of effective self-closing devices in part led to the failure of compartmentation and was therefore a reason why the doors failed to perform their essential function. With this in mind, it’s important to remember that fire doors (when operating with fully functional hardware) play an essential role in preventing or inhibiting the spread of smoke and toxic gases and are a key factor in preserving effective compartmentation in buildings. delayed closing mechanisms With this information, questions must be asked as to why there was an absence of effective self-closing devices? There could be many reasons as to why there was a lack of self-closing devices, for example, the doors being too difficult to open, or perhaps closing too quickly and were thus removed. Yet the removal of those devices is never the true answer and instead it puts residents at risk. Today, the market has developed to offer solutions designed to meet the many needs of a building and their users, including those with delayed closing mechanisms that can ease access and egress. Yet it’s key to remember that fire doors and their accompanying hardware are there to save lives and property in the event of a fire and can only do so if the correct solutions are present and correctly installed. fire safety education The lessons taken from Grenfell must further prompt an area which is still not as good as it needs to be - fire safety education. It’s fundamental to ensure facility managers, installers and residents all understand the importance of fire safety solutions - from why they’re there to how they operate. The installation process is paramount, too. There are common issues with installation that simply must be ironed out. Aside from this, stricter guidelines need to be implemented as a way of preventing fire incidents such as Grenfell Commonly, the speed to which installers are required to work isn’t leaving enough time for door closers to be fully adjusted and therefore suit the environment in which it’s being fitted. To combat this, suppliers must do what is necessary to support installation - from supplying self-adhesive templates to improve efficiency, to offering spring adjustable door closers which are perfect for time-impaired installers. preventing fire incidents Aside from this, stricter guidelines need to be implemented as a way of preventing fire incidents such as Grenfell. Fire safety solutions such as door hardware are accompanied with certifications but should stricter guidelines be in place for those installing them? Furthermore, when it comes to testing, should higher risk buildings not be treated in the same vein as the everyday vehicles where regular servicing and MOTs are required to ensure they continue to perform? These, amongst others, are the questions that must continue being asked. Finally, a push for improved competence across the board is key. From the product design stage right through to constructing, inspecting, assessing and managing and maintaining all public buildings, including higher risk residential buildings as Grenfell once was. Only when key mistakes are learnt from, and competent bodies placed in the overseeing of refurbishments or new builds of high-risk residential buildings, can everyone truly feel that they are one step closer to complete fire safety
Every day, across the globe, emergency services teams come to people’s aid no matter the situation to ensure their safety. Whether it’s during a natural disaster, or at a significant event, the emergency services are on hand to face any challenge that comes their way. When supporting this crucial workforce, it is essential that they have robust and reliable connectivity. Technology is becoming a vital aspect of public safety and security worldwide, and this trend is only likely to grow. For these new devices to work effectively, full-scale coverage must be in place, and when it comes to people’s safety, there is no room for error. The need for redundancy and high bandwidth Two of the paramount tools at emergency services disposal are video surveillance and communication devices. Constant visibility and communication are often essential to protecting people and saving lives. The benefits range from providing first responders with a clear picture and understanding of the situation they are about to encounter; to providing greater safety during public events by enabling officers to control crowds and manage traffic effectively. Enhancing visibility and sharing information is particularly crucial during fires to guide firefighters and vehicles through flames and smoke, and to allow the central command center to organize resources effectively. Technology is becoming a vital aspect of public safety and security worldwide, and this trend is only likely to grow Despite any potential challenges ensuring network connectivity may create, public safety organizations cannot compromise when it comes to optimizing security. For IP video surveillance and cellphone broadband connectivity to operate effectively, they require redundancy and high bandwidth. Without these connectivity attributes, devices become useless; for example, there are municipalities where as much as 50 percent of the camera network is offline because of poor product choices and inferior network design and installation. Equally, poor quality networking can be just as limiting as it can lead to public safety organizations being unable to receive real-time data. All areas must also have adequate bandwidth to access data, such as on-scene video, aerial imagery, maps, and images, and many existing public safety networks do not have that capacity. Supporting security and safety robotics Robots and drones have seen a considerable increase in popularity this year, with 60 million such machines being deployed according to ABI Research. They offer a wealth of potential to emergency services teams, whether on land, air, or sea. For example, water rescue robots can go where humans cannot, earthquake and fire robots can search through otherwise non-navigable areas, and drones can survey vast regions. However, for these wireless devices to work effectively, they rely on many features. They need low power consumption so as not to heavily burden the onboard power source of the robotic device and, perhaps, a high level of encryption so information cannot be stolen or hacked. There are also benefits to security and safety as robotic devices can communicate with one another peer-to-peer. Directly mounting radios to robots and drones, fosters dynamic self-learning, data sharing, and more wireless paths in the event one or more of the devices in an area do not have a link to fixed infrastructure. Water rescue robots can go where humans cannot, earthquake and fire robots can search through otherwise non-navigable areas, and drones can survey vast regions The main component that security and safety robotics require is redundant and resilient connections. If the connection is lost, the connected device will go into “safe” mode and stop. Creating a high capacity network that supports mobile devices in complex and fast-moving environments is not a simple task. In many cases, it requires a network that supports many wireless connections and allows for many paths in and out, so that if a link is lost, another path is available for data transmission and reception. This type of network is the best way to ensure that police, firefighters, and emergency units can access and send large amounts of data from wherever they are and in real-time making a massive difference to the efficiency of the emergency services. An example of this is Rajant’s private Kinetic Mesh® network, a wireless network ensuring no single point of failure. It offers reliable, intelligent, and secure wireless broadband connectivity that survives and thrives in evolving and mobility-driven environments. It forms a “living” mesh network that can move with and adapt to the evolving communication requirements of public safety organizations. Technology in action Back in October 2019, the heat from the sun, combined with winds gusting through the foothills of El Capitán Canyon in California, sparked a bush fire in the overly dry, desert hills. Despite four hundred and twenty acres being burnt, firefighters used their experience and skills combined with newfound digital technology to ensure that no structures were damaged, and there were no reported injuries. The Santa Barbara County Fire Department, Cal Fire, the U.S Forest Service, and other agencies were immediately dispatched to contain the fire. More than 200 firefighters were needed to combat the fire and reinforce containment lines with helicopters and drones in the air and bulldozers on the ground. To operate this equipment, mesh radio nodes, bonded cellular, and satellite technologies were used to link the communication gap in locations where signals are often dropped. Rajant BreadCrumb® nodes were mounted to the fire-breaking, 30-ton bulldozers manned by trained firefighters to uproot vegetation and eliminate the materials that would further spread the fire. Robots and drones have seen a considerable increase in popularity this year, with 60 million such machines being deployed The reliable connectivity allowed the bulldozers to not only easily communicate with each other and the base, but also to send video footage and data to the tactical truck and central command post over cellular and SAT networks. This situational awareness data transfer allowed for greater efficiency, as well as increased safety for the public and the firefighters. Reliability when you need it most Reliable connectivity solutions are being embraced across the emergency services due to the innumerable benefits they bring to ensuring the safety of the public. For police, firefighters, and emergency units, dependable connectivity allows for rapid, real-time response, and the use of technology can save lives in ways that wouldn’t have seemed possible a decade ago. Planned and unplanned events can benefit from the new technology being introduced, and emergency services need to make sure they have the network capabilities to support them. For environments that are challenging and hostile, this requires a network available on-demand, which can withstand the demands of harsh conditions and mobility while maintaining a level of redundancy and high bandwidth that allows for accessing and sending large amounts of data from any location.

Also, Honeywell D1 system and All-Spec air sampling device were installed at the zoo In 1930, George Mottershead bought Oakfield House in Chester, along with seven acres of land, for the grand total of £3,500. He then visited a zoo in Manchester and what he saw that day inspired him to create ‘a zoo without bars’. George opened Chester Zoo in 1931 with his family and a small group of animals, never forgetting the vow he made. By the time he died in 1978, aged 84, Mottershead’s dream of a ‘zoo without bars’ was well and truly flourishing. Fast forward to 2015 and with more than 12,500 animals in 125 acres of award-winning zoological gardens, Chester Zoo is one of the world’s top attractions of its kind. 1.4 million people visit every year and its mission is to be a major force in conserving biodiversity. The latest attraction is Chester Zoo’s Islands, which aims to transport visitors to the South East Asian islands of Panay, Papua, Bali, Sumba, Sumatra and Sulawesi. Work began on the £40m, 60,000m² development in 2013 and it has taken almost two years and thousands of working hours to build. The largest indoor zoo exhibit in UK history, Monsoon Forest is the centrepiece of the Islands and the second phase of the project to be completed. Islands gives visitors the chance to take a walk or boat ride past turtles, Sumatran tigers, cassowary birds and many other species, as well as through bamboo copses and rice paddies. It is also home to the Sundra gharial, one of the world’s largest crocodiles, whose habitat is cleverly set out so these remarkable creatures can be seen both above and under the water through spectacular glass viewing windows. An advanced PA/VA and fire detection solution Crown House Technologies (part of Laing O’Rourke) is the M&E contractor for the Islands project and sub-contracted Morecambe based Cook Fire & Security Ltd to provide the fire detection system for the Monsoon Forest. Joe Weiss, Technical Director at Cook Fire & Security, states, “Over the last 14 years we have become one of the leading installers of state-of-the-art solutions throughout the north-west of England and beyond. We have been involved in some highly prestigious projects but the Monsoon Forest was a unique environment and required some significant thought about the best way to protect, staff, visitors and, of course, the animals.” A Honeywell D1 system allowed Cook Fire & Security to combine advanced audio management with a flexible architecture to deliver an advanced PA/VA solution at Monsoon Forest. Generally, this type of technology is utilised in public or larger buildings and, following the detection of smoke or fire, automated messages control the flow of people, allowing an orderly evacuation without panic. However – as animal welfare is at the very heart of Chester Zoo’s activities - one of the key priorities was to have a PA/VA system that could alert staff and visitors without causing distress to the creatures living there. Joe Weiss comments, “Obviously, the animals are used to the sound of human voices, so we felt that a PA/VA system would be more appropriate than the type of loud siren commonly used.” Monsoon Forest is entirely enclosed and with temperatures reaching highs of 80°F, this level of humidity meant that a great deal of consideration had to be given to the most suitable fire detection system. A solution based around the Morley-IAS ZX5SE control panel was installed in the keeper’s section, as it is intuitive to use and easy to install, network, configure, maintain and expand. The public areas, however, required a solution that could offer high levels of false alarm prevention while blending in with the tropical surroundings. An aspirating smoke detection system Explaining the thought process, Weiss says, “Due to the height of the roof, access for installation and maintenance of a conventional or addressable system would have been problematic. Also, the high levels of moisture would have also been a problem and could have triggered false alarms. Therefore, an aspirating smoke detection system was the most suitable option.” A Honeywell All-Spec system was chosen and Martyn Keenan, Business Manager (North West) for Morley-IAS says, “As a universal air sampling device for a broad range of applications, All-Spec makes it possible to achieve a cost effective solution in accordance with EN 54-20. This allows the devices to be used in areas where other smoke detectors and air sampling smoke detection systems are no longer suitable, such as Monsoon Forest. By putting water traps on all pipework going back to the control panels, an extra level of false alarm detection has been achieved.” A highly innovative way of installing the system was employed, as the pipework was fitted when the roof interior was on the ground and then hoisted into position. This eliminated the need for access equipment and ensures that the environment will not need to be disturbed during any planned maintenance. Aesthetics were also important and white plastic was used to ensure that the system blended into the overall appearance of the roof structure. Ian McIntosh, health & safety manager at the zoo at Chester Zoo is delighted with the fire detection system that has been installed, and concluded, “The response to Monsoon Forest since it opened has been terrific and it is now a key part of the Chester Zoo experience. However, we also value the role that technology plays in keeping our staff, visitors and animals safe, which is why having Honeywell fire detection technology installed by Cook Fire & Security gives us peace of mind.”
Security alert buttons have been installed at first-floor staff entrance along with a fire microphone The 1,000 pupils and staff at the 570-year-old City of London School – one of Britain’s most photographed educational establishments – are now protected by a Morley-IAS by Honeywell voice alarm system. Installed by Ardent Fire & Security in a major overhaul of voice alarm and public address technology, the school, which is on the Thames embankment near St Paul’s Cathedral, now has a highly customised system that provides safety cover throughout its prominent site. A highly-customised Honeywell voice alarm system Replacing the previous obsolete system, Ardent, a Morley-IAS distributor, installed the Honeywell D1 rack and amplifiers along with 32 new speakers and new alert buttons. The buttons can be pressed to trigger specific public address messages in locations such as the swimming pool area and playground, while announcements can be made from both the reception desk and the office of the head teacher’s personal assistant. In the event of an alert, one of 18 separate safety messages is issued over the system, each of which is tailored to the school’s particular requirements. This allows disruption to be kept to a minimum, without compromising safety. In addition, security alert buttons have been installed at the first-floor staff entrance along with a fire microphone for the use of emergency services. As well as installing new speakers to ensure coverage is provided throughout the school, Ardent also optimised the operation of the in situ public address speakers. With its origins in the reign of Henry V, the school occupies a prominent site close to the Millennium Bridge, making it possibly the most photographed school in the UK. An independent day school owned and governed by the City of London, its former old boys include Sir Walter Raleigh and long-serving 20th Century Prime Minister Herbert Asquith. Integrated existing fire protection system, Morley-IAS control panel, and PA system The work was completed in two-and-a-half weeks during the Easter holidays and followed Ardent’s successful upgrade of integration between the existing fire protection system, a recently installed Morley-IAS ZX5Se control panel and the public address system. “The D1 system has amazing software with incredible flexibility – meaning it could do all that the school required,” said Adam Sutherland, Ardent director. “Any other system would have required a huge amount of re-cabling, but the D1’s sensitivity means it can work superbly with the existing infrastructure.” Currently based in Chelmsford, Ardent Fire & Security has staff with long industry experience, providing a full range of fire system expertise including PA systems and large network panels.
