Fire Detection: Protecting Food And Grocery Stores
Fire Detection: Protecting Food And Grocery Stores

During these challenging times, it is more important than ever to protect the supply chain of food, including supermarkets and convenience stores in cities around the world. On average 3,740 fires occur in food and groceries stores in the US annually, including supermarkets and convenience stores, according to a report published by the NFPA (National Fire Protection Association). Structure fires in mercantile properties were responsible for the loss of 12 lives and more than $600 million indirect property damages, and this doesn’t account for the cost of business interruption and the effect on the reputation of the store. Many stores haven’t been able to recover after a fire. The report estimates that a single fire may cost $46,000 on average, which in hindsight is considerably higher than investing in a fire detection system. The most common causes of fire in supermarkets It’s important to look at the data from two different perspectives. The first is the number of fires by cause, and the other is to quantify the property loss by cause. The report estimates that a single fire may cost $46,000 on average Fires caused by cooking equipment , including stores with kitchens and warming and portable equipment, account for 21% of incidences, but only for just 7% of total property damage and four civilian deaths (firefighter and first responder deaths are registered on a different report). On the other hand, electrical distribution and lighting equipment malfunctions and defective wiring account for 15% of the total of fires in a given year, but caused $165 million in property loss, or 27% of the total recorded on the report. It is also important to mention that intentional fires are the third cause reported, accounting for 11% of the total fire incidences and 20% of the property loss highlighted in the report. Occupation, materials and risks The kind of store poses a significant variety of risks associated to the type of occupation, the number of occupants and the materials stored and available in the shopping areas. It’s possible to find combustible materials of diverse nature and propagation speed. Cardboard and paper wrapping can be found in all store areas, including book and magazine stands. Cleaning products, oils and fatty products might have a high propagation speed. All of this, surrounded by different kind of plastics, immensely increase the level of risk. Overall, combustible liquids caused 41% of the civilian deaths recorded during the report In my firefighting years I’ve responded to several fires in food supermarkets and distribution centers, and saw tuna cans (canned with oil) exploding and spreading flames to the surrounding areas. Regarding occupation, it is known that supermarkets and groceries stores are places with high levels of occupation, especially during working hours. But one interesting fact that the report found is that fires occurring between 9pm and 5am can cause, on average, $73,800 in property damage. The NFPA estimates that 21% of human life losses happened between 12am and 3am. This highlights the importance of installing and maintaining an automatic fire detection system. Installing fire detection And Protecting Your Store With the variety of materials and the risk level that can be found in this kind of environment, it’s necessary to take a holistic approach. Fire protection should be designed while considering several angles, from passive protection in all interior and exterior structures and cladding to active protection with sprinkler and clean agent systems, proper ventilation and smoke control and automatic fire detection and evacuation systems. On average 3,740 fires occur in food and groceries stores in the US annually Several detection technologies need to work in parallel, depending on the type of products stored, the environment and the expected level of occupation on the protected area. Store height and ventilation need to be taken into consideration and also the kind of lighting in some cases. Depending on the ceiling height, the shopping floor could be protected with beam smoke detectors. If the ceiling is below six meters, or the store shelves obstruct the beam, it’s possible to use spot type smoke detectors. The same approach can be taken for warehousing and storage areas, but here I would recommend multi-criteria detectors, with heat and smoke detection combined. localized protection As I’ve mentioned before, cooking areas have an increased level of risk, which calls for localized protection. Here, I would recommend multi-criteria (smoke/heat) detectors for areas where food is heated and served, and smoke/heat/Carbon monoxide detectors on cooking areas to avoid nuisance alarms caused by cooking smoke and steam. It’s important to mention that until this year it was possible to install heat detection in cooking areas, but the UL 268 7th edition that comes into effect in 2021 will require cooking areas to be protected with smoke detection, and smoke detectors have to be able to reject nuisance alarms caused by cooking smoke and steam. Smaller supermarkets and convenience stores usually have vertical freezers or horizontal open freezers. Here, electrical and mechanical failures can ignite fires, which is why it is important to protect the rear side of the freezers. I would recommend point-type smoke detectors, as photoelectric smoke detectors tend to perform better on smoldering fires. The report mentions that air conditioning equipment and electrical equipment can be sources of ignition as well. To protect A/C rooms and electrical rooms I would recommend combined smoke/heat detectors, or maybe even smoke/heat/CO to assure better detection and avoid unwanted alarms in these business critical areas. There is a type of photoelectric smoke detector that uses two different LED sources inside the smoke chamber. This technology, called Dual-Ray, allows the smoke detector to identify the particles inside the chamber by size. The detector knows if it is sensing dust or steam, and can even differentiate between cooking or cigarette smoke from actual smoke from a smoldering fire. Bosch Building Technologies first introduced dual Ray technology in 2015. protecting the food supply chain During these challenging times, it’s more important than ever to protect the food supply chain and avoid the social and economic impact of fires in food stores, especially in impoverished areas. Supermarkets and convenience stores present a variety of challenges regarding fire protection, which calls for a holistic approach where passive and active protection are equally important. To achieve this target, one key element is automatic fire detection. Smoke and heat sensing technologies must be combined, and one size-fits-all approach is not enough. Detection and effective evacuation are critical to protect lives and minimize property loss.

Why Fire Safety Must Be A Priority When Reopening Businesses
Why Fire Safety Must Be A Priority When Reopening Businesses

With many businesses and facilities re-opening sites following the Coronavirus lockdown, fire safety may not seem high on the list to other worries and responsibilities. But here, Mandy Bowden, Fire Business Development Manager at Comelit Group UK, led by fire industry bodies, demonstrates why it must be a priority, ensuring installation of systems is guided by best practice in accordance with the development, and fire safety measures are maintained and regularly tested to ensure compliance. Fire safety is too often neglected. And in the midst of returning to work and implementing necessary fever screening solutions and social distancing policies, it may even fall further down the necessary requirements, for businesses who are naturally eager to open and ‘get going.’ Providing Fire Safety But the Government and leading authoritative fire industry bodies have made it absolutely clear that, “Coronavirus is not an excuse for disregarding your responsibilities and businesses must ensure that they have an adequate amount of competent people to help in the implementation of both preventative and protective fire safety measures.” Above all else, fire detection is there to save lives; but the way in which systems are presented, will depend on their surroundings. For many facilities it involves more than the best choice of products and services. It also requires compliance to standards, currently changing in light of the Grenfell Tower Inquiry, and a need to consider the environment that it serves to keep safe. fire detection technology It is crucial that buildings are fitted with the highest quality life safety systems to ensure ultra-reliable protection Style of a fire detection system would be considered a priority for a hospitality environment, including hotel and restaurant facilities, to blend with the aesthetics and not impact on the ambience created. In any leisure facilities such as a Gym, it is essential fire detection measures and systems are in place that will provide customers, employees and the premises itself, with sufficient prevention against fire at all times. To keep up with demand, a system needs to be simple to install and operational as quickly as possible for the benefit of members and staff. However, a manufacturing vicinity will require latest fire detection technology to ensure the safety of its building, its specialist products and all personnel who operate on site. Similarly, an art studio is a specialist consideration when it comes to fire safety, especially with the use of different materials and substances in every day works by the artists on site.  ensure ultra-Reliable protection Both temporary and permanent healthcare facilities in this period have undoubtedly been key to fighting the Coronavirus pandemic, and experienced an expediential increased demand for patient care. With more people to treat and protect, those working or residing within these spaces have to be considered at greater risk in the event of a fire emergency. It is crucial that these buildings have been and continue to be fitted with the highest quality life safety systems to ensure ultra-reliable protection. And the same is true for care homes, a vulnerable group in the fight against coronavirus. They require critical and reliable, functioning fire detection equipment that presents high performance protection, avoiding false alarms to prevent moving elderly residents unnecessarily. In each of these scenarios, the need to act quickly is paramount.  Fire Detection Operations Fire safety must be kept a priority to ensure a return to work can occur seamlessly and successfully In healthcare, immediacy is a common theme through the industry, be it providing treatment or responding to a patient’s symptoms. This is no different in fire safety, with detection systems requiring an ease of use, by anyone operating on site. In businesses returning to work ‘post-lockdown’ the appointed Fire Marshalls and responsible persons may not be the ones returning to office locations, so others need to be trained with simple to operate solutions. In summary, fire safety must be kept a priority, arguably now more than ever to ensure a return to work can occur seamlessly and successfully, and with an obligation of care to workers coming back to operating establishments. By understanding these environments and choosing systems accordingly, duty holders can ensure they reduce risks across their premises and maintain a safe ‘new normal’. multi-Sensor detectors Comelit presents its third-party accredited family of ATENA and ERACLE fire detection and fire alarm systems, which offers a diverse portfolio of intelligent, addressable products that are feature-rich, easy to install, simple to operate and offer incomparable reliability.

2020 Sees Increase In Popularity For Temporary Detection Systems
2020 Sees Increase In Popularity For Temporary Detection Systems

2020 introduced a variety of unique challenges for many industries around the world. Not surprisingly, the fire detection industry was not immune to all of those challenges. However, as much of the global community defined our manufacturing and installing peers as “essential” or “critical” it required us, as an industry, to adapt so we could continue to service our customers with our products and services. Many regions around the world are experiencing significant demand for temporary detection systems. This demand is almost universally driven by an increase in education, awareness, and enforcement. While this is a global shift, our company has experienced a large demand in our own backyard. Within the United States, this is being driven by the adoption and enforcement of NFPA 241. NFPA is the Standard for Safeguarding Construction, Alteration, and Demolition Operations. NFPA 241 has been a “concept” since 1930 and the official text was finally adopted by the NFPA in 1933. As with all standards, it has progressed over the years to accommodate changes in technology as well as safety awareness. Fire safety awareness While general safety awareness on construction sites has always been consistently high, fire safety awareness has significantly increased within the last 5 years. Nuisance alarms negatively consume first responder bandwidth Typically, new, or increased regulation within our industry occurs after a single devastating event or several significant events. In this particular case, it was a combination of both. On a national level, fires on construction sites were reaching dangerous and unacceptable levels and becoming so widespread that enforcement of this standard became a priority in several states. Need for accurate and timely fire detection According to a report released by Richard Campbell of the NFPA in February of 2020 titled Fire In Structures under Construction or Renovation, “the estimated number of fires in structures under construction has increased since 2014 after declining between 2008 and 2010” further creating awareness. For the last few years, the focus of many local AHJ’s (authority having jurisdiction) was on new and active worksites or renovation projects. With the changes imposed by the COVID-19 pandemic today, many non-essential industries have either shut down or had their operations significantly reduced. This means the need for a functioning detection system is more critical now than ever as many facilities remain idle or continue to operate with reduced personnel. Detecting fires quickly and accurately gives our first responders the best chance of saving a person or facility. Conversely, having any “detection system” is often not good enough. Nuisance alarms negatively consume first responder bandwidth, possibly removing an engine or fire company from a genuine event. Temporary fire detection In an article by The Boston Globe, Easthampton Fire Chief David Mottor, president of the Fire Chiefs Association of Massachusetts said “Ninety percent of these buildings go up every day and nothing happens. It’s during construction before the sprinkler system is activated when they are most dangerous.” Globally, we have seen four approaches to temporary detection for both construction and renovation sites. We will quickly discuss the advantages and disadvantages below: Using 24/7 fire watch Utilizing local first responders or other authorized/trained personnel to offer 24/7 fire watch requires a person or team of people to be onsite 24 hours a day, 7 days a week to be physically looking for fires. Advantage: Someone is always on site, actively viewing and patrolling the facility. Disadvantage: Maintaining a 24/7 fire watch can be expensive, further the person or team can only see/find fires in proximity to them as they continue to move about a facility. Using digital linear heat detection Digital linear heat detection is a fixed temperature detector that is constructed using a twisted pair of metal conductors that are separated by a heat sensitive polymer. When the ambient temperature meets or exceeds the detector’s fixed temperature the polymers melt, and the detector shorts out resulting in an alarm. Advantages: Detector can be easily installed at a new construction site or a facility being renovated. The technology is a low profile, non-intrusive and cost-effective form of detection. This automatic initiating device is immune to environmental conditions. Protectowire FireSystems offers Confirmed Temperature Initiation technology (mechanical damage does not cause a false alarm). Disadvantages: Detector can be mechanically damaged during normal worksite operation. If you are unsure, be sure to check with the local AHJ or call your insurance provider Using wireless spot detectors There are a few companies on the market that offer wireless spot detectors that can be networked together. Advantage: Typically, this technology uses a mesh network of detectors. The detectors and their bases are battery operated and can be moved or placed per worksite requirements. Disadvantage: This technology can be expensive. Physical barriers on the construction site may hinder mesh network operation requiring the purchase of additional wireless units. Many wireless technology providers focus on smoke detection. Smoke detectors are often not ideal for the harsh environments associated with construction (dust, temperature changes, etc.). Using a hybrid approach This involves using wireless nodes to supervise linear heat detection. Most manufacturers of the wireless systems offer a wireless node that can accept a third-party initiating device. Advantage: Wireless nodes can be placed anywhere, and linear heat detection technology can withstand the harsh construction environment. Disadvantage: Wireless node battery life can be reduced when using a third-party device. Less cost-effective approach. Solution for Facilities While each of the approaches listed above has its own advantages and disadvantages, you must always consider what is best for your facility. If you are unsure, be sure to check with the local AHJ or call your insurance provider. Established in 1938, Protectowire FireSystems is the global manufacturer of Linear Heat Detection Systems. The Company has been manufacturing in the United States for the past 80 years and counting. Protectowire is dedicated to delivering products designed, engineered, manufactured, and tested with a high degree of performance, reliability, and quality. As one of the manufacturers in the fire protection industry, Protectowire has the experience and knowledge needed to meet the ever-increasing detection challenges of the special hazard and commercial industries.

Morley-IAS ZX5SE Control Panel Based Fire Detection System Protects Chester Zoo
Morley-IAS ZX5SE Control Panel Based Fire Detection System Protects Chester Zoo

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.”

Morley-IAS By Honeywell Voice Alarm System Protects City Of London School
Morley-IAS By Honeywell Voice Alarm System Protects City Of London School

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.
