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.

Gent Vigilon Fire Alarm And Detection System Secures William Edwards School In Grays, Essex
Gent Vigilon Fire Alarm And Detection System Secures William Edwards School In Grays, Essex

A Gent by Honeywell Vigilon fire alarm and detection (FDA) system, incorporating the Response Plus paging system, has been selected to protect the pupils and staff at the renowned secondary school, William Edwards, in Grays, Essex, United Kingdom. The William Edwards School in Grays, which recently marked the 50th anniversary of its opening this year, required a full design, supply, installation and commission of a new Fire and Detection Alarm (FDA) system throughout the premises, as part of an ongoing refurbishment project. The proposed solution had to maintain a flexible design to incorporate any late changes while other building projects were also taking place. Gent fire detection and alarm system The system selected had to be fully flexible to allow us to build in capacity for the school’s growth" PFS Group Ltd. (formerly Premier Fire Systems Limited), part of the Gent 24 network of renowned independent fire specialists has been an Elite Systems Integrator for more than five years and was involved in the project from its initial stages. The highly experienced FDA specialists had to work within a very tight time period and complete the whole installation out of term time. Simon Ford, contracts manager, Premier Fire Systems Limited, says, “The main challenge was to meet the rigid program of requirements and guarantee that the work would be started and completed within the school summer holiday period, to keep any disruption to a minimum. The system we selected had to be fully flexible to allow us to build in capacity for the school’s growth, and the robust technology offered by Gent was the ideal solution.” Gent Vigilon Analogue Addressable FDA system The Gent Vigilon Analogue Addressable FDA system installed at the school incorporated the company’s Vigilon fire alarm panels and Vigilon repeater fire alarm panels, with a total of 281 devices. The system uses Gent’s S-Quad range of detection to ensure the management of the fire alarm system meets the highest technical sensing methods and standards. The Vigilon system was then integrated with Gent’s new wireless Response Plus paging solution. In the event of a fire alarm being triggered, the paging system will allow each school caretaker and fire marshal to receive instant notifications and precise location details on their wrist pagers. This will enable them to instigate the school’s fire safety procedures without delay, speeding up the response time and assisting in the evacuation process. Wireless Response Plus paging system The paging system will also cover a separate house owned by the school on the far edge of the grounds, which is currently being used to offer exchange teachers a place of stay during their time at William Edwards. As the building is remote and regularly unoccupied for lengthy periods throughout the working day, the onsite paging system will overcome these challenges by reporting any fire present within the house, to enable the staff to react accordingly.  The school class change and intruder alerts were also added to the system" Simon Ford continues, “The client is very satisfied with the performance of the products installed, particularly with how easily they integrated into the entire school system. The school class change and intruder alerts were also added to the system and it has performed seamlessly since it was installed.” System installation and service The installation has resulted in repeat work for Premier Fire Systems Limited, and recommendations to other academy schools have been achieved for its business. Donald McFarlane, UK & Ireland Business Manager, Gent by Honeywell said, “We’re delighted to hear the very positive feedback from William Edwards School and we’re glad that the performance of our FDA solution meets the high standards of this outstanding institution.”

Gent Compact Aspirating Smoke Detection Units Installed At Camden’s Highgate Mental Health Centre
Gent Compact Aspirating Smoke Detection Units Installed At Camden’s Highgate Mental Health Centre

Gent by Honeywell has supplied an aspirating smoke detection system to the Camden Islington NHS Foundation Trust. It was designed and installed by long-time Gent elite system integrator PFS Group Ltd., (formerly Premier Fire Systems Limited). The new solution replaced the existing optical smoke detection devices within two mental health wards within the Highgate Mental Health Centre in Dartmouth Park Hill, London. According to Simon Ford, Contracts Manager, PFS Group Ltd., a new system was needed within the patient accommodation rooms. Compact Aspirating Smoke Detection units We selected the Gent by Honeywell Compact Aspirating Smoke Detection units, powered by EN54 power supply units" Simon said, “We selected the Gent by Honeywell Compact Aspirating Smoke Detection (ASD) units, powered by EN54 power supply units. One of the specific requirements for the system was to ensure that it could clearly identify the source of a potential fire, down to the individual room. This was accomplished by using the IDENT functionality of the Compact ASD devices.” The Compact ASD units are able to detect fires quickly, faster than point or beam smoke detectors. This often occurs before smoke is even visible, which provides users with valuable prevention time before an open fire can develop. These units are particularly well suited for use in high risk applications, such as medical facilities. Gent Vigilon Fire Network “The ASD devices were fitted within nurse stations and then connected to the hospital’s existing Gent Vigilon Fire Network using new addressable four channel interfaces,” says Simon Ford. PFS Group Ltd. worked closely with hospital ward managers and staff during implementation to keep the impact of work on patients to a minimum. Fire safety system implementation Simon concluded, “We’ve had some really positive feedback from the client regarding the implementation and the system, and we’re hoping that this serves as a pilot for a potential roll out to other wards and hospitals.”

Birmingham's Westside One Chooses Gent Fire Detection And Alarm System To Attain Highest Level Of Fire Protection
Birmingham's Westside One Chooses Gent Fire Detection And Alarm System To Attain Highest Level Of Fire Protection

Westside One, a residential building located in Birmingham city center, was constructed little over a decade ago yet its old addressable fire system was ageing rapidly and did not comply with current regulations. Midlands-based fire safety solutions specialists, Fire Safety Services Ltd., who are known for providing the maintenance for the multi-story premises, encountered recurring problems with the existing fire detection and alarm system (FDA), and recommended a complete upgrade to provide the ultimate protection to the building’s occupants. Gent fire detection and alarm system It was important to upgrade the system and select a new solution to bring it up to the current safety standards" Dave Lewis, Fire Systems Manager, Fire Safety Services Ltd., has said, “With the original system there were no sounders other than in the concierge area and the smoke vent doors were not integrated into the main system. It was important to upgrade the system and select a new solution to bring it up to the current safety standards”. Westside One is located on the busy Suffolk Street Queensway in Birmingham and is a 13 story tower block made up entirely of living accommodation. In a building of this nature, the FDA is a crucial element for the protection of the residents, any changes to the system have to be carried out quickly and efficiently to ensure the building is without coverage for the least possible amount of time. S-Quad detectors with optical heat sounders Fire Safety Services selected a Gent by Honeywell two loops Vigilon Compact solution to cover the entire apartment block. A total of 76 devices were installed, including S-Quad detectors with optical heat sounders and interface units to operate the smoke vent doors. The new solution would allow the alarm to be raised on every floor throughout the building and has been programmed to operate the smoke vent doors in emergency situations. As one of Gent 24’s network of approved Systems Integrators, Fire Safety Services Ltd. has had a close working relationship with the fire industry expert for more than seven years. Gent Vigilon Compact solution Dave Lewis states, “The biggest challenge for Westside One was the fact that it is an occupied building. The amount of downtime in between taking the old panels out and installing the new ones had to be kept to a minimum. We needed to get the system up and running quickly and the Gent system saved us valuable time”. He further adds, “On a typical system upgrade of this nature the average time for installing and commissioning is approximately five working days, this project took just three and a half days from start to finish.” Fire Safety Services worked hard to get the detection back in place as rapidly as possible. The team’s familiarity with the Gent technology was a key part of the quick turnaround alongside the flexibility of the system. Robust fire protection solution The high quality Gent FDA system in place is fully compliant with the current standards Dave explains, “The Gent solution provided the ease of install that we required, there was no extra cabling as we were able to use the existing cables. This saved both time and money, so it was an ideal, cost effective solution for the client.” The Westside One project is now complete. The high quality Gent FDA system in place is fully compliant with the current standards, and provides the building’s occupants with the robust protection and peace of mind that is essential in residential accommodation. Honeywell Gent fire detection systems Gent by Honeywell is synonymous with quality and innovation in the fire detection and alarm industry. Honeywell Gent fire detection systems have been developed to the highest possible standards to deliver the most advanced fire detection and alarm system available in the market today.
