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.
Products for electrical systems that are installed into modern, complex buildings have to be fit-for-purpose for today’s challenging demands. With the background of numerous incidents still being felt by the fire performance industry, how is it to set the benchmarks for the future to make sure there is never another Lakanal House or another Grenfell? The long-term answer is for clearer guidance and legislation, if necessary, to enable the whole supply chain to make decisions which are compliant when choosing products. In the meantime, with the Grenfell inquiry projected to go on during 2019, what is the benchmark?The development of LSZH materials was accelerated following the King’s Cross Underground disaster in which 31 people died Cables With LSZH Materials We have standards through British Standards (BS) and testing regimes which cables should meet to validate that they meet these standards with approvals from various industry bodies including BASEC and LPCB. At AEI Cables, we have developed our Total Fire Solutions range of cables and accessories for all fire safety applications, incorporating Low Smoke Zero Halogen (LSZH) features. Traditional PVC cables which produce vast amounts of dense black smoke, toxic fumes and acid gas when exposed to fire, bring an added danger to people who may be caught in the fire. Cables which incorporate LSZH materials emit very little of these substances. In a real fire situation, the cables will enable the fire and rescue services to find and evacuate people and help to protect property Smoke And Noxious Gases Cause More Casualties The development of LSZH materials was accelerated following the King’s Cross Underground disaster in which 31 people died, many of them from toxic fumes. London Underground has banned the use of PVC cables as a result. The adoption of LSZH for cables and other materials is also endorsed by the Building Regulations themselves. According to Part B, referencing fire safety, it says clearly: “The primary danger associated with fire in its early stages is not flame but the smoke and noxious gases produced by the fire. They cause most of the casualties and may also obscure the way to escape routes and exits. Measures designed to provide safe means of escape must therefore provide appropriate arrangements to limit the rapid spread of smoke and fumes.” Helping Fire And Rescue Services The very latest in technology and science, including LSZH materials, offers enhanced fire performance cablingThe very latest in technology and science, including LSZH materials, offers enhanced fire performance cabling, accessories and technical support ensuring critical fire-safety circuits can continue to operate in the event of a real fire from 30 minutes up to 120 minutes. In a real fire situation, these cables will enable the fire and rescue services to find and evacuate people and help to protect property. At the same time, there is still evidence of non-approved cabling still coming onto the market, and we simply cannot compromise quality of these products being used in these applications. Applications include residential and commercial buildings, shopping malls, airports and protected buildings with a track-record ensuring that fire alarms, sprinkler systems, building monitoring and security systems can continue to operate in a fire.
The continuity of power in the event of a real fire has never been more important as modern buildings become more complex and the need for the highest quality of products comes under the spotlight. With power for lighting and fire alarms, the fire and rescue services can use the intelligence gathered to evacuate people quickly, confident that they have found all the people in the building. Without power, they are literally scrambling in the dark without good information upon which to make their rescue. The continuity of power will also ensure that sprinkler or water mist systems can continue to operate where they exist. In commercial buildings, there may also be smoke evacuation fans which help to enable safe evacuation. Fire alarms may be digital, with loop systems which will provide information for fire and rescue services Appropriate Cabling At the start of a project, the most appropriate cabling should be specified as part of the electrical system rather than at the end of a project. Fire alarms may be digital, with loop systems which will provide information for fire and rescue services across individual areas and floors. At the same time, there are new designs, materials and products continually coming on to the market for major projects, and with it an increasing need for the various parties involved to work closely together to make sure they get it right. There has been an increasing incidence of non-approved cables on the market and unfortunately it is not until cables have been installed, tested or used that issues become clear. For installers, or those procuring cables, there is a need to check the cable when it arrives to make sure it is exactly what was specified. Should there be a problem, have it checked and seek good advice. Keep records of purchase, including reel flanges with batch markings and a sample of the cable markings. Send lengths for testing and then decide on the most appropriate course of action. Choice of cabling is crucial at the start of major projects as issues may occur later Meeting Rigorous Third-Party Tests For some buildings, it is crucial to select the highest quality products to meet the most rigorous third-party tests and real-life fire scenarios. These include environments such as hospitals, schools and care homes where older people and children move about. Specifiers looking at new large public sector projects such as hospitals should refer to BS 8519 for the electrical supply, and the most relevant cabling system. It is crucial to select the highest quality products to meet the most rigorous third-party tests This Code of Practice specifies that the type of system selected during the design phase ‘should be derived from a detailed process of consultation with the relevant authorities’ and that ‘the design should be agreed at an early stage.’ The decision-making process for cable selection relevant for life safety and firefighting systems is clearly defined here. This covers three categories ranging from 30 minutes to 120 minutes fire survival time. Categories 1 and 2 cover means of escape for 30 minutes and then 60 minutes respectively, and these cables are tested in accordance with the relevant codes. Category 3 for firefighting to 120 minutes refers to power and control cables meeting the 120-minute test according to the relevant standards. It should be emphasised that only Mineral Insulated Cable (MIC) or a cable meeting the requirements of BS7846 F120 will meet this criteria. For clarity, BS 8519 does not take precedence over BS 5839 for alarm systems and BS 5266 for emergency lighting. In essence, choosing the most relevant cabling and electrical accessories which will continue to operate under fire conditions has become critical. Application Of Medium Voltage Cables As the incidence of non-approved cables continues then so the application of Medium Voltage (MV) cables into high-risk environments including hospitals, schools, care homes, industrial sites and sub-stations serving infrastructure sites also becomes critical. In the context off fire engineering, it is important to select the relevant MV Cables in these areas. Adhering to the latest regulations is no longer enough - there needs to be a risk assessment. In order to do this effectively, it is important to ask – are the fire safety procedures up to date? All AEI MV cables are third party tested and approved by BASEC. Educational establishments including schools, colleges and laboratories are some of the most prone structures to fire hazards The whole supply chain needs to take consideration of these areas where vulnerable people often move about such as children or elderly people in hospitals or care homes. The fire and rescue services may need a little more time than a conventional building including reading complex fire alarm information to ensure a safe rescue in the event of a real fire. Educational establishments including schools, colleges and laboratories are some of the most prone structures to fire hazards. This is due to ageing structures, high volume of combustible materials, and changing use in Science, Technology, Engineering and Maths programmes where more combustible and flammable liquids are being used. Concerns have been raised by architects and designers about fire protection regimes Sufficient Fire Risk Assessment Recent research by the Fire Brigades Union, for example, showed that a key focus for all educational institutions must be ensuring that there is an effective fire risk management process in place, delivered by suitable and sufficient fire risk assessment carried out by an expert in the field. The best practice under Business Information Modelling (BIM) and all best practice of fire safety engineering methods should be observed in conjunction with project partners. There have been concerns over a number of years around the fire protection regime for new buildings expressed by the architects and designers themselves. The Royal Institute of British Architects (RIBA) points to the delays to Approved Document B with regard to the relationship of Building Regulations to changing design and construction. AEI Cables provides a full range of cabling products through its Total Fire Solutions service RIBA says the virtual disappearance of the role of the clerk of works or site architect and the loss of independent oversight of construction and workmanship on behalf of the client is a further issue for concern. In essence, RIBA believes that future proposals for the fire safety regulatory regime should be informed by the specialist fire safety expertise of relevant professional organisations and groups, and also take full account of this wider set of construction industry AEI Cables provides a full range of cabling products through its Total Fire Solutions service with the support of its parent company Ducab based in Dubai, with the design, manufacture and supply of MIC, Firetec Enhanced or Firetec Power depending on specific needs. The choice of cabling and accessories should not be underestimated at the earliest opportunity to ensure the fire and rescue services are given every chance of success in rescuing people and saving property.

The world is changing. Trends in urbanization and population growth require more sustainable solutions to move the world forward. From a business perspective, sustainability means that companies can do good for the planet whilst also doing good for employees, communities and customers. As a fire and security business, Chubb protects businesses globally, helping to make the world a safer place. However, the very tool that is used to counter the threat of fire also poses an environmental and physical threat of its own. A fire extinguisher is a pressurized product and classified as hazardous waste. This means care must be taken in its disposal to avoid causing harm to people and the environment. Safe disposal of fire extinguishers There have been a number of cases recorded in the media of accidents occurring after fire extinguishers are not properly disposed of. When it comes to fire extinguishers, not all disposal methods are made equal. In reality, there are significant differences in safety and environmental impact depending on the disposal method one chooses. While domestic disposal is provided by the state, businesses are required to dispose of fire extinguishers themselves For example, there was a very serious incident of a fire extinguisher being carelessly thrown into the back of a rubbish-collection lorry. This might sound like a routine and harmless incident. However, the pressure of the rubbish-collection truck caused the ‘disposed of’ fire extinguisher to explode. Luckily, no one was injured, but the risk to the waste-collection workers and to the people in the surrounding area was significant. This incident could have been totally avoided with the application of the correct fire extinguisher disposal method. Businesses’ responsibility in disposal While domestic disposal is provided by the state, businesses are required to dispose of their fire extinguishers themselves. While most businesses are responsible, there are some who resort to illegal fly tipping. Earlier, a pile of 400 extinguishers was found dumped in the UK’s beauty area of the Peak District, causing an environmental risk as well as a danger to life. Points to note when one is looking to dispose of one’s fire extinguisher. The rating and type of one’s fire extinguisher. The point in its life cycle is one’s fire extinguisher, and if it been used before. If one’s fire extinguisher still pressurized, one must look to release any excess pressure and leave one’s fire extinguisher to settle for a few days. One is not to throw out one’s fire extinguisher and not leave it out in the street. Domestic disposal is available through recycling centers. Commercial disposal is available through one’s fire and security service provider. Safe processing, recycling and disposal Chubb Fire & Security Extinguisher Recycling Unit, a dedicated facility offering a service for the safe processing, recycling and disposal of fire extinguishers across the UK, recycled 85,784 extinguishers. The recycled plastic can be re-used in road-surfacing products, children’s play areas, rail production for aggregates, or simply recycled to have a new life as another product. Chubb has worked closely with the Environment Agency to develop safe, efficient and environmentally friendly processes, ensuring that that its site maintains its ISO14001 certification. Every business has a legal responsibility to protect its people, buildings and assets from the hazards of fire. Failure to do so can result in prosecution, even if one have outsourced the disposal to a third party. Part of this responsibility means ensuring that all firefighting equipment including extinguishers is maintained and serviced properly by a competent person. As with any pressurized container, a fire extinguisher should be treated with respect. In fact, a fire extinguisher can become dangerous if it has been mistreated or abused, or if it has reached the end of its life cycle. One must ensure one’s business complies, and always recycle responsibly.
