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.

LSZH Cabling: The Next Step In Preventing Gas & Smoke Deaths In Fires
LSZH Cabling: The Next Step In Preventing Gas & Smoke Deaths In Fires

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.

Continuity Of Power Throughout Buildings Is Key During A Fire
Continuity Of Power Throughout Buildings Is Key During 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.

VIKING Safety Academy Offers E-Learning Solution For Training Delayed Due To COVID-19
VIKING Safety Academy Offers E-Learning Solution For Training Delayed Due To COVID-19

​​​VIKING Safety Academy has addressed a fast-emerging seafarer training issue brought by coronavirus by delivering a unique e-learning tool that can keep seafarers STCW compliant until restrictions on movement and social interactions come to an end. With many countries in lockdown, face to face seafarer training is also being suspended and some flag administrations have responded by granting automatic three-month extensions to the STCW Certificates seafarers must update every five years. However, VIKING Safety Academy has designed a unique training set-up so that seafarers can undergo training for a full certificate renewal even while the crisis persists. VIKING Safety Academy has worked with Estonia’s Reval Safety Training to offer STCW refresher training on an e-learning basis for Estonian seafarers. Personal Survival Techniques The training set-up includes: Personal Survival Techniques, Fire Prevention and Fire Fighting, Proficiency in Survival Craft and Rescue Boats, Fast Rescue Boats and Advanced Fire Fighting. “Seafarers can now use e-learning to train and renew certificates during these extraordinary times and maintain proof of competence,” says Camilla Runge Nissen, VIKING Safety Academy Product Manager, Training. "They can secure a longer six months extension and can make good use of the time getting ahead in the compliance process.” provisional STCW certificate Seafarers can visit a Reval Safety Training center during the six-month period for classroom/practical training Once the seafarer has completed the e-learning course, whether onboard or at home, he/she is given a provisional STCW certificate extension. Should conditions allow, seafarers can visit a Reval Safety Training center during the six-month period for classroom/practical training and secure a five-year Certificate of Proficiency, or complete once the crisis passes. While the STCW certificates extension based on e-learning is only available to Estonian residents for now, the course could easily be extended to other flag states, Nissen says. “All elements of the temporary package have been approved by the Danish Maritime Authority (DMA), we are already talking to other flag states and we can quickly roll this out.” digitally powered solutions The Norwegian Maritime Authority recently announced that it will allow seafarers onboard Norwegian vessels to join vessels until July 1st this year, even if they have only completed the theoretical relevant parts of STCW. “Under this guidance, e-learning is part of the picture, demonstrating that the set-up developed for Estonia can be very useful elsewhere.” Benny Carlsen, VIKING Senior Vice President, Global Sales and Marketing, adds that the new e-learning initiative aligns closely with group efforts to keep seafarers and owners compliant, safe, and as hassle and worry free as possible “free from stress”. “In extraordinary times, we need proactive and digitally-powered solutions to ensure that a training headache does not become a lasting issue.”

VIKING Life-Saving Equipment Secures Contract To Supply HydroPen Container Firefighting System For V.Ships Hamburg
VIKING Life-Saving Equipment Secures Contract To Supply HydroPen Container Firefighting System For V.Ships Hamburg

Container firefighting across the V.Ships Hamburg container ship fleet has been entrusted to the HydroPen system, after VIKING Life-Saving Equipment secured a contract to protect over 40 ships against one of the industry’s fastest growing safety hazards. Countering rise in container fires The alarming rise in the number of container fires has brought calls for urgent action from the International Union of Marine Insurance (IUMI), with stakeholders urged to encourage IMO to strengthen fire protection and review firefighting equipment onboard existing ships. Fighting a fire high up in the stack from the deck is often ineffective, with containers dowsed on the outside while materials inside continue to burn. As ship sizes have increased, so have stack heights. HydroPen Container firefighting system HydroPen system is based on an innovative drilling and spraying machine that allows deck crew to fight fires successfully The HydroPen system is based on an innovative drilling and spraying machine that allows deck crew to fight fires successfully high up in the stack. Developed by Rosenby Engineering and distributed exclusively by VIKING, the HydroPen unit is attached to existing ship hoses and raised by a single crew member using a telescopic lift. The HydroPen is powered by water pressure alone and drills through the container door before switching to spray mode to extinguish the fire with water, foam or C02. “For V.Ships, new technologies that support safety excellence are always welcome, while keeping customers ahead of the competition through innovation is one of our core values,” says Franck Kayser, Group Managing Director, V.Ships Ship Management. “HydroPen is an easy to use but ground-breaking system that addresses a specific industry concern. Its adoption fleetwide aligns with our ‘safety first’ commitment.” Container ship fleet fire safety VIKING will deliver 88 HydroPen systems to 45 V.Ships Hamburg container ships by February 2020. One unit will be positioned astern and the other towards the bow to enable rapid response. “Securing an order of this magnitude from one of the leading ship management companies in the world is a major vindication of the work behind bringing the HydroPen system to market,” says Lasse Boesen, Product Manager Trade, VIKING. Enhanced fire safety Lasse adds, “Several of the most recent container fires have occurred on very large ships. These ships can only call at a limited number of ports, making it critical that container fires are dealt with on board. The feedback that we are getting on HydroPen is that the system’s true value comes from its being so easy to use.” The HydroPen has already seen service, after a pilot system was used to extinguish a real fire at sea “We continuously seek to offer the very latest technologies to our maritime customers and in the HydroPen we believe we have a solution that will quickly become a ‘must-have’ to address a serious and widespread issue,” says Benny Carlsen, VIKING Senior Vice President. The HydroPen has already seen service, after a pilot system was used to extinguish a real fire at sea, he adds.
