RECHNER Industrie-Elektronik FIRE SUPPRESSION SYSTEM ACCESSORIES

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.

The fire industry has made it absolutely clear, led by authorized bodies including the BAFE Fire Safety Register, that the current pandemic does not remove the need to comply with any fire safety requirements under the Building Regulations. As we now look beyond the lockdown period, John Allam, Operations Director at Amthal Fire and Security reviews the raft of new proposals demonstrating the Government and industry’s commitment to compliant fire safety and new immediate demands placed on responsible persons. Multi-Occupancy residential buildings Whilst the second phase of the Grenfell Tower Inquiry has been put on hold until July at the earliest over coronavirus restrictions, the government has continued its quest to effect change and bring the Fire Safety Bill and Building Safety Bill into legislation. While the Building Safety Bill will ‘place new and enhanced regulatory regimes for building safety and construction products’, both bills aim to strengthen the ‘whole regulatory system’ for both building and fire safety. The Fire Safety Bill will apply to England and Wales, to amend the Fire Safety Order 2005 and seeks to clarify responsibility for reducing fire risk in multi-occupancy residential buildings. The details of the Fire Safety Bill, which has now had its second reading in the House of Commons, includes recommendations of regular inspections of lifts and sprinkler systems for buildings over 11m tall. Quarterly fire door inspections Building owners will now face ‘enforcement action’ from emergency services if they do not manage fire risk Significantly, it also introduces compulsory quarterly fire door inspections, which is a hugely significant development in its own right, to influence an industry where this is no specific legislation that requires fire doors to be checked. The Fire Safety Bill intends to ensure evacuation plans are reviewed, regularly updated and communicated to residents in a ‘form that they can be reasonably be expected to understand.’ And it highlights the importance of individual flat entrance doors, where the external walls of the building have unsafe cladding, comply with current standards. This will play a key part in increasing residents’ fire safety, whereby building owners will now face ‘enforcement action’ from emergency services if they do not manage fire risk in a building’s structure. Improving the fire safety of buildings In addition, the government is consulting with the National Fire Chiefs Council to begin testing evacuation alert systems for high-rise blocks of flats, which could support fire and rescue services’ operational response by alerting residents if they need to escape. The National Fire Chiefs Council to begin testing evacuation alert systems for high-rise blocks of flats The new program will be governed by a Building Safety Regulator (BSR) that will initially be led by Dame Judith Hackitt during the set up phase, who will be tasked with improving the fire safety of buildings. Launched by The RT Hon Robert Jenrick MP Secretary Of State for Housing, Communities and Local Government, he cited the new program as taking, “Ambitious steps to further reform the building safety system with the biggest changes in a generation to ensure residents are safe in their homes.” He added: “This new regime will put residents’ safety at its heart, and follows the announcement of the unprecedented £1 billion fund for removing unsafe cladding from high-rise buildings in the budget.” Major regulatory decisions The BSR will be responsible for all major regulatory decisions made at key points during design, construction, occupation and refurbishment of buildings. And such decisions and obligations must be upheld and maintained throughout a development’s life. The new safety case regime will apply not only to new buildings, but also to buildings that are already in use" In Dame Judith’s own words: “When introduced by the new regulator, the new safety case regime will apply not only to new buildings, but also to buildings that are already in use and occupied. If those buildings were built to poor standards in the past, it will not be the case that you can simply say ‘well it complied with building regulations at the time’. The test will be different. The test will be ‘is this building safe to be occupied?’ and, if not, what are you going to do to improve it?’ … People will be asked to think about what they can do, what is reasonable and what is practicable to do in order to improve the safety of a given building.” Regulating the fire safety industry Both Hackitt and the Government want the BSR to be set up in shadow form before the Building Safety Bill becomes law. The plan is to put the bill before Parliament by the autumn, despite the challenges thrown by the Pandemic. The new legislation proposed by Government will undoubtedly ensure that buildings and those that live and work in them are maintained to be fire safe. In the words of BAFE CEO Stephen Adams: “The time is right to help better regulate the fire safety industry to change end user behavior and create a UK that's safer from the devastating effects of fire.” As BAFE further attests, as lockdown measures begin to be lifted, there will be a need for the competent maintenance of fire safety systems/provisions and fire risk assessment work. Fire doors and risk assessments Amthal is working closely with building owners and managers across the UK to deliver the benefits of safer environment This means for those who own or manage residential buildings, will soon be ‘held into account’ if they do not ensure fire safety in their buildings, and the requirements will impact further on costs and resource allocation, for investigating buildings and ensuring compliance. There is a definite sense to be proactive in acceptance of the new impending legislation. But the concern cited amongst building owners is the industry’s ability to undertake the volume of assessments required, given the lack of current lack of specific legislation on specific elements such as fire doors and risk assessments, together with the steep expectations for fire strategy and evacuation plans. Amthal is working closely with building owners and managers across the UK to deliver the benefits of safer environment within a holistic fire safety approach. Working in partnership, means taking the time to understand the implications of the Government’s Fire Safety Bill, alongside the implications of the Building Safety Bill and BSR program. This way, we can ensure responsible persons confidently achieve all operational requirements for the ultimate benefit of residents’ peace of mind.

New government legislation due to come into force in the United Kingdom on July 1st will require electrical installations in privately rented properties to be tested and inspected at least once every 5 years. The Electrical Safety Standards in the Private Rented Sector Regulations (2020) will require landlords to enlist qualified electricians to complete inspections and provide certification to tenants – or face fines of up to £30,000. While the risk of fire can never be entirely eliminated, the new legislation will introduce higher levels of safety and ensure that one of the primary causes of fire – electrical malfunctions – is regularly tested for. There are a number of procedures and regulations in place for when a fire has already started, but this new law will help to reduce the chances of it getting to that point. After all, prevention is the best form of protection. No safety procedure or response plan will ever fully prepare someone for the reality of a fire. However, a comprehensive prevention strategy and use of the latest technologies to quickly detect and respond to a fire can at least reduce the potential risk to both life and property. Defensive detection A fire can spring from many sources. Current standards do a good job of ensuring properties are well equipped to defend against fires created by overcurrent caused by overloads and short circuits. A comprehensive prevention strategy and use of the latest technologies to quickly detect and respond to a fire can at least reduce potential risk However, electrical fires can also result from mistakes made during the installation process, namely loose cabling or aging circuits that will not be detected by overcurrent protection. Indeed, a defective or worn insulation is the cause of 14% of all electrical fires in buildings. The danger of landlords only performing the bare minimum to protect their buildings is that, should a fire start from a source they haven’t accounted for, the loss and disruption to property could be devastating. For maximum protection, individuals need reliable, innovative products that excel beyond the minimum standards to prevent a fire from starting in the first place. The pending legislation will add to this safety from the start. It will require landlords to use qualified electricians when installing, repairing and maintaining systems, benefitting both landlords and tenants by mitigating electrical issues and instilling greater confidence. Protection against insulation faults The risk of cable insulation faults grows over time and the consequences can be severe. Low-intensity arc faults are more likely to occur in humid, dusty environments, causing injury and deadly fires if precautions aren’t taken. Protection against insulation faults within cables can be assured by residual current devices (RCD), which are triggered by earth leakage currents exceeding 300mA. For maximum protection, individuals need reliable, innovative products that excel beyond the minimum standards to prevent a fire from starting Additionally, final circuits in critical locations (as recommended in IEC 60364), should be protected by an arc fault detection device (AFDD). This is a circuit breaker that automatically cuts off the electricity supply when it detects an arc fault in the circuit. By immediately stopping the supply, AFDDs stop arc faults from reaching temperatures where fires can break out. As well as ensuring that private tenants feel more safe and secure, the new legislation represents an opportunity for electricians to secure more work and develop their skills. Going forward, as the demand for electricians in the private rented sector rises, we expect to see greater opportunity for electrical engineers to win long running contracts with landlords and property managers. Fire may be a risk, but it is not unavoidable. This new legislation promises greater peace of mind for private tenants by ensuring that electrical standards are met and hazards reduced. With expert knowledge and the correct approach to electrical fire prevention, a fire can be extinguished before any damage is done.
