Draeger Fire Detectors(27)
The Dräger Flame 5000 is a colour imaging based flame detector. Using advanced digital signal processing and software algorithms, it can process the live video image and interpret the characteristics of a flame. Subsequently the detector is virtually immune to any potential false alarm sources including hot processes, flare reflections and hot CO2 emissions.Each detector performs two functions; flame detection and CCTV surveillance. This reduces maintenance and installation costs, and the surveillance aspect of the detector eliminates the requirement to dispatch operators to investigate alarms as live video images can be directly viewed from the control room. This reduces the risk to operators and can improve response times.The detector is capable of detecting a 0.1m2 gasoline fire at 44 metres, and an extended operating temperature of -60° C to +85° C makes the Draeger Flame 5000 suitable for a wide range of applications. Advanced optical verification is designed to check the detector window for contamination and to ensure that the detectors field of view is not restricted by an object placed directly in front of the window.The Dräger Flame 5000 is certified with Worldwide Approvals including ATEX, IEC Ex, and FM Listing. The detector is also SIL 2 verified.Add to Compare

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.
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 introduced a variety of unique challenges for many industries around the world. Not surprisingly, the fire detection industry was not immune to all of those challenges. However, as much of the global community defined our manufacturing and installing peers as “essential” or “critical” it required us, as an industry, to adapt so we could continue to service our customers with our products and services. Many regions around the world are experiencing significant demand for temporary detection systems. This demand is almost universally driven by an increase in education, awareness, and enforcement. While this is a global shift, our company has experienced a large demand in our own backyard. Within the United States, this is being driven by the adoption and enforcement of NFPA 241. NFPA is the Standard for Safeguarding Construction, Alteration, and Demolition Operations. NFPA 241 has been a “concept” since 1930 and the official text was finally adopted by the NFPA in 1933. As with all standards, it has progressed over the years to accommodate changes in technology as well as safety awareness. Fire safety awareness While general safety awareness on construction sites has always been consistently high, fire safety awareness has significantly increased within the last 5 years. Nuisance alarms negatively consume first responder bandwidth Typically, new, or increased regulation within our industry occurs after a single devastating event or several significant events. In this particular case, it was a combination of both. On a national level, fires on construction sites were reaching dangerous and unacceptable levels and becoming so widespread that enforcement of this standard became a priority in several states. Need for accurate and timely fire detection According to a report released by Richard Campbell of the NFPA in February of 2020 titled Fire In Structures under Construction or Renovation, “the estimated number of fires in structures under construction has increased since 2014 after declining between 2008 and 2010” further creating awareness. For the last few years, the focus of many local AHJ’s (authority having jurisdiction) was on new and active worksites or renovation projects. With the changes imposed by the COVID-19 pandemic today, many non-essential industries have either shut down or had their operations significantly reduced. This means the need for a functioning detection system is more critical now than ever as many facilities remain idle or continue to operate with reduced personnel. Detecting fires quickly and accurately gives our first responders the best chance of saving a person or facility. Conversely, having any “detection system” is often not good enough. Nuisance alarms negatively consume first responder bandwidth, possibly removing an engine or fire company from a genuine event. Temporary fire detection In an article by The Boston Globe, Easthampton Fire Chief David Mottor, president of the Fire Chiefs Association of Massachusetts said “Ninety percent of these buildings go up every day and nothing happens. It’s during construction before the sprinkler system is activated when they are most dangerous.” Globally, we have seen four approaches to temporary detection for both construction and renovation sites. We will quickly discuss the advantages and disadvantages below: Using 24/7 fire watch Utilizing local first responders or other authorized/trained personnel to offer 24/7 fire watch requires a person or team of people to be onsite 24 hours a day, 7 days a week to be physically looking for fires. Advantage: Someone is always on site, actively viewing and patrolling the facility. Disadvantage: Maintaining a 24/7 fire watch can be expensive, further the person or team can only see/find fires in proximity to them as they continue to move about a facility. Using digital linear heat detection Digital linear heat detection is a fixed temperature detector that is constructed using a twisted pair of metal conductors that are separated by a heat sensitive polymer. When the ambient temperature meets or exceeds the detector’s fixed temperature the polymers melt, and the detector shorts out resulting in an alarm. Advantages: Detector can be easily installed at a new construction site or a facility being renovated. The technology is a low profile, non-intrusive and cost-effective form of detection. This automatic initiating device is immune to environmental conditions. Protectowire FireSystems offers Confirmed Temperature Initiation technology (mechanical damage does not cause a false alarm). Disadvantages: Detector can be mechanically damaged during normal worksite operation. If you are unsure, be sure to check with the local AHJ or call your insurance provider Using wireless spot detectors There are a few companies on the market that offer wireless spot detectors that can be networked together. Advantage: Typically, this technology uses a mesh network of detectors. The detectors and their bases are battery operated and can be moved or placed per worksite requirements. Disadvantage: This technology can be expensive. Physical barriers on the construction site may hinder mesh network operation requiring the purchase of additional wireless units. Many wireless technology providers focus on smoke detection. Smoke detectors are often not ideal for the harsh environments associated with construction (dust, temperature changes, etc.). Using a hybrid approach This involves using wireless nodes to supervise linear heat detection. Most manufacturers of the wireless systems offer a wireless node that can accept a third-party initiating device. Advantage: Wireless nodes can be placed anywhere, and linear heat detection technology can withstand the harsh construction environment. Disadvantage: Wireless node battery life can be reduced when using a third-party device. Less cost-effective approach. Solution for Facilities While each of the approaches listed above has its own advantages and disadvantages, you must always consider what is best for your facility. If you are unsure, be sure to check with the local AHJ or call your insurance provider. Established in 1938, Protectowire FireSystems is the global manufacturer of Linear Heat Detection Systems. The Company has been manufacturing in the United States for the past 80 years and counting. Protectowire is dedicated to delivering products designed, engineered, manufactured, and tested with a high degree of performance, reliability, and quality. As one of the manufacturers in the fire protection industry, Protectowire has the experience and knowledge needed to meet the ever-increasing detection challenges of the special hazard and commercial industries.
Dräger, a pioneer in medical and safety technology, is launching its ‘Health for the Firefighter’ campaign to support fire services in driving the cultural changes that are required to protect firefighter health. Impact of exposure The launch follows a survey of UK firefighters that found considerable concern over the impact of exposure to contaminants on long-term health. Some 84% admitted they were concerned about the risk of cancer – a disease highlighted in some scientific reports to be the cause of death within the service. The International Association of Firefighters (IAFF) reports that nearly two out of three (61%) firefighter line-of-duty deaths between 2002 and 2017 were caused by cancer. Embedded carcinogens in any equipment can easily be absorbed by the men and women using it. Robust hygiene processes We need to move away from firefighters wearing dirty kit like a badge of honor" The survey by Dräger also found that more than two thirds (68%) of firefighters fear the impact of COVID-19 on their long-term health, a point picked up by Brian Hesler, Consultant and Specialist Advisor at Draeger Safety UK and former Chief Fire Officer for the Northumberland Fire and Rescue Service: “The COVID-19 pandemic, and the ongoing fears over cancer, have highlighted the critical importance of hygiene, and a significant cultural change is required. We need to move away from firefighters wearing dirty kit like a badge of honor that proves their hard work and value, to understanding that clean and well-maintained kit supported by detailed and robust hygiene processes that mitigate every contact with contaminants are essential. One firefighter surveyed said ‘they had always been a bit blasé about invisible contaminants’. This has got to change.” Detailed hygiene processes The Health for the Firefighter campaign will support the fire services in helping to communicate and provide training on the importance of detailed hygiene processes; from the handling and storage of masks and breathing apparatus (BA) equipment through to the subsequent cleaning of the kit after an incident has occurred. It will also provide bespoke workshop solutions that guide the potentially contaminated kit from entering the station, to washing and drying processes through to leaving the station to be used again. In addition to providing detailed advice for manual washing processes including on detergent use and drying techniques, Dräger is the first company in the Emergency Services space to launch specialist BA and mask cleaning equipment and dedicated solutions, including mechanical washing systems that provide complete consistency in washing temperatures, the amount of detergent used, speed and temperature of drying – which can all work together to disinfect contaminants and to protect the longevity of the kit. Mechanical equipment washing However, only 23% said that the pandemic had significantly changed their approach to cleaning equipment Support also encompasses logistical support for installation, the ongoing maintenance of equipment and the quantity of stock required. The survey revealed the most important factors in combating firefighter concerns over contaminants were the cleaning of masks with 97% rating this as very or extremely important, closely followed by the cleaning of BA equipment (95%) and cleaning of PPE (94%). While manual cleaning of equipment is still generally the norm within UK Fire Services, the survey revealed three quarters (75%) believed that mechanical equipment washing would improve their health, and 80% agreed that as a result of the COVID-19 pandemic more emphasis should be placed on cleaning equipment and hygiene control. However, only 23% said that the pandemic had significantly changed their approach to cleaning equipment. Responsibility to innovate solutions “There is obvious concern over cleaning of equipment following the pandemic,” adds Brian. “One surveyed firefighter said ‘they clean to the best of their ability’ – the point is that a person’s ability should not be a factor in the cleaning process.” “Consistency has to be key and manufacturers of medical and safety technology products have a responsibility to innovate solutions that support change. We are not here to tell brigades how to operate, rather to provide a range of solutions that support them and their firefighters’ health.”
In connection with the COVID-19 pandemic, Dräger has received an order from the British government to deliver respiratory protection masks (FFP3). The delivery of the order will start in 2020 and will stretch until the end of 2021. The expected net sales are roughly EUR 100 million. For this purpose, a mask production will be set up in the UK, in the Blyth area of Northumberland. There, Dräger has had a development and production site for respiratory protection technology for firefighters and industry for over 50 years. Production sites in France and the US This is in addition to the existing production network in Sweden and South Africa and the recently decided new production sites in France and the US. The investment in the expansion of production capacities across all five production sites will require a mid-double-digit million euro amount in the 2020 financial year. Certified FFP respiratory protection masks Rainer Klug, Chief Officer of Safety Division at Dräger: "We are very pleased about the major order from the British government. It gives us the opportunity to expand our international production network for FFP masks. With this additional production unit, Dräger will increase volumes quickly and flexibly. Our international production network enables us to react very quickly and specifically to national or local requirements on the one hand, and to cover international requirements in a closely networked and flexible manner on the other. Dräger thus operates a highly responsive manufacturing system for certified FFP respiratory protection masks, with a product design originating from our own development in Germany."
Concentrations of hazardous substances in the ambient air at the workplace should not exceed specified limit values. Monitoring these sometimes very low values is a demanding task. The focus of the Dräger X-act 7000, in combination with the Dräger MicroTubes for different gases and vapors, is to measure carcinogenic and toxic substances in the lower ppb range. Dräger X-act 7000 analysis system The range of gases to be measured is being constantly expanded. The measurement-sensitive system of the X-act 7000 is based on colorimetric chemical sensor technology and measures even the lowest ppb concentrations. It can replace conventional laboratory analysis and delivers exact reliable results directly on site. False-positive measurement results and false alarms can be largely reduced. This saves time and costs and is easy to use. RFID tags applied to Dräger MicroTubes The analyzer is explosion-proof and certified in accordance with ATEX/IECEx for zone 0 The RFID tags applied to the Dräger MicroTubes contain all the calibration data that is valid for the typical period of use of one year. Complex functional tests and manual calibration procedures are no longer necessary. All possible temperature and humidity influences are already taken into account during factory calibration. The analyzer is explosion-proof and certified in accordance with ATEX/IECEx for zone 0. In addition, the system is IP54 protected against dust and splash water. It also meets the requirements of electromagnetic compatibility according to EN 61326-1. Dräger CC Vision software After an automatic self-test, the X-act 7000 analysis system is immediately ready for use. The user controls the measurement task via the 3-button operation unit and the 2.4-inch color display. The measurement result, location and time can be stored in the internal data logger and read out with the Dräger CC Vision software. Power is supplied by five easily replaceable batteries. The battery capacity is sufficient for more than ten hours of measuring and is indicated on the display. The Dräger X-am pump can be adapted to the X-act 7000 by a connecting piece. This makes it possible to measure carcinogenic and toxic substances in the ppb range possible even in inaccessible locations such as canals, ducts or tank facilitates up to a distance of 45 meters. Since the X-am pump also has explosion protection certification for zone 0, it is ideally suited for these applications. The X-act 7000 is exclusively manufactured by Drägerwerk AG & Co. KGaA (Dräger Safety AG & Co. KGaA).
