Fire Suppression Fluids And Gases, The Future Of Marine Fire Safety
Fire Suppression Fluids And Gases, The Future Of Marine Fire Safety

The original fire suppression agent has always been, of course, water. In the age of sail, it was ideal. Not so with the advent of the combustion engine, however. When applied to burning petroleum, the fire spreads. It also simply destroys electronics. Carbon dioxide (CO2) and Halon derivatives were the first widely used commercial fire suppression solutions, gaining popularity in the 1950s and '60s. Unlike water, they were highly effective, electrically non-conductive and didn't leave any residue. As compressed gases, storage wasn't a major issue. Unfortunately, Halon was found to be a high ozone depleting chemical; as a result, production was banned in 1990. Evolution Of Fire Suppression Systems Ideal for marine applications, HFC227 is fast, effective and clean With the sunsetting of Halon and the search for alternatives, CO2 gained prominence. However, it has three significant drawbacks: it's a greenhouse gas, requires a large number of cylinders and is potentially fatal if breathed at design concentrations. In the 1990s, HFCs rose to dominance as a fire suppression solution. Ideal for marine applications, HFC227 is fast, effective and clean. Like Halon and CO2, however, it's a greenhouse gas and contributes to global warming. Discharging an average-sized cylinder of HFC227 has the same CO2 equivalent as driving a car 268,760 kilometers. This is why it is being eliminated as part of a phased-down mandate from the EU, and restricted or taxed by various countries such as Australia and Norway. It is expected that similar legislation will begin to affect Canada and US-flagged vessels. Environmental Profile Of HFCs In 2002, 3M introduced Novec™ 1230 Fire Protection Fluid. It offers a number of important advantages over other clean agents in marine fire suppression applications. It has low acute toxicity and high extinguishing efficiency. This gives it a wide margin of safety compared to other chemical clean agents such as HFC227. A fluid, it vaporizes rapidly during discharge, is non-corrosive, non-conductive and leaves no residue. It is, importantly, a long-term, sustainable solution with virtually zero global warming potential, e.g., it has an atmospheric life of about a week versus HFC227's 34 years. So confident is 3M of its product, it offers its BlueSkySM Warranty; if it is ever banned or restricted from use due to its environmental properties, the company will refund the cost of the fluid. Unlike CO2, a gas, Novec 1230 fluid can be flown to the vessel or platform allowing less downtime waiting for supplies to arrive by ground For the marine and offshore oil and gas industries, Novec 1230 fluid offers distinct advantages. Because it's a fluid, recharging is simple. Unlike CO2, a gas, it can be flown to the vessel or platform. This means less downtime waiting for supplies to arrive by ground. It also takes up significantly less space. Recently, Sea-Fire Europe ceased distribution of HFC227. The move was strategic and ethical, given the environmental profile of HFCs. Novec 1230 Fluid For Recreational Marine Market With the phase-down of HFCs, supplies are running out. This means in the immediate future there will be a serious inability to service systems. Also, with shortages beginning, costs are rising, making the switch to Novec 1230 fluid a smart move financially. While 3M will obviously benefit from this, the real winner here is our planet and the people we share it with" Sea-Fire recognizes that it may lose business in the short term as boat and shipbuilders continue to choose HFC-based fire systems strictly based on cost alone. But, ultimately, eliminating the use of hydrofluorocarbons is the right thing to do for the marine industry as a whole. As the first manufacturer to introduce Novec 1230 fluid into the recreational marine market in 2012, Sea-Fire is fully prepared for the phase-out of HFCs. Benefitting The Marine Industry "As a corporation, 3M is committed to improving every life," said David Olds, 3M account executive for fire suppression applications. "Sea-Fire Europe made a difficult decision when announcing it would cease distribution of HFC227. While 3M will obviously benefit from this, the real winner here is our planet and the people we share it with." Sea-Fire Marine has long held the belief that it is in the business of protecting people and property at sea. With its recent declaration that its master European distributor Sea-Fire Europe is ending distribution of HFC-based fire suppression fluids, it can add the environment to its list.

How Targeted Suppression Stops Fires At The Source
How Targeted Suppression Stops Fires At The Source

While whole room protection – sprinklers or gas systems – is a common choice, there is an argument for thinking smaller; taking fire detection and suppression down to the equipment, enclosures and even the components where a fire is most likely to start. Traditional Fire Suppression Methods A traditional water-based sprinkler system is the most common form of fire protection found in commercial and industrial buildings. They offer reasonable cost, large area protection for entire facilities, safeguarding the structure and personnel by limiting the spread and impact of a fire. Every square foot of the protected area is covered equally regardless of the contents of the space, whether it’s an empty floor or an object with an increased risk of fire. Sprinklers aren’t always the most appropriate choice. Not all fires are extinguished by water of course, and in some cases, water damage can be just as harmful or even more so than the fire. They are an impractical choice for instance for facilities housing anything electrical, such as data centres and server rooms. There is also the risk of accidental activation, with an estimated cost of up to $1,000 for every minute they are left running. Water damage can be just as harmful or even more so than any fire, so sprinklers may not be appropriate Targeted Supplementary Fire Suppression An alternative method to protect whole server rooms and data centres is gas fire suppression, which either suppresses the fire by displacing oxygen (inert) or by using a form of cooling mechanism (chemical/synthetic). These aren’t without risk; in the case of inert gas, oxygen is reduced to less than 15% to suffocate the fire, but must be kept above 12% to avoid endangering the lives of personnel. Similarly, clean agent gas can be toxic in high doses. There are smaller, focused systems that give the option of highly targeted supplementary fire suppression within fire risk areas. Installing a system directly into the areas most at risk, means that fires can be put out before they take hold and cause serious damage. Both sprinkler and gas systems can contain a fire, but micro-environment or closed space systems are completely automatic, detecting and suppressing the fire so rapidly that activating a sprinkler or gas total flooding system often isn’t necessary. The most popular enclosure fire suppression systems achieve this though the use of a flexible and durable polymer tubing that is routed easily through the tightest spaces. The tubing is extremely sensitive to heat and, because it can be placed so close to potential failure points, detects it and releases the fire suppression agent up to ten times faster than traditional systems. An airline was forced to cancel over 2,000 flights after a “small fire” in one of its data centers Cost-Effective Fire Protection Highly customizable, small enclosure fire suppression is specifically designed to protect business critical spaces and equipment. It is typically used inside machinery like CNC machines, mobile equipment like forklifts and inside server rooms and electrical cabinetry but is suitable for any hazard that’s considered to have an elevated fire risk. Some may question the need or cost-effectiveness of protecting micro-environments. However, examples abound of where fires that have started at component level have gone on to cause damage of the highest magnitude, and the cost of downtime can be crippling to many time-sensitive facilities and processes. An airline was forced to cancel over 2,000 flights in August 2016 when what was described as a “small fire” in one of its data centers ultimately led to a computer outage. The cost of that small fire, and the domino effect that quickly escalated from it, has since been announced as $150m. Admittedly that number is unusually high - the average cost of a data centre outage today is estimated at a more conservative $730,000 – but this is still an expense businesses can ill afford. Preventing Major Losses Staying with the transport industry, newer metros systems have redundant systems in place to prevent interruptions. However, older metro lines, such as the one in New York City, have experienced electrical fires that started small, but grew to such a magnitude that service was affected for months.Older metro lines, such as New York City's, have experience electrical fires that start small but grew exponentially A wind energy customer experienced a fire in a turbine converter cabinet. The loss of the cabinet was valued at over $200,000 and disabled the turbine for six weeks. Following investment in fire suppression systems inside the electrical cabinet, a subsequent fire was detected and suppressed before major damage could be caused. The cost on this occasion was therefore limited to a $25,000 component and downtime was less than two days.Equally - happily - there are also many instances where the installation of small enclosure fire suppression has prevented disaster. In the manufacturing world, CNC machines are valued at hundreds of thousands of dollars and need to be constantly operational to justify the investment. Oil coolant used in the machines can create a flash fire in an instant due to failed components or programming errors. The fact that many of these facilities are run ‘lights out’ with no personnel present further exacerbates the risk. If a fire is not dealt with immediately, the machine will be destroyed; sprinklers don’t react quickly enough for this scenario and would be ineffective. Ensuring Business Continuity One such flash fire occurred inside a protected CNC machine at a machine shop in Iowa. The polymer tubing ruptured within a fraction of a second, releasing the suppression agent and extinguishing the flames. The machine was undamaged and was operational again with a few hours. Contrast this to a previous fire at the same facility in an unprotected machine; it was out of operation for 4 days, costing the business thousands of dollars in downtime In short, fire protection is an essential element of our industrial and commercial environments to ensure both safety and business continuity. However, the nature of that protection is changing, as capacity increases to cost-effectively protect specific areas where fires are most likely to start. Risk mitigation analysis needs to look beyond what has been accepted in the past and find ways to further limit the impact of a small fire using this next level of protection. The benefits can really have a positive effect on the bottom line in the event of fire.

Intersec Sponsors Safety Design In Buildings Conference 2019 Which Hosts Debates On Safety Standards And Built Environment Practices
Intersec Sponsors Safety Design In Buildings Conference 2019 Which Hosts Debates On Safety Standards And Built Environment Practices

The global debate on building cladding, which has soared up the international safety agenda in the wake of London’s Grenfell Tower disaster which claimed 74 lives and left another 70 injured, arrives in Doha this month. Building cladding is a key feature of the Safety Design in Buildings Conference (SDiB), which runs on 16 October at The Business Park of the Crowne Plaza, Doha. The conference will feature 11 regional and international experts as speakers. Insight On Improved Protection The spread of the June 2017 fire, which arose from a refrigerator electrical fault and ripped through the 24-storey Grenfell Tower, was largely exacerbated by the building’s flammable exterior cladding. The annual SDiB campaign is a GCC-wide initiative to debate safety standards and practices “In a region dominated by high rise structures, it’s not surprising that the local industry is keen to learn lessons from Grenfell,” said Andreas Rex, show director for Intersec, the world’s pioneer trade fair for Security, Safety & Fire Protection which is SDiB’s Founding Sponsor. The annual SDiB campaign is a GCC-wide initiative to debate safety standards and practices in the built environment. “Like Intersec, SDiB is essential for sharing insight on improved protection of people and assets in the Gulf.” Examine Retrofitting For Fire Safety The SDiB Doha conference will bring leading fire safety consultants, architects, engineers and testing experts together with safety systems suppliers to explore industry standards updates and debate best practice solutions. The agenda will examine retrofitting for fire safety, how to best involve design teams to mitigate fire safety risks, façade fire compartmentation and how mega infrastructure projects can meet international safety standards. Achieving Safety Compliance On Existing Buildings Sreenivas Narayanan, General Manager – Middle East and Asia Pacific of the UK’s Siderise Insulation Limited will outline strategies for achieving safety compliance on existing buildings. His presentation will discuss the need for safety compliance on existing structures and buildings which have been in use for some time. Fire and life safety systems are commonly engineered and designed based on the operational effectiveness" “The issues surrounding the cladding on a project has been a key discussion globally,” he explained. “It's important for all stakeholders involved in a project to understand what the requirements are and how to overcome the challenges. The global façade industry is keen to incorporate the best practice and I would be sharing from my recent interactions to support the local market.” Abilities To Maintain And Commission Fire Cristina Perez Domper, Regional Operations Manager – Product Testing and Certification Building & Construction of Britain’s Intertek will further the debate abilities to maintain and commission fire and life safety systems in high rise tower clusters – capabilities which she asserts are all too often neglected. “Fire and life safety systems are commonly engineered and designed based on the operational effectiveness,” she explains. “What is equally important but often overlooked is the ease of maintenance, testing and even commissioning. A fire safety system that cannot be, or is difficult to maintain or to test, will result in it not being tested or maintained which in turn will lead to it not working properly.” Maintenance And Testing Domper says preventative action is key to a comprehensive fire safety strategy through a building’s lifespan. “According to the National Fire Protection Association statistics, nearly 30% of fires in non-sprinkled facilities spread beyond the room of origin. To minimize this, preventative action must be taken to reduce the effects of fire on a facility, business continuity and life safety,” she advises. Fire safety installation that can’t be maintained will eventually end up in non-working fire safety systems" But Peter Van Gorp, Director of Fire and Life Safety of the USA’s AESG says lessons have been learnt and are being incorporated into new builds, though more attention needs to be placed on maintenance and testing. Maintainability Aspect Of Fire Safety Systems “While I used to see blatant mistakes in fire safety system design related issues in the past, I don’t see those that often anymore in newly constructed buildings. What I do still see is mistakes with regard to ease of maintenance and ease of testing. “These aspects are not only overlooked but often completely ignored. Fire safety installation that can’t be tested or maintained or are difficult to test or maintain will eventually end up in non-working fire safety systems like any other installation or system,” he warns. “I hope that my presentation will move authorities, designers, contractors and anybody else involved to give the maintainability aspect of fire safety systems the attention it deserves.” Protecting Major Events Through Stadium Security The presentation will highlight the key requirements for delivering a safe, and secure stadia" Safety for mega projects and events is also on the Doha agenda, which is essential to Qatar as it gears up to host the 2022 FIFA World Cup and has huge major event ambitions. Andrew Cooke, Director Security Operations of Doha-based International Centre for Sport Security will outline ways of protecting major events through stadium security design, which he says, has significant bottom-line implications. “By integrating security right from the beginning of the design phase for venues, organizers can make significant savings by identifying potential threats at an early stage in the process and thus preventing expensive rework, delays, penalties and incorrect use of resources and materials later. The presentation will highlight the key requirements for delivering a safe, and secure stadia.” Testing All Components Of A Fire Strategy Having gained extensive experience within the fire sector and witnessing devastating effects of fire first-hand, Peter Stephenson, Business Development Manager at Warringtonfire emphasizes the importance of sharing lessons learnt to mitigate fire hazards. Validating and testing all components of a fire strategy is vital to ensure the safety of all persons" As building assurance is extremely important, Stephenson highlighted Warringtonfire’s involvement in Doha Metro, one of the key infrastructure projects linked to the FIFA World Cup 2022 hosted in Qatar “Validating and testing all components of a fire strategy is vital to ensure the safety of all persons using or working on the infrastructure.” Tests, Inspections, Certifications “SDiB provides a platform to bring industry professionals together to learn and share experiences which ultimately enhance fire safety within the region. At Warringtonfire, we value the safety and wellbeing of our employees and consider it a top priority. This belief is reflected in our tests, inspections, certifications and consultancy services,” added Stephenson. “The key take-away at SDiB is the importance of building assurance, emphasizing that Warringtonfire, with its depth of experience and industry experts, is the first choice as a trusted partner for all fire and life safety requirements.” Digital ‘Passive’ Fire Protection Delegates will also hear how digital tools can now automate fire safety. David Black, Director, Middle East Operations of the GCC’s Joule Group says despite laws and regulations, human error remains a daily risk because ‘passive assets’ - non-digital fire systems - are not prioritized. The emergence of passive protection is one factor behind the expansion of the show’s Fire and Rescue section" “We need to have more transparency on how passive fire assets are managed and checked building to building. This can be achieved through the use of digital platforms,” he said. Digital ‘passive’ fire protection is also high on the agenda for Intersec, which will run at the Dubai World Trade Centre from 19-21 January. Intersec’s Growing Sections “The emergence of passive protection is one factor behind the expansion of the show’s Fire and Rescue section, which is now one of Intersec’s fastest growing sections with more than 450 exhibitors and includes industry leaders such as NAFFCO, Honeywell, Komtes, Hochiki, Draeger, ATEIS, and Thomas Bell-Wright International,” explained Rex. “Additionally, the show will feature a Safety Design in Buildings Pavilion dedicated to Fire Safety in the building materials industry.” The next SDiB conference will run in Abu Dhabi on December 12th.
