Dupont CLEAN AGENT SYSTEMS(2)
Clean Agent System products updated recently
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.
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.
DuPont has been a pioneer in fire safety for over 50 years and introduced its Tyvek® FireCurb® Housewrap breather membrane for buildings in 2013. As regulations catch up post Grenfell, and as most fires begin inside buildings, DuPont has since developed an airtight vapor control layer in its high performance AirGuard® range, to offer similarly advanced, non-toxic, fire-resistance with proven efficacy. Now developers, designers and control officers can have confidence in a complete membrane and tape solution for durably enhanced fire safety in both the exterior and interior fabric of a building. While Tyvek® FireCurb® Housewrap forms a weather-protective, vapor-open lining behind ventilated facades, new DuPont™ AirGuard® A2 FR AVCL offers energy-saving, moisture management, improved interior air quality and climatic comfort, together with its added fire-retardant function. Airtightness and vapour control Tyvek® FireCurb® Housewrap utilizes DuPont's patented self-extinguishing technology. Its halogen-free coating limits the propagation of flames and the formation of droplets, while also minimizing smoke.

Suitable for application in any type of building, these robust products offer not only reliable performance, easy installation and full regulatory compliance, but a vital investment in greater safety and peace of mind, both during and after installation.
MSA, DuPont, and the National Volunteer Fire Council (NVFC) have awarded new turnout gear to two additional departments through MSA’s Globe Gear Giveaway. A total of 13 fire departments will each receive four new sets of state of the art turnouts in 2019 to help them increase the safety of their firefighters and safety personals. To be eligible to apply for MSA’s Globe Gear Giveaway awards, fire departments had to fulfill the criteria of being all volunteer or mostly volunteer, serving a population of 25,000 or less, be legally organized in the U.S. or Canada, demonstrate a need for the gear, and be a member of the National Volunteer Fire Council. To help fire departments meet this last requirement, MSA sponsored NVFC memberships for the first 500 applicants. The latest recipients to receive the turnout gear are Salcha (AK) Fire & Rescue and Kenduskeag (ME) Fire Rescue. Salcha (AK) Fire & Rescue While all 35 of the fire department’s first responders have gear, it has been donated from other departments Salcha Fire & Rescue is located about 40 miles south of Fairbanks, AK, next to the Salcha and Tanana Rivers. The fire department prides itself in being ‘professionally staffed by volunteers since 1982’. Volunteers are trained at both Firefighter I and Emergency Medical Technician II, protecting approximately 2,400 people over 350 square miles. A tight budget, along with care and maintenance costs of hand me down equipment and gear, leaves no room to purchase new turnouts for its firefighter crew. While all 35 of the fire department’s first responders have gear, it has been donated from other departments, most of which are over 15 years old. Gear that is over 10 years old is considered non-compliant with recommended safety standards. The Salcha Fire & Rescue department uses this turnout gear for primary response. “Our goal is to provide safe gear for our volunteer responders so that their safety is guaranteed during fire incidents,” said Chief Ernest Misewicz. This donation will help them to achieve that goal. Kenduskeag (ME) Fire Rescue Kenduskeag Fire Rescue protects a population of 1,338 over nearly 17 miles in Penobscot County, ME. Its 11 active volunteers are trained at First Aid/CPR and Basic Firefighter and respond to an estimated 160 calls each year. The department has been striving to improve its operations, ensuring its fleet is equipped properly and operating safely, which leaves no funding to outfit their firefighters with compliant and efficient gear. Only three sets of their gear are less than 10 years old and meet national safety standards. The department strives to ensure the safety of its responders, particularly mitigating cancer risks The department strives to ensure the safety of its responders, particularly mitigating cancer risks by properly cleaning gear after each call. However, this often leaves the department out of service after a fire until the gear is again ready for response. Additionally, the department has had to turn potential recruits away because of the lack of gear and the inability to purchase new gear that will keep them safe on a call. 2019 Globe Gear Giveaway “These four sets of gear will go a long way to cement morale and make the best use of all who apply to our department, ergo creating a more safe and efficient public service,” said Deputy Chief Matthew Nadeau. Additional awards in MSA’s 2019 Globe Gear Giveaway will be made monthly through December. Stay tuned to the NVFC web site, Dispatch newsletter, and Facebook page, as well as the Globe Facebook page, for announcements. The program began in
Wharton Esherick (1878-1970) was an artist who produced paintings, decorative frames, woodcuts, sculpture and furniture. While Esherick’s work is displayed in major American museums and private collections, a large compilation of his work is found in his studio. His studio has been preserved and maintained since his death, enabling visitors to learn more about the artist’s life as well as view his work. With so many valuable artifacts and artwork in one studio, a superior fire protection system became a necessity. In a fire, smoke could permeate the interior of the studio or flames could char Esherick’s masterpieces before a fire department had time to respond or a conventional sprinkler system would activate. Ionization-Based smoke detector The Wharton Esherick Board decided on a Fike ECARO-25 clean agent fire suppression system with DuPont FE-25After investigating fire suppression system alternatives, the Wharton Esherick Board decided on a Fike ECARO-25 clean agent fire suppression system with DuPont FE-25. The ECARO-25 system is activated by an ionization-based smoke detector that sounds an alarm and reports the first indicators of smoke. Small pressurized tanks of FE-25 installed in closets throughout the studio eliminated the need for an extensive piping system, greatly reducing the cost of installation. Board member Peter Esherick explains the benefit of using the ECARO-25 system, “We considered a common sprinkler system and determined a way to run the vast array of piping, so that it would be mostly invisible. But the system would require a large, separate water line, and would only active if flames heated the ceiling and the building filled with smoke. “Additionally, if activated, water could damage much of the artwork and interior materials. The ECARO-25 system provided us with a viable alternative that met our protection needs and preserved our museum space by avoiding an unsightly installation.” Keeping artwork and Treasures Safe An ECARO-25 clean agent fire suppression system is an excellent choice for applications where release of water, dry chemicals or carbon dioxide can cause collateral damage to irreplaceable museum assets. Thanks to this installation, the Wharton Esherick Studio treasures are safe for future generations to enjoy. Critical Project Success Factors: Selection of an ECARO-25 system allowed for maximum protection from fire and water damage for these unique museum pieces. The necessity for preserving the unique appearance of the studio was accomplished with a unique, cost-effective installation of multiple small tanks and minimal piping. ECARO-25 is also safe for use in occupied spaces, leaves no residue and is an environmentally acceptable alternative to Halon.
