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 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.

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.

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.

Equinor Chooses VIKING Norsafe E-GES 52 Electric Free-Fall Lifeboats For The Njord A Platform

VIKING has secured a contract from Kværner AS to deliver three VIKING Norsafe E-GES 52 electric free-fall lifeboats and compatible davits, in a significant advance for electric propulsion. The contract, part of the upgrade of Equinor’s Njord A platform in the Norwegian Sea, initially called for diesel-powered lifeboats but has been amended to specify VIKING Norsafe E-GES 52 units based on performance, assured availability and lower maintenance requirements. “Developing this ground-breaking electric freefall lifeboat has been a great team effort and I would like to congratulate our designers, engineers and partners in turning this concept into reality,” said Dag Songedal, MD VIKING Norsafe Boats & Davits. Waterproof cases The electric lifeboat is powered by 3x25 kWh batteries contained in robust, waterproof cases with their own fire extinguishing systems and an electric motor complete with gearbox and ventilation system. VIKING is delighted to work in partnership with Equinor in a step forward for battery power  Mr. Songedal says VIKING is delighted to work in partnership with Equinor in a step forward for battery power that will also result in enhanced maritime safety. The VIKING Norsafe E-GES performs the launch phase of an evacuation at a higher sprint speed than lifeboats featuring diesel propulsion, thereby transporting evacuees more quickly and safely away from the platform in the case of an emergency, he points out. Remote monitoring capabilities The significant long-term cost savings achieved through reduced maintenance and remote monitoring capabilities are also incredibly valuable for offshore operators, says Mr. Songedal. Other benefits include better onboard comfort due to the absence of the exhaust fumes, heat, noise and vibration caused by diesel engines. Built in compliance with DNV GL-ST-E406, the VIKING Norsafe E-GES development is in the final test phase at VIKING’s direct ocean-access premises in Arendal, Norway, with full production ready in time to meet the agreed delivery date to the Njord A platform.
