Draka’s Firetuf cable series for the cabling of tunnel systems has grown with the launch of the new Firetuf OFC-LT-SWA fire resistant loose tube cable with steel wire armour. As with all Firetuf cables, Firetuf OFC-LT-SWA has been designed for harsh environments and to ensure fail-safe management of operational systems in tunnels, underground railways and fire alarm systems.

A steel wire armoured, refractory cable, Firetuf OFC-LT-SWA is ideal for heavy duty applications due to its high mechanical strength and pulling tension, plus its resistance to even the most determined rodents. The loose tube cable offers 90 minutes fire resistance thanks to its innovative design with double LSZH (Low Smoke Zero Halogen) sheathing in accordance with IEC standard 60331-25. The number of fibres per cable, from 12 to 144, is unique in the market.

Central Tube Cables

The new Firetuf OFC-LT-SWA is the latest addition to Draka’s portfolio of loose tube cables, which includes non-metallic Firetuf OFC-LT-NM and corrugated steel tape armoured Firetuf OFC-LT-CST. With a maximum number of 144 fibres, all three cable types are unique in the market. All three cable types have been thoroughly tested and approved.

Draka also offers the Firetuf OFC-UT-NM (non-metallic) and Firetuf OFC-UT-CST (steel tape armoured) central tube cables, which are fire resistant

Draka also offers the Firetuf OFC-UT-NM (non-metallic) and Firetuf OFC-UT-CST (steel tape armoured) central tube cables, which have a fire resistance even longer than their loose tube variants – up to 120 minutes. Depending on the design, they are equipped with 2 to 24 fibres.

Tunnel Management

The number of tunnels and subways are increasing from year to year in a bid to better manage our traffic infrastructure, but present challenges when it comes to emergency situations such as accidents or fires. Safety is therefore the central issue in the planning and construction of tunnels," says Tayfun Eren, Product Manager at Draka, Prysmian Group.

"The operational systems for tunnel management must be fail-safe around the clock. This requires safe and reliable cabling. Our high-quality Firetuf cable series are optimized for applications in tunnel operation such as fire detection, fire alarm systems, light and ventilation control and escape route systems and guarantee a highly available cable infrastructure.”

A New Normal: California Wildfires Deadliest In History
A New Normal: California Wildfires Deadliest In History

The immense scope and scale of this month’s California wildfires are a timely reminder of a “new normal” that includes a catastrophic toll in human tragedy and presents new challenges for fire service professionals. Some have pointed to the increased frequency of wildfires as a consequence of global warming, and the resulting higher temperatures, less humidity and changing wind and rainfall patterns. President Trump has blamed “poor forest management” (an assertion the president of California Professional Firefighters has called “dangerously wrong.”) Other theories include population shifts and the proximity of residences near wildlands. There has been talk of a need for better long-term fire prevention. But whatever the cause, the results are eye-opening. Historically, all but one of California’s biggest-ever wildfires have occurred in the last 10 years Rapid Increase In Wildfires In California California’s Camp Fire has been called the deadliest wildfire in the state’s history. Fast-moving and unpredictable, the fire totally destroyed the town of Paradise. At the same time, the Woolsey Fire continued for 10 days and consumed an estimated 96,949 acres in Los Angeles and Ventura counties. Historically, all but one of California’s biggest-ever wildfires have occurred in the last 10 years, whether measured in terms of area impacted, loss of life or damage to property, all suggesting a troubling acceleration. In fact, an increase in wildfires is causing destruction around the world. Firefighters Combating Wildfires Effectively For firefighters, the experience and environment have been compared to working in a war zone, reflected by terms such as “aerial assaults” and “boots on the ground.” Burned-out cars on the side of the road, residents fleeing from their homes and whole areas totally annihilated reflect a level of destruction that is unusual in a peaceful society. Tent cities of displaced residents are reminiscent of war refugees. For the recent California fires, firefighter teams traveled from 17 states to battle the wildfires The California wildfires also bring out the best in humanity. There are tales of neighbor helping neighbor and examples of heroism among residents and firefighters, who also share a feeling of brotherhood and kinship forged in extremely adverse conditions. It’s a job that demands bravery and resilience. For the recent California fires, firefighter teams traveled from 17 states to battle the wildfires, from as far away as Alaska and Georgia. There were around 200 firefighters from Texas, 300 from Oregon, and 144 from Arizona among the extra manpower deployed to fight the fires. Protecting Firefighters From Wildfire Danger Fighting wildfires requires a specific approach and offers new challenges. Water can be difficult to find in an already drought-ridden state. Fires that spring up in wooded areas present difficult terrain for fire-fighting vehicles. Higher heat and smoke levels challenge the best methods of protecting firefighters from injury. As the accelerated pace and larger scale of wildfires continue, the fire service will need to expand its strategies, and fire equipment industry will need to enhance its toolbox to meet tomorrow’s continuing horrific realities. If there is a lesson in this month’s wildfires in California, perhaps it is this: More to come.

In Search Of Best Practices As Grenfell Tower’s Impact Reverberates
In Search Of Best Practices As Grenfell Tower’s Impact Reverberates

From a dozen or more perspectives, the tragic fire at London’s Grenfell Tower was a wakeup call. The shear scope of the tragedy – 72 deaths, 70 injuries in the worst United Kingdom residential fire since World War II – is a stark reminder of the importance of fire prevention, and the catastrophic consequences of its failure. There are additional lessons to be learned from the fire service response to the blaze, which burned for 60 hours and involved 250 London Fire Brigade firefighters and 70 fire engines from stations across London. A stark reminder of the importance of fire prevention, and the catastrophic consequences of its failure In short, the Grenfell fire is the kind of colossal event that shakes aside any complacency that stems from a decades-long trend of decreasing deaths from fire. It takes a tragedy of such monumental proportions to get the full attention of government, regulators, fire professionals, and the general public. In the aftermath of the tragedy, the challenge is to focus that attention in ways that can have a real impact on preventing future tragedies.   Building Regulations And Designs  A torrent of questions and second-guessing have emerged from the Grenfell experience. How should building regulations change, including the use of aluminum composite material panels that contributed to the rapid spread of the fire? What about building designs? Grenfell Tower had one central stairwell and one exit. Are more sprinkler systems needed in residential buildings, and what obstacles must be overcome to make it happen? Related to the response to the fire, how did officials who advised residents to “stay put” for two hours as the fire was spreading contribute to the death toll? How should practices change, given that “stay put” is often the advice to residents in a high-rise building fire likely to be easily contained? Every action taken in response to the fire is being scrutinised. Will useful new best practices emerge? Are more sprinkler systems needed in residential buildings, and what obstacles must be overcome to make it happen? Sufficiency of firefighting equipment is another concern. In the Grenfell fire, how was the firefighting effort impacted when a tall ladder did not arrive for more than 30 minutes? What was the role of low water pressure? Were there problems with radio communication?   The Grenfell Tower Inquiry, ordered by Prime Minister Theresa May on the day after the fire, is examining every detail. The inquiry’s chairman has promised that “no stone will be left unturned.” Meanwhile, it behooves all of us to ponder what lessons we can learn from the tragedy, and to ask how we can apply those lessons to prevent future tragedies.

Virtual Reality Emerging As A Training Tool In The Fire Service
Virtual Reality Emerging As A Training Tool In The Fire Service

The dangers of firefighting make it unfriendly to the concept of the learning curve. Before they put their lives on the line, firefighters should have knowledge and experience. But gaining knowledge and experience in the firefighting environment presents its own dangers. Virtual reality (VR) is an emerging tool for training in the fire service. Recreating the firefighting experience realistically in a virtual world is a useful – and safer – alternative to on-the-job training. It is also less expensive than some other training options, such as recreation of realistic fire rescue scenarios.  “For a situation when someone’s life would be in danger, a virtual reality experience can enable them to practice in the safety of their own environments,” says Michael Schreiner, Senior Director of Content for Target Solutions, which is developing VR training for firefighters. “In real life, the building would be on fire and they would have to make life-or-death decisions. With virtual reality, firefighters can make a mistake about how to attack a fire without putting themselves in danger.”With virtual reality, firefighters can make a mistake about how to attack a fire without putting themselves in danger.” Virtual Reality Firefighter Training Target Solutions, a brand of Vector Solutions, Tampa, Florida, has partnered with Pasco County (Fla.) Fire Rescue to develop a lifelike 360-degree VR “smoke reading” training course. Creating the course involved a 360-degree Virtual Reality video shoot using drone technology to film actual firefighters training in real-life simulations. The video was created with expert help from consultants and field insights from subject matter experts, fire service instructors, and paramedics. Learners using the course wear VR goggles and are immersed in a virtual environment where they will receive instruction on how to read smoke and to decide how to attack a fire based on what the smoke tells them. Reading smoke involves judging the color, volume, density and rate of rise. For example, the seat of a fire tends to produce smoke that is thick and dark and has a high rate of rise; in contrast, smoke elsewhere is a burning building might be light and wispy. Firefighters have to make split-second decisions based on the appearance of smoke, and deciding wrong can have dire consequences. Another benefit of virtual reality in firefighter training is lower costs Making Better Decisions The 12-minute-or-so smoke reading “micro-course” uses a story-based approach to emphasize the emotional elements of decision-making. Schreiner says people learn best when emotions are tied into the learning. Elements of the training scenario include exposition, rising action, a crisis and a resolution. Unrelenting “heartbeat” sounds promote a sense of urgency. The course then evaluates whether a learner made the right decision. The course can be practiced over and over. The idea is for firefighters to develop “muscle memory” to make better decisions under pressure in a real fire rescue situation. Vector Solutions chose shooting a video for a real-world effect over computer-generated graphics, which are more expensive but less realistic. For the video training, smoke graphic effects were added in post-production. Lower Training Costs The idea is for firefighters to develop “muscle memory” to make better decisions under pressure in a real situation Another benefit of virtual reality in firefighter training is lower costs. The training session used to shoot the 360-degree video cost around $20,000, which is typical of similar training exercises. Mobilizing a ladder truck, two fire trucks, a fire rescue truck and commander’s vehicles are all part of the costs, as are the costs (including overtime) of 13 firefighters taking part in the exercise. VR is a relatively new learning tool, and Schreiner says feedback from the market will make it clear how effective it is. “We can immerse a person in a situation and it’s a safe environment, but we have to let our learners tell us how effective it is,” he says. “We will get feedback from learners and training administration. It’s another tool in the toolbox, but it will not totally replace real-life training.” VR Training For Dangerous Professions Schreiner says VR is a huge training opportunity for any type of dangerous profession, whether construction workers operating on scaffolding, or educators in an active shooter situation. “Where safety is a risk, VR will really start taking off,” he says. Almost 6,000 clients across the United States use Target Solutions training products, including courses that are specific to the fire service, such as "Cancer Related Risks of Firefighting."
