The Sinteso system evaluates each situation minute by minute and takes decisions on complex criteria to ensure a safe environment

Sinteso fire detection system features advanced intelligence which delivers high level of protection against all types of fire hazards

The cost, risk to lives and drain on firefighting resources led the London Fire Brigade (LFB) to announce a stringent new rule which came into effect last year. Organisations are now being fined if they have more than nine false alarm call-outs in a year. The LFB states that despite a 7.3% drop in the number of call-outs after the introduction of the charge, it is still responding to one every fifteen minutes on average.

Call-outs caused by badly maintained systems

Hospitals are among the most prolific offenders with some being visited several times every week by the LFB. The NHS now faces a six figure bill in London for 2014 due to unwanted alarm alerts automatically triggering calls to the emergency services. Most of the call-outs were caused by badly maintained systems, or burnt toast, steam and dust.

Tony O'Brien, head of sales for Siemens Building Technologies Solution and Service Portfolio explains: "These false call outs not only impact the NHS financially, but are a public safety issue. When alarms go off repeatedly, there is a tendency for people to ignore them. In the case of a real fire, complacency could put lives at risk.”

Poor technology leading to unwanted alarms

"Fire detection systems simply should not cause unwanted alarms; if an organisation suffers from excessive false alarms, the root cause is either poor technology, or poor service and maintenance support. Hospitals have the added pressure and responsibility to protect sick, infirm and immobile patients when they are at their most vulnerable.”

"A false alarm is referred to as an ‘unwanted fire signal’ as soon as the fire service is summoned. There is a need to properly educate hospital building and facilities managers about the benefits of the right technology to minimise unwanted alarms and how to properly maintain their fire alarm systems.

“We work with hospitals, as we do with other organisations, to choose and apply the correct fire detectors for the location and application; this alone reduces the chances of an unwanted alarm from the detector itself. It is the responsibility of fire alarm companies to not only install and maintain the technology but also to advice on best use and minimisation of potential unwanted fire signals.”

Advanced intelligence delivers highest level of protection

Tony further explains: “The Siemens unique Sinteso™ fire detection system features advanced intelligence which delivers the highest level of protection against all types of fire hazards. Each detector is configured with a unique set of parameters for each location, enabling the system to differentiate between false fire phenomena, such as steam or cooking fumes, and a real indicator of fire.”

“Its built-in intelligence means it can offer fast identification and early warning of fire, as well as eliminate potential unwanted alarms due to environmental influences such as toasters, poor housekeeping, humidity and temperature change. The Sinteso system is constantly alert, evaluating each situation minute by minute and taking decisions on complex criteria to ensure a safe environment.”

Advanced Signal Analysis integrated in detector

“Advanced Signal Analysis (ASA technology™) is integrated in the detector itself, making each device highly intelligent and 100% reliable. Innovative detection algorithms simultaneously convert signals such as smoke density and temperature into mathematical gradients and constantly evaluate according to present values. Carbon monoxide detection is combined with this unique technology providing optical, thermal and electrochemical CO sensors, which offer extremely fast detection as they continually monitor all three fire criteria – smoke, heat and carbon monoxide.”

Tony concludes: "Efficient fire detection systems save lives, protect organisations and reputations. In addition, they save the building and in the case of a hospital this could run into billions of pounds and reduce the risk of having to make a large insurance claim. There is also a danger that repeated false alarms could contribute to the downgrade of the fire service response. Furthermore, excessive unwanted fire signals can lead to complacency, putting lives at risk if and when there is a real fire. Today’s technology resolves this issue and it is false economy to install low cost systems that put organisations at risk.”

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.

Shortage Of Volunteers In Fire Service, Growing Need For Trained Personnel
Shortage Of Volunteers In Fire Service, Growing Need For Trained Personnel

Recruiting and training enough firefighters to meet community needs has been a continuing challenge for decades, especially in the case of volunteer firefighters, who make up 70% of the fire service in the United States. In some areas of the country, the problem has reached a critical stage. A recent report by a commission of lawmakers, city officials and emergency service personnel in Pennsylvania, for example, notes that the population of volunteer firefighters in the state has dwindled from 300,000 in the 1990s to fewer than 38,000. In Pennsylvania, around 90 percent of the state’s 2,400 fire companies are volunteer. Challenges Faced By Volunteers There are multiple challenges to supplying adequate personnel to the fire service. One is an aging population. About a third of small-town volunteer firefighters are over 50, and it’s not uncommon for rural firefighters to be in their 60s or 70s. Furthermore, economic challenges today require many households to have two incomes, and increased job and family responsibilities leave little time for volunteering. Commuting patterns make it less likely volunteers work in the local community, which makes them less available in case of a fire emergency. Nationwide calls to volunteer fire departments have tripled in the last three decades Also exacerbating the problem is that fire departments are facing more emergency calls than ever, including a variety of different kinds of calls. The National Volunteer Fire Council (NVFC) notes that volunteer firefighters are summoned to a wide array of emergencies across the country every day including fires, emergency medical incidents, terrorist events, natural disasters, hazardous materials incidents, water rescue emergencies, high-angle and confined space emergencies, and other general public service calls. The shortage of volunteer firefighters is being felt everywhere. Meanwhile, nationwide calls to volunteer fire departments have tripled in the last three decades. The problem is especially serious in small towns and rural areas, which are more likely to depend on volunteer firefighters. About a third of small-town volunteer firefighters are over 50, and it’s not uncommon for rural firefighters to be in their 60s or 70s Some Facts Of Interest From The NVFC Most volunteer firefighters (95%) are in departments that protect fewer than 25,000 people Of the estimated 29,727 fire departments in the U.S., 19,762 are all volunteer, and another 5,421 are mostly volunteer Nearly two-thirds (65%) of volunteer firefighters have more than five years of service Training costs are high, too. The NVFC estimates the cost to train and equip a firefighter at around $27,095. Volunteering can be costly for the volunteers, also, who drive personal cars to and from the station, for example. Even as the fire service embraces new technologies and approaches, the role of firefighters will remain essential Various measures are being undertaken to address the shortage of volunteer firefighters, including an increase in recruiting and marketing efforts to make volunteering more attractive. Given the aging firefighter population, it’s important to make entering the fire service a more desirable option for Millennials. Promotional efforts in Pennsylvania include marketing campaigns, recruitment centers, billboards, commercials in movie theaters and mailers. Need For Trained Personnel Incentives to join the fire service might include high school or college credit to volunteers or even free tuition to community colleges and state universities. Some states provide financial incentives such as property tax breaks or local income tax credits to fire volunteers. Departments are also changing to accommodate the lack of sufficient personnel. Some departments are centralising or consolidating. Others are transitioning to more full-time or paid-on-call firefighters. Even as the fire service embraces new technologies and approaches, the role of firefighters will remain essential. The role may evolve, but the need for trained personnel is a constant. Fulfilling that need will be an ongoing challenge for departments and local jurisdictions.

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.
