Bosch’s video-based fire detection solution AVIOTEC IP starlight 8000 can now also be used in tunnels to ensure reliable and early detection of smoke and flames. Therefore, it is a quick and cost-effective addition to the linear heat detectors commonly used, which react only to noticeable increases in temperature and are unable to detect smoke either.

In addition, the viewing of incidents also enables immediate verification of alarms and is a valuable aid for the emergency services. The new version of AVIOTEC is based on smoke and flames detection algorithms specially developed for use in tunnels, which have been optimized in comprehensive tests in real environments.

Intelligent Video Analysis

Bosch has also more than doubled the detection range from 50 to over 100 meters by using new lenses

The cameras require only seven lux ambient light to reliably detect smoke and flames using the integrated intelligent video analysis. For use in tunnels, Bosch has also more than doubled the detection range from 50 to over 100 meters by using new lenses. This corresponds to the usual distance between cameras for video surveillance in such environments.

Thus, AVIOTEC allows the same cameras to be used for video surveillance as well as fire detection and thereby reduces investments and operating expenses. In such scenarios, video surveillance also benefits from the intelligent video analysis in the cameras. By continuously tracking movement curves, they can automatically detect stationary vehicles as well as drivers driving the wrong way or people on the road.

Video-Based Fire Detection

As with the detection of smoke or flames, a message is also generated in these cases so that the safety personnel can immediately take appropriate measures and minimize the risk of an accident. Intelligent video analysis is implemented in the cameras themselves and therefore does not require a central server, which could represent a so-called ‘single point of failure’.

AVIOTEC was the first solution for video-based fire detection to pass the demanding test procedure of German VdS

AVIOTEC also records machine-searchable metadata of all scenes, thus enabling very rapid forensics when investigating the cause of a fire or an accident. Even before this update, AVIOTEC was the first solution for video-based fire detection to pass the demanding test procedure of German VdS Schadenverhütung GmbH. VdS had conducted the test procedure in accordance with the VdS guidelines 2203 ‘Requirements for fire protection software’ and the ‘Specifications for testing flame detectors’.

Improving Early Fire And Flame Detection

In April 2019, AVIOTEC IP starlight also received certification according to the Australian standard CSIRO TS010 for video-based fire detection systems. Apart from tunnels, as a VdS and CSIRO certified solution, AVIOTEC is suitable to improve early fire and flame detection in almost every building with large dimensions as it avoids the need of smoke or heat to migrate to the sensor.

AVIOTEC can thus be used in large warehouses, hangars, extensive shopping centers, generator halls and similar structures. Operators who are already using an AVIOTEC solution can upgrade to the new version with a free firmware update. In existing applications where a longer range is required, an upgrade can also include a purchasing of the new lens.

Outsourcing Fire And Rescue Services: How To Manage Risk And Resilience

The effective provision and management of on-site fire safety, prevention, response and protection is a core responsibility of operators of hazardous high-risk critical infrastructure and industrial manufacturing facilities around the world. Such services are typically found at airports, refineries and petrochemical plants, power stations and nuclear facilities, mines, manufacturing sites and port facilities. Driven by legislative requirements and international fire safety standards, many organizations are required to maintain and operate an on-site Rescue and Fire Fighting Service (RFFS) or for airports, an Aircraft Rescue and Fire Fighting (ARFF) Service in order to meet their compliance requirements. Legislative Compliance Failure to fully comply can expose these organizations to the risk of serious financial liability in the event of an incident, Failure to fully comply can expose these organizations to the risk of serious financial liabilityas insurers demand that risk is minimised and mitigated before they will provide cover for the site and its operations. Notwithstanding the availability of local or municipal resources to respond in the event of an emergency or serious incident, the RFFS and ARFF provision available to commercial organizations generally falls into two main options; an employed service or an outsourced service. The Decision To outsource While many organizations choose to invest in their own Fire and Rescue Service, which includes the provision of a Fire Station(s), personnel, vehicles and equipment, others have turned to outsourced service providers to enable them to meet their operational and compliance needs. So what are the factors that influence a decision to outsource and how do organizations choose between the two options? Managing risk and improving resilience The requirement and resources for an on-site fire and rescue service will be determined chiefly by the type of activity that the organization is involved in at each site or facility, the assessment of the risks associated with the processes or activities that occur on-site and the impact that any emergency incident may have on the business, its employees and on the surrounding communities. Ultimately, the motivation for investment in an on-site fire and rescue resource is rooted in the avoidance of loss, which can be both organizational, reputational and/or personal in nature and in a need to ensure the on-going stability, security and resilience of the facility and processes in question. But rather like when an insurance policy is purchased, one sincerely hopes that the Fire and Rescue Service will never need to be called upon to be utilized in a real-life emergency. A decision to outsource may be driven by purely financial motives as organizations seek to reduce costs and enhance shareholder value or by strategic and tactical factors as the business seeks to re-engineer or re-focus itself. Outsourcing enables companies to focus on their core business processes while delegating essential but non-core processes to external specialist providers Recruiting, training, resourcing, and supporting an employed on-site fire and rescue service is an expensive indirect operational cost for the business, consuming cash resources that could possibly be better invested elsewhere. The day to day management of an employed Fire, Rescue and Safety service can also sap the organization of time and energy that, while imperative to the safe, legal and ultimately the profitable operation of the facility, is not actually a core function of the business itself. Outsourcing enables companies to focus on their core business processes while delegating essential but non-core processes to external specialist providers. This releases internal resources that can be put to more effective use for other purposes, leading to greater efficiency and competitiveness. Outsourcing enables companies to focus on their core business processes while delegating essential but non-core processes to external specialist providers The question to be asked is, could an outsourced service provider deliver the required functions, tasks and compliance, maintain and improve site safety, respond effectively to any emergency incidents and add value to the organization at a more cost-effective rate than directly employing the on-site team? When properly executed, outsourcing the on-site Fire and Rescue Service can have a defining impact on the company’s revenue recognition and can deliver significant savings through lower operational and labour costs. Specialist knowledge, skills and expertise Organizations cannot realistically be experts in every business function, process and discipline, it is simply far too expensive. By utilizing outsourced service providers, companies can leverage a global knowledge base and resource centre, accessing world class capabilities, skills and expertise that they may have been precluded from previously. Managed FRS service providers often have access to a wider, more highly skilled and diverse talent pool than the client themselves and will already have in place the requisite interview and selection processes designed to select only the strongest, most appropriately qualified and experienced staff. Shared experiences coupled with specialist skills, learning and best working practices also enable the outsourced service provider to add value and resilience to and further reduce risk within the client’s operation. Shared responsibilities and liabilities Although all organizations must maintain a duty of care to operate in a safe and environmentally responsible manner, delegating fire and rescue service responsibilities to external providers can release companies of the day to day functions that are difficult to manage and control, while still realizing their benefits and upholding compliance. Outsourced FRS service providers generally are much better at deciding how to avoid risk in their areas of expertise As specialists in their field, outsourced FRS service providers generally are much better at deciding how to avoid risk in their areas of expertise than perhaps a fully employed on-site team might be. This is because the incentive to deliver a high level of service and to maintain their professional reputation while remaining profitable is potentially stronger for the outsourced provider. A further consideration if, unfortunately something does go wrong, may be that the responsibility and possible consequential contractual liability might well rest in whole or in part with the service provider, rather than the contracting client themselves. what are the potential negatives? Violations of confidentiality and intellectual property are of increasing concern to companies. This is particularly true for clients that outsource to providers from countries that may not have the same type or standards of confidentiality laws that prevail in their home jurisdiction. One way to mitigate this issue is to have strong confidentiality clauses contained within all commercial contractual documentation and employee contracts, and to make security of data and information a key performance indicator within any outsource contract. Outsourcing may in some cases result in job eliminations or employees leaving for other personal reasons, which in turn can have a negative effect on morale, loyalty and productivity among the personnel who remain. Human Resources In FRS In most cases for Fire and Rescue Service outsourcing, human resource levels are already stipulated based on the site or facility risk profile and therefore it is more likely that existing employees will simply be transferred to a new contract of employment with the new service provider, albeit perhaps on slightly different terms. There are also often hidden costs that, if not managed correctly, can quickly negate many of the anticipated savings Although most companies see an immediate benefit to the bottom line when outsourcing, there are also often hidden costs that, if not managed correctly, can quickly negate many of the anticipated savings. It should not be underestimated that, as in any period of change, increased ancillary costs such as travel and related expenses can accrue as employees travel back and forth for training and other meetings, particularly during the mobilization phase of the new contract. Making your mind up The decision to outsource the Fire and Rescue Service for a high-risk site or facility should never be made lightly. A thorough and detailed examination of the associated costs and benefits must be investigated before a go/no go decision is reached. However, if a decision to outsource is positive, then careful selection of your partner organization, taking account of both the hard and soft delivery factors for each facility, is of critical importance.

Grenfell Tower Inquiry Phase 1 Report Critical Of London Fire Brigade

The Phase 1 report of the Grenfell Tower Inquiry, released Oct. 30, examines events of 14 June, 2017, when 71 people were killed in a high-rise building fire at Grenfell Tower, a residential tower block in North Kensington, London. The report finds London Fire Brigade’s planning and preparation for such a fire was “gravely inadequate.” The report reflects the first phase of the inquiry. Investigators will consider problems related to design, maintenance and renovation of Grenfell Tower in the second phase, as well as whether building and fire regulations were adequate and adhered to. Report Suggests Lack Of Training The report found that otherwise experienced incident commanders and senior officers attending the fire had received no training in the particular dangers associated with the building’s combustible cladding, even though some senior officers were aware of similar fires that had occurred in other countries. Otherwise experienced incident commanders and senior officers attending the fire had received no training in the particular dangers Although the London Fire Brigade purports to maintain an operational risk database (ORD) for buildings in London and has a risk assessment policy accessible by all operational firefighters at an incident, the database entry for Grenfell Tower contained almost no information of any use to an incident commander called to a fire. The database information was many years out of date and did not reflect the changes made by a building refurbishment. “None of the firefighters or incident commanders on the ground seem to have been able to conceive of the possibility of a general failure of compartmentation or of a need for mass evacuation; they neither truly seized control of the situation nor were able to change strategy,” according to the report. Evacuation Plans The report continues: “National guidance requires fire and rescue services to draw up contingency evacuation plans for dealing with fires in high-rise buildings that spread beyond the compartment of origin causing a ‘stay put’ strategy to become untenable. They should understand, for any given high-rise building in their area, when a partial or full evacuation might become necessary and provide appropriate training to incident commanders.” Friends and families still await justice for their loved ones following the report The public inquiry by Rt Hon Sir Martin Moore-Bick is being conducted in parallel to investigations by the Metropolitan Police Service (MPS) and Her Majesty’s Coroner for Inner London (West), Professor Fiona The decision to evacuate the building was delayed by almost an hourWilcox. Once the Grenfell fire was out of control, the decision to evacuate the building was delayed by almost an hour, which resulted in additional fatalities. A decision should have been made to evacuate the tower between 1:30 and 1:50 a.m., according to the report. The “stay put” strategy was not questioned, even in response to early indications the building has suffered a “total failure of compartmentation.” The "Stay Put" Recommendation The ‘stay put’ recommendation was based on general wisdom that most fires are likely to be contained in small areas of a building and that anyone trying to escape is likely to run into dangerous flames, smoke-filled corridors, or to interfere with fire-fighting efforts. Obviously, it was bad advice in this case since the fast-moving fire rapidly spread and engulfed the entire building. Combustible panels on the exterior of the building accelerated the fire. The aluminium composite material (ACM) rainscreen panels with polyethylene cores acted as a source of fuel. The ACM rainscreen panels with polyethylene cores acted as a source of fuel There were serious deficiencies in command and control. Although additional resources arrived swiftly, some senior officers failed to give sufficient practical support or inform themselves quickly enough of conditions and operations within the building, according to the report. Communication Strategies Channels of communication between the control room and the incident ground were improvised, uncertain and prone to error. Control room operators did not therefore know enough about conditions in the tower or the progress of responses to individual fire survival guidance calls, so they lacked a sound basis for telling callers whether help was on its way. In a statement in response to the Phase 1 report, the London Fire Commissioner Dany Cotton said: “We are disappointed at some of the criticism of individual staff members who were placed in completely unprecedented circumstances and faced the most unimaginable conditions while trying to save the lives of others.” Furthermore, Matt Wrack, head of the Fire Brigades Union commented: “Nobody [has] explained how you would alert residents when there’s no common fire alarm system.” He also said the building was already a “death trap” when firefighters arrived.

PPE Designers To Develop Innovative Solutions For Firefighters With Maximum Protection And Comfort

Across the world, fire and rescue services vary greatly, and each will have their own unique circumstances and challenges to deal with. Firefighters in the USA and Australia are more likely to face wildland fires, whilst in the Middle East, firefighters deal more regularly with transport related fires involving hazardous materials. In many European countries, less than 10% of call-outs are fire related at all, with firefighters much more likely to attend traffic accidents, medical emergencies or flooding. A range of different climates also provide firefighters with specific challenges. Providing Optimum Protection These fabrics can offer resistance to fire, increased breathability, control of moisture, and a lighter weight Firefighters in hot and tropical Indonesia for example, will have different requirements to those in hot and arid South Africa, whilst those in Scandinavia operate in more temperate and cooler conditions. It’s important, therefore, that PPE manufacturers can provide a wide variety of options to suit particular environments and operations. PPE must be highly effective, comfortable, and suitable for the job in hand, wherever in the world the firefighters are operating. Selecting the right fabric for your PPE is the first step in providing optimum protection for the environment you are operating in. International fibre and fabric manufacturers have developed a number of highly specialized materials offering a range of benefits. Used in combination, these fabrics can offer resistance to fire, increased breathability, control of moisture, and a lighter weight. Best Quality Firefighting Garments Highly specialized and lightweight fibers for the outer-shell of a garment, for example, can provide outstanding air permeability and breathability, allowing metabolic heat to escape, whilst of course providing vital protection against the intense external heat and flames of a fire. The best quality firefighting garments combine this type of outer shell with an inner moisture barrier and liner system which draws moisture away from the skin, helping to keep the body cool and dry. Strenuous work in a hot environment causes profuse sweating, and if this sweat is not able to evaporate, the body is not able to cool itself effectively. Once the most appropriate fabric is chosen, the design and style of a garment also plays a crucial role in contributing to a firefighters’ safety. Maintaining A Comfortable Body Temperature Search and Rescue operations often take place once the immediate danger of flame is removed Whether operating in bushland, floods, on the roadside or even in extremely cold conditions, firefighters need to maintain a comfortable body temperature and stay dry. They are also likely to need to crawl, run, and climb to carry out the job in hand. Any protective clothing must be ergonomic and has to be able to work with them rather than hinder them. As a result, over and above the full structural firefighting garments available to FRSs, manufacturers have also developed innovative designs for more specific applications. For example, Search and Rescue operations often take place once the immediate danger of flame is removed, with USAR or technical rescue teams entering enclosed and confined spaces where high temperatures and often toxic smoke are hazards. Particular Protection Against Radiant Heat USAR firefighting garments therefore should be tear and puncture resistant, provide protection against blood-borne pathogens, offer physical protection at high risk points such as the knees and elbows, provide a high level of flexibility to afford maneuvrability in confined spaces, and crucially be lightweight and breathable to minimize heat stress. Alternatively, for firefighters engaged specifically in combatting forest and wildland fires, garments need to provide particular protection against radiant heat, and ideally feature a double layer of fabric to protect against sharp thorns and undergrowth. Today, many FRSs across the world use a combination of structural and technical rescue garments which can be particularly useful when faced with a range of operations requiring different levels of protection. Rescue jackets are worn with standard structural trousers when responding to a road traffic accident International Standards Of Performance For PPE Frequently, rescue jackets are worn with standard structural trousers when responding to a road traffic accident, for example. So long as these garments are tested and approved as compatible before they are used in combination, this can serve to improve ergonomics and comfort, and crucially can contribute to the lowering of heat stress in firefighters. There are currently three major standard-setting bodies on the world stage To ensure the best level of protection, most countries demand conformity with both national and international standards of performance for PPE. There are currently three major standard-setting bodies on the world stage, the National Fire Protection Association (NFPA) which covers the USA, Latin America and the Asia/Pacific region, the European Committee for Standardisation (CEN) which covers Europe, and the International Standards Organisation (ISO) which sets standards worldwide. Lighting And Communications Equipment In addition, each country will have its own National Standards Body (NSB), setting standards for its own specific interests. Ultimately, it is down to the customer to decide which standards they would like their PPE to follow. The best manufacturers can create PPE to meet a number of these standards simultaneously. These include alternative types of trouser front, leg openings and knee-pads, as well as cuff styles on fire coats Different countries, and even individual FRSs, often have particular additional requirements for their PPE, which can simply be down to style or color preference, or to accommodate particular tools or equipment they use. These include alternative types of trouser front, leg openings and knee-pads, as well as cuff styles on fire coats. Operational safety features such as integrated safety harnesses and drag rescue devices can also be specified. In addition, firefighter accessories including tools, lighting and communications equipment all have to be carried safely requiring a selection of loops, straps, D-rings, glove hooks, and pockets and flaps. Developing Innovative Solutions Finally, most FRSs aim to present a professional and clearly recognizable identity to their communities, so particular colors and badging can be an important feature of PPE. This has led to the introduction of a wide range of fabric colors and the increased use of Velcro fixings for identification badges with logos, names and roles being individually catered for. Called upon to handle an ever-increasing variety of challenges, in contrasting climates and situations, firefighters across the world are certainly faced with complex environments in which to operate. By carefully studying these conditions and listening closely to customers, PPE designers and fabric manufacturers will continue to work together to develop innovative solutions to meet these specific needs and create optimum garments for maximum protection and comfort.
