The “Routiness” of Success, Or Not..

It’s no longer just brute force and sheer physical determination that define structural fire suppression operations. Aggressive firefighting must be redefined and aligned to the built environment and associated with goal oriented tactical operations that are defined by risk assessed and analyzed tasks that are executed under battle plans that promote the best in safety practices and survivability within known hostile structural fire environments, while maintaining the values and traditions that defines the fire service.”- Christopher Naum

The lack of appreciation and the understanding of correlating principles involving fire behavior, fuel and rate of heat release and the growth stages of compartment fires within a structural occupancy are the defining paths from which the fire service must reexamine coordinated suppression operations in order to identify with; the predictability of occupancy performance during fire suppression operations, thus increasing suppression effectiveness and firefighter safety.

Our buildings have changed; the structural systems of support, the degree of Compartmentation, the characteristics of materials and the magnitude of fire loading. The structural anatomy, predictability of building performance under fire conditions, structural integrity and the extreme fire behavior; accelerated growth rate and intensively levels typically encountered in buildings of modern construction during initial and sustained fire suppression have given new meaning to the term combat fire engagement.

 

 It begs to suggest that many of today’s incident commanders, company officers and firefighters lack the clarity of understanding and comprehension that correlate to the inherent characteristics of today’s buildings, construction and occupancies and the need for refined suppression operations within the modern building construction setting.

 

We assume that the routiness or successes of our operations and incident responses equates with predictability and diminished risk to our firefighting personnel. Does your company, your officers, your commanders, your department treat all things as equals when addressing the variables of structural combat fire operations? Is the equation of Occupancy Risk balanced with Occupancy Type? Are inherent structural stability and compromise conditions adequately identified and considered in the evolving progression of an incident action plan? Or do SOP and SOG’s drive the manner in which fire ground strategies and tactics are orchestrated and implemented at the company task level?

 

How does this fit into your “culture, values and philosophy as a firefighter, officer or commander?”

Building Behaving Badly

Buildings Behaving Badly; Ok, it’s been a very quiet morning. Nothing much in the way of any work or excitment. The bells come in….Your company gets a dispatch for a report of walls showing signs of cracking and movement in the building. You arrive at curb side with the balance of the one and one assignment to find that you have a thirteen story apartment building lying in its  side on the ground. Now; how are you going to transmit that “on-scene size-up and status report?”…..The following are a series of exceptional photos from of all places China that depict a thirteen story apartment building that clearly behaved badly. The unoccupied apartment building toppled over due a series of design flaws and environmental factors. “Engine 21 to dispatch….can you fill the box and strike a fifth alarm…reporting a thirteen story apartment building laying on the ground……”  “Oh, and by the way; you may want to notify the Fire Chief on this one….”

There are some of the known facts;

  • An underground garage was being dug on the south side, to a depth of 15 feet (4.6 meters)
  • The excavated dirt was being piled up on the north side, to a height of 33 feet (10 meters)
  • The building experienced uneven lateral pressure from south and north
  • This resulted in a lateral pressure of 3,000 tonnes; which was greater than what the pilings could tolerate.
  • The building was evacuated as conditions were becoming obvious that there was a problem
  • The Building was constructed on grade with no basement foundation a series of pilings

    Predictability of Occupancy Performance during Suppression Operations

    No comments

    2-2-2009 3-20-14 PMOur buildings have changed; the structural systems of support, the degree of compartmentation, the characteristics of materials and the magnitude of fire loading. The structural anatomy, predictability of building performance under fire conditions, structural integrity and the extreme fire behavior; accelerated growth rate and intensively levels typically encountered in buildings of modern construction during initial and sustained fire suppression have given new meaning to the term combat fire engagement.

    The rules for combat structural fire suppression have changed, but we have yet to write the rule book from which the new games plans must be derived. We seek the elusive “Rosetta stone” that aligns and interprets the emerging and traditionalist acumen related to fire stream effectiveness, flow rates, cooling capacity, extreme fire behavior and fire dynamics, compartment fire theory, propagation and cooling capacity and tactical deployment all relate towards defining an engineering approach to firefighting tactics versus the manual, labor-driven tactics of line deployment and rudiment placement of water on a fuel source within the fire compartment (room).

    It’s no longer just brute force and sheer physical determination that defines structural fire suppression operations. It begs to suggest that many of today’s incident commanders, company officers and firefighters lack the clarity of understanding and comprehension that correlate to the inherent characteristics of today’s buildings, construction and occupancies and the need for refined engine company operations within the modern building construction setting. We assume that the routiness or successes of our operations and incident responses equates with predictability and diminished risk to our firefighting personnel.

    The work of such notable suppression theory pioneers as P. Grimwood, E. Hartin, S. Särdqvist and S. Svennson and the concepts surrounding 3D firefighting, B-SAHF and other emerging research from the NIST and UL are areas that today’s discerning and progressive fire officer and commanders must become well-informed and conversant. The quantitative scientific data and emerging concepts from continuing research and testing such as the NIST’s Wind Drive Fire Studies and UL’s The Structural Stability of Engineered Lumber in Fire Conditions are providing enlightenment on fire development, fuel controlled and ventilation controlled fire development, operational time-duration parameters and degradation and failure mechanisms related to compromise and structural collapse in occupancies.

    Our current generation of buildings, construction and occupancies are not as predictable as past conventional construction, therefore risk assessment, strategies and tactics must change to address these new rules of combat structural fire engagement.

    • Building Construction Systems
      • Heritage
        • Pre-1919
      • Legacy
        • 1920-1949
      • Conventional
        • 1950-1979
      • Engineered
        • 1980-2010
      • Hybrid
      • Chameleon

    The fundamental compartment that comprised a typical room configuration in terms of area (square footage), volume (height/Width), furnishings (fire load package) and materials of construction (structural anatomy) found within conventional, legacy or heritage construction provided predictability in terms of fire suppression, fire behavior, operational time and survivability (civilian/firefighter). The dramatic changes since the early 1980’s in the evolution of modern building construction and the institutionalization of engineered structural systems (ESS) have created compartment (room) areas in excess 500 SF, volumes that are open and spaciously interconnected to other habitable space, fire load packages that create extreme fire behavior, compromising structural stability in shorter time spans creating decreasing interior operational time and requiring increasing fire flow rates and volume to sustain requisite extinguishment demands.

    Commanders and Company Offices need to gain new insights and knowledge related to the modern building occupancy and to modify and adjust operating profiles in order to safe guard companies, personnel and team compositions. Strategies and tactics must be based on occupancy risk not occupancy type and must have the combined adequacy of sufficient staffing, fire flow and nozzle appliances orchestrated in a manner that identifies with the fire profiling, predictability of the occupancy profile and accounts for presumed fire behavior. Today’s engine company operations and fire suppression theory has to progress beyond the pragmatic approaches to fire suppression such as “Big Fire-Big Water principle.

    When we look at various buildings and occupancies, past operational experiences; those that were successful, and those that were not, give us experiences that define and determine how we access, react and expect similar structures and occupancies to perform at a given alarm in the future. Naturalistic (or recognition-primed) decision-making forms much of this basis. We predicate certain expectations that fire will travel in a defined (predictable) manner that fire will hold within a room and compartment for a predictable given duration of time; that the fire load and related fire flows required will be appropriate for an expected size and severity of fire encountered within a given building, occupancy, structural system; in addition to having an appropriately trained and skilled staff to perform the requisite evolutions.

    Executing tactical plans based upon faulted or inaccurate strategic insights and indicators has proven to be a common apparent cause in numerous case studies, after action reports and LODD reports. Our years of predictable fireground experience have ultimately embedded and clouded our ability to predict, assess, plan and implement incident action plans and ultimately deploy our companies-based upon the predictable performance expected of modern construction and especially those with engineered structural systems.

    If you don’t fully understand how a building truly performs or reacts under fire conditions and the variables that can influence its stability and degradation, movement of fire and products of combustion and the resource requirements for fire suppression in terms of staffing, apparatus and required fire flows, then you will be functioning and operating in a reactionary manner, that is no longer acceptable within many of our modern building types, occupancies and structures. This places higher risk to your personnel and lessens the likelihood for effective, efficient and safe operations. You’re just not doing your job effectively and you’re at RISK. These risks can equate into insurmountable operational challenges and could lead to adverse incident outcomes. Someone could get hurt, someone could die, it’s that simple; it’s that obvious.

    Considerations for changing fire flow rates, the sizing of hose line and the adequacies for fire flow demand and application rates, staffing needs for safe operations, considerations for defensive positioning and defensive operating postures must be considered, and it warrants repeating again; Reckless-Aggressive firefighting must be redefined in the built environment and associated with goal oriented tactical operations that are defined by risk assessed and analyzed tasks that are executed under battle plans that promote the best in safety practices and survivability within known hostile structural fire environments- with determined, effective and proactive firefighting

        • Resilience

        • Occupancy Hazard Profiles

    The traditional attitudes and beliefs of equating aggressive firefighting operations in all occupancy types coupled with the correlating, established and pragmatic operational strategies and tactics must not only be questioned, they need to be adjusted and modified; risk assessment, risk-benefit analysis, safety and survivability profiling, operational value and firefighter injury and LODD reduction must be further institutionalized to become a recognized part of modern firefighting operations.

    Aggressive firefighting must be redefined and aligned to the built environment and associated with goal oriented tactical operations that are defined by risk assessed and analyzed tasks that are executed under battle plans that promote the best in safety practices and survivability within known hostile structural fire environments.

    Our current generation of buildings, construction and occupancies are not as predictable as past conventional or legacy construction and occupancies;

    • Risk assessment, strategies and tactics must change to address these new rules of structural fire engagement.
    • You need to gain the knowledge and insights and to change and adjust your operating profile in order to safe guard your companies, personnel and team compositions.
    • Again strategic firefighting operations; Strategies and tactics must be based on occupancy risk not occupancy type.

    The following are quotes from Fire Chief Anthony Aiellos (ret) Hackensack (NJ) Fire Department, Fire Chief during the Hackensack Ford Fire, July, 1988…

    “If you don’t fully understand how a building truly performs or reacts under fire conditions and the variables that can influence its stability and degradation, movement of fire and products of combustion and the resource requirements for fire suppression in terms of staffing, apparatus and required fire flows, then you will be functioning and operating in a reactionary manner. This places higher risk to your personnel and lessens the likelihood for effective, efficient and safe operations. You’re just not doing your job effectively and you’re at RISK. These risks can equate into insurmountable operational challenges and could lead to adverse incident outcomes”.

    Putting the wet stuff on the red stuff

    No comments

    100653094_54cd7f3f5eThe essence of fire service suppression operations is predicated upon the deployment and application of water as an extinguishing agent, in sufficient quantities, location and duration to extinguish a fire within an enclosed structural compartment. The universal engine company correlation of: “putting the wet stuff on the red stuff” is fundamental to structural fire suppression operations but is ambiguous at best in the context of today’s modern building construction, occupancies, structural systems and building features. 

    We used to discern with a measured degree of predictability, how buildings would perform, react and fail under most fire conditions. Implementing fundamentals of firefighting and engine company operations built upon eight decades of time tested and experience proven strategies and tactics continues to be the model of suppression operations. These same fundamental strategies continue to drive methodologies and curriculums in our current training programs and academies of instructions.

    The lack of appreciation and the understanding of correlating principles involving fire behavior, fuel and rate of heat release and the growth stages of compartment fires within a structural occupancy are the defining paths from which the fire service must reexamine engine company operations in order to identify with the predictability of occupancy performance during fire suppression operations thus increasing suppression effectiveness and firefighter safety.

    Our buildings have changed; the structural systems of support, the degree of compartmentation, the characteristics of materials and the magnitude of fire loading. The structural anatomy, predictability of building performance under fire conditions, structural integrity and the extreme fire behavior; accelerated growth rate and intensively levels typically encountered in buildings of modern construction during initial and sustained fire suppression have given new meaning to the term combat fire engagement.

    Urban Search and Rescue Insights

    2 comments

    1-14-2010 9-46-14 PMUrban search-and-rescue (US&R) involves the location, rescue (extrication), and initial medical stabilization of victims trapped in confined spaces. Structural collapse is most often the cause of victims being trapped, but victims may also be trapped in transportation accidents, mines and collapsed trenches. Urban search-and-rescue is considered a “multi-hazard” discipline, as it may be needed for a variety of emergencies or disasters, including earthquakes, hurricanes, typhoons, storms and tornadoes, floods, dam failures, technological accidents, terrorist activities, and hazardous materials releases. The events may be slow in developing, as in the case of hurricanes, or sudden, as in the case of earthquakes.

    In the event of a National disater of event, FEMA deploys the three closest task forces within six hours of notification, and additional teams as necessary. The role of these task forces is to support state and local emergency responders’ efforts to locate victims and manage recovery operations. Each task force consists of two 31-person teams, four canines, and a comprehensive equipment cache. US&R task force members work in four areas of specialization: search, to find victims trapped after a disaster; rescue, which includes safely digging victims out of tons of collapsed concrete and metal; technical, made up of structural specialists who make rescues safe for the rescuers; and medical, which cares for the victims before and after a rescue.

    In addition to search-and-rescue support, FEMA provides hands-on training in search-and-rescue techniques and equipment, technical assistance to local communities, and in some cases federal grants to help communities better prepare for urban search-and-rescue operations. The bottom line in urban search-and-rescue – someday lives may be saved because of the skills these rescuers gain. These first responders consistently go to the front lines when America needs them most. We should be proud to have them as a part of our community. Not only are these first responders a national resource that can be deployed to a major disaster or structural collapse anywhere in the country. They are also the local firefighters and paramedics who answer when you call 911 at home in your local community.

    National Response Plan: Under the National Response Plan, US&R teams will provide urban search and rescue and life-saving assistance following major domestic incidents.

    US&R History

    In the early 1980s, the Fairfax County Fire & Rescue and Metro-Dade County Fire Department created elite search-and-rescue (US&R) teams trained for rescue operations in collapsed buildings. Working with the United States State Department and Office of Foreign Disaster Aid, these teams provided vital search-and-rescue support for catastrophic earthquakes in Mexico City, the Philippines and Armenia. The Federal Emergency Management Agency (FEMA) established the National Urban Search and Rescue (US&R) Response System in 1989 as a framework for structuring local emergency services personnel into integrated disaster response task forces. In 1991, the Federal Emergency Management Agency (FEMA) incorporated this concept into the Federal Response Plan (now the National Response Plan), sponsoring 25 national urban search-and-rescue task forces. Events such as the 1995 bombing of the Alfred P. Murrah building in Oklahoma City, the Northridge earthquake, the Kansas grain elevator explosion in 1998 and earthquakes in Turkey and Greece in 1999 underscore the need for highly skilled teams to rescue trapped victims.

    The terrorist attacks on the World Trade Center and the Pentagon on September 11, 2001 thrust FEMA’s Urban Search and Rescue (US&R) teams into the spotlight. Their important work transfixed a world and brought a surge of gratitude and support. Today there are 28 national task forces staffed and equipped to conduct round-the-clock search-and-rescue operations following earthquakes, tornadoes, floods, hurricanes, aircraft accidents, hazardous materials spills and catastrophic structure collapses. These task forces, complete with necessary tools and equipment, and required skills and techniques, can be deployed by FEMA for the rescue of victims of structural collapse.

      RESCUE OPERATIONS STRATEGY AND TACTICS

    Search and rescue operations in the urban disaster environment require the close interaction of all task force elements (search, rescue, medical and technical personnel) for safe and successful victim extrications. Once one or more entrapped live victims have been located, rescue extrication, coupled with appropriate medical treatment and victim removal operations, must be conducted in an organized and safe manner. This outlines current tactical considerations and general strategies that constitute a foundation for productive rescue operations.  Task force supervisory personnel must tailor the strategy and tactics to fit the general situation and specific problems encountered.

    It is incumbent on the Task Force Leader (TFL) and task force supervisory personnel to implement coordinated search tactics and strategy, collect and collate related information, and develop an effective overall rescue plan of action.

     

    Standardized rescue strategy and tactics will promote the following:

    • Effective management and coordination of rescue operations.
    • Better task force resource utilization and coordination.
    • Proper integration of all task force disciplines (i.e., medical, hazardous materials, and structures specialists, etc.) in the rescue operations.
    • The incorporation of assistance from entities outside the task force.
    • Simultaneous, multiple-site rescue operations.
    • Standardize training and increase efficiency within the task force prior to deployment and during mission operation.
    • Increase safety for all task force members involved in rescue operations.
    • Provide around-the-clock (24-hour) operations.
    • Organized and rapid victim extrication.

    The Office of U.S. Foreign Disaster Assistance (OFDA) is the office within USAID responsible for facilitating and coordinating U.S. Government emergency assistance overseas. As part of USAID’s Bureau for Democracy, Conflict, and Humanitarian Assistance (DCHA), OFDA provides humanitarian assistance to save lives, alleviate human suffering, and reduce the social and economic impact of humanitarian emergencies worldwide. USAID Fact Sheet on the Haiti Earthquake, HERE

    As reported on January 13th, the USAID reported the following:

    USAID/OFDA has deployed a Disaster Assistance Response Team (USAID/DART) to Haiti—comprising up to 17 members—and activated a Washington D.C.-based Response Management Team to support the USAID/DART. The USAID/DART will assess humanitarian needs and coordinate assistance with the U.S. Embassy in Port-au- Prince, the international community, and the Government of Haiti (GoH). Urban Search and Rescue (USAR) team, and four support staff had arrived in Port-au-Prince. As of 1615 hours local time on January 13, seven members of the USAID/DART, the 72-member Fairfax County composed of approximately 72 personnel, 6 search and rescue canines, and up to 48 tons of rescue equipment, are also deploying to Haiti. USAID/OFDA expects to support up to two additional heavy USAR teams from Florida. USAID/OFDA has also authorized the deployment of a three-person Americas Support Team (AST) to Haiti. The AST, staffed by additional Fairfax County USAR members and funded by USAID/OFDA, will supplement the U.N. Disaster Assessment Country (UNDAC) team in Haiti. In addition, both the Fairfax County and Los Angeles County Fire Departments are seconding staff members to directly support the UNDAC team. Two USAID/OFDA-supported heavy USAR teams from Fairfax County, VA, and Los Angeles County, CA.

    STRATEGIC CONSIDERATIONS

    Excerpts taken from the USAR Response Systems Operations Manual
    street-vertical_1559212i

    Haiti Collapse Magnitude

    The most effective rescue strategy should blend all viable tactical capabilities into a logical plan of operation. The general strategic considerations are outlined as follows:

    Rescue Team Composition: A task force rescue team is comprised of four, 6-person rescue squads. Two Rescue Team Managers are assigned to provide continuous supervision for the rescue team. A squad is composed of a Rescue Squad Officer and five Rescue Specialists.

    Personnel Deployment: One of the most important strategic considerations for the task force supervisory personnel (the Rescue Team Manager in particular) is the deployment of task force personnel at the start of mission operations. When the task force arrives at the assigned location, it may be best to commit all task force personnel to the initial objectives that must be addressed. This would include Base of Operations (BoO) set-up, search and reconnaissance activities, equipment cache set-up, rescue operations, etc. Depending upon the general conditions present, it may be most appropriate to attempt the following deployment guideline:

     1-14-2010 9-23-06 PM

     

     

     

    As the task force moves into alternating 12-hour operational periods, there should be an overlap of the shifts to allow for briefings and information exchange to promote the continuity of operations. As the operations near the end of the initial 8 to 12-hour time frame, it may be necessary to scale back to handling only one or two simultaneous operations. This reduction in rescue operations is the trade off for allowing sleep rotations for each half of the task force. Deviations from the suggested guideline might be required, depending upon the conditions that are present. There is the possibility that the ongoing size-up and planning information could indicate there being a specific number of viable rescue opportunities that could be accomplished. In that case it may be most appropriate to deploy all task force personnel for a full-scale “blitz” of the planned 24 to 30-hour duration. This would necessitate the full stand down of the task force at the conclusion of this blitz.

    Task Force Equipment Cache Management: The overall effectiveness of the task force depends upon the prompt availability of the tools, equipment, and supplies in the task force cache. The organization and management of the cache is important. The equipment cache requires immediate attention once the BoO has been identified.  The cache set-up must be addressed before significant rescue operations can be supported. Rescue personnel must be effectively trained in, and adhere to, all procedures related to equipment issue, tracking, and retrieval, as outlined in the Property Accountability and Resource Tracking System. The limited number of specialized tools may require them to be shared between one or more rescue sites during simultaneous operations. It is incumbent upon the task force Logistics Specialists, in conjunction with the Rescue Team Managers and Squad Officers, to coordinate the sharing and movement of these tools between the rescue sites.

    Assistance with Search Activities: It may be necessary to assign additional task force personnel to search operations to identify, assess, and prioritize rescue opportunities.

    Rescue Site Management and Coordination: Each rescue work site must have one person in charge to maintain unity of command. The Rescue Squad Officer of each rescue squad is responsible for all activities of the assigned rescue site including safety when a single squad operates alone. At large or complex rescue operations that require the commitment of two or more rescue squads to a single operation, the Rescue Team Manager may assume command or assign one of the Rescue Squad Officers to be in charge of the site. A Safety Officer should be identified at each rescue site.

    Rescue Site Communications: Communication is fundamental to effective operation of the task force.  The task force should be provided with radio channels for command and control, logistics, and tactical operations as needed.

    Rescue Site Engagement/Disengagement: A standardized method of engaging and disengaging a rescue site should be followed.

    TACTICAL CONSIDERATIONS

    Rescue Integration in Search Activities: Task force rescue personnel may be required to assist the canine and technical search personnel with search and reconnaissance activities. This may include safety assessments at collapse sites, gaining access to voids and other difficult areas, deploying equipment, and conducting physical search operations. Individual void inspections, or combined listening operations may require shoring and stabilization prior to entry. Rescue personnel may be used to staff search and reconnaissance teams. There are specific protocols for Search Strategy and Tactics and Structure Triage, Assessment, and Marking System. These combined operations would be coordinated between the Search Team and Rescue Team Managers, the Rescue Squad Officers, or other appropriate task force personnel.

    Rescue Site Management and Coordination: Size-up and site control activities should be completed before rescue operations begin.Once the size-up is completed and the plan of action developed, a short team briefing should be conducted to include safety considerations, structural concerns, hazard identification, and emergency signaling and evacuation procedures. As rescue opportunities are identified, it is important that rescue personnel adhere to a consistent, formalized site management procedure to ensure the safe, effective operation of the rescue squads. The following considerations should be addressed:

    • Hazard assessment and mitigation. This could include removing trip hazards, boards with exposed nails, shutting off utilities, etc.
    • A collapse hazard zone (hot zone) should be established and clearly defined along with the operational work area.
    • All bystanders should be excluded from the operational work area.
    • An equipment assembly area and cutting workstation should be organized at an advantageous location.

    Rescue Site Set-Up: In order to ensure safe and effective rescue operations, the area immediately surrounding the selected work site should be secured. A collapse hazard zone is established for the purpose of controlling all access to the immediate area of the collapse that could be impacted by further building collapse, falling debris, or other dangers. The only individuals allowed within this area are authorized personnel involved in search or extrication of victims. The collapse hazard zone will be identified by an X-type cordon of flagging or rope (criss-crossed) as outlined in protocols for Structural Triage, Assessment, and Marking. When establishing the perimeter of the operational work area, the needs of the following activities must be provided for and properly identified:

    • Medical treatment area 
      • Personnel staging area
      • Rescue equipment staging area
      • Cribbing/shoring working area
      • Access/entry routes
      • Security and environmental protection.

    Inter-discipline Coordination: As the Rescue Team Managers and Squad Officers focus on the appropriate tactics and procedures related to victim extrication, they may also utilize other task force disciplines in the ongoing operations.

    Site/Personnel Safety: Safety of the task force personnel is the single most important consideration during mission operations.  As a minimum, the following considerations should be addressed for rescue operations:

    • The safety of personnel operating around collapsed/compromised structures.
    • Emergency signaling and evacuation procedures. 
    •  Hailing devices shall be used to sound the appropriate signals as follows:
    • Cease Operation/All Quiet 1 long blast (3 seconds)
    •  Evacuate the Area               3 short blasts (1 second each)
    •  Resume Operations             1 long and 1 short blast.
    • Personnel Rest and Rehabilitation (R&R).
    • Critical incident stress debriefing or defusing may be required.
    • Personnel hygiene. Considerations would be the exposure and/or contact with victim body fluids, inhalation or ingestion of dusts and contaminated atmospheres, water, etc., and minor injuries.1-14-2010 9-23-56 PM

    Building Types

    No comments

    newyork-ogleThe United States Fire Administration (USFA) recently published a series of bulletins under their highly acclaimed Coffee Break Training series of informational bulletins. This series provided insights and awareness of how Buildings are “types” from a codes perspective related to fire resistance. All firefighters and officers need to have a firm understanding of the principles, concepts and methodologies of building construction. Another mission critical concept that I’ve discussed recently is operational risks and tactical deployment must be based upon Occupancy Risk, not Occupancy Type.

    Remember; Building Knowledge = Firefighter Safety.

    It’s more than just Size-Up; Situational Awareness and Dynamic Risk Assessment

    1 comment
    FLASHO1Dynamic Risk Assessment is commonly used to describe a process of risk assessment being carried out in a changing or evolving environment, where what is being assessed is developing as the process itself is being undertaken.
    This is further problematical for the Incident Commander when confronted with competing or conflicting incident priorities, demands or distractions before a complete appreciation of all mission critical or essential information and data has been obtained. The dynamic management of risk is all about effective, informed and decisive decision making during all phases of an incident.
    Situation Awareness, [SA], is the perception of environmental elements within a volume of time and space, the comprehension of their meaning, and the projection of their status in the near future. It is also a field of study concerned with perception of the environment critical to decision-makers in complex, dynamic situations and incidents.
    Both the 2006 and 2007 Firefighter Near-Miss Reporting System Annual Reports identified a lack of situational awareness as the highest contributing factor to near misses reported. Situation Awareness (SA) involves being aware of what is happening around you at an incident to understand how information, events, and your own actions will impact operational goals and incident objectives, both now and in the near future. Lacking SA or having inadequate SA has been identified as one of the primary factors in accidents attributed to human error (Hartel, Smith, & Prince, 1991) (Nullmeyer, Stella, Montijo, & Harden, 2005). Situation Awareness becomes especially important in work related domains where the information flow can be quite high and poor decisions can lead to serious consequences.
    To the Incident commander, Fire Officer or firefighter, knowing what’s going on around you, and understanding the consequences is mission critical to incident stabilization and mitigation and profoundly crucial in terms of personnel safety. The integration of Situational Awareness and Dynamic Risk Assessment is a mission critical element in strategic incident command management and company level tactical operations as we go forward into the next decade.
    Traditional incident scene size-up is antiquated and no longer appropriate or applicable to modern fire service operations.Situational awareness is a combination of attitudes, previously learned knowledge and new information gained from the incident scene and environment that enables the strategic commanders, decision-makers and tactical companies to gather the information they need to make effective decisions that will keep their firefighters and resources out of harm’s way, reducing the likelihood of adverse or detrimental effects.
    According to a 1998 published TriData study report, “Situational Awareness is one of the most difficult skills to master and is a weakness in the fire community. The report goes on to state that “The culture must change so that [personnel] are observing, thinking, and discussing the situation constantly.” It’s all about implementing effective human performance tools; perceptions versus reality, expectations versus realization, comprehension and forecasting, informed decision-making and calculated and formulated risk.
     
    It’s a whole lot more than just “Size-Up”.  What do you think?

    august_detailAs we transition into a new year, and as plans begin to take place that frame and outline the year’s activities, foremost in this planning, preparation, scheduling and outlook should be those activities and commitments that training, education and skill development can be implemented and enhanced. Take the initiative to recognize and identify training and operational gaps and distinguish the risk and options available to lessen or eliminate the risk and reduce the gap deficiencies. Take the time to implement effective, accurate and frequent training and skill development drills, training curriculums and programs.

    Don’t sacrifice or forego on this mission critical area when so much is at stake in the domain of combat structural fire suppression. Understand the predictability of performance in the buildings and occupancies not only in your jurisdiction, first or second-due areas, but also in those areas that you may be called upon to respond to for greater alarms or mutual aid. Remember Building Knowledge = Firefighter Safety.

    Keep an eye in the rear view mirror; learning from the wisdom and knowledge from where you’ve been, what you’ve done and all your past experiences and practice; but at the same time focusing on the road before you with keen attentiveness on situational awareness, anticipating error-likely conditions and balanced risk assessment and operational management in both your strategic and tactical deployments. 

    Twenty Ten(2010)

     Here are twenty (20) Suggested activities or initiatives for you to consider in 2010….

    Above all, be safe in all your endeavors, assignments and incident tasks.

    1. Regardless of my years of experience, I will increase my understanding of the basic principles of Building Construction, because; Building Knowledge=Firefighter Safety.  
    2. Identify ten (10) buildings within your first-due or response district and complete a pre-fire plan and present this to my company of organization.
    3. Identify an area where new residential construction is underway and follow the construction process from foundation through completion to gain an understanding of operational issues.
    4. I will complete the UL Structural stability of engineered lumber in fire conditions online course and implement the lessons learned in my strategic and tactical operations.
    5. I will not take any building or occupancy for granted, and shall take all precautions to ensure crew integrity and safety during my task assignments.
    6. Complete a 360 assessment of all buildings upon arrival, when ever feasible to gain reconnaissance information on the building and incident risks and implement this info into my strategic, tactical plans or company task assignments.
    7. Research the issues affecting; Engineered Structural Systems (ESS), Fire Behavior/Fire Dynamics or Fire Suppression Management/Fire Loading and develop a training drill to share the lessons learned.
    8. Select a new or previous published fire service text book and read up on a subject area that I may have neglected or ignored to increase my skill set.
    9. Implement an objective approach towards effective risk assessment and profiling of all buildings and occupancies during incident operations and implement balanced tactical deployment with aggressive/measured assignments; recognizing that my company and I are not invincible.
    10. During demanding Combat Structural Fire Engagements, I will; Do the Right Thing at the Right Time for the Right Reasons and will not practice Tactical Entertainment.
    11. Read the Report of the Week (ROTW) on the National Firefighter Near-Miss Reporting System web site and share the operating experience (OE) lessons with my company or department, to reduce the likelihood of a similar or more serious event.
    12. I will read Ten (10) NIOSH Firefighter Fatality Investigation and Prevention Program Reports and present the lessons learned in a discussion, table top, drill or training program.
    13. I will attend a regional or national training conference to increase my perspective and awareness of other firefighting, safety or operational methodologies, process or practices to increase firefighter safety in my home organization.
    14. I will increase my understanding of the NFFF Everyone Goes Home Program initiatives, including the Sixteen Firefighter Life Safety Initiatives, Safety Thru Leadership and the Courage to Be Safe Programs and other new program initiatives and advocate and promote enhanced safety measures in my organization.
    15. I will advocate and promote safe and defensive apparatus operations during emergency responses and will always buckle-up my seat belt and ensure my crew is always belted-in, not placing my company at risk and obeying traffic signals and postings.
    16. I will implement the New Rules of Engagement during combat structural fire operations; while monitoring and reacting to on-going building performance and fire behavior.
    17. I will increase my understanding of the Predictability of Building Performance and base my operational deployments on Occupancy Risk not Occupancy Type.
    18. I will become a mentor to a new or less experienced firefighter and promote the traditions, honor and duty of our fire service profession, tempered with an emphasis on firefighter safety, survival and wellness.
    19. I will take NO emergency incident responses as being routine in nature, due to frequency , regularity or  past performance, demands or outcomes, nor will I take any building for granted; Company, Team and personal safety and integrity is paramount and I will not be complacent, but remain vigilant based upon my training, skills and experience.
    20. This one’s for you to identify and fill in………..

    Ensure you’re glancing occasionally in your rear view mirror to monitor where you’ve been, while driving your initiatives, programs, processes and actions forward. Above all, maintain the courage to be safe. We don’t know what’s in the cards on any given day, but the citizens we protect can rest assured, we will do our job as firefighters, to the best of our abilities, because of who we are; today, in 2010 and certainly well into the next decade and beyond. Stay safe, with the hopes for a Happy New Year.
