Reflecting on These Days of June

2 comments

Over the next few days, much will be written up reflecting on a number of past historical events that resonate with the rich heritage, honor and tradition that makes this Fire Service what it is.  Anniversaries come and go; remembrance, sorrow, grief and respect; the good and the bad all seem to come streaming back-or these emotions and the lessons from these events seem to diminish and fade over even the shortest spans of time that may have passed.  Or may have been all but forgotten as a new generation comes through the firehouse doors. Yes it does happen.

We need to learn, remember and implement the lessons from the past, especially when we refer to or are confronted with History Repeating Events (HRE) or similar situational profiles. We must develop an inherent understanding on the Predictability of Performance of our building and occupancies and truly understand and apply effective strategic and tactical plans under combat structural fire engagement. There are legacies for operational safety; do you know what they where, who was affected and what the outcomes where?

We must implement a process of Tactical Patience that correlates to  the manner in which our building perform, the dynamics and behavior of fire that affects them and defines our firefighting methodologies when we engage in our missions of operations within the built environment. I’ll post more on Tactical Patience after I roll this emerging concept out at my lecture program presentation at the upcoming Southeastern Association of Fire Chief’s Conference (SEAFC) in Louisville later this month.

The built-environments that form and shape our response districts and communities pose unique challenges to the day-to-day responses of fire departments and their subsequent operations during combat structural fire engagement. With the variety of occupancies and building characteristics present, there are definable degrees of risk potential with recognizable strategic and tactical measures that must be taken. Although each occupancy type presents variables that dictate how a particular incident is handled, most company operations evolve from basic strategic and tactical principles rooted in past performance and operations at similar structures. This basis is based upon Predictability of Performance.

  • Modern building construction is no longer predicable
  • Command & company officer technical knowledge may be diminished or deficient
  • Technological Advancements in construction and materials have exceeded conventional fire suppression practices
  • Some fire suppression tactics are faulted or inappropriate, requiring innovative models and methods.
  • Fire Dynamics and Fire Behavior is not considered during fireground size-up and assessment
  • Risk Management is either not practiced or willfully ignored during most incident operations
  • Some departments or officers show and indifference to safety and risk management
  • Command & Company Officer dereliction
  • Nothing is going to happen to me (us)

STOP THE ENTERTAINMENT
There’s another factor contributing to unsafe practices, one that we rarely talk about. In short, we need to stop “entertaining” ourselves during fire suppression operations and instead focus on comprehending and reacting to evolving risks. Rather than practicing appropriate risk management, it is suggested that some individuals employ adverse behaviors that occur on a tactical level while Incident Commanders and Company Officers believe firefighters are completing their assigned tasks, thus compromising accountability.

These behaviors include;
• Tactical amusement: engaging in any practice or tactic during fire suppression, support tasks or operations that places personnel at risk for the sake of entertainment.

• Tactical diversion: diverting from an assignment while engaging in fire suppression, support tasks or operations in such a way that places personnel at risk.

• Tactical circumvention: deliberately “getting around” an assignment or disregarding risk assessment and incident action plans.

Here’s the expanded versions in case this is th first time you’ve seen them;

TACTICAL AMUSEMENT *tak-ti-kəl ə- *myüz-mənt
1: of or relating to structural fireground tactics: as a (1) a means of amusing or entertaining during fire suppression, support tasks or operations that places personnel at risk
2: the condition of being amused while engaging in fire suppression, support tasks or operations that places personnel at risk
3: pleasurable diversion while engaging in fire suppression, support tasks or operations: entertainment; that places personnel at risk

TACTICAL DIVERSION *tak-ti-kəl də- *vər-zhən
1: the reckless act or an instance of diverting from an assignment, task, operation or activity while engaging in fire suppression, support tasks or operation for the sake of amusing or entertainment; that places personnel at risk
2: the reckless act of self determined task operations that diverts or amuses from defined risk assessment and incident action plans; that places personnel at risk

TACTICAL CIRCUMVENTION *tak-ti-kəl sər-kəm- *ven(t)-shən
1: to deliberately manage to get around especially by ingenuity or approach that diverts for the purpose of amusing; assignment, operations or tasks that countermand or disregard defined risk assessment and incident action plans; that places personnel at risk

TACTICAL PATIENCE (NEW) This is a new one that’s called Tactical Patience…I’ll post more on Tactical Patience after I roll this out at the upcoming Southeast Association of Fire Chief’s Conference (SAFC) in Louisville later this month.

If we’re going to reduce firefighter injuries and deaths, we must be doing the right thing, at the right time, for the right reasons, and in the right place. We must stop the entertainment.

The demands and requirements of modern firefighting will continue to require the placement of personnel within situations and buildings that carry risk, uncertainty and inherent danger. Fire suppression tactics must be adjusted for the rapidly changing methods and materials impacting all forms of building construction, occupancies and structures. The need to redefine the art and science of firefighting is nearly upon us. Some things do stand the test of time, others need to adjust, evolve and change. Not for the sake of change only, but for the emerging and evolving buildings, structures and occupancies being built, developed or renovated in our communities. 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 know hostile structural fire environments, while maintaining the values and tradition that defines the fire service.

NIST Report on Residential Fireground Field Experiments ISSUED

1 comment

4-28-2010 5-18-34 PMReport-on-Residential-Fireground-Field-Experiments

The NIST Firefighter Safety and Deployment Study; Titled- Report on Residential Fireground Field Experiements was issued this morning. A copy of the report is attached. The report is also available for download at the NIST, HERE

Report Abstract:

Service expectations placed on the fire service, including Emergency Medical Services (EMS), response to natural disasters, hazardous materials incidents, and acts of terrorism, have steadily increased. However, local decision-makers are challenged to balance these community service expectations with finite resources without a solid technical foundation for evaluating the impact of staffing and deployment decisions on the safety of the public and firefighters. For the first time, this study investigates the effect of varying crew size, first apparatus arrival time, and response time on firefighter safety, overall task completion, and interior residential tenability using realistic residential fires.

This study is also unique because of the array of stakeholders and the caliber of technical experts involved. Additionally, the structure used in the field experiments included customized instrumentation; all related industry standards were followed; and robust research methods were used. The results and conclusions will directly inform the NPFA 1710 Technical Committee, who is responsible for developing consensus industry deployment standards.

This report presents the results of more than 60 laboratory and residential fireground experiments designed to quantify the effects of various fire department deployment configurations on the most common type of fire—a low hazard residential structure fire. For the fireground experiments, a 2,000 sq ft (186 m2), two-story residential structure was designed and built at the Montgomery County Public Safety Training Academy in Rockville, MD. Fire crews from Montgomery County, MD and Fairfax County.

A were deployed in response to live fires within this facility. In addition to systematically controlling for the arrival times of the first and subsequent fire apparatus, crew size was varied to consider two-, three-, four-, and five-person staffing. Each deployment performed a series of 22 tasks that were timed, while the thermal and toxic environment inside the structure was measured. Additional experiments with larger fuel loads as well as fire modeling produced additional insight. Report results quantify the effectiveness of crew size, first-due engine arrival time, and apparatus arrival stagger on the duration and time to completion of the key 22 fireground tasks and the effect on occupant and firefighter safety.

We will review the report findings and provide insights over the upcoming weekend.

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?”

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.

Engineered Structural Systems- Hazards

No comments

600x6CNN recently presented an informative piece on the continuing trends in the design and use of engineered structural systems (ESS) . CNN correspondant Gerri Willis provides an informative and  insightful look at something the fire service knows all too well.  Here’s some additional information for you; According to the Wood Truss Council of America (WTCA), wooden trusses are used in roof systems in more than 60% of all buildings in the United States [SBCMAG 2004]. Truss and related engineered wooden floor systems are also becoming more common. Today, more engineered structures use lighter weight materials, producing larger spans and clear openings. Trusses can be designed to carry expected loads, be produced economically, be safely handled, and reduce construction costs.

Engineered building components may provide adequate strength under normal loading; but under fire conditions, these truss systems can become weakened and fail, leading to the collapse of roofs, floors, and possibly the entire structure. Truss systems are usually hidden, and fires within truss systems may go unnoticed for long periods of time, resulting in loss of integrity.

Structural design codes often do not factor in this decreased system integrity, as fire degrades the structural members. Fire fighters typically rely on warning signs to indicate imminent truss failure such as roofs and floors that feel spongy or are visibly sagging. Quite often, these warning signs are not good predictors of truss system failures. The United States Fire Administration (USFA) reports that during 1990-2000, structural fires and explosions accounted for 46.1% of all reported fire fighter fatalities (500 of 1,085) [USFA 2002].  Statistics compiled by the WTCA suggest that 4.7% of the total fatalities (108 of 2,286) during 1980-2001 were due to structural collapse [Grundahl 2003b]. Fifteen separate incidents investigated by NIOSH identified at least 20 fatalities and 12 injuries that have occurred from 1998-2003 during fire-fighting operations in buildings containing truss systems.

http://us.cnn.com/video/?/video/living/2009/12/18/willis.new.housing.fire.danger.cnn CNN Reports on ESS Dangers

At least three scenarios can occur in which fire fighters suffer fatalities and injuries while operating at fires involving truss roof and floor systems:
1. While fire fighters are operating above a burning roof or floor truss , they may fall into a fire as the sheathing or the truss system collapses below them.
2. While fire fighters are operating below the roof or floor inside a building with burning truss floor or roof structures , the trusses may collapse onto them.
3. While fire fighters are operating outside a building with burning trusses , the floor or roof trusses may collapse and cause a secondary wall collapse.

A million dollar Baltimore County, Maryland  home was destroyed Sunday December 13, 2009  by a fire that tore through the 4,700-square-foot structure with such intensity that firefighters were forced to battle the flames from the exterior. Shortly after 21:00 hours, Baltimore County Fire Dispatch alerted crews for Fire Box 50-2 at 12607 Nancy Lee Court in the Worthington Trace subdivision in the Chestnut Ridge area. As firefighters were responding, dispatch advised they were receiving multiple calls to 911, with some reporting the entire house was on fire. While en route to the scene, Chestnut Ridge Volunteer Fire Company Captain Dan Uddeme reported heavy fire was visible and requested a 2nd alarm and a Tanker Strike Team as the house sits in an area without fire hydrants. Upon arrival, Capt. Uddeme reported fire had consumed the entire 2nd floor and roof area and was spreading. Firefighters were forced to use exterior operations due to the heavy volume of fire. Responding units set up for rural water operations, shuttling more than 17,000 gallons of water from an underground tank on Greenspring Avenue and Walnut Avenue near the scene. Reisterstown Volunteer Fire Companys Engine 412 was also utilized for its Compressed Air Foam System, with several handlines and the ladder pipe from Glyndon Volunteers Truck 404 flowing foam. The Baltimore County Fire Investigation Division is investigating to determine the fires cause and origin. Video and data was obtained from Michael Schwartzberg’s Firepix1075 . Additional photos, HERE and newsreports, HERE

While watching the video, take the time to listen to the wind howling across the mic and observe the intesity level of the fire severity and propogation in the Charlie side. This provides an opportunity for those that are not familiar with the NIST Wind Driven Fire Studies or the PWC (VA) Kyle Wilson LODD to take some time to read about the affects of wind on incident operations, strategies and tactical personnel safety. This was a 4,700 SF large volume residential structure. Think about the performance and your deparment’s capabilities? Remember, it’s not “just” a house fire

Take a look at the Prince William County (VA) Fire & Rescue case study information related to Technician I Kyle Wilson – LODD Report. This event: Technician Kyle Wilson died in the line of duty on April 16, 2007 while performing search and rescue operations at a house fire on Marsh Overlook Drive, located in the Woodbridge area of Prince William County. On that day, Technician Wilson was part of the firefighter staffing on Tower 512 which responded to the house fire that was dispatched at 0603 hours. The Prince William County area was under a high wind advisory as a nor’eastern storm moved through the area. Sustained winds of 25 mph with gusts up to 48 mph were prevalent in the area at the time of the fire dispatch to Marsh Overlook Drive. Initial arriving units reported heavy fire on the exterior of two sides of the single family house and crews suspected that the occupants were still inside the house sleeping because of the early morning hour. A search of the upstairs bedroom commenced for the possible victims. A rapid and catastrophic change of fire and smoke conditions occurred in the interior of the house within minutes of Tower 512’s crew entering the structure. Technician Wilson became trapped and was unable to locate an immediate exit out of the hostile environment. Mayday radio transmissions were made by crews and by Technician Kyle Wilson of the life-threatening situation. Valiant and repeated rescue attempts to locate and remove Technician Wilson were made by the firefighting crews during extreme fire, heat and smoke conditions. Firefighters were forced from the structure as the house began to collapse on them and intense fire, heat and smoke conditions developed. Technician Wilson succumbed to the fire and the cause of death was reported by the medical examiner to be thermal and inhalation injuries.

National Institute of Standards and Technology – NIST Wind Driven Fire Research HERE Smoke and heat spreading through the corridors and the stairs of a building during a fire can limit building occupants’ ability to escape and can limit fire fighters’ ability to rescue them.  Changes in the building’s ventilation or presence of an external wind can increase the energy release of the fire.  This can also increase the spread of fire gases through the building.  In some cases, such as the Cook County Administration Building fire in October 2003, the fire gas flow, into the corridors and the stairway prevented fire fighters from suppressing the fire from inside the structure.  This fire resulted in 6 building occupant fatalities and fire fighter injuries in the stairway.  The Fire Department of New York City has experienced many wind driven fire incidents which have resulted in fire fighter fatalities and injuries.

What tactics or tools are appropriate for use with a wind driven fire and how should the tactics or tools be implemented?  Positive Pressure Ventilation (PPV) is being used by fire departments on smaller structures, such as single family homes, to control the fire flow by introducing pressure from the front door and venting the house through a strategic exit opening.  If done correctly, this tactic can remove significant amounts of heat and smoke from the structure, thus improving the fire fighters’ working environment and improving the chances of survival for the building occupants.  NIST has completed several studies which have a two fold impact: 1) providing guidance on the safe use of PPV and 2) characterizing and validating the modeling of PPV with a computational fluid dynamics (CFD) computer model, so that the model can be used as a training tool for the fire service.
