NIST Advanced Fire Service Technologies Program

Summary:

This program focuses on improving the safety and effectiveness of fire fighters by enabling the effective use of existing and new technologies and tactics.  Increasing the safety and effectiveness is critical to reducing fire fighter fatalities and injuries, as well as the cost of fire service.  For existing and emerging technologies, performance must be measured in a scientifically sound method.  The fire service is learning to exploit existing technologies such as thermal imaging, positive pressure ventilation techniques, and is anticipating the integration of emerging innovative technologies, such as tactical decision aids, in-building sensors, training simulators, and the next generation of respirators.  Combining lab- and field-scale experiments with computer fire models, this program is developing science-based performance metrics which will allow industry to address the real functional needs of the fire service and will provide industry with the tools to develop and integrate innovative technology into fire fighter protective equipment and tactics.   

 

 

Description:

Objective:To provide the measurement science that is critical for developing and implementing innovative technology, enabling an information rich environment, and integrating the science into training tools which will improve the effectiveness and safety of emergency responders over the next five years, FY2011 – FY2015

What is the problem?Fire service operations, fatalities, and injuries accounted for approximately one-third of the approximately $320 B of the total social cost of fire in 2006 (Hall)[1]. There were over 1.6 million fires in 2006 leading to 83,000 injuries and 89 fatalities to fire fighters (NFIRS)[2] For existing and emerging technologies, it is critical that performance can be measured and evaluated in a scientifically sound method.  The fire service is learning to exploit existing technologies such as thermal imagers, wind driven fire techniques, and is anticipating the integration of emerging innovative technologies, such as tactical decision aids, training simulators, and heads-up displays.  Without adequate performance metrics, emergency responders may acquire technologies that do not perform or worse yet, place the users at risk of greater harm.   For example, personal alert safety system (PASS) devices are designed to provide an alarm signal of 95 dB when a fire fighter becomes incapacitated.   During high temperature exposure tests, NIST[3] discovered the alarm signal generator failed at high temperatures; basically, PASS devices were failing in conditions where fire fighters would most need a PASS device.  Performance testing which incorporated realistic fire fighting conditions would have identified this limitation.    For emerging technologies, science-based performance metrics allow industry to understand the real functional needs of the fire service and provide industry with the tools to develop and integrate innovative technology that addresses these needs, but still performs under fire conditions.    Whether a technology already exists or is just emerging, it needs to be transferred to the fire service.  Fire fighting simulators and training programs transfer technology to the fire service, allowing emergency responders to perform more effectively and safely.

The lack of adequate measurement science directly impacts the protective equipment and technology utilized by the over one million fire fighters in over 32,000 fire departments in the US.   The National Fire Research Agenda Symposium,[4] which was attended by over 50 organizations, including[5] the fire service, IAFC, IAFF, and NVFC, manufacturers, DHS, & USFA, identified and prioritized research needs for fire fighters.  “Urgent and critical issues” included improved respiratory protection, situational awareness technology, tactical decision aids, lessons learned/fire reconstructions, and strategies that would reduce injuries and fatalities.  Over 60 participants in the Innovative Fire Protection Workshop[6] held at NIST identified locator systems, tactical decision aids, improved respirators, and enhanced turnout gear as high priority research needs.    Workshops conducted by NIST in San Antonio, TX and Emmitsburg, MD, also identified tactical decision aids, protective clothing, locator systems, suppression, and ventilation as critical research needs for the fire service.[7] [8]

Why is it hard to solve   The measurement science problems are hard to solve because the typical emergency responder operating conditions are extremely difficult and the operating environment impacts different technologies in different ways.    For example, the wet, high thermal flux, and high temperature scenarios adversely affect the performance of thermal imagers, protective clothing, and respirators.   But the materials of construction, wood, concrete, or steel, and whether a structure is a single family residence, a commercial warehouse, or a high rise office creates issues for locator/tracking systems, tactical decision aids, and positive pressure ventilation.   For protective clothing the metrics must include high heat flux and moisture, but for locator technology, the metrics needs to include the signal attenuation caused by wood, steel, and concrete.  Given the harsh operating conditions in a wide range of buildings, one cannot simply develop a single performance metric or test methodology, but one is forced to develop specific performance metrics for each different technology. 

How is it solved today, and by whom   The measurement science issues have not been solved. The fire services are not able to develop their own performance metrics because they do not have the technical training or resources to develop and conduct performance tests of existing or emerging technology/ equipment for common fire scenarios.   Manufacturers have technical staff and facilities to conduct performance tests, but are unlikely to conduct or release data that places their product at a disadvantage in a highly competitive market.  NIOSH’s National Personal Protection Technology Laboratory (NPPTL) has expertise in respirator certification and does conduct human physiology testing, but it has no capability to expose protective equipment to high temperature conditions.   NFPA’s Fire Research Foundation prioritizes emergency responder research needs for its standards committee.   However, since the Foundation has limited funding and no research facilities, its role in resolving measurement science issues is more of a coordinating function;  getting those with funding together with those who can actually do the work.  For the past nine years, the AFST Program has been an active leader and participant in developing measurement science for fire service technology

Why NIST    NIST is an unbiased source of measurement methods and standards needed to assure that emergency responders can select quality, reliable new technology equipment that meets performance expectations.  NIST has unsurpassed experience in fire testing and is a trusted source of unbiased, science-based, quantifiable recommendations to standards developing organizations including NFPA, ASTM, and ISO

The AFST Program is a critical component as to how BFRL enhances economic security and improves the quality of life by reducing fire fighter and civilian fatalities and injuries and property losses due to fire.  AFST also promotes the development and implementation of new technology which promotes U.S. innovation and competitiveness by providing measurement science.   Performance based standards allow the fire safety industries to evaluate new technology and understand when the new technology is a true step forward not just opportunistic marketing.  As part of the Measurement Science for Innovative Fire Protection Strategic Goal, the AFST Program moves the science developed by other BFRL Programs out to the fire service and fire safety industries.  AFST contributes to and utilizes BFRL core competencies in fire protection and fire spread within buildings and communities.  

What is the new technical idea? The AFST Program develops performance metrics and test methods that directly relate to the operating environment and tasks performed by emergency responders.  For existing equipment or tactics, if relevant performance data is available, then a meaningful performance metric can be developed, but too often the necessary data is not readily available.  For protective clothing there is a significant amount of data for new protective clothing, but very little data on used or soiled clothing.    For respirators, NIOSH has collected data at ambient temperatures, but no data is available for high temperature exposures.   For respirator lenses, the current standard requires exposure in a 95 C oven, but no data for actual fire exposure conditions.  Lab- and full-scale tests will provide this data necessary to generate a comprehensive metric for the existing equipment.   For other existing technologies such as positive pressure fans and hose nozzles, the equipment is relatively simple, but the implementation is more complex.  Computer models and full-scale experiments generate the required data to allow performance metrics and usage guidelines to be developed

For emerging technology, there may be prototype systems, but the industry often has little understanding of the operating environment or requirements of the fire service.  The role of the AFST Program initially focuses on assisting the fire service and industry to characterize the operating conditions, and then collecting the necessary data to support representative performance metrics.   For locator/tracker technology, the industry tried to adapt existing technology including avalanche rescue, global position systems, and robotic pedometry.  Because there was no performance metric, each of these technologies claimed to have solved the fire fighter location and tracking problem.  As preliminary performance requirements were developed, the industry began to understand that fire fighters walk, crawl, and fall down in complex structures that often contain metal.  The range of movement, metal walls, and complex buildings defeated pedometry, GPS, and avalanche trackers, respectively.  The AFST Program will work with industry to examine hybrid systems which may employ multiple location technologies.  For the structural collapse predictor, an emerging tactical decision aid, preliminary full-scale field tests demonstrated vibration monitors did provide a useful signal, but further validation and assessment of reliability is needed.  Industry will utilize NIST science-based performance metrics to evaluate and improve their own products and develop new technology.

For both existing and emerging technologies, it is critical that the technology be successfully transferred to the fire service through computer model simulations, virtual training programs and science-based training materials.  

Why can we succeed now   In the past, the fire service has depended on gaining experience by responding to a large number of fires.   But, as the overall number of fires decrease and the more experienced fire fighters and officers retire, they are being replaced with younger, less experienced personnel who are more accepting of new and innovative technology.  In addition to a fire service that is more receptive to new technology, more technology such as tactical decision aids, and locator/trackers are just being developed.   Other technologies, including protective clothing and respirators, have seen recent progress in performance predictive modeling.   AFST program staff have the lab- and full-scale experimental experience and the computer modeling abilities necessary to develop the required performance metrics and standard testing protocols to evaluate existing technology, integrate new technology, and provide simulations and training programs

What is the research plan   The research plan includes two components that focus on developing measurement science existing and emerging technologies while a third component is directed at fire fighter simulators and training programs.  The allocation of effort between these three components was guided by the anticipated impact of each component on reducing fire fighter injuries and fatalities.  Within the each component, project selection was guided by anticipated impact as well as prioritization by the stakeholders

Approximately half of the effort is focused on providing the science that supports the development of performance metrics, standards, and testing protocols for existing equipment and technology

Respirators – Create computer generated simulation of internal flows during a breathing cycle with a leak. (Q1 FY2011), Generate database of temperature profiles for respirators at thermal fluxes from ambient to 5 kW/m2 from lab-scale exposures (Q3 FY2011), and metrics & sensor location to NFPA Respiratory Protection Equipment Committee[9] (2011)

  • Protective Clothing – “dark side” stressing of all outer shells at 5 C and 50% relative humidity.  (Q1 FY2011), Complete install and validation of thermal performance testing tools. (Q2 FY2011), and develop draft aging performance standard to NFPA Structural and Proximity Fire Fighting Protective Clothing and Equipment  Committee[10] (2011)
  • Hose Stream Effectiveness – Complete full-scale fire experiments documenting gas cooling effects of hose streams in a multi-compartment structure (Q2 FY2011), complete validation of hose stream models and complete summary NIST TN and archival articles on the results of the study. (Q4 FY2011), and provide results to NFPA Fire Suppression Committees[11], [12] (2012)
  • Performance Metrics of Critical Electronic Equipment – Modifications to the flow loop setup and testing procedures completed for securing the speaker microphones and measuring the signals. (Q1 FY2011), flow loop modified to simulate smoke and water vapor conditions, and provide recommendations to NFPA Electronic Safety Equipment[13] (2011)
  • Fire and Chemical Environment- Complete tube furnace experiments of fuels (particleboard, hardwood, Excelsior, and wood pallets) (Q1 FY2011), Complete spectroscopic measurements of gear to measure the amount and type of combustion products and deterioration of performance or polymer(Q2 FY2011), and provide recommendations to NFPA 1403 Live Fire Training(2012)

About forty percent of the effort is applied to exploit emerging innovative technology in order to allow the fire service to quickly take advantage of new technology and/or the information rich environment

  • Emergency responder/occupant locators – Repor on results of FY10 workshop on evaluation of first responder locating systems(Q1 FY2011), develop and demonstrate a method for non-line-of-sight ground truth tracking for evaluating the performance of first responder locating systems. (Q3 FY2011), and produce tools for locating occupants in emergency events (2012)
  • Tactical decision aidsDevelop prioritization criteria for the types of information needed to alert emergency responders to critical situations in residential buildings (Q1 FY2011), document the use of structural monitoring devices as a test case for a situational awareness tool (Q4 FY2011), and provide results to NFPA Electronic Safety Equipment Committee (2013). 

The remaining ten percent of the effort is directed at fire fighting simulators and training programs to insure that the above science and technology can be successfully transferred in a usable form to the fire service

  • report comparing FDS simulations with townhouse fire dat (Q2 FY2011), analyze data from UL fire/ventilation experiments with both a two story colonial style home and a one story ranch style home (Q4 FY2011), complete a suite of interactive training modules for three different types of residential structures based on full-scale data (2011)

How will teamwork be ensured   The Program involves staff from 3 of the 4 groups in the Fire Research Division, from BFRL’s Construction Metrology & Automation Group, and from EEEL’s Electromagnetics Division (Boulder).  A series of communications were conducted with staff on program direction and project milestones through e-mail and individual discussions.  Interaction between team members will be encouraged through informal and formal sharing of project results through individual meetings coordinated by the Program Manager, through information sharing at BFRL Seminars, and through team meetings. 

What is the impact if successful   Over 1.3 million fire fighters will have better access to proven technology and this will allow them to operate more safely and more effectively on the fire ground.   Over the next five years, this enhanced operational effectiveness on the fire ground is aimed at reducing fire fighter injuries and fatalities by 25%, as well as reducing property losses by 5%.  Fire fighting technology developers and manufacturers will have a proven set of performance metrics, standards, and testing protocols for evaluating existing technology and developing new technology.   Because the standards will provide a uniform, unbiased, and science-based evaluation, this will encourage improving current equipment and foster the creation of the next generation of technology. Some specific examples are given below

  • Improvements to the respiratory protection of emergency responders will be enabled by the development of modeling tools, experiments, and instrumentation to characterize the environments internal and external to a fire fighter’s respiratory mas
  • Fire fighter/occupant locator systems offer the ability to track emergency responders and occupants inside structures.  Draft performance metrics and testing protocols will allow industry to develop technology that is responsive to fire service needs. 
  • Fire and chemical environment at the fire scene will be characterized to better understand the exposure of fire fighters, arson investigators, and building occupants, which will enable solutions to prevent adverse health effects
  • Tactical decision aids including structural integrity will create a basis for more informed emergency responders and better and safer response to emergencies in buildings. 
  • Hose streams will be characterized, performance metrics will be developed, and testing methods evaluated and this will enable more effective extinguishment of fires
  • Accessible training tools, including release of Smokeview 6 that accurately represent fire environments and actions will improve training for firefighters
  • Science-based standards for thermal imaging cameras, respirators, protective clothing, locator/tracking systems, and tactical decision aids will allow performance to be evaluated and will enable development of innovative technology
  • Based on NIST measurement science on building panels, National Electrical Manufacturers Association (NEMA) and/or National Fire Protection Association (NFPA) will be able to adopt standard format and prioritization of displays,  which will enable the fire service to access and exploit building information for tactical decisions

How will knowledge transfer be achieved?  Knowledge and results from the program will be disseminated to customers and stakeholders through archival journal articles, conference proceedings (papers & posters),  CD/DVD media,[14] web sites,[15] reports on the web through BFRL’s Research Information Service[16] downloadable software[17] and participation in fire service  conferences,[18] technical conferences,[19] workshops, standards[20], codes, and technical committee meetings.   Guest workers from the fire service and authorities having jurisdiction (AHJ) and post-docs from universities will allow exchange of experience and knowledge. Customer and stakeholder feedback continues to be monitored by the Program Manage and ey stakeholders are supportive of NIST research.  NIOSH National Personal Protective Technology Laboratory is supportive of high temperature exposure metrics for respirators and improved testing protocols for PASS device alarm signal performance.  IAFF is supportive of research involving improved protective clothing.  IAFC is supportive of the work to transfer research results to the fire service via FIRE.GOV.  NFPA has been collaborating with BFRL on positive pressure ventilation, protective clothing, thermal imaging cameras, and high temperature exposure of radios and respiratory masks.

Recognition of BFRL:   The projects of AFST provide BFRL with high visibility within the fire service community because the projects get BFRL research directly into the hands of our stakeholders, in particular, the fire service, fire protection engineers, standards development organizations, and fire equipment manufacturers.  The positive pressure ventilation work was reported on local TV (Chicago and NY) and national networks (ABC & FOX).  Positive pressure ventilation research has also been on the web at Firehouse.com and FireEngineering.com.  Burn pattern research results have been highlighted in presentations on www.cfitrainer.net/.  BFRL has taken a leadership role that is recognized internationally for technology and standards that will enable the transfer of emergency information from buildings to the fire service.  This role may be expanded through DHS funding to the greater public safety community.  BFRL’s work to develop measurement standards for thermal imagers is the only known effort for thermal imagers focused on addressing firefighter needs in the world.
