Live Fire Experiments Provide Data on the Effects of Staffing, Resources

NIST Official Release

ROCKVILLE, Md.— At a live demonstration of fire safety experiments today, a group of firefighting, public safety and scientific organizations described a landmark collaborative study examining the effect of firefighting crew sizes and equipment arrival times on fire growth rates and a person’s ability to survive in a structure-related building fire.

Funded by the U.S. Department of Homeland Security (DHS), this firefighter safety and resource deployment study will help governments make informed decisions to better match resources with risks to the public and firefighters in their communities.

“This is a study many fire industry leaders have dreamed of for several years,” says Chief Dennis Compton of the International Fire Service Training Association, a technical advisor to the project. “Until now, it has simply not been possible, due to the complexity of the tasks proposed and the costs involved.”

A broad coalition is participating in the study, including (in alphabetical order): Center for Public Safety Excellence; Commerce Department’s National Institute of Standards and Technology (NIST); Fairfax County (Va.) Fire and Rescue Department; International Association of Fire Chiefs; International Association of Fire Fighters; Montgomery County (Md.) Fire and Rescue Service; Urban Institute; and Worcester Polytechnic Institute. DHS has provided $1 million each for the two years of research through the Federal Emergency Management Agency’s Assistance to Firefighters Grant Program.

Fire is a costly problem in our communities in both lives and property. According to the National Fire Protection Association, in 2007 there were 530,500 structure fires that killed 3,000 civilians and injured more than 15,000, while causing $10.6 billion in property damage. About 100 firefighters die in the United States each year, with 9/11 being the exception, and many more are injured.

Predicting the effects of changes to fire service resources is critical to fire service and local government leaders. “Currently local governments rely on trial and error or a qualitative basis,” explains NIST researcher Jason Averill. “When this study is complete, there will be objective data on which to base these important decisions.”

The study focuses on the effects of crew size (two, three, four and five persons per fire engine) and apparatus arrival time (all engines/trucks arrive close together or arrive at longer intervals) on the fire conditions within one 2,000-square-foot, two-story home specially built to survive multiple fire conditions. This “burn house” has been instrumented with state-of-the-art equipment to monitor the interior temperatures and toxic gas build-up within the structure. In addition, researchers will monitor 22 different tasks at the firefighting site, or “fireground.”

“NIST has a long history of working with the fire service, and these experiments continue this important tradition,” says Shyam Sunder, director of NIST’s Building and Fire Research Laboratory. “With NIST’s expertise in measurement science, we aim to deliver reliable, accurate and timely data that local governments can use to maximize fire safety in their communities consistent with the risks that they face.”

“The information gained from this study will have an immediate and direct impact on how we respond to fires and other emergencies in our communities. Not only will this study provide scientific data to help local government decision makers with establishing an effective firefighting force, resource allocation and community risk assessment, it will furnish fire and emergency service leaders with the tools for a more efficient response to fire and EMS emergencies,” says Montgomery County Fire and Rescue Service Acting Fire Chief Richard Bowers. “This study will help make our businesses and communities safer places to live, work and enjoy.”

The results from these fireground experiments will complement a fire incident survey involving 400 fire departments from across the country. Together, these two parts of the study will provide an overview of the incident outcomes, along with a detailed understanding of fireground effectiveness. If a third year of funding is awarded, the researchers will develop and validate a computer model that will allow local government decision makers to conduct “what if” analyses in order to help them make informed choices about the deployment of resources for public and firefighter safety.

“The International Association of Fire Chiefs views this study as critical to our assessment of community risks and resources in tough economic times,” says Mark Light, CAE, executive director of the International Association of Fire Chiefs. “The outcomes of this study will give fire and emergency service leaders an important new tool as we determine resource allocation.”

A full report is expected to be available in fall 2009.

About 50 firefighters from Montgomery County, Md., and Fairfax County, Va. participated each day in the experiments on the fireground at the Montgomery County Fire Rescue Training Center in Rockville, Md.



NIST is contributing its expertise in measurement science to national fire safety experiments examining the effects of firefighting crew size and equipment arrival times on fire response. Data from these experiments will help governments make informed decisions to better match their resources with the risks to the public and firefighters in their communities.

“The data provided by this multi-agency initiative will help stem the tide of firefighter deaths and make the general public safer,” said Chief Ronald L. Mastin of the Fairfax County Fire and Rescue Department. “Our firefighters are privileged and honored to participate in this effort.”

As an agency of the U.S. Department of Commerce, NIST promotes U.S. innovation and industrial competitiveness by advancing measurement science, standards and technology in ways that enhance economic security and improve our quality of life.

Glad they did something.
It will be most interesting to see the outcome of this and finally have something concrete to counter the many penny-wise and dollar-foolish decisions we see today. The recent article on Fairbanks, AK with on-duty staffing of 9 for fire and EMS (and the ignorance displayed by many local residents) is one case in point. The gross understaffing I hear of in many New England municipalities is another. At the opposite end of the spectrum, the closest career department to me routinely sends not less than 22 personnel to a structure fire. Managers and politicians need to be educated as to what we can and can't do with various staffing levels, and to realize that while they may get away with cuts for a while, they will sooner or later have devastating consequences. This study is long overdue.
I am from a strick volunteer dept. and the town is growing very quickly around us. I can't wait to see what they have to say about staffing levels and responding times due to the fact that we are looking at adding full time people very soon due to growth and this study should help show that.
I don’t think anyone can dispute the fact that larger crews or more responding crews can produce a more positive outcome on an emergency situation. The problem of money will always continue to be the problem. Throughout history the fire service has been seen “waiting” for the fire before they go to work. Most of the time the public only sees the firefighter in a regulatory fashion trying to enforce fire codes for the safety of the public. Of course, if violations of the codes or correction of such violations cost the property owner money than the fire dept. will be seen as the “bad guy”. Only after a structure has started burning does the public see the firefighters “work”. After over 38 years and 4 departments, paid, vollie and combo, I don’t hold hope for much change in the mindset of the general public. This is why it is imperative that we, the fire service, continue to try to promote ourselves as a valuable commodity to the community. This is done by more than just holding fund raising dinners or collecting money at the intersections. While our response volume is quite low, we provide an array of fire service and haz-mat related training and services to our taxpayers. This keeps us in a favorable light. I truly wish that I had 3 or 4 man crews on each of my trucks. Unfortunately, the current economic situation is making it hard for everyone. Our board of commissioners are not taxpaying homeowners. They are business leaders that must keep costs to a minimum. Yet, they continue to try to make sure that we have state of the art equipment. I’m not sure that we will ever see the manpower that we wish we had but we will continue to try to promote ourselves to prove our necessity. This is the only way that the general public will see our worth on a daily basis.

While I enjoy reading these types of forums, I generally don’t contribute to them because of the internet flames. I hope I haven’t stepped into the fire this time.
I just read up on what you mentioned about Fairbanks, AK. And all I can say is WTF!?!?!?!
yes mike i know where you are coming from, it's from the fire prevention side and can and should include ISO ratings which will include staffing. see how it all connects. i do belive you are right though the penny pinchers will wait till it happens before they jerk the knee and try and fix it and if you wait to long after the fact it won't get fixed then because the emergency has wore off. ask on the street about 9/11 and you don't have the anger and resentment as you did 2 weeks after the fact. my hats off to those that answer the call no matter the odds and give it their best and sometimes their all and know that more could be done. God bless all./
Wow, Here we go. Most likely just one more thing the powers to be can pretend does not exist or choose not to recognize as fact.
