Within the Seventies, NASA researchers developed a tool that would detect smoke on an area station.
Whereas smoke alarms existed beforehand, they had been costly and huge.
After this development in know-how from NASA, hearth researchers at NIST (then generally known as the Nationwide Bureau of Requirements) wrote a paper about the right way to create requirements for these gadgets and drastically cut back their measurement and price.
That paper was shared with Underwriters Laboratories — the group that also units requirements for smoke alarms. This helped result in the smoke alarms we now have as we speak in properties and buildings which have saved numerous lives.
Across the similar time, Congress handed the Federal Hearth Prevention and Management Act of 1974, a regulation designed to create a unified authorities method to stopping and responding to fires. On the time, there have been greater than 6,000 hearth deaths per 12 months.
The Hearth Security Moon Shot
In 1976, John Lyons, who led NIST’s hearth analysis, set an bold purpose of decreasing hearth deaths by half inside a technology. This was the hearth equal of the race to the Moon.
“Many naysayers mentioned it might by no means occur,” mentioned Richard Gann, who spent almost all of his 52-year hearth science profession at NIST and is now a senior scientist emeritus. “It was particularly spectacular while you assume that homes final for much longer than 20 or 30 years, so constructing modifications take a very long time to have an impact. A few of these modifications concerned flammability of mattresses, and folks solely purchase new mattresses each seven to 10 years. It’s an extended haul between the analysis and the complete realization of the payoff.”
However due to authorities efforts, responsive product manufacturing and societal change, the U.S. met that purpose. Right now, hearth deaths nonetheless hover round half that quantity whereas the U.S. inhabitants has elevated by greater than 120 million.
Many elements contributed to the lower in hearth fatalities. Excessive on the checklist was smoke alarms being put in in almost all properties. One other cluster of things concerned cigarettes: a decline within the variety of People who smoked and laws that made cigarettes much less more likely to begin lethal fires.
Within the Nineteen Eighties, Gann led a examine that discovered it was potential to create a cigarette that was much less more likely to trigger furnishings and mattress fires. Additional NIST analysis over the following twenty years, together with legal guidelines that mandated much less fire-prone cigarettes, led to a 30% discount in cigarette-initiated hearth deaths within the U.S.
Burning Burgers to Construct a Higher Smoke Detector
Extra not too long ago, NIST researchers studied the sensitivity of house smoke alarms. The purpose is for the gadgets to detect fires extra precisely whereas recognizing the distinction between smoke from an precise hearth and smoke from cooking.
This concerned cooking meals — typically to a well-done state — in NIST’s hearth laboratories.
“NIST workers came upon that frozen hamburger patties had been critical offenders for setting off the detectors. They burned loads of hamburgers in our hearth lab,” Gann explains with amusing.
Smoke Alarm vs. Bacon
Researchers have shared this data with Underwriters Laboratory, and new necessities for smarter smoke alarms went into impact earlier this 12 months.
That is life-saving analysis as a result of each time somebody pulls a smoke alarm from a ceiling on account of a nuisance cooking alarm and doesn’t put it again, the detector can’t do its job.
NIST has made many main impacts over the past 50 years to enhance hearth security and save lives. As a part of the regulation’s anniversary remark this week, Gann and NIST’s Hearth Analysis Division have documented this historical past on NIST’s web site.
Measuring Hearth
NIST Hearth Analysis Division Chief Matthew Hoehler emphasizes that one in every of NIST’s important roles in hearth security is advancing the understanding of fireside conduct.

NIST hearth analysis gives important knowledge, enabling policymakers and business professionals to make knowledgeable choices on hearth security laws and insurance policies. NIST’s findings are used to replace constructing codes that mirror the newest hearth science.
“As a company, we’ve had a sustained focus for many years on giving individuals instruments to quantify hearth and its results on individuals, property and the surroundings. Within the absence of that data, you’re poking across the darkish,” Hoehler explains.
As wildfires turn into extra widespread and unfold into populated areas, NIST’s hearth researchers are more and more targeted on understanding a hearth’s influence on communities and sharing that data with different federal companies and the general public. Final 12 months, NIST launched reviews providing wildfire preparedness suggestions. This included steering for communities that wouldn’t have sufficient time to securely evacuate their residents.
“We’re not simply operating experiments, however we’re additionally within the area documenting the influence of wildfire on communities and growing new measurement know-how and strategies to grasp vital phenomena,” Hoehler mentioned.
Whereas wildfires are a scientific problem, NIST’s hearth researchers are decided to continue to learn the right way to assist us shield ourselves and our properties. The work does require a long-term perspective, as this analysis generally takes many years earlier than it impacts constructing codes or follow.
“You want perseverance while you work on this area, however we all know we’re impacting individuals in a manner that’s very direct,” Hoehler mentioned. “We’re making a distinction.”
