 Although fires that start on furniture account for only 2.2% of
residential fires, they carry significantly higher odds than others
for injury and death, researchers report in the American Journal of
Public Health. And among these furniture fires, those ignited by
smoking materials are 3.4 times more likely to be lethal than those
caused by open flames like candles.
"The fire safety standards for furniture ought to address the most
dangerous types of furniture fires," said Kathryn Rodgers, a staff
scientist at Silent Spring Institute in Newton, Massachusetts, who
led the study.
Historically, furniture flammability regulations in the U.S.
targeted ignition from open flame heat sources, Rodgers told Reuters
Health by email. "However, in order to meet this standard,
manufacturers added toxic flame-retardant chemicals to furniture
foam, resulting in widespread exposures to these chemicals."
Regulations trace back to a 1975 California rule that, in the
absence of a national furniture flammability standard, became common
for residential furniture over time, the study team writes. The rule
required the interior filling of furniture to withstand an open
flame for 12 seconds before igniting. Since then, however, flame
retardants have been associated with serious health concerns such as
cancer, neurotoxicity and reproductive and developmental issues.
In 2017, the Consumer Product Safety Commission voted in favor of a
rule to ban certain flame retardants from upholstered furniture,
mattresses, children's products and electronic casings.
To gauge the effect of the longstanding open-flame standard on
deaths in furniture-related household fires, Rodgers and colleagues
analyzed death and injury data from 34,000 residential fires in the
Massachusetts Fire Incident Reporting System from 2003 to 2016.
They compared the outcomes from fires that started on upholstered
furniture ignited by smoking materials versus those ignited by open
flames. They also looked at smoke detector presence, fire spread,
season, time of day, and human-related factors such as age,
disability and intoxication when the fire started.
Among all the residential fires, 360 resulted in deaths, 565 had
severe injuries and 2,246 had less-severe injuries. Of the fires
resulting in death, 95, or 26%, involved smoking materials as a heat
source, as compared with 30 fires, or 8%, started by open flames.

Among the 50 deaths involving fires that started on upholstered
furniture, 38 were caused by smoking materials, as compared with 4
started by open flames.
The 733 furniture fires made up just over 2% of all residential
fires yet resulted in 14% of deaths, the study team notes. When a
furniture fire was started by smoking materials rather than open
flames, the odds of injury doubled and the odds of death more than
tripled, they calculate.
Injuries were also more likely when people didn't have a working
smoke detector, were intoxicated or had a disability.
"Manufacturers have been needlessly adding toxic chemicals to
furniture in order to address a risk that can be met with non-toxic
measures," Rodgers said. "Everyday exposure to flame retardants has
impacted the health of millions of Americans and resulted in
billions of dollars in healthcare costs."
The study team notes that Massachusetts saw a 28% reduction in the
odds of a home fire caused by cigarettes compared with fires started
by other causes after it implemented a fire-safe cigarette law in
2008 requiring cigarettes to extinguish themselves when not being
frequently inhaled.
The researchers also point to ongoing public health efforts to
reduce smoking overall as potentially more effective ways to target
smoking materials, rather than furniture, to reduce smoking-related
fires.
"Residential structure fires pose a significant risk to life and
property," said David Butry of the National Institute of Standards
and Technology in Gaithersburg, Maryland, who wasn't involved in the
study.
"In recent years, states have adopted fire standard compliant
cigarettes ('FSC cigarettes') that are made with a wrapping paper
that contains regularly-spaced bands, which increases the likelihood
of self-extinguishment," he said by email, noting that these seem to
be most effective at reducing fires in places with a lot of heavy
smokers.
