Fire reduction strategies for residential furniture

  1. 1. Fire Reduction Strategiesfor Residential FurnitureApplicationsMike NagridgeDr. Sergei LevchikJoel TenneyDr. Mike GoodeGreg SymesDr. Anantha Desikan
  2. 2. Topics for Today1. Furniture Firestandard• Smolder• Open Flame• Component versusItem test methods2. Health, Safety andEnvironmentalproperties of flameretardants“One childs body was found in a bedroom of thesingle-story home just three feet from where oneof the firefighters had made it into the structure.The other child was found with her father justoutside of that room”
  3. 3. Fire Safety - Role of Flame Retardants•NFPA data showed smolder and open flame both similarlyimportant•NFPA data shows furniture fires are unique with respect tothe low frequency and high death rates•Transition from smolder to open flame not well understoodbut important•Furniture fires are still a problem and flame retardants are aproven solution
  4. 4. International Comparison of Fire Statistics• Out of 23 countries surveyed by FEMA, the top 4reductions in fire death rates between 1979 and 2007 were:– Canada -70.7%– UK -69.5%– USA -66.1%– Ireland -54.4%– Scandinavia -22.4%“Fire death rates and trends, an international perspective,” FEMA, July 2011The only 4 countries in the survey tohave introduced open flame standardduring the period-28% -6%Government study confirmedlinked to fire standard withlittle change in smoking over periodData from report ofUK Department forBusiness, Innovation and Skills
  5. 5. Open Flame Fire StandardsLarge Flame FAR Part 25.85316 CFR 1633Medium Flame BS 5852, Crib 5Cal TB133ASTM E2574CPSC 2007*Small Flame Cal TB117MVSS-302CPSC 2005Short Duration<15 secMedium Duration15-60secLong Duration>60 sec*Barrier test onlyFlame retardants are used successfully to meet all standards
  6. 6. Fire Safety - Role of Flame Retardants•People die in large fires when smoldering transitions to flaming•The ignition source of a smoldering object can be a cigarette, a sparkfrom fire place, etc•Very rarely do people suffocate because of smolder only scenario•The proposed CPSC smoldering standard does not addresstransition from smoldering to flame because it is performedwithout air draft•Not representative of real life•(open windows, running ceiling fan etc.)•Independent of ignition source (flame or smoldering), the goalmust be to prevent ignition and fire growth
  7. 7. Polyurethane Flame Retardant Options– Reactive– Polymeric– Flame Retardant Polyols– Solid Inorganics– Additive
  8. 8. Flame Retardants• Fyrol® 6 (1963)– Reactive• Fyrol® PNX / PNX-LE (2003)– Polymeric, highly efficient• Fyrol® A710 / HF-4 (2005)– Additive TBPP• Fyrol® HF-5 (2010)– Additive/PolymericNew Products under developmentE08-16T/E10-61T – additive solutionsE10-62T – reactive solution
  9. 9. Health, Safety, and Environment• Flame retardants are already reviewed in the regionsincluding the US, Canada, EU, and Asia• Flame retardants used in imported furniture are not required tomeet US review (TSCA) requirements• Additional reviews are underway• EPA – 20• Canada – 10• California Safer Products• Third party (Environ) evaluations indicate Fyrol A710and Fyrol HF-5 show improved HSE versus TDCP• New methodologies are being utilized• Zebra fish tests• Exposure Routes– Work done in Europe (Fisk „05), EPA, CPSC, Duke University (2012)
