  24. 24. • TB 117:Twelve second small open flame and smolderstandard for filling materials used in upholsteredfurniture.CALIFORNIA FURNITURE FLAMMABILITY STANDARDS
  25. 25. Home fires that began with upholstered furniture, NFPA, Aherns, Aug 2011Smoking materials cause the most fire deathsSmoking materials(addressed by smolder standard)Candles, lighters, matches(addressed by TB117)U.S. civilian deaths from home upholstered furniture fires,1980-2009
  26. 26. Smolder vs. open flame firesSmolder fires• The majority, relatively easy to prevent• Flame retardants not needed to meet smolderstandardsOpen flame fires• Small number, difficult to prevent• TB117 impacts:– no significant fire safety benefit– global PentaBDE contamination
  27. 27. :Monday, June 18, 2012California State Agencies Directed to ChangeOpen Flame StandardTB117-2013– Smolder standards for fabric– Increased fire safety without flame retardants– 85% of fabrics already pass– 15% need to have a layer of non-FR polyesterbatting between fabric and foam
  28. 28. • TB 133:Severe flammability test procedure forcomposite testing of seating furniture for use inpublic occupancies.Currently cannot be economically met withoutflame retardant chemicals in the fabric, thefoam and/ or in the barriers

  30. 30. Can Furniture Flammability Standards in othercountries provide a model?• Smolder standard in the EU, outside theUK, are met without flame retardants.• Open flame standards in California and theUK have led to high levels of flameretardants in dust and humans.Significant fire safety benefit?• Smolder standards such as 16CFR1634can increase fire safety without flameretardant chemicals
  31. 31. Toolbox for Fire Safety• Decrease in smoking• Smoke detectors• Preventing ignition: Fire safe cigarettes,candles, and lighters• Sprinklers• Fire Codes• Fire safety education• Furniture flammability regulations:– Smolder: TB117-2013 and 16CFR1634– Open flame “Barrier” standardBenefit and harm for interventions?
