Evaluation and Development of a Novel Fire Barrier for Upholstered Furniture Enhancing Passive Fire Protection and the Mitigation of Chemical Exposure

ABSTRACT This study evaluates the effectiveness of fire barrier solutions for upholstered furniture to enhance passive fire protection and reduce chemical exposure risks during regular use. Upholstered furniture ignition accounts for 22% of fatalities in reported home fires, often due to rapid flame spread and high heat conditions. Given the substantial fuel load presented by upholstered furniture, implementing targeted fire protection strategies to limit fire growth and spread is critical in helping to reduce fatalities. Research suggests that incorporating a fire barrier between the foam cushion and outer textile can delay foam ignition without requiring added flame retardants. This approach not only improves fire safety but also mitigates concerns about chemical exposure from flame retardants detected in dust, air, and burn emissions. This comparative study assessed upholstered cushions with and without a fire barrier using standardized testing methods, including the Smolder Test, elemental analysis, flame retardant testing, and a small‐scale open flame test. Sixteen commercially available barriers were initially evaluated but were eliminated due to deficient performance. A novel fire barrier, developed in collaboration with a fabricator, was tested and found to meet flammability and chemical safety criteria. Full‐scale open flame testing of upholstered cushions revealed that those without a fire barrier burned completely, while those with the barrier textile prevented foam combustion, exhibiting only minimal smoldering. These findings demonstrate that using a fire barrier on upholstered furniture offers an effective solution for reducing fire risks without increasing chemical exposure and highlights an integrated approach to improving fire safety and health outcomes in residential environments.
