If it doesn't burn, they say, then there won't be a fire. In more practical terms for the modern built environment, a new National Institute of Standards and Technology roadmap pres- ents a strategy to reduce the thousands of deaths and injuries and billions of dollars in damage resulting from the more than a million fires each year in the United States. Authors offer guidelines for developing sci- ence-based approaches to solving numerous fire problems for multiple materials, from upholstered furniture to lightweight automo- bile composites to cross-laminated timbers, and prioritize the most critical and urgent fire hazards to which they can be applied. "Our hope is that this roadmap will help the global fire community develop research strategies and implementation plans for addressing fire and materials problems, now Fire hazard reduction roadmap stresses flammable materials minimization and in the future," says co-author and NIST Materials Research Engineer Rick Davis. "The roadmap describes the major challenges associated with these problems and then details potential solutions so that users such as designers and manufacturers can continue to create safer materials that still yield qual- ity products with high consumer satisfaction and market profitability." The document resulted from a recent NIST-led workshop that brought together key national and international stakeholders from industry, government, academia and public laboratories. Participants focused their discussions on four areas in which fire hazards are major concerns: Innovative construction materials such as the growing use of cross-laminated wood for tall build- ings; advanced polymers and composites such as polyester fabrics used in furniture; lightweight composites used in automobile bodies; next-generation fire retardants, with an emphasis on those that suppress com- bustion without being health hazards; plus, transportation and infrastructure vulnerabil- ities such as fire risks on trains. For each area, the experts considered the direction of current research & development and how it may impact future fire hazard reduction goals such as developing new materials, establishing product flammabil- ity standards and advancing computational tools. They also addressed emerging technol- ogies and practices like the increasing use of high-energy density (lithium-ion) batteries that have been in the news for flammability concerns. Workshop participants agreed that the highest priority for future scientific studies and development projects in flammability should be assigned to research addressing multiple hazards across a wide range of materials and applications: • Real fire behaviors: To understand how the actual use of a product impacts its fire ser- vice-life (the fire resistance over the life of a product) and burning behavior; • Engineered fire-safe products: To enable the development of technologies that yield products compliant with flammability regu- lations for their entire lifetime; and, • Bench-scale and computational tools: To develop and use physical testing meth- ods and computer modeling systems that accurately predict a material's real-life fire behavior. The NIST roadmap strongly recommends that these research approaches be applied to the five most critical and urgent fire hazards as defined by the experts at the workshop: Residential upholstered furniture; residen- tial buildings in Wildland Urban Interface communities; timber used for multistory buildings; passenger railway cars; and, insu- lation applied to high-rise building exteriors.
