2. The Revolution in Building Materials Plastics - Innovation or Ignition?

3. Outline The Use of Plastics Regulatory Oversight Flammability Testing Flame Retardants Steps for Successful Subrogation

4. Plastics Organic substances of large molecular weight Many shapes and combinations Wide range of uses – Appliances – Building materials – Insulators – Automotive – Textiles – Furniture

5. Growth in Plastic Use Maybe you have a better example of this that dates farther back

6. Regulatory Oversight Initial investigations focus on health, environmental, and mechanical performance Fire performance of plastic materials is secondary – Various government agencies Federal (CPSC) State and local (Fire Marshal) – Various Approval Agencies Underwriters Laboratory (UL) National Fire Protection Association (NFPA) – Decentralized enforcement of fire performance – Rapidly evolving uses not contemplated – Reactive regulations

The Start of Building Construction Regulation Incidents prompted development and adoption of Building and Fire codes – Regulated construction methods, materials, interior finish, furnishings – Required life safety and egress features – Required fire sprinkler protection Standardized fire testing of interior finish, building materials, and furnishings

9. U.S. Fire Problem A Snapshot of 2005 Estimated 511,00 structure fires $10 billion in direct property loss (excluding indirect loss and not adjusted for inflation) 80% of fires occur in residential properties (1- and 2-family dwellings and apartments) A structure fire occurs at a rate of 1 per minute 3675 civilian fire deaths Source: National Fire Protection Association, “Fire Loss in the U.S. 2005”, September 2006.

10. Station Night Club Fire A fire at The Station Nightclub (West Warwick, RI) on February 20, 2003, killed 100 people. Fire broke through the roof in less than 5 minutes 1.
