Results

• Cone calorimeter/FTIR data for flaming and
  smoldering resin blocks.
• Gas concentrations for flaming and smoldering
  resin blocks in center of 707 cargo compartment.
• Smoke levels from flaming resin block in main
  deck DC-10 cargo compartment.
• Detection times for flaming and smoldering resin
  blocks in below floor DC-10 cargo compartment.

Future Activities

• Complete resin block testing in DC-10 below floor
  compartment.
• Run a variety of fires in DC-10 (alcohol soaked
  rags, suitcases, shredded newspaper).
• Develop possible alarm algorithms and compare
  detection times for the above fires and resin
  blocks for both the 707 tests and the DC-10 tests.
