As part of the DHS/AFG grant project, “Study of the Fire Service Training Environment: Safety, Fidelity, and Exposure,” twelve full-scale fire experiments were conducted within an acquired test structure using two common training fuel packages: 1) pallets, and 2) pallets and oriented strand board (OSB). To compare the training fuels to modern furnishings, the experiments conducted were designed to replicate fire, ventilation location, and event timing to the prior research:

whatshot Impact of Ventilation of Fire Behavior in Legacy and Contemporary Residential Construction
whatshot Effectiveness of Fire Service Vertical Ventilation and Suppression Tactics
whatshot Effectiveness of Fire Service Positive Pressure Ventilation

Below are images of the two training fuel packages used in these experiments. On the left is the setup of pallets for a living room fire. On the right are pallets and oriented strand board setup for a bedroom fire.



Main Objectives:

  • Compare the fire dynamics of a furnished structure with the fire dynamics of an acquired structure with NFPA 1403 compliant fuels.
  • Identify the extent to which tactical considerations from previous research projects can be replicated for training using NFPA 1403 compliant fuels.
  • Quantify the thermal environment inside live fire acquired structure burns produced by NFPA 1403 compliant fuels.


  • With the appropriate context, live fire training in acquired structures with NFPA 1403 compliant fuels can be used to train on many of the tactical considerations from the previous Horizontal, Vertical, and Positive Pressure Ventilation projects.
  • Acquired structure fires with NFPA 1403 compliant fuels do not completely mirror interior conditions produced by modern furnishings.
