Purpose:
This attachment provides supporting information describing the heat release rate (HRR) profile (HRR versus time curve) parameters and HRR gamma distribution parameters for various fixed and transient ignition sources. The profiles and distribution parameters were used to develop the tables and plots in sets A, D, and E of Attachment 8 to the Fire Protection Significance Determination Process (SDP), IMC 0609 Appendix F. These tables and plots allow the analyst to look up the vertical and radial zone of influence (ZOI) (used in Step 2.3.2), severity factor (SF) (used in Step 2.6.1), and damage time (used in Step 2.7.1) for a specified fixed or transient ignition source, target type, and target location for fire damage state 1 (FDS1) scenarios. Guidance is also provided for determining the HRR of confined and unconfined oil fires, cable tray fires, and hot work fires.
