Table 2 Example of a heat and flame vector analysis legend
Vector | Material | Effect | Fire patterns analysis |
|---|---|---|---|
1 | Gypsum wallboard | Clean burn | Clean burn extending from doorway 5’ into compartment. Indicating intensity near the doorway. |
2 | Gypsum wallboard | Color change | Increasing line of demarcation moving down hallway. Indicating fire travel from living room down the hallway. |
3 | Gypsum wallboard | Clean burn | Clean burn extending from doorway to loveseat. Indicating intensity near doorway. |
4 | PU foam | Loss of mass | Backrest cushion completely consumed, horizontal cushion still present. Near uniform heat from top down, indicating a hot gas layer generated pattern. |
5 | Gypsum wallboard | Depth of calcination | Deeper calcination measurements in S corner of east wall. Indicating fire travel from S end of room towards N. |
6 | Wood | Char; depth of char | Greater visible and measurable char near sofa. Indicating fire travel from sofa. |
7 | Wood | Char; depth of char | Greater visible and measurable char near sofa. Indicating fire travel from sofa. |
8 | Wood | Char; depth of char | Greater visible and measurable char near sofa. Indicating fire travel from sofa. |
9 | PU foam/wood | Loss of mass; char | Greater char and loss of mass in center of sofa. Indicating fire travel from sofa. |
10 | Gypsum wallboard | Clean burn; depth of calcination | Greatest area of clean burn and depth of calcination above and behind center of sofa. Indicating fire travel from sofa. |
