Summary
Walking speed in non-irritant and irritant smoke against the extinction coefficient of the smoke. Based on Purser (2002), p. 2-118, and Australian Building Codes Board (2020), p. 282.
Original illustration for Fractional effective concentration, level 4 Expert.
- Source basis: Purser (2002), p. 2-118 (Table 2-6.10 and text on Jin's experiments, speed as in darkness); Australian Building Codes Board (2020), p. 282 (Table 23 derived from Jin). Redraw from the tables; do not copy Figure 2-6.22 (p. 2-118).
- Alt text: Chart of walking speed against smoke density: speed in irritant smoke drops to 0.3 m/s at a much lower density than in non-irritant smoke.
