Short title	Times to 1 MW: ultrafast 75, fast 150, medium 300 and slow 600 seconds.
Image title	Horizontal bar chart of the characteristic time for a t-squared design fire to reach 1 MW, on a linear axis from 0 to 650 s: ultrafast 75 s, fast 150 s, medium 300 s, slow 600 s. These are design-fire categories, not fire durations or times to flashover.
