Summary
Stratification of smoke from a small fire below a warm air layer in a tall space; detection points at the ceiling may not see the smoke. Based on Schifiliti et al. (2002), p. 4-27, and Milke (2002b), p. 4-304.
Original vector illustration for Aspirating smoke detection, level 2 Intermediate.
- Source basis: Schifiliti et al. (2002), p. 4-27 (definition of stratification; example: 1,000 W fire, 10 °C difference, 7 m room, smoke rises to about 6 m); Milke (2002b), p. 4-304 (floor-to-ceiling differences about 50 °C in some atria with glazed ceilings; smoke stratifies below the warm layer; delays for ceiling-mounted devices)
- Alt text: Section of a tall space with a glazed roof: warm air under the roof, smoke from a small fire stops rising and spreads below the warm layer.
