Results show that significantly worse conditions are induced by multiple sources than those in a single fire of equal power. The data was used in the determination of the smoke layer interface height, with the least-square and the n-percent methods. Temperature measurements in the plume and close to the walls have been recorded using 59 thermocouples.
