• Description:
  Characteristics of smoke particulates generated from a wood fire in a ventilated model tunnel were investigated using an in situ optical and a grid sampling technique. Volume-to-surface mean diameter and mass concentration of the smoke particles, and the transmission, optical density per unit length, and particulate optical density of the smokeladen exhaust gas were obtained as a function of the burning process in the tunnel. It was found that high concentrations of smoke were rapidly generated as the fire changed from oxygen-rich to fuel-rich burning, resulting in fast obscuration of the passageway. The simultaneous generation of large amounts of smoke and high temperature carbon monoxide coupled with the low transmission represents an extremely hazardous situation in such a fire environment. Present measurements and others from current smoke testing chambers are compared and discussed. [Description provided by NIOSH]
