Mass fires are being investigated through a series of large-scale test fires. Preliminary results indicate: (a) air flow patterns that create eddies can result in fire vortices when fires is present; (b) the lower part of the convection column consists of a series of small columns that merge well above the combustion zone; (c) air flow for combustion in a large fire may come from a relatively deep layer around and above the fire; (d) flame temperatures are much higher than in small experimental or laboratory fires; and (e) noxious gases occur within, and adjacent to the fire with no significant concentration in the area between fires when fires are spaced 115 feet or more apart.
