- Abstract
- Early in 1958, a number of controlled burning experiments were carried out at Aultsville, Ontario, by the Fire Section of the Division of Building Research, National Research Council. The general details of these experiments, which involved the burning of six dwellings and two larger buildings, are described in the first of a series of reports published on the St. Lawrence Burns. It was the purpose of these tests to study the development of fire in buildings and to determine, among other things, how rapidly a fire originating on the ground floor of a dwelling could affect the survival of occupants of upstairs bedrooms. The factors which have the most influence on the time during which such survival would remain a possibility are the heat dissipated during the fire and the vitiation of the atmosphere, either through the accumulation of smoke or through changes in the air composition. Measurements of temperatures at various points inside the dwellings and of smoke density in the bedrooms and cellar have already been reported. This report describes that part of the operation concerned with the determination of oxygen and carbon monoxide concentrations in the two upstairs bedrooms (one with the door open and the other with the door closed) and in the cellar of each of the six dwellings. Plan views show the location of the two bedrooms in each of the dwellings.
