Abstract:

We are primarily discussing fires that occur in buildings and under 'normal' conditions. But, clearly, some fires of great concern may not be in buildings; these include fires in submarines, spacecraft, and the like. The prevailing conditions will then, most likely, also be different for such fires. The variables which may be altered include: oxygen concentration in the combustion air; the temperature of the incoming combustion air; the presence of additional gases not occurring in normal air; total pressure; wind blowing across the burning object; relative humidity; and, the acceleration of gravity.
