Physiological effects of combustion products and fire hazard assessment by Professor David A. Purser Hartford Environmental Research, UK
The target of this paper is to provide scientific bases to the statement (manifest, but generic) that the main cause of injury and death in fires is incapacitation resulting from exposure to fire effluent (smoke and gases). During fires, physiological effects dominate and determine time to incapacitation. The sequence of physiological hazards in developing fires can be applied to fire safety engineering design of buildings and to the evaluation of products for use in them using appropriate calculation methods for assessment of time to incapacitation.
