Smoke toxicity:yields of toxicants in fires and implications for lethality and incapacitation

摘要

this work presents some data on yields of common toxicants (combustion products) in fires and fire tests and analyzes the implications of those yields to consider lethality and incapacitation limit levels.Recent limits,based on incapacitation concepts,have been suggested and analysis of actual fire data indicates that it is essential to replace them by realistic criteria that do not require severe and unreasonable building contents limitations.This information will be combined with a toxic fire hazard assessment for those fires that cause the vast majority of fatalities:the ones reaching beyond the room of fire origin and associated with flashover.
