Toxic Gases Evolution from Air-Controlled Fires in a Semi-Full Scale Room

Fire experiments were conducted in a semi-full scale room equipped fully with combustibles corresponding to construction materials and other house contents under various air supply conditions. This paper describes toxic index Σ(C _i lC _fi ) vs. CO ₂ /CO ratio (C, : the concentration of gas component i, C _fi : its lethal or fatal concentration), volumes of air-diluted gases adjusted to lethal level per unit mass of fuel vs. air supply rate/mass burning rate, a comparison of CO and other toxicants in terms of toxicity, and a comparison of toxicity, oxygen deficiency and heat for potential lethal effects.
