| Research Abstract |
The mixture conditions of fire retardant chemicals effective for reduction of heat release property and gas toxicity of wood were examined. Moreover, the relation between the carbon monoxide concentration in combustion gas and gas toxicity was investigated.
The mixture ratio of phosphorus compounds and sodium octaborate effective for decreasing heat release was nine to one. Furthermore, these fire retardant chemicals reduced carbon monoxide concentration and gas toxicity based on combustion gas toxicity test. On the other hand, the relation between carbon monoxide concentration and gas detrimental nature was not obtained.
