Abstract : This patent describes a method of controlling toxic outgassing of carbon impregnated polyurethane and other radio-frequency-absorbing materials when burning or smouldering. Ammonia gas and water or steam are sprayed onto smouldering material to combine with hydrogen cyanide (HCN) and hydrogen chloride (HCl) formed during-burning to yield ammonium cyanide plus ammonium chloride which yields relatively harmless precipitates when cooled.
