ABSTRACT:
A method of controlling toxic outgassing of carbon impregnated polyurethane nd 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 duringburning to yield ammonium cyanide plus ammonium chloride which yields relatively harmless precipitates when cooled.
