Abstract:

Experiments were conducted with animals to determine the toxic effect of short-term exposures to some of the products produced in aircraft fires the products were tested both singly and in combination with carbon monoxide. These studies show the toxicity rankings of the four materials tested to be HCN, NO2, HF and HCl, in decreasing order. Carbon monoxide concentrations which alone are not hazardous to life do not enhance the toxic response to these substances.
