AbstractAnimal experiments have been used by Pryor et al in investigating the hazard connected with combinations of toxic gases (CO and CO[2]), oxygen depletion, and high temperature that may occur at fires. They report finding a synergistic effect with some combinations. The authors of the present paper have examined their data in the light of statistical techniques whereby synergistic or antagonistic effects are detected as interaction of factors and have found that the effect of combinations of factors is generally additive. Some of the data involving combinations of O[2] and CO, O[2] and temperature, CO and temperature, and CO[2] and temperature indicated possible synergism. Variance analysis showed that the effect of interactions of pairs of factors was minor in comparison with that of the main factors.
