Determination of induction time in multi-fuels combustible systems are discussed: using of global kinetic schema of elementary reactions and using of approximate equation for average reaction of induction time. Both types of data for induction time are used for prediction of detonation cell size and critical initiation energy for hydrogen-air mixtures with addition of ozone and hydrogen peroxide. The cell size was calculated with the help of Computer Program "SAFETY". Calculated results are compared with experimental data. It is shown that small additives of ozone and hydrogen peroxide to hydrogen-air mixtures result in a shortening of the induction-zone length over the entire range of the initial H 2 concentrations. The comparative increase in the detonatability of the mixture in the presence of O 3 or H 2O 2 displays a substantially nonmonotonic nature.

Key words: detonation, explosive, hazard, induction time
