  • To evaluate the hazard of gaseous epoxypropane-air explosions, characteristic parameters of gaseous epoxypropane explosion inside 5 L-sphere closed vessel with 40% and 88% relative humidity were measured. The obtained results show that: Maximum overpressures reduce slightly at near optimum explosion concentration, the others make no difference; a major influence of the initial humidity on maximum rates of pressure rise is observed only at 7.0% in the examined ranges of the gaseous epoxypropane concentrations; and the maximum temperature and the maximum rates of temperature rise are slightly influenced by the initial humidity.
