To examine the danger of explosion caused by decomposition explosion of Methyl Ethyl Ketone Peroxide, the mini cup pressure vessel tester (MCPVT) was used in the experiment. The maximum explosion pressure increased as the amount of $98\%H_2SO_4$ added to MEKPO increased from $0\%$ to $1\%,\;3\%$, and $5\%$, and the maximum pressure rising velocity increased as well. In addition, the temperature under the pressure at which decomposition starts decreased from $168.16^{\circ}C$ to $126.76^{\circ}C,\;91.21^{\circ}C$, and $81.25^{\circ}C$ as the amount of $H_2SO_4$ added increased.

In this study, the evaluate characteristics of fire and explosion of MEK-PO are subjected to spontaneous ignition, flash point and explosion hazard. The minimum ignition temperature and instantaneous ignition temperature for MEK-PO were $188.5^{\circ}C\;and\;230^{\circ}C\;at\;225{\mu}L$. In addition The flash point for MEK-PO was obtained at $49^{\circ}C$. Furthermore, the maximum explosion pressure and the maximum explosion pressure rising velocity: using MCPVT (mini cup pressure vessel tester) were $10.82kgf/cm^2\;and\;33.72kgf/cm^2{\cdot}s$.
