Good evening. Ethyl acetate may explode when it is directly volatilized and fully mixed with oxygen in the air, but it is generally safe as long as it does not encounter a fire source or a strong oxidation reaction. Ethyl acetate is similar to butyl acetate as a paint thinner, and it needs a high saturation concentration to be dangerous. Please refer to it. As for the extent of explosion, there is no specific numerical value to verify, but its calorific value is about half that of isooctane in gasoline, and its actual power is much smaller as long as it is not in a closed space.
