Ethyl acetate is flammable, and its flammability needs to be determined in detail. Guanfu ethyl acetate, at room temperature, is more active. Its molecular structure contains specific functional groups, which is the fundamental reason for its flammability.

When encountering energy sources such as open flames and hot topics, ethyl acetate molecules are energized, internal chemical bonds are active, and a violent oxidation reaction occurs rapidly. The flame jumps up, flashes, and releases a lot of heat energy at the same time. This combustion process, if in a limited space, or due to sudden accumulation of heat, causes a dangerous situation.

Furthermore, its volatility makes ethyl acetate easy to form a mixed gas of flammable steam and air in the air. Once this mixed gas reaches a specific concentration range, it will burn instantaneously in case of a fire source, and the transmission speed is extremely fast, which is very harmful. Therefore, in places involving ethyl acetate, it is necessary to strictly abide by safety procedures, prevent open flames, and strengthen ventilation to ensure safety, so that this chemical substance can play its due function under reasonable control, without causing disasters due to its flammability.
