The invention discloses a fireproof safety door. A water spray mechanism is arranged in a door frame, the water spray mechanism comprises water pipes arranged in the orientation of the door frame, thewater pipes communicate with the outside water source through a three-way joint, and a temperature-sensitive device is arranged between the three-way joint and the outside water source; a plurality of latticed empty cavities are formed in a door body, the empty cavities are filled with flame retardants and water bags, wherein the flame retardants and the water bags are separated from each other,the flame retardants comprise spongy layers and rock wool layers arranged on the two sides of the rock wool layers, and the water bags are connected with the inner walls of cavities bodies of the empty cavities of the door body through supporting plates. The water spray mechanism, the flame retardants and the water bags are arranged, when fire happens, on the one hand, water sprayed from the waterspray mechanism forms a water curtain to block flames, and the water curtain further has certain absorption action on smoke dust in air; and on the other hand, the flame retardants can greatly improve the heat-insulating performance of the door body, when the water bags shrink and crack after heated, internal loaded tap water overflows from a through hole of the door body, and the temperature rise speed of the fireproof safety door is effectively reduced.
