The present invention relates to the field of engineering machinery, and discloses a method and an apparatus for judging the safety of an operation which may be performed by a boom and an engineering machinery, the method including: acquiring parameters for each arm in the boom, wherein the parameters comprise an inclination angle, an arm length, and mass; determining, based on the acquired parameters, a position of the full center of mass of the boom and a position of the combined center of mass from an operating arm to a terminal arm; determining a safety judging basis direction vector based on the position of the full center of mass and the position of the combined center of mass; and judging the safety of an operation which may be performed on the operating arm based on the safety judging basis direction vector. Therefore, it is realized to judge the safety of the operation which may be performed on the operating arm, and the operating arm has not been operated at the time of judging the safety, so the judgment of the safety of the operation which may be performed on the operating arm is pre-judgment, that is, the safety of the operation which is about to be performed on the operating arm is pre-judged, and the predictability is realized.
