Abstract: To provide a machine teaching terminal, a machine, a program, and a safety confirmation method capable of ensuring the safety of a worker without providing an additional device or the like. A machine teaching terminal communicably connected to a robot so as to be used for teaching the robot within a work area of the robot includes a touch panel display configured to accept input performed by a worker, an input detection part configured to detect input to the touch panel display, an abnormality detection part configured to detect an abnormal state on the basis of the detection by the input detection part, and an abnormal signal transmission part configured to transmit, in the case where the abnormality detection part detects the abnormal state, a signal indicating the abnormal state to the robot.
