A safety gate is provided with one or more of a curved path for holding a pressure mount to prevent unlocking, and a color-coded locked/unlocked status indicator for use in openings, such as doorways, to provide a barrier for a small child or for any other suitable use. The changing of the colors, from, for example, red to green indicates to a user that the gate is locked (green) or unlocked (red). The door opening mechanisms may allow the door to be unlocked or locked with one hand.
