The safety sign is mounted on the building and moveable between an exterior warning position wherein a warning sign is displayed and visible exterior of the building, warning shooters that it is not safe to shoot, and an interior warning position wherein the warning sign is visible inside the building and provides warning to occupants that it is not safe to exit the building. Preferably, the safety sign is mounted near the exit door of the building and partially obstructs the exit when in the interior warning position so as to provide further warning to occupants not to exit the building.
