Summary:An access hatch having a frame containing an access opening, a grate, and a pull member pivotally coupled to the grate. The pull member has a proximal end and a distal end. The distal end is pivotally coupled to the grate near the far side of the grate, such that the proximal end is moveable away from the grate from a rest position. The proximal end is normally in the rest position when the grate is in the closed position. A worker, intending to open the grate, is prompted to stand at the near side of the grate and grasp the proximal end of the pull member, to pull the grate to the open position.
