An access hatch comprises a frame, a grate, and a pull member pivotally coupled to the grate. The frame contains an access opening. The grate has a near side and a far side. The near side is coupled to the frame for pivotal movement of the grate between a closed and an open position. In the closed position, the grate lies substantially in the access opening of the frame and blocks at least a portion of the opening. In the open position, the grate is oriented away from the opening of the frame to allow access through the opening. 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 extends substantially to the near side of the grate when the proximal end is in the 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.
