Step 4: Visually determine if the projection extends beyond the face of the slide projection gauge. Pass: A projection that does not extend beyond the face of the gauge passes. Fail: A projection that extends beyond the face of the gauge is considered a hazardous protrusion and should be eliminated. NOTE: This test procedure is not applicable to the underside of a slide chute. For a slide chute with a circular cross section, the portion of the underside not subject to this projection recommendation is shown in Figure 18. The general recommendations for projections in §B.2.1 are applicable to the underside of the slide.
