(1) You must provide either of these safeguards at the tail end of a slat conveyor if the slats are above the centerline of the chain: (a) A guard over the hazardous tail end; or (b) Warning signs if guards are impractical because of material flowing over the tail sprocket. (2) You must provide either of these safeguards when there is a gap between the slats wide enough to permit access to cross members below the slats: (a) A continuous pan under the slats; or (b) Keep all cross members a safe distance from the slats.
