Avoid Dump-Point Hazards

Safety Something YOU can live with!
Mine Type: All Surface
Category: Haulage

In the 1990s, 25 miners died when their trucks went over the edge of a dump point. Many of these accidents occurred at truck-built stockpiles. A common factor in many of these cases was that the truck was dumping above an area where the toe of the pile had been loaded-out. When a stockpile has been loaded out, the material can stand at a steep angle. But, in this condition, the berm may be undercut and the edge of the pile is more prone to giving away under the weight of the truck.

To prevent these accidents, mine operators need to ensure that their stockpiling procedures prevent truck drivers from attempting to dump near the edge of a pile where either the area below the dump point has been loaded-out and over-steepened, or the berm is inadequate, or cracks are present.

Remember, routinely dumping short and pushing over, or routinely blocking the stockpile access ramp, are two ways to help prevent truck drivers from being exposed to potentially unsafe dump-point conditions. Avoid that dump-point hazard - "dump short", or "block the ramp."

Please Note: MSHA has published a Dump-Point Handbook. PH01-I-6 - Dump Point Safety.
