Chute Blockage Prevention

Important Safety Reminder
A chute blockage can rapidly cause the complete collapse of the chute system.

If the chute is clogged and more debris is introduced, the total weight of the chute will rapidly increase, which could cause the entire chute system to collapse without warning.

A falling chute can cause serious injury or death.

The chute must not be allowed to clog. The chute system is not designed to withstand the massive additional weight that even a small blockage represents. A blocked chute is an extremely hazardous situation. It is essential that the chute be monitored constantly during use to prevent any blockages.


Prevent a blockage from forming in your chute:

  1. Keep the chute as straight as possible. Do not bend, crimp, kink, or constrict the chute.
  2. Designate a site safety monitor. The monitor is responsible for ensuring that the chute does not block.
  3. Break up debris before throwing it into the chute.
  4. Be aware that lightweight, bulky materials such as insulation, foam, thin roofing membrane can clog a chute more easily.
  5. Ensure that all debris introduced into the chute is discharging into the dumpster.
  6. Use a chute diameter that is appropriate for the debris type and size. Superchute offers 6 standard diameters, as well as custom diameters.


Chute Blockages Often Start in the Dumpster

  • Ensure the chute has approx 2 to 5 ft of clearance above the dumpster rim, so that debris can be seen to fall clear of the chute.
  • Do not install tarpaulins over the trash container. Workers must be able to see debris exiting the chute at all times.
  • If the dumpster is covered, or the chute is positioned below the container rim, workers will not be able to detect a blockage, or notice a blockage forming in the container.
  • Ensure that the roll-off container is promptly switched out as soon as it is full.
  • Here is a picture of a correctly installed chute with a gap over the container. The Superchute Breakaway Cord is used to direct the chute discharge for an even fill. This light cord is designed to fail if the container is hauled away while the chute is still tied to it!

 In the Event of a Blockage

  1. Evacuate the area below the chute.
  2. Do not approach the chute, manipulate the chute, or attempt to clear the blockage.
  3. Consider that the chute system could fail at any moment without warning.
  4. Bring in a crane with lots of residual capacity to lower the chute to the ground.
  5. Dismantle and clear the blockage once the chute is safely on the ground.
  6. Inspect, repair, and reinstall the chute.
