Dropping Construction Debris

It's important that drop chutes are designed and constructed of strong enough materials to eliminate failure due to impact of materials and debris.

Make sure drop chutes are strong enough for materials.

When drop chutes are in operation, make sure a competent person is always assigned to control the operation of the chute gate, and the backing and loading of trucks.

  • Never allow material to be dropped to any point lying outside the exterior walls of the structure unless it is effectively protected.
  • Plank off solid floor openings within 10 feet of any wall being demolished, except when employees are kept out of the area below.
  • Make sure that the waste and debris stored on any floor does not exceed the allowable floor load.
  • Enclose material chutes at greater than a 45-degree angle from the horizontal unless openings are equipped with closures at or about floor level for the insertion of materials.
