Removing Debris and Cleanup
Debris collection and removal tasks include picking up, clearing, separating, and removing debris.
Make sure the area is clear of cleanup workers before continuing demolition.
Most of these tasks are typically performed using heavy equipment; however, some manual effort can be necessary at every stage.
The foreman should determine when debris is to be removed, halt all demolition during debris removal, and make sure the area is clear of cleanup workers before continuing demolition.
- Make sure openings cut in a floor for the disposal of materials are no larger than 25 percent of the aggregate of the total floor area, unless the lateral supports of the removed flooring remain in place.
- Shore up floors weakened or otherwise made unsafe to safely carry the intended imposed load from demolition operations.
- If debris is dropped inside the shaft, it can be removed through an opening in the chimney at grade level.
- Keep the opening at grade level relatively small in order not to weaken the structure. Consult with a professional engineer if a larger opening is desired.
- When removing debris by hand, use an overhead canopy of adequate strength. If machines are used for removal of debris, use proper overhead protection for the operator.
- Do not allow excessive debris to accumulate inside or outside the shaft of the chimney as the excess weight of the debris can impose pressure on the wall of the structure and might cause the shaft to collapse.
