Intent
Intent 1: 
To limit the probability that rooms or bins into which a refuse chute discharges will be too small, which could lead to the accumulation and backup of refuse in the chute, which could lead to:
  • the intake openings into the chute becoming blocked with refuse, which could lead to the closures on such openings not being closed, which could lead to a fire involving the shaft spreading from the shaft through the intake openings to other parts of the building, which could lead to harm to persons in other parts of the building, and
  • chutes not being used, which could lead to refuse being placed outside of the chute in the room or compartment, which could lead to the buildup of refuse to a point where the door to the room or compartment will not close properly, which could lead to a fire spreading through the shaft intake openings or originating in the room or compartment spreading to other parts of the building, which could lead to harm to persons in other parts of the building.
