If debris is dropped more than how far to any point outside the exterior walls of a building, an enclosed chute must be used?

The requirement for using an enclosed chute when debris is dropped from a building pertains to safety regulations aimed at preventing injury to individuals and damage to property. According to the guidelines, if debris is dropped from a height that exceeds 20 feet to any point outside the exterior walls of a building, the use of an enclosed chute becomes mandatory. This regulation is in place to contain falling materials, reducing the risk of accidents and providing a safer work environment for both construction workers and the public.

Choosing a height of 20 feet aligns with industry best practices, ensuring that greater precautions are taken when debris is being transported vertically, particularly in urban environments where bystanders might be present. Lower heights, such as 10, 15, or 25 feet, do not reflect the regulatory threshold established to ensure adequate safety measures are in place for construction activities. This standard helps to manage the risks associated with the removal and disposal of construction debris effectively.
