What is required when dropping materials from a height greater than 20 feet on construction sites?

When dropping materials from a height greater than 20 feet on construction sites, using enclosed chutes is required to ensure safety. Enclosed chutes control the direction of the falling material, preventing it from scattering and potentially causing injury to workers or damage to property below. Additionally, these chutes reduce the risks associated with falling objects, as they contain the load and direct it away from personnel areas.

Open chutes or platforms do not provide the same level of safety or control as enclosed chutes, and therefore do not meet the necessary safety standards for such operations. Utilizing enclosed chutes aligns with best practices and regulatory requirements aimed at minimizing hazards related to material handling at elevated heights.
