The maximum opening size allowed in safety net systems is 36 square inches. This specific size is established to ensure that a person falling into the net is adequately restrained and cannot pass through the opening, minimizing the risk of injury. Safety nets are designed to catch personnel and debris during construction or maintenance work at heights, and controlling the size of openings is crucial to maintaining the effectiveness of these safety systems. By limiting the opening size to 36 square inches, regulations help enhance safety standards and protect workers, ensuring that the nets function as intended in preventing falls and related accidents.
