The minimum height at which a safety net system must be installed to effectively catch falling objects is 15 feet. This standard is based on safety regulations that aim to mitigate the risk of injuries caused by objects falling from heights in construction and other work sites.

At heights starting from this level, the probability of objects falling becomes significant, and the implementation of safety nets serves as an essential precaution. By placing the nets at this height, it ensures that they can adequately capture materials or tools that may fall and thus provide a necessary protective barrier for workers and pedestrians below. This regulation underlines the importance of proactive safety measures in environments where overhead work is being conducted.

Installing safety nets lower than this height would not adequately address the risks associated with falling objects, while higher installation points are often not practical or necessary for effective protection.
