What is the maximum vertical distance safety nets should be placed from the work surface?

Safety nets are critical fall protection measures used in construction to catch workers who fall from heights and prevent serious injuries. According to OSHA standards, safety nets should be installed at a maximum vertical distance of 30 feet below the work surface. This distance is based on research and industry standards that ensure the nets can effectively absorb the energy of a falling worker without allowing them to hit the ground or any hazardous conditions.

The choice of 30 feet takes into account various factors such as the net's design, material properties, and the potential for additional falling debris, ensuring that workers are adequately protected within the limits specified by safety regulations. Thus, the correct answer highlights best practices in maintaining a safe working environment on construction sites.
