What is the required distance for erecting control lines from the unprotected edge?

The required distance for erecting control lines from the unprotected edge is specified to be not less than 6 feet nor more than 25 feet. This specification is crucial in fall protection measures for construction sites, ensuring that workers have a clear visual and physical boundary that alerts them to potential fall hazards.

Control lines serve as a warning system that indicates where workers should not work without additional fall protection measures in place. By establishing these lines within the range of 6 to 25 feet, OSHA balances the need to protect workers from falls while still enabling them to comfortably perform their tasks near the edges of elevated surfaces. This range also allows flexibility in different work scenarios, accommodating various site conditions while maintaining safety standards.

Understanding the importance of this distance helps ensure that proper safety protocols are followed, reducing the risk of accidents related to falls on construction sites.
