What is the function of a warning line system?

The function of a warning line system is primarily to alert employees that they are approaching an unprotected side or edge where there is a risk of falling. This system is designed to enhance awareness among workers, helping them to recognize potential hazards as they navigate through areas where they might be working at height. By signaling the proximity of an unprotected edge, the system encourages workers to exercise caution and take necessary precautions, thereby reducing the likelihood of accidents or falls.

While physical barriers and instructions on safety procedures are critical components of an overall safety strategy, the warning line itself specifically serves the purpose of providing a visual indicator of danger. It acts as a threshold that indicates to workers that they should remain vigilant and mindful of their environment, especially in construction sites where edges may be unprotected. The primary goal of such systems is to prevent accidents and promote a safety culture on construction sites.
