What is a "safety barrier"?

A safety barrier is a physical structure used to protect people from potential hazards or dangerous areas.

They are often brightly colored or marked with warning signs to make them easily visible. Safety barriers help to keep workers and the public safe by clearly marking off hazardous areas.
