A sacrificial barrier is a safety device that can be used to protect workers and others against hazards in an industrial setting.
These barriers are made of materials that can be easily damaged by physical contact with high-speed objects, hence, usually made in reasonable inexpensive materials.
Barriers
Pedestrian barriers are used for separation and protection. They can be used to separate pedestrians from vehicular traffic or to protect pedestrians from moving vehicles.
Pedestrian barriers are also used as safety devices in areas where there is a high risk of pedestrians being injured by vehicles.
