What is a grain bridge?

A grain bridge refers to a solid layer of grain that can form over an empty space, such as a build-up of grain that is not adequately supported beneath. This situation arises when grain is stored in silos or other containers, and as the grain is drawn down, an unsupported layer may create a bridging effect. If weight is added, such as a person walking across the bridged grain, this can lead to a dangerous collapse, posing a significant risk of injury or entrapment.

Understanding the concept of a grain bridge is crucial for safety as it highlights the potential hazards of working with stored grain. Proper training and awareness can help prevent accidents related to grain bridging, emphasizing the need for safe operating procedures when handling grain. Recognizing the signs and conditions that lead to grain bridges can be vital for ensuring a safe environment when working in areas where grain is stored.
