What type of soil is classified as granular soil by OSHA?

Granular soil, as defined by OSHA, refers to soils that have a coarse grain structure, typically characterized by sand and gravel. These types of soils have high permeability and are considered stable when dry. Granular soils are classified in Group C according to OSHA's soil classifications, which covers types of soils that are compacted but will not exhibit cohesion. This classification is essential for construction projects as it informs safety measures and excavation practices.

In contrast, other soil types such as cohesive soils (like clay) or those with different properties are classified differently by OSHA. Understanding these classifications is crucial for contractors to ensure safe excavation practices, manage the risks of soil collapse, and adhere to safety regulations. Thus, identifying granular soil as Group C helps in planning and executing construction activities safely.
