What is the unconfined compressive strength range for Type B soils according to OSHA?

The unconfined compressive strength range for Type B soils, as defined by OSHA, is specifically identified as between 0.5 tsf and 1.5 tsf. This classification is important in construction and excavation safety as it helps determine the level of stability and the necessary precautions that should be taken when working with these types of soils.

Type B soils are characterized by having moderate strength, a compressible nature, or the potential for some cohesion, which can implicate different safety considerations compared to more stable soil types. By correctly identifying this strength range, safety professionals can develop appropriate engineering controls and work practices to ensure that excavations and construction activities are conducted safely.

Understanding these classifications is vital for ensuring compliance with OSHA regulations regarding excavation safety and preventing soil-related accidents on construction sites.
