Question

check the different types of protective systems

shield
shoring
sloping
bending
benching
sliding
branching

Explanation:

Identify the context of protective systems

Using the Occupational Safety knowledge point, we recognize that protective systems designed to prevent cave-ins during excavations and trenching are regulated by safety standards such as OSHA.

Evaluate each option against safety standards

We analyze the standard types of trench protective systems:

• Shielding (Shield): Uses trench boxes or other supports to protect workers inside a trench. This is a valid protective system.
• Shoring: A structure such as metal hydraulic, pneumatic, or timber shoring that supports the sides of an excavation to prevent cave-ins. This is a valid protective system.
• Sloping: Cutting back the trench wall at an angle inclined away from the excavation. This is a valid protective system.
• Bending: Not a recognized trench protective system.
• Benching: A method of protecting employees from cave-ins by excavating the sides of an excavation to form one or a series of horizontal steps or benches. This is a valid protective system.
• Sliding: Not a recognized trench protective system.
• Branching: Not a recognized trench protective system.
