Question: Which of the following is a critical safety consideration when benching a trench?
Answer options:
- Ensuring the bench width is at least twice the trench depth.
- Maintaining a consistent slope on all benches. ✅ Ensuring benches are wide enough to accommodate the excavator tracks safely.
- Applying a protective coating to the bench face to prevent erosion.
Correct answer: Ensuring benches are wide enough to accommodate the excavator tracks safely.
Explanation: When benching a trench, it is critical that the benches are wide enough to safely accommodate the excavator's tracks for stability and to prevent the machine from overturning or falling into the trench. While consistent slopes and erosion control can be important, the immediate safety of the equipment and operator regarding bench width is paramount. There is no universal rule that bench width must be twice the trench depth; it depends on soil conditions and design.
