Construction Supervisor License Practice Exam

A stairway, ladder, or ramp is required in trench excavations that are 4 or more feet in depth. What is the maximum distance apart they may be, in feet?

1. 10

2. 25

3. 35

4. 50

The correct answer is: 50

In the context of trench excavation safety, the requirement for stairways, ladders, or ramps is set to ensure safe access and egress for workers. When trenches are 4 feet or deeper, it is essential to have these means of access available to prevent accidents and injuries related to falls or inability to escape in emergencies. The maximum distance that these access points may be apart is determined by safety regulations aiming to protect workers from potential hazards. The correct spacing of 50 feet means that no worker should have to travel more than this distance to reach a safe means of access, ensuring quick egress if needed. By requiring that access be relatively close at hand, the regulations help mitigate risks associated with being in deep trenches, where conditions can change rapidly, and safe exit routes become critical. This regulation aligns well with safety practices in construction, where the wellbeing of workers is prioritized, and appropriate measures are taken to minimize risks effectively.
