Cases Involving Construction Vehicles
| What kind of accident is about to happen? |
|
A bulldozer heading to collect lumber is traveling along a work road created by excavating the side of a mountain road, and piling it up along the ravine side of the road. Some rocks have fallen from the mountainside and are blocking part of the roadway, so the bulldozer operator is trying to avoid them. Can you predict what's about to happen? |
|
| Look what happened! |
|
When trying to go around the pile of rocks, the bulldozer ended up hitting the shoulder on the ravine side of the road. The shoulder, which was made of dirt, collapsed, and the bulldozer tumbled down the side. |
|
| Tips for preventing similar accidents | |
| 1. | Machinery operators should recognize that shoulders are unstable. If a shoulder is at risk of collapsing, halt work and take necessary safety measures. |
| 2. | Inspect work roads before starting work. To ensure safe travel, remove obstacles in the road and reinforce weak shoulders. |
| 3. | When there is a risk of a bulldozer tumbling down a shoulder or incline, take safety measures, such as assigning someone to serve as a guide, or installing guardrails or signs. |
