Keep away from shovel machine

Keep away from shovel machine

What kind of accident is about to happen?

The battery of a neglected hydraulic shovel has died, and a small dump truck driver is using battery cables to connect it to the battery of his truck.
The drag shovel operator is trying to start the engine.

Can you predict what's about to happen?

Look what happened!

The drag shovel operator started the engine and accidentally hit the rotate lever, rather than the lever to raise the boom. The shovel turned suddenly, crushing the driver of the small dump truck between his truck and the counterweight of the shovel.

Tips for preventing similar accidents

1. When starting an engine, confirm that safe conditions exist within the operating range.
2. Confirm differences in control patterns for different models of machinery.
3. Do not enter the operating range of a hydraulic shovel.

Take notice when drive on the road with rock fallen

Take notice when drive on the road with rock fallen

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.

Dangerous sittuation on the slope of mountain

Dangerous sittuation on the slope of mountain

Any accident foreseen in this frame?

This is a worksite for building a construction road. A hydraulic excavator is pulling hewn logs with a chain to remove them from the site.

Now what accident do you anticipate from this picture? 

This is the accident resulted!

The tugged logs were sent leaping and went down the slope on the valley side. Linked with a chain, the upper structure of the machine was then widely swung, then lost balance and rolled over. The operator was crushed under the fallen machine.

Tips for forestalling similar accidents

1. Use a special purpose machine for transport of logs such as skid loaders.
2. Operate a construction machine within its maximum capacity.
3. Fasten a wire rope securely to the logs.

Safety when using excavator crane concrete water pipe

Safety when using excavator crane concrete water pipe

Any accident foreseen in this frame?

At a construction site of burying city water pipes, a hydraulic excavator is traveling with a pipe weighing 53 kg that is hung with a wire rope fixed at the center. A worker is holding the pipe with his hand to prevent it from swaying.

Now what accident do you foresee occurring in this frame?

This is the accident resulted!

The operator suddenly changed the course to avoid a big stone ahead. Then the hung pipe made a big sway, pulling the worker down. He was run over by the excavator and killed.

Tips for forestalling similar accidents

1. Strictly follow the rules restricting the use of hydraulic excavators in unintended applications (see the Article 164 of Rules of Industrial Safety and Health Law).
2. Take every precaution for safety at the worksite beforehand. In this instance remove, remove big stones lying on the planned traveling course.
3. Train operators thoroughly not to jerk hydraulic excavators as well as their work equipment.

Compact the asphalt road safety notice

Compact the asphalt road safety notice

Any accident foreseen in this frame?

At a road construction worksite, a road roller has compacted the asphalt surface. Thereafter a worker is filling dents on the surface with asphalt using a rake nicknamed a "dragonfly".

Now what accident do you foresee occurring in this frame?

This is the accident resulted!

The operator backed up the road roller without thoroughly checking the rear. Standing in the dead angle area for the operator, the worker was pushed down from behind by the roller and crushed beneath it.

Tips for forestalling similar accidents

1. Do not allow workers to enter the working area of road rollers while in operation.
2. If it becomes definitely necessary to do so, post a work conductor at the site and let everyone follow his/her instructions.

Safety when demolish wooden house

Any accident foreseen in this frame?

Equipped with a fork grab, a hydraulic excavator is loading debris generated from the demolished wooden houses. In the truck body, two workers are spreading the wooden debris evenly.

Now what accident do you anticipate occurring in this frame? 

This is the accident resulted!

The hydraulic excavator suddenly swung to the right, grabbing the wooden debris, and hard hit one of the workers on the truck. He fell off the truck dead.

Tips for forestalling similar accidents

1. Do not allow anybody to come within the reach of the fork grab, while a hydraulic excavator is in operation.
2. Post a conductor at the worksite who controls the work.
3. Avoid a sudden and fast swing of hydraulic excavators.
