Check if the machine will not start all of sudden before switching on the engine

Any accident foreseen here?

A battery in a dozer shovel (otherwise called a traxcavator) has run down. The operator tries to charge it by connecting it with that of a nearby hydraulic excavator with an electric cable. Another worker standing on the dozer shovel proceeds to starting the engine.

Now what accident do you anticipate from this picture?

This is the accident resulted!

The shift lever of the dozer shovel was in the REAR position. And what is worse, the parking brake had not been applied. Thus when the worker switched on the ignition key, the machine jerked backward. The operator was sandwiched between the two machines and killed.

Tips for forestalling similar accidents

1. An operator of dozer shovels will surely take all precautions for preventing the machines from runaway such as applying the parking brake, when he/she leaves the operator's seat.
2. Check if the machine will not start all of sudden before switching on the engine.
3. Do not allow anybody an access to a construction vehicle in operation and the neighborhood, if and when there is the danger that he/she may be hurt through coming into contact with it.
4. Should a battery of construction vehicle run down while in use under the normal conditions, it should be replaced with new one.
