Make out working procedures for machine inspection, maintenance, refueling

Any accident foreseen in this frame?

An operator worker is ready to start digging a U-shaped gutter at the construction site of a park, using a small size hydraulic excavator. It is in the morning, and there comes another worker this way with a polyethylene fuel container. He is supposed to fill the machine with fuel before the day's work.
Unable to start the engine, the operator is waiting for him impatiently in the operator's seat. By the way an overhead acryl plate for protection is missing at the operator's side of the machine, since it had been broken and removed for replacement.


Now what accident do you anticipate from this picture?



This is the accident resulted!

While he was watching him filling fuel, he inadvertently touched the bucket control lever, which let down the bucket. He was caught in between the falling boom and one of the cab guard pillars and killed.


Tips for forestalling similar accidents

1. Should any of the protective devices be removed from construction vehicle, reinstall it immediately and never use them until after it is in place.
2. Make out working procedures for machine inspection, maintenance, refueling, etc. for safety assurance, and see that they are observed without fail.
3. If it cannot be avoided to carry out works under a raised bucket, secure it with support pillars or blocks to ensure safety.
4. Implement education and training for safety in machine inspection, maintenance, refueling, etc.
5. Create an organization responsible for inspection and maintenance that includes voluntary inspection of the machines.
