What safety measures must be implemented when inspecting under a raised attachment?

When inspecting under a raised attachment, implementing chocks, blocks, or safety bars is crucial for ensuring the safety of the operator and anyone in the vicinity. These devices provide essential stability and support for the raised component, preventing accidental lowering or movement that could pose serious risk during the inspection process.

Using chocks or blocks effectively stabilizes the machinery, ensuring that it stays in the raised position and does not shift unexpectedly. Safety bars further enhance this stability by offering an additional level of security, which helps to mitigate potential hazards associated with working underneath heavy equipment. This practice is vital for maintaining a safe working environment and protecting workers from injury.

While using a safety helmet, wearing reflective clothing, and utilizing mirrors for visibility are important safety practices in construction and excavation work, they do not specifically address the dangers associated with inspecting under a raised attachment. The primary concern in this scenario is the risk of unintended movement of the equipment, which makes the use of chocks, blocks, or safety bars the correct measure in this context.
