What must be done if signs of soil instability are detected during excavation?

When signs of soil instability are detected during excavation, the immediate and correct response is to cease work and assess the risk. This approach prioritizes safety for all personnel on the job site. Soil instability poses significant hazards, such as collapses that can lead to serious injuries or fatalities. By stopping work right away, crews can evaluate the situation without exposing workers to additional danger.

This assessment typically involves a thorough inspection to identify the cause of instability, which may include factors like water accumulation, soil saturation, or changes in weather conditions. Once a risk assessment is conducted, appropriate measures can be taken to stabilize the area before work can safely resume. This proactive method ensures that safety protocols are followed and helps prevent potentially catastrophic incidents, making it a critical step in excavation safety practices.
