Pipelayers work in open trenches handling heavy pipe sections, making joints, and operating close to excavation plant. The combination of deep excavations, heavy manual handling, and proximity to machines makes this one of the highest-risk trades on a civils site. This talk covers the specific hazards pipelayers face and the controls that keep them safe during pipe installation operations.
Key Hazards
Trench collapse burying workers during pipe laying in unsupported excavations
Crushing injuries from pipes rolling or swinging during lowering into the trench
Back and shoulder injuries from manual handling of heavy pipe fittings
Struck by excavator bucket operating in close proximity to the trench
Control Measures
Ensure trench support is in place before entering the excavation to lay any pipe section.
Use mechanical lifting aids such as excavator-mounted pipe grabs for lowering pipe into the trench.
Maintain safe clearance from the excavator bucket swing radius when working in or near the trench.
Wear knee pads and use ergonomic pipe tools to reduce strain during jointing activities.
Check pipe bedding material is placed and levelled before positioning each pipe section.
Use tag lines to guide pipes being lowered by machine and never stand directly beneath a suspended pipe.
Inspect trench support daily and after any event that could affect ground stability.
Keep the trench base clear of standing water using pumping before laying pipe sections.
Brief the team on the day's pipe run, joint types, and any changes to ground conditions.
Remember
Trench support must be fully installed before anyone enters the excavation to lay pipe
Use mechanical lifting aids to lower pipe sections and never stand beneath a suspended pipe
Maintain safe clearance from the excavator bucket swing radius at all times in the trench
Inspect trench support systems daily and after rainfall or any event affecting ground stability
Use tag lines to guide pipe sections being lowered by machine into the trench
Brief the team each morning on the day's pipe run, joint types, and ground conditions
