Plumbing hazards and controls, ready to check
When the job includes a trench, Gate Ready adds the hazards (trench wall collapse, falling into the excavation, striking underground services, and plant or spoil near the edge) and controls like these. Each one shows its type.
- AdminUnderground services located (Before You Dig Australia) and marked before digging; potholed by hand near services
- EngineerWalls 1.5 m deep or more shored, benched or battered before anyone enters (or a geotechnical engineer’s written advice followed)
- IsolateExcavation edge barricaded; covers over openings when unattended
- AdminSpoil, materials and plant kept back from the edge
- AdminSafe access and egress (ladder or ramp) within reach of workers in the trench
- AdminExcavation inspected before each shift and after rain or any change
- AdminEmergency procedure for rescue and first aid if someone is engulfed, set up before work starts
A trench or shaft deeper than 1.5 m is on the model national list of high risk construction work, and some states set their own rules, so check your regulator. Sewage and infection risks, noise, sun and heat, and manual handling are suggested for sewer work. Pipe lagging and old pipes can contain asbestos, so the asbestos check comes first. Gate Ready suggests, you review.
