Plumbing work involves multiple high-risk construction activities under WHS Regulations s.291 including working in confined spaces (pits, tanks, trenches), excavation for drainage, gas fitting near ignition sources, and working at heights for roof plumbing.

Our plumbing SWMS pack is our largest with 23 documents covering hot water system installation, drainage and sewer work, gas fitting, confined space entry, excavation and trenching, roof plumbing, fire services, backflow prevention, and stormwater systems. Each document addresses trade-specific hazards including scalding from hot water, gas leaks and explosion risk, trench collapse, biological hazards in sewer work, and confined space atmospheric hazards.

Key Hazards Covered

Confined space atmospheric hazards (toxic/oxygen-deficient)
Trench collapse during excavation
Scalding from hot water systems
Gas leaks and explosion risk during gas fitting
Biological hazards in sewer and drainage work
Falls from height during roof plumbing
Underground service strikes

Plumbing SOP — Common Questions

What is the difference between a SOP and a SWMS?

A SOP provides step-by-step instructions for completing a task safely. A SWMS is a legal document specifically for high-risk construction work that focuses on hazard identification and risk control. SOPs are broader and apply to all tasks, not just HRCW.

Why do I need SOPs if I have SWMS?

SWMS only cover high-risk construction work. SOPs cover all tasks, including routine operations, equipment use, and procedures that don't qualify as HRCW but still need standardised safe practices.

Are your SOPs trade-specific?

Yes. Each SOP is written for specific trade activities, with relevant safety controls, PPE requirements, and references to applicable Australian Standards.
