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 Risk Assessment — Common Questions
What is the difference between a risk assessment and a SWMS?
A risk assessment provides a broad overview of all hazards for a scope of work at a site. A SWMS is task-specific and legally required for high-risk construction work. Both are important but serve different purposes.
Do I need a risk assessment if I have a SWMS?
Yes. A SWMS covers specific high-risk tasks. A site-specific risk assessment covers all hazards at the site, including those not classified as high-risk construction work.
What risk matrix do your assessments use?
Our risk assessments use a 5×5 likelihood-consequence matrix, providing initial risk ratings before controls and residual ratings after controls are applied.
