9 Hazards Pre-Identified & Risk-Assessed
Each hazard includes full control measures following the hierarchy of controls, with initial and residual risk ratings pre-calculated.
Fractures, head injuries, spinal injuries, death
Build deck at ground level where design permits
Use scaffolding with guardrails instead of ladders for elevated work
Install temporary edge protection/guardrails before commencing work on elevated decks
- Install permanent balustrades progressively as work advances
- Use work platforms with guardrails for elevated sections
- Ensure all ladders are industrial-rated (120kg minimum) and secured
- Cover all floor openings or incomplete sections
- Complete working at heights training for elevated deck work
- Never work on incomplete framing - install all joists before walking on deck
- Maintain three-point contact on ladders at all times
- Do not work on deck during wet or icy conditions
- Pre-plan access and egress routes before starting work
Fall arrest harness when edge protection not feasible, safety boots with good grip

Frequently Asked Questions
Common questions about this Timber Deck Construction SWMS template.
Do I need a SWMS for building a timber deck?
Yes, if the deck construction involves excavation near underground services or working at heights exceeding 2m, it is classified as high-risk construction work under WHS Regulation 2017. A SWMS must be prepared before work commences.
At what height do balustrades become mandatory on a deck?
Under the National Construction Code (NCC), balustrades are required on decks where the fall height exceeds 1 metre above the floor level below. The minimum handrail height is 1000mm for decks up to 4m above ground.
What H-class treatment is required for deck timber?
For above-ground external applications (decking, bearers, joists), H3 treatment is the minimum requirement. For ground contact or in-ground use (posts, bearers near ground), H4 treatment is required. Always check treatment stamps on timber.
Is BYDA (Dial Before You Dig) required for deck post holes?
Yes. Before You Dig Australia enquiry is mandatory before any excavation in all states. Even shallow post holes (450-600mm) can strike underground services. Failure to check can result in prosecution if services are struck.
Can I burn treated timber offcuts?
No. Treated timber (CCA, ACQ, LOSP) must never be burned. Burning releases toxic chemicals including arsenic and copper compounds. Offcuts must be disposed of at an appropriate waste facility that accepts treated timber.
What PPE is required for cutting treated timber?
A P2 dust mask is mandatory when cutting treated timber to prevent inhalation of preservative-laden sawdust. Safety glasses, work gloves, and long sleeves should also be worn. Hands must be washed before eating or drinking.
What is the maximum span for deck joists?
Joist spans depend on timber species, section size, and joist spacing. For 90x45mm treated pine at 450mm centres, typical span is approximately 1.5m. For hardwood, spans can be greater. Always refer to AS 1684 span tables or engineering specifications.
What qualifications do I need to build a deck?
No specific licence is required for residential deck construction in most states. However, a White Card (Construction Induction Card) is required on construction sites. Carpentry trade qualification or equivalent experience is recommended. Working at heights training is required for elevated decks over 2m.
