GR-05 / SPACE IS A SAFETY CONTROL
Live traffic interfaces
Separate plant, deliveries and public movements before selecting the largest machine that fits the task.
Rule of thumb
Space is a safety control. Separate plant, deliveries and public movements before selecting the largest machine that fits the task.
01
Plan traffic
A traffic guidance scheme sets controls and equipment.
02
Create separation
Barriers and exclusion zones keep people clear of plant.
03
Use spotters
Spotters and radios manage reversing and deliveries.
04
Choose compact plant
Smaller machines reduce road occupancy.
BY STATE
Where it matters
Regional conditions that make this rule especially relevant.
NSWNew South WalesSydney sits largely on Hawkesbury sandstone and Wianamatta shale with reactive clays to the west; inland plains carry black-soil clays that become impassable after rain.→VICVictoriaMelbourne's west and north sit on basalt with highly reactive clays; the south-east has sand. Basalt floaters routinely slow excavation and trenching in the growth corridors.→QLDQueenslandBlack-soil and reactive clays are widespread inland; coastal areas include acid sulfate soils and high groundwater that affect excavation and dewatering.→WAWestern AustraliaPerth sits on the Swan Coastal Plain's deep sands—easy digging but unstable trench walls and demanding compaction. Inland and in the Pilbara, hard rock and caprock call for breakers and ripping.→SASouth AustraliaAdelaide's plains carry highly reactive clays; the Limestone Coast has shallow limestone; the north is arid with gibber and calcrete.→TASTasmaniaDolerite dominates much of the south and midlands, making rock excavation common; steep terrain and wet winters shape access.→NTNorthern TerritoryLaterite and gravels in the Top End become boggy in the wet; the Centre has sand, rock and calcrete.→ACTAustralian Capital TerritoryVariable clays, weathered rock and volcanic formations; rock is common on hillside suburbs.→
