Occupational Safety, Health, and Environmental Management
What the domain tests
Occupational Safety, Health, and Environmental Management tests hazard control at road works and the environmental duties of public projects.
Core rules and concepts
- Hierarchy of controls: eliminate, substitute, engineer, administrate, then use PPE. PPE is the last line.
- Risk assessment identifies hazards, likelihood, severity, and controls; toolbox talks communicate them.
- Traffic management at work sites uses signs, cones, barriers, flaggers, safe diversion, and reflective clothing.
- Excavations need shoring or safe battering, barricades, access control, and utility checks.
- Working at height and machinery require trained operators, guards, inspection, and exclusion zones.
- Environmental controls include dust suppression, noise limits, erosion and sediment control, spill kits, and waste disposal.
Worked example. A deep trench is opened beside a live carriageway. Controls include a written traffic plan, reflective signs and barricades, shoring or safe battering, a flagger, and no unsupervised entry. Reasoning: separate traffic from workers and prevent collapse.
Traps that cost marks
Relying on PPE alone; ignoring near misses; leaving excavations open at night; allowing untrained flaggers; and poor spoil or fuel storage.
