Working at Height Hazards and Controls
Avoidance, prevention and mitigation of falls, fragile surfaces, openings, weather, falling materials and rescue needs.
How to prepare for CN1
Learn the principle, locate scenario evidence, explain why it matters, choose proportionate controls and show how actions will be prioritised and reviewed.
Core concepts
Concept 1
Avoidance, prevention and mitigation of falls, fragile surfaces, openings, weather, falling materials and rescue needs.
Exam cue: Name the specific construction evidence before applying the principle or control.
Concept 2
Apply the hierarchy: avoid height, prevent falls with collective protection, then minimise distance and consequence.
Exam cue: Prefer prevention and collective protection before procedural or personal controls.
Concept 3
Short duration does not make a poor access method suitable; consider task, load, environment, rescue and frequency.
Risk pitfalls and guardrails
