Work-at-Height Systems and Rescue (WAH)
Selecting collective protection, restraint or arrest systems and maintaining inspection, anchor, exclusion and rescue controls.
How to prepare for a CITB Specialist test
Lock in common site safety first, confirm the exact route with the card scheme, then add the relevant specialist hazards and competence boundaries.
Core concepts
Concept 1
The hierarchy still requires avoiding height work and using collective prevention before personal restraint or fall arrest.
Exam cue: Distinguish work restraint, which prevents reaching a fall position, from fall arrest, which stops a fall after it starts.
Concept 2
Personal systems depend on compatible components, suitable anchors, clearance, inspection, training and correct connection.
Exam cue: Check the whole system and environment, including sharp edges, pendulum risk and objects below.
Concept 3
A prompt planned rescue is required because suspension after an arrested fall can remain dangerous.
Exam cue: Keep people outside falling-object and dropped-tool zones.
Risk pitfalls and guardrails
Selecting fall arrest first because a harness is available.
Guardrail: Do not mix specialist routes or replace an engineered, competent control with a briefing, warning sign or PPE alone.
Clipping to an unverified convenient structure.
Guardrail: Do not mix specialist routes or replace an engineered, competent control with a briefing, warning sign or PPE alone.
Relying on emergency services as the only rescue plan.
Guardrail: Do not mix specialist routes or replace an engineered, competent control with a briefing, warning sign or PPE alone.
Memory anchors
Avoid, Prevent, Arrest
Move down the hierarchy only when the higher control is not reasonably practicable.
Restraint Prevents Reach
A restraint system should stop the user reaching the fall edge.
Arrest Needs Clearance
Allow for system extension, user movement and obstructions below.
Anchor Must Be Suitable
Convenience does not prove strength, position or compatibility.
Inspect the Whole System
Harness, connectors, lanyard, anchor and records all matter.
Rescue Is Preplanned
Provide equipment and competent people before exposure begins.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
