Work-at-height Planning, Roofs and Fragile Surfaces
Avoidance hierarchy, prevention, mitigation, roof planning, weather and fragile-material control.
How to prepare for an IOSH construction course
Use the developing site scenario to practise proportionate decisions, then confirm the exact assessment and delivery arrangements with your IOSH-approved provider.
Core concepts
Concept 1
Work at height should be avoided where reasonably practicable, then falls prevented, then consequences minimised.
Exam cue: Choose collective protection before personal fall protection where practicable.
Concept 2
Planning considers duration, frequency, access, loading, rescue, weather, edges, openings and people below.
Exam cue: Treat roof lights and unknown surfaces as potentially fragile until verified.
Concept 3
Fragile surfaces require identification, controlled access, suitable platforms or protection, warning and rescue arrangements.
Exam cue: Stop when wind, rain, ice or visibility invalidates the plan.
Risk pitfalls and guardrails
Selecting equipment before assessing whether height can be avoided.
Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.
Relying on warning notices without physical protection.
Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.
Starting roof work without a rescue method.
Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.
Memory anchors
Avoid, Prevent, Minimise
Follow the work-at-height control hierarchy.
Collective Before Personal
Protect everyone without relying first on individual action.
Fragile Until Proven
Unknown or roof-light surfaces need controlled protection.
Weather Can Withdraw Work
Conditions can cancel an otherwise sound plan.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
