Risk-Based Inspection Programmes
Set and review maintenance activity from environment, users, construction, equipment type, use, history and service life.
Prepare from maintenance duty to traceable decision
Start with responsibility and risk, classify the equipment, inspect before testing, choose relevant measurements, interpret all evidence and complete an honest record.
Core concepts
Concept 1
Set and review maintenance activity from environment, users, construction, equipment type, use, history and service life.
Exam cue: Assess risk factors, choose user checks, visual inspection and testing proportionately, record outcomes, then adjust the interval using evidence.
Concept 2
The IET 5th edition removed a fixed frequency table in favour of a risk assessment informed by equipment and use.
Exam cue: Separate the evidence needed for the written decision from the live competence required to obtain it safely.
Concept 3
Previous records are evidence for review; they do not justify extending an interval when use or environment has changed.
Concept 4
A risk-based interval must remain defensible and subject to review after defects, incidents or material changes.
Targeted study blocks
Purpose
Identify the safety decision
Set and review maintenance activity from environment, users, construction, equipment type, use, history and service life.
Method
Use an evidence-led sequence
Assess risk factors, choose user checks, visual inspection and testing proportionately, record outcomes, then adjust the interval using evidence.
Boundary
Preserve practical and legal limits
A risk-based interval must remain defensible and subject to review after defects, incidents or material changes. Do not default to annual testing or assume every low-risk item needs an electrical test.
Risk pitfalls and guardrails
Do not default to annual testing or assume every low-risk item needs an electrical test.
Guardrail: Inspect first, use only relevant tests and keep the written decision within the practical and legal boundary.
Do not treat a fixed interval, one reading or a test label as the complete maintenance decision.
Guardrail: Inspect first, use only relevant tests and keep the written decision within the practical and legal boundary.

Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
