Targeted study blocks
Knowledge
What this topic establishes
Understand the statutory focus on preventing danger, maintaining systems, controlling work near live conductors and ensuring people have appropriate competence.
Boundary
Where written knowledge stops
This overview is not legal advice and does not replace the current statutory text, HSE guidance or the employer's duty to assess the actual work.
Application
How to reason through a scenario
Identify the source of danger, the duty holder and the preventive action; reject answers based only on speed, habit or PPE.
Risk pitfalls and guardrails
treating the regulations as an equipment checklist only
Guardrail: Do not convert basic assessment knowledge into permission to perform a safety-critical practical task.
assuming a job title proves competence
Guardrail: Do not convert basic assessment knowledge into permission to perform a safety-critical practical task.
choosing live work to save time
Guardrail: Do not convert basic assessment knowledge into permission to perform a safety-critical practical task.
Memory anchors
Core aim of the Electricity at Work Regulations?
Electrical systems and work activities must be controlled so far as necessary to prevent danger.
Normal condition for work on conductors?
Made dead and kept dead unless the strict conditions for live work are all satisfied.
What does competence depend on?
Knowledge, training, experience and the nature of the work or adequate supervision—not a title alone.
Does compliance end at installation?
No. Construction, use, operation and maintenance must continue to prevent danger.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
