Electrical Hazards and Risks
Electric shock, burns, arcing, fire, explosion, secondary falls, damaged systems and factors affecting injury severity.
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
Electric shock, burns, arcing, fire, explosion, secondary falls, damaged systems and factors affecting injury severity.
Exam cue: Name the specific construction evidence before applying the principle or control.
Concept 2
Identify voltage, current path, environment, duration and likely contact before choosing controls.
Exam cue: Prefer prevention and collective protection before procedural or personal controls.
Concept 3
Low voltage can still be dangerous in wet, confined or conductive conditions and can cause secondary injury.
Risk pitfalls and guardrails
Giving a generic hazard or control list without connecting it to people, task and site conditions.
Guardrail: Do not give a generic control list without linking it to the task, people, site conditions and verification method.
Treating a document, inspection or item of PPE as proof that the underlying risk is controlled.
Guardrail: Do not give a generic control list without linking it to the task, people, site conditions and verification method.
