Electrical Safety
Supply selection, cables and connectors, inspection, isolation, wet conditions, overhead lines and electrical emergency response.
How to prepare for the CITB Operatives test
Connect hazard recognition with safe action: stop, protect, follow the site system and escalate to the right competent person.
Core concepts
Concept 1
Electrical systems and equipment must be suitable, protected, inspected and used within the site's distribution and isolation arrangements.
Exam cue: Inspect equipment, plugs, cables and connectors before use without dismantling them.
Concept 2
Damage, overheating, exposed conductors, water ingress or improvised connections require isolation and competent repair.
Exam cue: Use the assigned voltage, protection and connection rather than a makeshift adaptor.
Concept 3
A person or plant can be harmed without directly touching an overhead line because electricity may arc across a gap.
Exam cue: Keep clear after contact with an overhead line and follow the emergency plan.
Risk pitfalls and guardrails
Repairing a cable with ordinary tape and returning it to use.
Guardrail: Do not solve a missing guard, isolation, barrier, competent plan or engineering control only with a warning or PPE.
Assuming low voltage means no injury, fire or equipment risk.
Guardrail: Do not solve a missing guard, isolation, barrier, competent plan or engineering control only with a warning or PPE.
Approaching a machine in contact with a line before the supply is confirmed isolated.
Guardrail: Do not solve a missing guard, isolation, barrier, competent plan or engineering control only with a warning or PPE.
Memory anchors
Check, Connect, Protect
Inspect first, use the right supply and keep cables protected from damage.
Defect Means Isolate
Remove damaged electrical equipment from service and report it.
No DIY Repairs
Electrical repair belongs to an authorised competent person.
Dry Is Not the Only Test
Suitability also depends on voltage, environment, protection and equipment condition.
Lines Can Arc
Maintain the planned clearance; direct contact is not required for danger.
Contact? Stay Clear
Keep people away and follow the electrical emergency procedure.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
