Core concepts
Concept 1
Fire triangle, classes, ignition and fuel sources, heat transfer and common causes and consequences.
Exam cue: Identify the workplace evidence, people exposed, hazard mechanism and applicable duty before selecting a control.
Concept 2
Identify fuel, oxygen, ignition and spread route before choosing prevention and protection.
Exam cue: Prefer elimination and engineered or collective protection before procedural controls and PPE, then verify effectiveness.
Concept 3
Fire class and extinguishing medium must be matched; electrical involvement is not a standalone fuel class.
Risk pitfalls and guardrails
Giving a generic hazard or control list without connecting it to the task, people and workplace conditions.

Guardrail: Do not give a generic control list without linking it to the task, people, environment, owner and verification method.
