Fuel, oxygen and ignition, combustion products, heat transfer, fire development and common construction fire conditions.
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
Fuel, oxygen and ignition, combustion products, heat transfer, fire development and common construction fire conditions.
Exam cue: Name the specific construction evidence before applying the principle or control.
Concept 2
Use the fire triangle and spread route to identify which source or pathway can be removed, separated or controlled.
Exam cue: Prefer prevention and collective protection before procedural or personal controls.
Concept 3
Consider smoke, toxic gases, visibility and oxygen depletion as well as flame and heat.
