Flammable Materials and Source Control
Storage, use and transport of flammables; separation and control of ignition, fuel and oxygen sources.
How to prepare for both units
Learn the principle, locate scenario or workplace evidence, explain why it matters, recommend proportionate control and show how action will be owned and reviewed.
Core concepts
Concept 1
safe receipt, storage, use and transport of flammables
Exam cue: Prefer removing or reducing dangerous material before relying on procedural control.
Concept 2
minimising quantities and separating incompatible hazards
Exam cue: Check the full movement from delivery through use to waste, including spills and abnormal releases.
Concept 3
control of smoking, sparks, hot surfaces and oxygen enrichment
Concept 4
ventilation, containment and safe disposal
Risk pitfalls and guardrails
Keeping unnecessary working quantities at the point of use.
Guardrail: Do not answer with unsupported lists, invent a single UK legal regime, confuse the 24-hour FSC1 window with working time, treat the FSC2 three-hour recommendation as a limit or present internal allocations as NEBOSH weights.
Assuming ventilation always improves safety without checking where vapour is discharged.

Memory anchors
Minimise at the workplace
Keep only the necessary quantity at the point of use and store the remainder appropriately.
Separate fuel from ignition
Distance, barriers and controlled storage reduce the chance of contact.
Contain the release
Closed transfer, spill control and suitable containers limit vapour and fuel spread.
Oxygen can be enriched
Oxidisers and oxygen systems can make materials ignite more readily and burn fiercely.
Waste remains fuel
Contaminated rags, residues and discarded containers need controlled storage and disposal.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
