Evacuation Strategies and the Public
Simultaneous, staged, phased and horizontal evacuation, alarm interaction and management of public occupants.
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
simultaneous, staged, phased and horizontal evacuation
Exam cue: Select the strategy from building design, protection, occupancy and management capability.
Concept 2
interaction between alarm sequence and evacuation strategy
Exam cue: Test how alarm messages, staff action and assistance support the chosen sequence.
Concept 3
members of the public and unfamiliar occupants
Concept 4
assembly, roll call, re-entry and contingency
Risk pitfalls and guardrails
Using phased evacuation without the systems and management required.
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.
Treating a roll call as reliable when visitor and contractor records are incomplete.

Memory anchors
Strategy follows the building
Compartmentation, detection, occupancy and staff capability shape evacuation.
Alarm and action must align
A staged or phased plan needs warnings that tell each group what to do.
Public need leadership
Visitors may not know routes or alarms, making trained staff and clear information essential.
Accountability needs good inputs
Staff, visitor and contractor information must be current enough to support roll call.
Re-entry needs authority
No one should return merely because the alarm stops.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
