VC-SOP-0404 — Facility Lockdown & Evacuation Routing
The governing procedure for sealing the Sector-7 Arboretum Complex by tier and routing personnel to muster during a containment or safety emergency — defining zone isolation, route selection by affected zone, muster accountability, and the conditions for stand-down.
⚠ LIFE-SAFETY PROCEDURE. A declared lockdown supersedes all other activity. Route away from the breach vector, never through a sealed bulkhead. Bulkheads that have sealed under CHLORA auto-response do not reopen for evacuation — use the assigned alternate route. Lockdown is most often triggered by a Tier-3+ breach under VC-SOP-0401; that procedure owns the breach, this one owns the building.
1. Purpose
To define the controlled procedure for placing the facility into a graded lockdown and routing all personnel to safe muster within target times — arresting dispersal at zone boundaries while preserving every life-safety egress that does not cross the hazard. The objective is full personnel accountability within 6 minutes of a Tier-3 declaration and zone isolation integrity at 100%.
2. Scope
Applies to all facility personnel, visitors, contractors, and to CHLORA. Governs lockdown of the four facility zones (A–D), the eight muster points, and all bulkhead, HVAC, and egress controls. The breach that triggers lockdown is governed by VC-SOP-0401; reversion of any CHLORA-initiated seal by VC-SOP-0409; exposure triage by VC-SOP-0307. Excludes routine drills, which run under VC-SOP-0411.
3. Definitions
| Term | Definition |
|---|---|
| Lockdown | Coordinated sealing of zone bulkheads and isolation of HVAC to arrest dispersal across a containment boundary. |
| Lockdown Tier | The graded scope of isolation — local, wing, or facility-wide — keyed to the declared breach tier of VC-SOP-0401. |
| Evacuation Zone | One of four physical partitions (A–D), each with a primary and secondary muster. |
| Muster Point | A designated accountability location outside the hazard envelope where personnel are counted. |
| Shelter-in-Place (SIP) | Holding within a sealed but uncompromised zone when egress would cross the hazard. |
| Stand-Down | The incident commander's signed release of lockdown after integrity verification and full accountability. |
4. Responsibilities
| Role | On Lockdown |
|---|---|
| Director of Ops (Owner) | Declares lockdown tier; assumes incident command at LD-3; authorizes stand-down; owns this SOP. |
| Watch Commander | Holds incident command at LD-1/LD-2; confirms zone isolation; directs route selection. |
| Safety Officer | Runs muster accountability; reports all-mustered or names missing within target time; triages exposure (VC-SOP-0307). |
| Zone Wardens (A–D) | Sweep their zone, drive personnel to the assigned muster, confirm zone clear by hand-count. |
| Egress Control Tech | Verifies alternate-route lighting and door states; clears mechanical obstructions. |
| CHLORA | Executes bulkhead/HVAC sealing; illuminates the live route by zone on the PhytoSense Mesh way-guides; maintains the lockdown log; cannot release a seal below LD-1 without dual human auth (VC-SOP-0409). |
5. Equipment & Pre-Checks
- Bulkhead and HVAC isolation actuators self-tested green (CHLORA pre-shift poll, ≤ 8 h old)
- PhytoSense Mesh way-guide strips powered and addressable in all four zones
- Muster-point beacons (8) and accountability scanners online
- Egress PPE caches stocked at each zone vestibule (minimum Level-C respirators)
- Alternate-route maps current and posted at every bulkhead intersection
- MDF backup comms channel reachable independent of primary alarm bus
6. Lockdown Tiers & Evacuation Routing
Lockdown tier maps to the declared breach tier of VC-SOP-0401. The affected zone evacuates outward-away from the breach to its assigned muster; adjacent zones shelter-in-place until cleared.
| LD Tier | Scope of Seal | Affected Zone Action | Muster / Route | Target Accountability |
|---|---|---|---|---|
| LD-1 | Single bulkhead, zone-local | Local egress to nearest muster; work elsewhere continues | Zone primary muster, marked green way-guide | 8 min |
| LD-2 | Wing-level; HVAC isolated | Affected wing evacuates; adjacent wings SIP | Zone primary; secondary if primary in hazard arc | 6 min |
| LD-3 | Multi-zone; cross-bulkheads sealed | Affected zones evacuate to facility perimeter musters | Secondary musters via perimeter ring corridor | 6 min |
| LD-4 | Facility-wide; full bulkhead lattice | Total evacuation to external assembly; SIP only if egress crosses hazard | External Assembly North / South per zone | 4 min + perimeter count |

7. Procedure
7.1 Declare & Set Tier
- On a breach declaration under VC-SOP-0401, CHLORA maps the breach tier to a lockdown tier and stages the seal pattern within 3 s.
- The incident commander (Watch Commander at LD-1/2, Director of Ops at LD-3/4) confirms or upgrades the lockdown tier within 30 s.
- CHLORA broadcasts the tier, the affected zones, and the active route set on every alarm and way-guide channel.
7.2 Isolate & Seal
- CHLORA seals the bulkhead lattice for the declared scope and isolates HVAC dampers to prevent cross-zone dispersal.
- Way-guide strips in the affected zone switch to the egress route; routes crossing the hazard arc are extinguished and locked out.
- Any seal blocking a primary muster automatically promotes that zone to its secondary route — the way-guide reflects the change before personnel reach the intersection.
7.3 Route & Evacuate
- Personnel follow the lit way-guide to the indicated muster; do not attempt a sealed bulkhead or an extinguished route.
- Zone Wardens sweep their zone end-to-end, driving stragglers ahead of them, and confirm the zone clear by hand-count at the muster.
- Where egress would cross the hazard, occupants shelter-in-place in the nearest sealed-but-clean space and report their headcount on the MDF backup channel.
7.4 Muster & Account
- Safety Officer aggregates muster-scanner counts and Warden hand-counts against the on-shift roster.
- Report all-mustered or names/locations of the unaccounted to the incident commander within the tier target time (Section 6).
- Any unaccounted person triggers a directed search by the Containment Team only on a route CHLORA confirms is held; no solo entry.
7.5 Stand-Down
- Lockdown is released only after the breach is re-contained (VC-SOP-0401 §7.4), zone integrity is verified to 100%, and accountability is complete.
- CHLORA-held seals are released under dual human authorization per VC-SOP-0409; reversion to automated control follows the same SOP.
- The incident commander signs the stand-down; CHLORA timestamps the release and closes the lockdown log.
7.6 Quality Checkpoints
- Lockdown tier confirmed or upgraded within 30 s of declaration
- Bulkhead lattice sealed to declared scope with zero damper faults
- No active way-guide route crosses the hazard arc
- Accountability reported within the tier target time
- Every CHLORA-held seal released only under dual human auth at stand-down
- Zone integrity verified to 100% before release
8. Records
- CHLORA lockdown log — declaration, seal pattern, route changes, release (retained 10 years)
- Muster accountability record with timestamps per zone
- Warden zone-clear hand-count sheets
- Shelter-in-place headcount reports (MDF backup channel)
- Stand-down authorization with integrity-verification reference
