Decontamination

S3 — Operations: Core

Why this chapter matters

Decontamination reduces cross-contamination; EMS stays at perimeter unless trained for mass-decon operations.

Learning objectives (6)

  1. Describe emergency decon — Rapid reduction of contamination on victims and responders at incident.
  2. Contrast technical decon — Deliberate process with monitoring for entry teams returning from hot zone.
  3. EMS perimeter role — Triage and treatment in cold zone; coordinate with decon corridor leaders.
  4. Identify ambulatory corridor — Walking patients processed separately from stretcher lanes.
  5. Awareness limitation — Do not operate decon corridor without operations training and PPE plan.
  6. Hospital coordination — Notify receiving facility of contamination status and route.

Quick fire sample (15 of 82 on Quiz Me)

Emergency decon is:
  1. Rapid reduction of contamination at incident
  2. Long-term landfill closure
  3. Only hospital billing
  4. Stretcher maintenance
EMS at mass decon typically:
  1. Operates at perimeter/triage, not inside hot zone
  2. Patches valves in Level D
  3. Runs finance section only
  4. Ignores command
Technical decon supports:
  1. Entry teams leaving hot zone
  2. Public cafeteria service
  3. Non-emergency training only
  4. Ignoring monitoring
Gross decon is:
  1. Initial removal of outer contamination
  2. Final site restoration only
  3. Only paperwork
  4. Hospital discharge
Awareness responders should not:
  1. Operate decon corridor without qualification
  2. Notify hospitals
  3. Establish perimeter info
  4. Request specialists
Runoff control prevents:
  1. Spread of contaminated wash water
  2. All radio communications
  3. ICS formation
  4. Patient transport
