Three Safety Zones
  • Hot zone
  • Exclusion zone
  • Greatest amount of danger
  • Warm zone
  • Contamination reduction zone
  • Immediately outside hot zone
  • Cold zone
  • Support zone
  • Removal of all contaminated PPE and equipment
    before entering

7
Contamination Exposure Routes
  • Topical (through the skin)
  • Respiratory (inhaled)
  • Gastrointestinal (ingested)
  • Parenteral (intramuscular, intravenous or

8
Decontamination Methods
  • Gross
  • Dilution
  • Absorption
  • Neutralization
  • Isolation/disposal
