  1. Unit 5.2 MISSION SPECIFIC: Technical Decontamination

  2. Decontamination • Contamination • Direct • Secondary • Exposure vs. contamination Unit 5.2  2

  3. Decontamination A systematic process of removing contaminates from victims, responders or equipment in order to reduce exposure and prevent the spread of contamination Unit 5.2  3

  4. Decontamination • Types • Emergency decontamination • Mass decontamination • Technical decontamination • Based on chemical and situation Unit 5.2  4

  5. Decontamination Methods • Wet or Dry • Absorption • Adsorption • Chemical degradation • Dilution • Disinfection • Evaporation • Isolation and disposal • Neutralization • Solidification • Sterilization • Vacuuming • Washing Unit 5.2  5

  6. Stages of Decontamination • Gross • Takes place at the edge of the hot zone • Goal: Remove bulk contaminates and leave them in the isolation area • Combination of dry methods Unit 5.2  6

  7. Stages of Decontamination • Secondary decontamination • Occurs after gross decontamination has been completed • Is conducted in the warm zone • Goal: Systematic removal of contaminates in a head to toe fashion • Involves a thorough wash, rinse and removal of protective equipment Unit 5.2  7

  8. Stages of Decontamination • Tertiary decontamination • Removal of remaining contaminates • Usually happens in health care facility • May be accomplished by personal shower Unit 5.2  8

  9. Additional Considerations • Preservation of evidence • Tools and equipment including weapons • Animals and criminal suspects • Ambulatory victims • Non-ambulatory victims • Contain runoff • Determine the effectiveness of decontamination Unit 5.2  9

  10. Emergency Decontamination • Life threatening emergency • Strip and flush • Medical treatment • Secondary decontamination • Runoff not an issue Unit 5.2  10

  11. SERC Model • Nine Basic Steps • Tool drop • Outer glove/boot removal • Gross wash (hot zone) • Primary wash/rinse • Final wash/rinse • Garment removal • Go off-air station • Inner glove/face piece • Rehab and medical evaluation Unit 5.2  11

  12. Mass Decontamination • Goal: Rapid flush of large numbers of victims in order to reduce the likelihood of the spread of contamination or long term adverse health effects • Methods: Numerous methods exist • Single engine company • Multiple engine company Unit 5.2  12

  13. Mass Decontamination • Considerations • Large numbers of panicked people may be encountered; scene control will be a major concern • Use of hand lines and deck guns in a controlled and safe manner is necessary • These are hands-off operations; getting too close to a panicked crowd can be dangerous Unit 5.2  13

  14. Video “Technical Decontamination” Unit 5.2  14

  15. Summary • Types of decontamination • Methods of decontamination • Stages of decontamination • PPE considerations Unit 5.2  15

  16. Activity 5.2 Field Evolution – Establish Technical Decontamination Unit 5.2  16
