1 Program Objectives Define “Decontamination”.
Identify the steps in the decon process. Demonstrate, by building, a decontamination reduction zone.

2 Decontamination The process of removing or neutralizing contaminants that have accumulated on personnel or equipment.

3 Exposure versus Contamination
The subjection of a person to a toxic substance or harmful physical agent through any route of entry. Common cold, TB Contamination: The transfer of a hazardous material to persons, equipment, and the environment in greater than acceptable quantities. Alpha particle, splash

4 Types of Contamination
1. Surface contaminates 2. Permeation

5 Five Factors which affect the extent of permeation
Contact Time Concentration Temperature Size of contaminant vs. pore space Physical State of Waste or Haz-Mat

6 Prevention of Contamination
Establish Standard Operation Procedures (SOPs) to minimize contact with hazardous materials. Stress “Clean” work practices. Use disposable outer garments when appropriate. Use remote sampling, handling, and container opening techniques. Protect monitoring instruments with bags

7 Emergency Decontamination
The physical process of immediately removing dangerous contaminates from individuals. Very rapid, gross decon. Remove clothes, wash with available water, cover, treatment/transport.

8 Decontamination Plan Determine the number and layout of the Decon stations. Determine equipment and materials needed to effectively remove contaminants Determine the appropriate Decon solution(s). Establish procedures to prevent contamination of clean areas.

9 Decontamination Plan (cont’d.)
Minimize worker contact with contaminants during removal of PPE. Establish proper disposal of contaminated materials.

10 DECONTAMINATION METHODS
ABSORPTION ADSORPTION CHEMICAL DEGRADATION DILUTION DISPOSAL ISOLATION NEUTRALIZATION SOLIDIFICATION

11 Testing the Effectiveness of the Decontamination Process
Visual Observation Wipe Sampling Cleaning Solution Analysis Testing for Permeation

12 Decontamination Facility Design
The level and type of Decon depends on several site-specific factors: The physical, chemical, and toxicological properties of the contaminant The amount, location, and containment of the released contaminant The movement of personnel and equipment among different zones

13 Decontamination Zones
There should be three zones when responding to chemical emergencies. Exclusion, Contamination Reduction, and Support Exclusion Exclusion CRZ Support

14 HazMat Zones Wind/Grade Cold Warm Hot

15 Contamination Reduction Zone
Wind/Grade Drum Drum Pool Suit Removal Exit Med check Tool Drop Entry

16 Let's go build one...
