6
Overview

• Decontamination theory
• Standard plan
• Provide protection to all
• Hazmat Specialist coordinates DECON
• Emergency DECON is four steps
• DECON layout

7
Decontamination Theory Overview

• Time consuming
• Personnel and equipment intensive
• For USR personnel and rescued victims or as
  directed
• Evidence preservation
• Decon equipment provided to TFs is based on
  mission requirement

8
Working Definition of Decontamination

• A chemical and/or physical process to remove and
  prevent the spread of a contaminant.

9
Decontamination

• Prompt, safe, and effective decontamination
  protects against and reduces effects of exposure.
• Believe it or not, you have a role in this.

10
Decontamination Situations

• Obvious contamination with known hazardous
  substance
• Suspected contamination with a hazardous
  substance
• Any likelihood of exposure to a hazardous
  substance
• Prevent spread of contaminant
• Environmental protection

11
Perform DECON by Priority

• TF members and canines who are ill, symptomatic,
  or have compromised PPE
• Rescued survivors
• TF Members with intact PPE and canines who are
  asymptomatic

12
Decontamination Process

• Hazmat Specialists supervise decontamination
  process
• Primarily to protect Task Force
• Decontamination is always confirmed with
  monitoring equipment
• Survivor decontamination
• Everyone goes through some level of
  decontamination
• This provides protection against contamination
  spread to EMS, hospitals, etc.

13
Types of Decontamination

• Emergency
• Gross Decon
• Field Decon Kit
• Technical
• CPC
• Personnel
• Vehicles
• Equipment
• Canine

14
Emergency Decontamination

• Fire Hose near point of Entry/Exit
• Field Decontamination Kit
• Design system per the mission

15
Field Decontamination
16
Technical Decon

• Multi Step process
• Gross Wash
• Wash Rinse
• Doffing of CPC Respiratory Equipment
• Metering/Screening
• Medical Assessment
• Personal Shower

17
Technical Decontamination Equipment

• Buckets, brushes, and soap
• DECON solution and containment system
• Dedicated water supply
• Trash containers

18
Technical DECON Equipment (cont)

• Electrical extension cords water hoses
• 500-600 gallon waste bladders
• Run-off and waste water pumps
• Gross DECON showers
• Modular DECON Tent

19
Technical DECON Equipment (cont)

• Canopies/Tents
• Air space heater
• Water Heater
• Generators
• Tube lighting
• Work lights

20
Technical DECON Equipment, Cold Weather Use

• Tents with Sidewalls
• Space heater
• Hot water heater
• Zippers for entrance and exit
• May need a Event Tent if weather is severe to
  cover the entire corridor
• IST or Local Jurisdiction Help

21
Technical DECON Equipment, Cold Weather Use
Water Heater

• Portable
• 60F to 105F at 16 gpm
• Fuels - diesel, JP-4, JP-8, or kerosene
• Solid state ignition - ignites when water flows
• Onboard pressure reducing valve

22
Technical DECON Equipment, Cold Weather Use
Forced Air Space Heater

• Portable with wheels and handles
• Provides breathable heated air -110,000 btu
  output, 850 cfm fan
• Multi-fuel (kerosene, diesel, fuel oil, JP 4/8)
• 16 hours on 1 tank of fuel

23
Specialized DECON Equipment

• MERLIN foam generator
• Hazmat Specialist can arrange for solutions as
  needed
• Requires a 3 year service by manufacturer

24
Standardized DECON Staffing

• DECON supervised by Hazmat Specialist
• DECON positions filled by any available personnel
• All Task Force members receive basic DECON
  training
• Medical Specialist conducts Triage

25
Decontamination Supervisor

• Responsible for final walkthrough of corridor
• Ensures supplies are present
• Addresses runoff containment
• Ensures safe, efficient and effective operations

26
Medical DECON Liaison

• Responsible for medical assessment and treatment
• Liaison with DECON supervisor
• Positioned to observe all persons leaving
  exclusion zone

27
When assigned to DECON

• Don selected level of PPE/CPC
• Operate in PPE/CPC
• Establish operating time log
• Setup and operate DECON line
• Conduct triage
• Communicate while in PPE

28
Standardized TF DECON Site Layout

• Situated upwind from the exclusion zone
• Locate uphill, drain toward exclusion zone
• or to side
• Large enough to keep clean from contamination
• Place heaters upwind and uphill to help avoid
  contamination
• Plastic bags on hand to collect personal items

Decontamination process for PPE/CPC

• Rinse, head to foot-Gross Wash
• Scrub suit with brush, head to foot-wash/Rinse
• Attend to heavily contaminated areas (hands,
  feet, front of suit)
• Rinse again, head to foot
• Assist member in removing CPC(Do not reach
  inside, roll CPC down from outside)

31
USR Standard DECON Process

• Step One Gross DECON (Shower)
• Step Two - Wash and Rinse
• Modular pre-plumbed 3 lane shower
• Step Three- Remove Outer Protection
• Respiratory protection removed last
• Meter to determine DECON efficiency
• Medical Monitoring
• Step Four Personal Hygiene Shower

32
Step 1. Gross Decon

• Rinse thoroughly in shower

33
Step 2. DECON Wash and Rinse

• Scrub clean (helpers on hand)
• Person spread arms and legs, rotate for cleaning

34
Step 2. DECON Wash and Rinse (cont)

• Wash from top down
• Assistants must DECON themselves before they
  leave corridor

35
Step 3. Remove Outer Protection

• Remove CPC not respiratory protection
• Place CPC in container for disposal
• Prevent cross contamination
• Turn CPC inside out as it is removed
• Peel CPC off rescuer without touching inside of
  CPC
• Remove respiratory protection after leaving area

36
Step 4. Personal Hygiene

• May be on or off site
• Personnel must be clean before evacuation
• Personal hygiene can range from hand washing to
  showering

37
Post DECON Monitoring

• Personnel exiting DECON checked with monitoring
  instruments by Hazmat Specialists
• If contaminants still present after removing CPC,
  or working in known contaminants, then personal
  hygiene is high priority

38
Post DECON Considerations

• Medical Evaluation
• Rehabilitation and replacement clothing
• Reports and exposure logs
• Hazmat tracking

Documentation is Critical
39
Water Run Off Considerations

• Berms
• Sump Pumps
• Water Bladders
• Plastic Sheeting
• The EPA position on runoff states that you can
  avoid capturing waste water in an emergent life
  safety situation.

40
DECON Water Disposal

• Collected water should be removed by an
  appropriate agency(s) or contractor
• Ask for established policy as per
• DECON Plan
• IST
• EPA
