Module 4 Unit 1Decontamination

Unit 4 - 2Florida Operational LevelHazardous Materials Training Program

Objectives

Identify appropriate level of protection identify was objects become contaminated identify various methods of

decontamination describe emergency decontamination identify appropriate methods for dealing

with contaminated patients

Unit 4 - 3Florida Operational LevelHazardous Materials Training Program

Objectives (cont)

Demonstrate emergency decontamination perform technical decontamination

Unit 4 - 4Florida Operational LevelHazardous Materials Training Program

Types of contamination

Direct Contaminationcontact with product or vapors

Cross Contaminationcontact with a contaminated object

Unit 4 - 5Florida Operational LevelHazardous Materials Training Program

Assessment of Contamination

Proper training and training Proper protection Physical and chemical properties

is it needed type required

Unit 4 - 6Florida Operational LevelHazardous Materials Training Program

Decontamination methods

Dry- brushing, removing, vacuumingdoes not involve liquidsusually the first step of decon process important if chemical is water reactive

wet decontamination- flushing, dilutioncommonly uses water

dilution or physical removal by flushing

Unit 4 - 7Florida Operational LevelHazardous Materials Training Program

Decontamination Methods (cont)

If material is not water solubleThen surfactant must be usedLaundry detergent is common

Unit 4 - 8Florida Operational LevelHazardous Materials Training Program

Gross Decontamination

Occurs at edge of Hot Zone leaves bulk of contamination in Hot Zone Combination of methods Hands off process Advantages:

minimizes the risk through the rest of process lowers possibility of exposure to vapors

Unit 4 - 9Florida Operational LevelHazardous Materials Training Program

Secondary Decontamination

Occurs after Gross, in Warm Zone Systematic head to toe removal Methods: usually wash followed by rinse

and removal of PPE Hands-off until wash and rinse is done Process will vary

Unit 4 - 10Florida Operational LevelHazardous Materials Training Program

Tertiary Decontamination

Fine removal of remaining contaminants usually performed at hospital includes- hygiene showers, skin

debridement, dialysis, surgical interventions

Unit 4 - 11Florida Operational LevelHazardous Materials Training Program

Emergency Decontamination

Rapid removal of contaminants Advantages

Requires minimal special equipmentPerformed by operational level respondersEnables rapid medical treatmentminimizes risk down stream

Unit 4 - 14Florida Operational LevelHazardous Materials Training Program

Technical Decontamination

A through step by step process used to remove contaminates from responders or victims in a non-urgent manor.More through removal of contaminationMethods will vary with chemicalTechnician level assistance is required

Unit 4 - 15Florida Operational LevelHazardous Materials Training Program

Mass Decontamination

Rapid flush of large number of victims Methods- single engine or multiple engine considerations

Fire Control

Fire Fighting Foamadvantages

Unit 4 - 26Florida Operational LevelHazardous Materials Training Program

Foam Characteristics

Hydrocarbon/ polar solvent/ Multi use

protein/ synthetic based

expansion ratios re-ignition/ burnback

resistance water retention

Heat resistance protection from

freezing compatibility with dry

chemical viscosity can be pre-mixed fuel shedding capability

Unit 4 - 27Florida Operational LevelHazardous Materials Training Program

Protein Foam

3-6% made from animal protein good re-ignition resistance excellent water retention may freeze may add anti-freeze

Unit 4 - 28Florida Operational LevelHazardous Materials Training Program

Flouro-protein Foam

3-6% Excellent fuel shedding long term vapor suppression good water retention long heat resistance low viscosity excellent for sub-surface injection

Unit 4 - 29Florida Operational LevelHazardous Materials Training Program

AFFF

1, 3-6% synthetic based good penetrating abilities may use non-aerating nozzles low viscosity can be pre-mixed multi-purpose

Unit 4 - 30Florida Operational LevelHazardous Materials Training Program

Application Rates

May vary between manufactures different for ignited spills calculate and assemble needed amount

before beginning application must be faster than destruction rate

Unit 4 - 31Florida Operational LevelHazardous Materials Training Program

General Guidlines

AFFF and FFFP= .10 GPM solution psf Polar Solvents= .24 GPM solution psf Protein and Flouro-protein= .16 GPM Non-ignited require lower rates
