PREVIEW OF

HAZMAT TECHNICIANDECONTAMINATION

POWERPOINT TRAINING PRESENTATION

OBJECTIVES

Define Contamination & DecontaminationIdentify different contaminants & Routes

of contaminationUnderstand the concepts of exposure &

contaminationIdentify the physical & chemical methods

of decontamination

OBJECTIVES

Given a simulated hazardous materials scenario, as a team, demonstrate the ability to set up a contamination reduction corridor and perform decontamination

EXPOSURE vs. CONTAMINATION

A person who has been contaminated may have not been exposed

The term exposure is used to differentiate between simple contact & contact with the potential of causing harm or illness

HEALTH EFFECTS

Acute Start when you come in contact with hazmat Can be temporary, or become chronic or fatal Small amounts of some hazmats can be

immediately fatal

METHODS OF DECONTAMINATION

Dilution/washing Most commonly used method of decontamination Simple use water (maybe with soap) to dilute & wash off contaminant Add a little scrubbing and most contaminants will wash offExample

Washing hands

METHODS OF DECONTAMINATION

Isolation/disposal Simple as putting

contaminant in bag or drum

Often end stage beforetransporting

Often expensive to dispose of

METHODS OF DECONTAMINATION

Solidificationaka Dry Decontamination Used when it involves low-toxicitymaterials & vapors, gas, or has a high vapor density Used for removing PPE when task has been completed

DECISION MAKING

Fast BreakQuick emergency decon of

contaminated patientsLong Term

Slow planed decon of all

MASS DECONUsed only for decon

of victimsOften used in WMD

incidentsCan go from a simple hose to multiple engine companiesHardest part is keeping deconed victims from contaminated

victimsConvincing victims of necessity may be difficult

ONE STAGE AT A TIME

Decon area should be divided into stages Number determined by contaminate &

resources availableEntry at hot zone with exit in cold zoneDesign should be systematic with care

taken not to contaminate stages further out

DECON AGENTS

Isopropyl alcoholUsed with isocyanates Can be flammable

WATER REACTIVITY

Will it react with water?Examples

Sodium metalLime powder

Placard Group 4 chemicalsCan they be dusted, blown, or vacuumed off the body?

CONTAINMENT

Can runoff be contained?

PROPER PROCEDURES

Have procedures been preplanned for decon station?

EQUIPMENT DROP

First stop in decon areaUsed to deposit contaminated tools

SHOWERSUsed to rinse contaminant off ` PPE or patient

DECON TEAM LEADER

Ensures entry team is deconed in proper order

Watches for cross contaminationOversees removal & isolation of

contaminated PPE Monitors overall effectiveness & safety of

decon operation

SPECIAL SITUATIONS

RadiationInfectious agentsTerrorismPesticides

TRANSPORT

Patients may not be fully deconedLimit number of ambulances usedRemove non-essential equipmentWrap victim in plasticCover floor & walls in plastic
