Is the first major difference between HAZMAT situation and a CBRN incident number of expected victims
Questions to be asked before initiating decon: Can decon be done safely? Are existing resources adequate? What are the agents to be contaminated? What are the existing and forecast weather? What is the terrain?
Methods of decon physical, chemical, prevention
Decon effectiveness can be assessed by levels of contamination reduced, contamination confined to hot zone prior to vapor line, contamination is reduced to ALARA
Three fundamental stages of decontamination Primary- gross contamination removal; Secondary- residual contamination removal; Tertiary- PPE removal and personal shower
mass decon is a multi-stage, resource intensive process
Single most important step in decon which removes 50-80% of contaminent Removing chothes
What percent of the contaminent is removed just by removing clothing 50-80%
