CBRNE/HAZMAT Flashcards
Primary types of biological warfare
Viruses
Bacteria
Toxins
Chemical warfare agents
Vesicants (blister agents) Respiratory or choking agents Nerve agents Metabolic or blood agents Irritating/inflammatory agents
Characteristics of chemical weapon agents
Liquid
Gas
Solid
Persistency and volatility (how long the agent will stay on a surface before it evaporates)
DUMBELS nerve agent mnemonic
Defecation Urination Miosis Bradycardia, Bronchorrhea, Bronchoconstriction Emesis Lacrimation Salivation
Rule of thumb for HAZMAT scene safety
If the HAZMAT scene cannot be covered by your thumb while the arm is extended out, you’re too close!
NFPA 704 hazardous materials ranking
Ranked based on health hazard or toxicity levels, fire hazard, chemical reactive hazard, and special hazards (radiation, acids, etc)
Toxicity levelling system
Level 0: little or no hazard Level 1: slightly hazardous Level 2: slightly hazardous Level 3: extremely hazardous Level 4: minimal exposure causes death.
Safety zones for HAZMAT
Hot zone: contamination zone
Warm zone: surrounds hot zone, area where decontamination typically occurs
Cold zone: further buffer from hazards. Typically where triage and treatment would occur.
Primary contamination
Direct exposure of patient to HAZMAT
Secondary contamination
When hazmat is transferred from person to person or from contaminated objects
4 methods of decontamination
Dilution
Absorption
Neutralization
Disposal
