CRNBe Flashcards
What does CBRNe stand for?
Chemical, Biological, Radioactive, Nuclear, Explosive
Define CBRNe.
Term for protective measures taken when any of these hazards exist, accounting for CBRN passive protection, avoidance, and mitigation.
What are some common incapacitating chemical agents?
- Bromobenzylcyanide (CA gas)
- Capsaicin (OC)
- Chloracetophenone (MACE; CN)
- Ortho-chlorobenzylidene malononitrile (Super tear gas; CS)
- Adamsite (DM) (Vomiting agent)
- Skunk Weapon (Malodorants)
List some common lethal chemical agents.
- Sarin gas
- Tabun gas (Nerve agents)
- Bis(2-chloroethyl) sulfide (Mustard gas; HD)
- 2-Chlorovinyldichloroarsine (Lewisite; L)
- Chlorine
- Diphosgene
- Phosgene (Choking agents)
What are the signs and symptoms of chemical exposure?
- Bronchorrhea
- Bronchospasm
- Severe skin, eye, and mucosal irritation
- Nausea/Vomiting
- Blistering to affected areas
- Mild to severe respiratory distress
What is the treatment for chemical exposure?
- Scene safety
- Proper decontamination
- Oxygen
- OPA, NPA, etc.
- IV
- Supportive measures
- ALS-Atropine, Pralidoxime (2-PAM), Diazepam
Define biological agents.
A bacterium, virus, protozoan, parasite, or fungus that can be used as a weapon.
List some biological agents commonly found.
- Anthrax
- Cholera
- Diphtheria
- Small Pox
- Ricin
- Botulinum toxin
What are the signs and symptoms of biological toxins?
Can range from mild anaphylaxis to serious medical conditions, including death.
What is the treatment for biological agents?
- Scene safety
- Proper decontamination
- Oxygen
- OPA, NPA, etc.
- IV
- Supportive measures (vitals, ECG, 12 lead)
- Hospital treatment will include antibiotics, antivirals, antifungals, etc.
What are the types of radiation associated with radiological/nuclear emergencies?

What is the treatment for radiological/nuclear exposure?
- Shielding of yourself and patient until properly decontaminated
- Oxygen
- IV
- ECG and 12 leads
- Supportive measures
- Transport
What are the classes of protective equipment for CBRNe?
- Class A: NIOSH approved filter mask with splash resistant clothing
- Class B: SCBA with splash resistant clothing
- Class C: SCBA with a one piece, splash resistant and sealed suit
- Class D: SCBA worn under a fully encapsulated suit that is completely sealed
How is triage for CBRN incidents different from other incidents?
In a chemical incident, we do not treat the dead as black but as red because usually with aggressive treatment, they can be salvaged.
What are the zones in a CBRN incident?
- Isolation Zone
- Hot Zone
- Warm Zone
- Cold Zone
What is the hot zone in a CBRN incident?
The area within the building that the incident originated.
What is the cold zone in a CBRN incident?
The area where first responders not immediately involved in the incident are waiting to be tasked or for transport.
