FMF CBRN Defense Procedures 2 — Questions and Answers
Question 1: Which MOPP level requires donning the protective mask and hood in addition to the suit?
- MOPP 1
- MOPP 2 (Correct answer)
- MOPP 3
- MOPP 4
Correct answer: MOPP 2
MOPP 2 requires the protective suit and boots to be worn plus the mask and hood to be carried ready, while MOPP 3 adds the mask and hood as donned items.
Question 2: In a CBRN environment, what does the term 'contamination avoidance' primarily mean?
- Decontaminating all equipment immediately after exposure
- Preventing contact with CBRN hazards through planning and movement (Correct answer)
- Wearing full MOPP 4 at all times during operations
- Evacuating all personnel from the operational area
Correct answer: Preventing contact with CBRN hazards through planning and movement
Contamination avoidance focuses on preventing contact with CBRN hazards through route selection, early warning, and tactical movement to minimize exposure.
Question 3: Which nerve agent antidote combination is contained in the ATNAA (Antidote Treatment Nerve Agent Auto-injector)?
- Atropine and pralidoxime chloride (2-PAM Cl) (Correct answer)
- Diazepam and atropine
- Pyridostigmine bromide and atropine
- Hydroxocobalamin and 2-PAM Cl
Correct answer: Atropine and pralidoxime chloride (2-PAM Cl)
The ATNAA combines atropine (to block muscarinic effects) and pralidoxime chloride (to reactivate cholinesterase) in a single auto-injector.
Question 4: What is the primary purpose of the Toxic Industrial Chemical (TIC) hazard guide in CBRN planning?
- To identify enemy chemical weapons stockpiles
- To assess hazards from industrial facilities that could be weaponized or accidentally released (Correct answer)
- To classify all military chemical agents by lethality
- To establish decontamination procedures for biological agents
Correct answer: To assess hazards from industrial facilities that could be weaponized or accidentally released
TIC hazard guides help planners assess risks from industrial facilities whose chemicals could be accidentally released or deliberately weaponized by adversaries.
Question 5: Which biological agent characteristic makes spore-forming agents like anthrax particularly dangerous in a CBRN context?
- They are easily neutralized by standard decontamination solutions
- Spores remain viable in the environment for decades (Correct answer)
- They only affect unvaccinated individuals
- They require direct skin contact to cause infection
Correct answer: Spores remain viable in the environment for decades
Anthrax spores can remain viable in soil and on surfaces for decades, making area denial and decontamination extremely challenging.
Question 6: During a chemical attack, what is the correct sequence for donning the protective mask?
- Stop breathing, don mask, clear, check seal (Correct answer)
- Exhale fully, place mask on face, inhale sharply, adjust straps
- Don mask, clear, check, inhale deeply
- Cover nose and mouth first, then slide mask over head
Correct answer: Stop breathing, don mask, clear, check seal
The correct sequence is stop breathing (or hold breath), don the mask, clear it by exhaling sharply, then check the seal before resuming normal breathing.
Question 7: What does the M8A1 Automatic Chemical Agent Alarm detect?
- Biological toxins and radioactive particles
- Nerve and blister agent vapors (Correct answer)
- Radiological contamination levels
- All CBRN hazard types simultaneously
Correct answer: Nerve and blister agent vapors
The M8A1 automatically detects nerve agent (G and V series) and blister agent (H series) vapors and sounds an alarm.
