Which CBRN warning and reporting system is used by Marine Corps units to disseminate CBRN attack information?
Answer: CBRN Spot Report (CBRN-1 through CBRN-6)
CBRN-1 through CBRN-6 report formats are used to report, warn, and track CBRN incidents across Marine Corps units.
What is the significance of the 'upwind' position when establishing a decontamination station?
Answer: It prevents airborne contamination from blowing onto clean personnel and equipment at the station
Positioning the decon station upwind prevents wind-carried contamination from re-contaminating personnel and equipment that have already been decontaminated.
A Marine exhibits miosis (pinpoint pupils), excessive salivation, and muscle twitching after potential agent exposure. Which agent class do these symptoms indicate?
Answer: Nerve agent (organophosphate)
Miosis, hypersalivation, and fasciculations are classic signs of cholinergic crisis caused by nerve agent (organophosphate) inhibition of acetylcholinesterase.
In nuclear weapons effects, what is 'fallout' and when does it primarily threaten forces?
Answer: Radioactive particles deposited downwind after a surface or near-surface burst
Fallout consists of radioactive particles lofted into the atmosphere by a surface or near-surface burst that deposit downwind, threatening forces well beyond the initial blast zone.
What is the correct procedure when M8 chemical agent detector paper turns yellow-green upon contact with a liquid?
Answer: Report possible nerve agent contamination and increase MOPP level
M8 paper that turns yellow or green indicates the presence of G-series (nerve) agents; red indicates V-series nerve agents; and dark red or black indicates blister agents.
Which principle of CBRN defense involves restoring personnel and equipment to an acceptable level of contamination while sustaining combat operations?
Answer: Decontamination
Decontamination reduces contamination to acceptable levels, allowing sustained combat power even in a CBRN environment.
When a unit transitions from a contaminated to an uncontaminated area, what action is required before removing MOPP gear?
Answer: Conduct immediate decontamination and receive clearance from the CBRN officer
Units must conduct decontamination and receive clearance from the CBRN officer or qualified monitor confirming it is safe before reducing MOPP level.
