CBRN Test UPDATED Exam Questions and
CORRECT Answers
Describe the proper way to stow the M50 Joint-Service General Protective Mask (JSGPM) in the
mask carrier - CORRECT ANSWER - Place in the carrier eyelens first, covered by the
head harness skullcap, facing away from the body
Heat Stress - CORRECT ANSWER - Wearing all MOPP overgarments adds 10 degrees
Fahrenheit (F)
Provide the most correct definition of Mission-Oriented Protective Posture (MOPP) - CORRECT
ANSWER - A flexible system of IPE and clothing that provides the maximum CBRN
protection with the lowest risk to
achieve mission accomplishment
Mask Only - CORRECT ANSWER - Worn with the long-sleeve duty uniform.
Mask Only is a flexible option of the MOPP system for commanders.
The Mask Only command is given under certain situations to include when Riot Control Agents
(RCAs) are employed, and when no non-persistent CB threat exists.
Commanders should never direct a Mask Only posture when under threat of a possible
downwind vapor hazard of a persistent chemical or biological agent.
JSLIST Suit - CORRECT ANSWER - Provides a maximum of 24-hours of protection
after contamination from chemical agents.
Service life of 120 days (during the 120 days, the suit may be physically worn for a total of 45
days).
The barrel lock release button on the coat hood must face away from you when worn to avoid the
barrel lock from unfastening and possibly exposing you to contamination.
Following checked items would render the JSLIST Trousers or JSLIST Coat not fully mission
capable. - CORRECT ANSWER - The total number of launderings is not annotated on the
coat lapel.
,The hood has a rip along the edge.
A barrel lock on the hood draw-cord missing.
To go to MOPP III, after donning MOPP II. - CORRECT ANSWER - 1) Don FPM and
check seal.
2) Pull hood over FPM.
3) Close slide fastener and secure hook-and-pile tape.
4) Place and secure hod around edge of FPM.
5) Snap barrel locks under chin.
6) Check hood seal by another Marine.
Mission-oriented protective posture (MOPP) provides commanders a flexible system of
individual protective equipment (IPE). Being in the correct MOPP Level appropriate to the
CBRN risk hazard, will protect you from becoming a casualty while enabling you to complete
the task or mission. Which of the following is correct when it comes to MOPP? - CORRECT
ANSWER - More protection is provided at higher MOPP levels, but at the cost of
performance degredation.
CBRN Alarm and Warning Guidelines - CORRECT ANSWER - 1) Give the alarm as
soon as an attack is detected.
2) Use an alarm method that cannot be confused easily with normal combat signals or sounds.
3) Everyone who hears or sees the alarm must repeat it swiftly.
4) Supplement the alarm by passing it over radion and any other communications capability.
Visual Alarm - CORRECT ANSWER - Astandard hand-and-arm signal always used in
combination with the vocal alarm during a CBRN attack.
Move your fists rapidly to your head and back to the horizontal position.
Sound Alarms - CORRECT ANSWER - Beating an object
Short blasts
, Siren
During a battle, where the combat noises obscure the vocal alarms and beating an object sounds,
the following sound alarms would be appropriate to announce the presence of chemical
contamination. - CORRECT ANSWER - Short blasts on a vehicle horn in 1:1 seconds on-
off ratio.
CBRN-1 Observer's Report - CORRECT ANSWER - Is an essential component of the
CBRN Warning and Reporting System (CBRNWRS).
The first CBRN-1 Report of each attack is sent with FLASH (Z) message precedence.
Subsequent messages, with IMMEDIATE (O).
Three set identifiers - Mandatory (M), Operationally Determined (O), and Conditional (C).
Five mandatory sets- Mandatory (M), Operationally Determined (O), and Conditional (C).
CBRN Contamination Markers - CORRECT ANSWER - Yellow sign = Gas
Blue Sign = Biological
White Sign = Radiological Contamination
A NATO CBRN contamination marker's colors and lettering will indicate the type of
contamination. Additional information must be recorded on the marker on the front of the
marker, on the same side as the marker's lettering. This information is required on both Chemical
and Biological NATO Contamination markers. - CORRECT ANSWER - The date and
time when the contamination was detected.
M8 VGH Chemical Agent Detector Paper - CORRECT ANSWER - Consists of 25 sheets
of chemically treated paper, may be torn in two in order to conduct 50 separate tests. Responds
by changing color within 30 seconds of exposure to nerve and blister agents.
Yellow= The presence of a G nerve agent.
Green= Indicates a V nerve agent.
Red= H, L or CX blister agents.
