CBRN Awareness

Chemical, Biological, Radiological, and Nuclear.

Mission Oriented Protective Posture.

MOPP 0 through MOPP 4, ranging from IPE (Individual Protective Equipment) available and accessible (MOPP 0) to full protective gear worn (MOPP 4).

IPE is issued and available within the work area. Overgarment, boots, mask, and gloves are accessible but not worn.

Overgarment (suit) worn, overboots carried. Mask and gloves carried.

Overgarment and overboots worn. Mask and gloves carried.

Overgarment, overboots, and mask worn. Gloves carried.

All protective equipment worn: overgarment, overboots, mask, and gloves.

Joint Service Lightweight Integrated Suit Technology.

Nerve agents, blister agents, blood agents, and choking agents.

Vapors, solids, liquids, and gases.

Three categories: persistent, non-persistent, and dusty.

Arterial spray, artillery bombs, individual dissemination, mines, and rockets.

Runny nose, headache, drooling, vision difficulty, chest tightness, localized sweating, stomach cramps, nausea, and heart rate changes.

Confusion, wheezing, pinpointed pupils, tearing, vomiting, muscular twitching, involuntary urination/defecation, convulsions, unconsciousness, respiratory failure, and bradycardia.

The Antidote Treatment, Nerve Agent Autoinjector (ATNAA).

3 doses.

10 seconds.

Stick it through the pocket flap to track the number of injections given.

Audible alarms, automatic alarms, and visual signals.

After you mask first, then sound the alarm. Self-protection comes before warning others.

Stop breathing, close your eyes, don the mask, clear the mask, check the seal, sound the alarm, and continue the mission.

Ammonia vapors and carbon monoxide.

The unit commander.

Immediate hazards and residual hazards.

Avoid contamination, protection, and decontamination.

Immediate, operational, and thorough.

FM 3-11.

FM 3-11.4.

FM 3-5.

NBC Handbook.

Initial detection and reporting of NBC weapons usage by the enemy.

Air burst, ground burst (surface), and subsurface burst.

1 quart or more per hour due to heat stress.

Forehead straps, cheek straps, then temple straps.

Personal hygiene.

An insect or organism used to disseminate biological agents.

The intentional use of germs or toxins from living organisms to cause death and disease among people, animals, or plants.

Bacteria, fungi, rickettsiae, and viruses.

Warm soapy water.

Stirring up dust and touching anything.

FM 3-11.3.

The current-issue joint-service general purpose protective mask that provides respiratory, eye, and face protection against CBRN agents, toxins, and radioactive particles.

The M50 provides protection in confined spaces, but oxygen-deficient environments require a self-contained breathing apparatus (SCBA) instead.

Detecting liquid chemical agents. It changes color when exposed: yellow for G-series nerve agents, red for H-series blister agents, and dark green for V-series nerve agents.

Triangular markers placed with the point facing the contaminated area.

Yellow background with red lettering for chemical (GAS), blue background with red lettering for biological (BIO), white background with black lettering for radiological (ATOM), and black background with red lettering for chemical mines.

Thermal radiation (flash/heat), blast wave (overpressure), nuclear radiation (initial and residual), and electromagnetic pulse (EMP).

Residual radioactive material propelled into the upper atmosphere following a nuclear blast that falls back to the surface. It can contaminate large areas downwind of the detonation.

Time (minimize exposure time), distance (maximize distance from source), and shielding (use dense materials to block radiation).
