This handbook was first produced by the Chemical, Biological and Radiological (CBRN) Subcommittee in June 1995. The subcommittee is one of seven subcommittees of the Interagency Intelligence Committee on Terrorism (IICT). Established and charged under DCI Directive 3/22, 24 October 1990, the IICT is comprised of representatives from 45 US Government agencies and organizations from the intelligence, law enforcement, regulatory, and defense communities. The IICT and its subcommittees provide an interagency forum for coordination and cooperation on a wide spectrum of counterterrorism and antiterrorism issues.
This edition of the handbook earmarks the addition of information pertaining to radiological incidents. This update reflects the collective efforts of each agency represented on the CBRN Subcommittee to provide critical information on new and evolving trends necessary to understanding and dealing with changing counterterrorism issues. In particular, I wish to thank the Nuclear Regulatory Commission, the Defense Intelligence Agency, the Federal Emergency Management Agency, the Public Health Service and the Central Intelligence Agency for the major role they played in the update of this handbook.
Lastly, I want to recognize the CBRN Subcommittee's dedication in providing timely assessments and information to a myriad of organizations committed to counterterrorism. I hope that this handbook will play a useful role in these endeavors.

This handbook is intended to supply information to first responders for use in making a preliminary assessment of a situation when a possible chemical, biological agent or radiological material is suspected. When evaluating and taking action against a possible chemical, biological, or radiological incident, your personal safety is of primary concern.
A concise list of observable indicators of the use and/or presence of CBR material is included to aid in the assessment.
Once a decision is made that the incident may involve CBR material, the checklist, found in Section F, should be completed and forwarded to the appropriate authority for coordinating the response to the incident.
A glossary of terms and a list of additional reference materials are included.
What Is the Difference Between a Chemical, Biological, or Radiological Event?
Chemical, biological, and radiological material as well as industrial agents can be dispersed in the air we breath, the water we drink, or on surfaces we physically contact. Dispersion methods may be as simple as placing a container in a heavily used area, opening a container, using conventional (garden)/commercial spray devices, or as elaborate as detonating an improvised explosive device.
Chemical incidents are characterized by the rapid onset of medical symptoms (minutes to hours) and easily observed signatures (colored residue, dead foliage, pungent odor, and dead insect and animal life).
In the case of a biological incident, the onset of symptoms requires days to weeks and there typically will be no characteristic signatures. Because of the delayed onset of symptoms in a biological incident, the area affected may be greater due to the migration of infected individuals.
In the case of a radiological incident, the onset of symptoms requires days to weeks and there typically will be no characteristic signatures. Radiological materials are not recognizable by the senses, and are colorless and odorless.
Specialized equipment is required to determine the size of the effected area and if the level of radioactivity presents an immediate or long-term health hazard. Because of the delayed onset of symptoms in a radiological incident, the affected area may be greater due to the migration of contaminated individuals.
The following sections contain indicators of chemical/biological/radiological material release and key information to relay to responding organizations. In attempting to collect this information your personal safety is your primary concern.
Personal Safety Considerations
When approaching a scene that may involve chemical, biological, or radiological materials the most critical consideration is the safety of oneself and other responders. Be cognizant that the presence and identification of hazardous agents may not be immediately verifiable, especially in the case of biological and radiological agents. The following actions/measures to be considered by first responders are applicable to either a chemical, biological, or radiological incident. The guidance is general in nature, not all encompassing, and its applicability should be evaluated on a case-by-case basis by the first responders.
Actions To Be Considered:
Decontamination Measures:
Indicators of a Possible Chemical Incident
Dead animals/birds/fish | Not just an occasional roadkill, but numerous animals (wild and domestic, small and large), birds and fish in the same area.
|
|
Lack of insect life | If normal insect activity (ground, air, and/or water) is missing, then check the ground/water surface/shore line for dead insects. If near water, check for dead fish/aquatic birds.
|
|
Physical Symptoms | Numerous individuals experiencing unexplained water-like blisters, wheals (like bee stings), pinpointed pupils, choking, respiratory ailments and/or rashes.
|
|
|
||
Mass casualties | Numerous individuals exhibiting unexplained serious health problems ranging from nausea to disorientation to difficulty in breathing to convulsions to death.

Indicators of a Possible Biological Incident
Unusual numbers, of sick or dying people or animals
|
Any number of symptoms may occur. As a first responder, strong consideration should be given to calling local hospitals to see if additional causalities with similar symptoms have been observed. Casualties may occur hours to days to weeks after an incident has occurred. The time required before symptoms are observed is dependent on the agent used and the dose received. Additional symptoms likely to occur include unexplained gastrointestinal illnesses and upper respiratory problems similar to flu/colds.
|
Unscheduled and unusual spray being disseminated | Especially if outdoors during periods of darkness.
|
Abandoned spray devices | Devices will have no distinct odors. |

Information To Be Reported
[The linked pages are not, nor were they intended to comprise, an online form. The form is provided, as it is in the printed handbook, as a worksheet people may use to record information regarding possible exposure to chemical, biological, or radiological materials. This information would help local authorites--medical, police, health, and others--who respond to the scene of a possible exposure to evaluate the situation. The three pages are provided as images for ease of printing; each is about 100K in size.]
Glossary of Chemical Terms
acetylcholinesterase | An enzyme that hydrolyzes the neurotransmitter acetylcholine. The action of this enzyme is inhibited by nerve agents.
|
aerosol | Fine liquid or solid particles suspended in a gas; for example, fog or smoke.
|
atropine | A compound used as an antidote for nerve agents. |
casualty (toxic) agents | Produce incapacitation, serious injury, or death. They can be used to incapacitate or kill victims. These agents are the choking, blister, nerve, and blood agents.
|
|
Substances that cause physical injury to the lungs. Exposure is through inhalation. In extreme cases, membranes swell and lungs become filled with liquid. Death results from lack of oxygen; hence, the victim is "choked"
|
|
Substances that cause blistering of the skin. Exposure is through liquid or vapor contact with any exposed tissue (eyes, skin, lungs).
|
|
Substances that interfere with the central nervous system. Exposure is primarily through contact with the liquid (skin and eyes) and secondarily through inhalation of the vapor. Three distinct symptoms associated with nerve agents are: pin-point pupils, an extreme headache, and severe tightness in the chest.
|
Blood Agents | Substances that injure a person by interfering with cell respiration (the exchange of oxygen and carbon dioxide between blood and tissues).
|
chemical agent | A chemical substance that is intended for use in military operations to kill, seriously injure, or incapacitate people through its physiological effects. Excluded from consideration are riot control agents, and smoke and flame materials. The agent may appear as a vapor, aerosol, or liquid; it can be either a casualty/toxic agent or an incapacitating agent.
|
cutaneous | Pertaining to the skin.
|
decontamination | The process of making any person, object, or area safe by absorbing, destroying, neutralizing, making harmless, or removing the hazardous material.
|
G-series nerve agents | Chemical agents of moderate to high toxicity developed in the 1930s. Examples are tabun (GA), sarin (GB), soman (GD), and GF.
|
Incapacitating agents | Produce temporary physiological and/or mental effects via action on the central nervous system. Effects may persist for hours or days, but victims usually do not require medical treatment. However, such treatment speeds recovery.
|
|
Produce nausea and vomiting effects, can also cause coughing, sneezing, pain in the nose and throat, nasal discharge, and tears.
|
|
Produce irritating or disabling effects that rapidly disappear within minutes after exposure ceases.
|
|
Compounds that have the predominant effect of depressing or blocking the activity of the central nervous system. The primary mental effects include the disruption of the ability to think, sedation, and lack of motivation.
|
|
Compounds that have the predominant effect of flooding the brain with too much information. The primary mental effect is loss of concentration, causing indecisiveness and the inability to act in a sustained, purposeful manner.
|
industrial agents | Chemicals developed or manufactured for use in industrial operations or research by industry, government, or academia. These chemicals are not primarily manufactured for the specific purpose of producing human casualties or rendering equipment, facilities, or areas dangerous for use by man.

|
nonpersistent agent | An agent that upon release loses its ability to cause casualties after 10 to 15 minutes. It has a high evaporation rate and is lighter than air and will disperse rapidly. It is considered to be a short-term hazard. However, in small unventilated areas, the agent will be more persistent.
|
organophosphorous compound | A compound, containing the elements phosphorus and carbon, whose physiological effects include inhibition of acetylcholinesterase. Many pesticides (malathione and parathion) and virtually all nerve agents are organophosphorous compounds.

percutaneous agent | Able to be absorbed by the body through the skin.
|
persistent agent | An agent that upon release retains its casualty-producing effects for an extended period of time, usually anywhere from 30 minutes to several days. A persistent agent usually has a low evaporation rate and its vapor is heavier than air. Therefore, its vapor cloud tends to hug the ground. It is considered to be a long-term hazard. Although inhalation hazards are still a concern, extreme caution should be taken to avoid skin contact as well.
|
protection | Any means by which an individual protects his body. Measures include masks, self-contained breathing apparatuses, clothing, structures such as buildings, and vehicles.
|
V-series nerve agents | Chemical agents of moderate to high toxicity developed in the 1950s. They are generally persistent. Examples are VE, VG, VM, VS, and VX.
|
|
|
vapor agent | A gaseous form of a chemical agent. If heavier than air, the cloud will be close to the ground. If lighter than air, the cloud will rise and disperse more quickly.
|

Acute radiation Syndrome | Consists of three levels of effects: Hernatopoletic (blood cells, most sensitive); Gastrointestinal (GI cells, very sensitive); and Central Nervous System (brain/muscle cells, insensitive). The initial signs and symptoms are nausea, vomiting, fatigue, and loss of appetite. Below about 200 rems, these symptoms may be the only indication of radiation exposure.
|
alpha particle (a)
|
The alpha particle has a very short range in air and a very low ability to penetrate other materials, but it has a strong ability to ionize materials. Alpha particles are unable to penetrate even the thin layer of dead cells of human skin and consequently are not an external radiation hazard. Alpha-emitting nuclides inside the body as a result of inhalation or ingestion are a considerable internal radiation hazard.
|
beta particles (b)

You only need this if you are eating contaminated food and drinking contaminated fluids. If you hear of a nuclear detonation, leave the area and don't eat anything or drink anything except from sealed containers until you have decontaminated yourself and are far away from the area.
These things have been sold for use after a major nuclear bomb attack where there have been multiple nuclear bombs and there is no where to go and you have to eat what is there with you in the contaminated area. For what we are facing the best advice is leave the area, decontaminate yourself and refrain from eating until you are decontaminated.
