  • chemical weapon symptoms can present within

    minutes or hours

    symptoms of NERVE AGENTS

    blurred vision, uncontrolled twitching, convulsions, seizures, or respiratory distress.

    symptoms of CHOKING AGENTS

    respiratory distress, burning of the lungs and airways, choking, and coughing

    Biological weapons contain

    living organisms and are unpredictable and uncontrollable when released.

    Biological agents can be dispersed through

    food, and water supplies by using aerosols, liquid droplets, solid dispersion (powder) and by using creatures such as: fleas, ticks, or other insects to spread the agent

    a key indicators of exposure to biological weapons

    is the DELAYED onset of symptoms

    Biological: symptoms may appear within a

    few hours, or may develop over a period of days.

    First responders of a biological incident may

    unknowingly become carriers and spread the agent before symptoms appear.

    The FIRST VICTIM of smallpox may become:

    ill and unknowingly continue to work in place

    Aside from written and verbal threats, possible indicators of a biological attack include

    unusual numbers of sick or dying people or animals, and unusually high prevalence of respiratory involvement in diseases that typically cause a non-pulmonary syndrome, unexplained damage and ruin to crops and agricultural products, and abnormal swarms of insects.

    The most common examples of biological weapons include

    anthrax, ricin, smallpox, botulinum

    Anthrax

    is a naturally occurring bacterium. The primary routes of exposure to anthrax are SKIN and INHALATION.

    Anthrax: If exposure occurs through the SKIN symptoms include

    a rash and lesions that begin small but grow over a period of days.

    Anthrax: if exposure is INHALED symptoms are

    flu-like such as: respiratory distress, vomiting, and fever, occurs SEVERAL days after exposure.

    Inhalation of anthrax has a VERY HIGH MORALITY Rate while

    skin exposure has a HIGH SURVIVAL RATE

    Smallpox

    a contagious infectious disease that can be transmitted by prolonged face-to-face contact with an infected person, direct contact with infected bodily fluids, and direct contact with an infected objects (clothing)

    smallpox: after and INCUBATION period of

    7 to 17 days: symptoms such as: a pox-like rash, raised bumps, fever, muscle rigidity, shivering, malaise, headaches, and vomiting occur.

    Ricin

    HIGHLY TOXIC- poison found in SEEDS of the CASTOR BEAN PLANT. the primary routes of exposure to ricin are INGESTION and INHALATION. when ricin is INGESTED: symptoms begin a FEW HOURS; abdominal pain, vomiting and diarrhea

    ricin: within several days sufferers experience:

    dehydration, decreased urination, and decreased blood pressure.

    When a person INHALES RICIN:

    symptoms begin 18-24 hours after exposure and include fever, chest tightness, cough, nausea, and joint pain

    (Ricin) severe respiratory distress and death can occur in

    36-72 hours

    Botulinum (Botulism)

    is EXTREMELY TOXIC:

    weaponized forms of botulinum toxin can be introduced to the body through

    INGESTION, INHALATION, ABSORTION. symptoms; include difficulty seeing, speaking, and swallowing and having double vision, drooping eyelids, slurred speech, dry mouth, and muscle weakness. OCCUR WITHIN 12 to 80 HOURS OF EXPOSURE.

    Dirty Bombs also know as :

    radiation dispersal devices

    Dirt bombs are

    traditional bombs with radioactive materials loaded into the CASING. They are not considered nuclear weapons because they do not contain the same explosive power and their radiation is preloaded, whereas NUCLEAR weapons create radioactivity upon detonation.

    dirty bombs require both a

    casing and detonation mechanism

    people might say the bomb didn't blow anything up it just

    blew it apart

    radiation may not be readily detected by the senses, but

    bomb squad and hazmat teams, as well as health officials, have equipment to detect the amount of radiation in the area.
