                                          TABUN

           SECTION II   (continued)

              Appearance and Odor:  Colorless to brown liquid; faint fruity odor (U.S.
                                    Army 1975, p.3-2)


           SECTION III - HEALTH HAZARD DATA

              OSHA PEL: Not Found

              ACGIH TLY: Not Found

 }            *IDLH: Not Found

              Other Limits Recommended:   Not Found

              Routes of Entry: Inhalation: Yes (U.S. Army 1975, p. 3-2)
                               Skin: Yes (U.S. Army 1975, p. 3-2)
                               Ingestion: Yes (U.S. Army 1975, p. 3-2)

              Health Hazards (Acute, Delayed, and Chronic): This material is toxic by
              inhalation and by absorption through skin and eyes. The lethal dose for
              humans may be as low as 0.01 mg/kg (Merck 1983, p. 1297).   Tabun is a nerve
              agent; it acts as a cholinesterase inhibitor. The median lethal dosage
              (respiratory) is 400 mg-minute/m3 for humans; the median incapacitating
     )        dosage is 300 mg-minute/m~  Respiratory lethal dosages kill in 1 to 10
              minutes; liquid in the eye kills nearly as rapidly. Skin absorption great
              enough to cause death may occur in 1 to 2 minutes, but may be delayed for I
              to 2 hours (U.S. Army 1975, p. 3-3).

              Medical Conditions Generally Aggravated by Exposure: Not Found

           SECTION IV - FIRE AND EXPLOSION HAZARD DATA

              Flash Point (Method Used):  1720F (Sax 1984, p. 1335)
              Flammable Limits:
                  LEL: Not Found
                  UEL: Not Found

              Extinguishing Methods: (Non-Specific - Poison A, Liquid)    Extinguish
              with alcohol foam, carbon dioxide, or dry chemical (Student 1981, p. 56)

              Special Fire Fighting Procedures: Complete protection required; have
              available decontaminants (bleach, alkali) and atropine (U~. Army 1975, p.
              3-2). Bleaching powder (chlorinated line) destroys Ta bun but gives rise to
              cyanogen chloride (Merck 1983, p. 1297).

              Unusual Fire and Explosion Hazards:  Extremely poisonous (Merck 1983, p.
              1297). (Non-Specific - Poison A, Liquid)     Keep away from sparks, flames,
              and sources of ignition. Keep out of water sources and sewers (Student
              1981, p. 56).
