TEST TUBE REPUBLIC: Chemical Weapons Tests in Panama and U.S. Responsibility


Annex A: Chemical Weapons Activities of United States in Panama, by Site

San Jose Island
Site of extensive tests of chemical munitions from 1944 through 1947. Target areas likely to contain hundreds or thousands of unexploded munitions. See section IV-B.

Cerro Tigre
Storage area for bulk chemical agent beginning in 1930s and through at least 1956, in both open areas and igloo-type magazines.

Chiva Chiva
A knoll on the "Chiva Chiva trail" used as a test and disposal site for chemical munitions in 1950s.

Curundu
Site for storage and tests of toxic materials at "demonstration area" from 1952-1956. Reportedly site for Tropic Test Center's analysis and decontamination of VX nerve agent in 1960s tests.

Fort Clayton
Site of mustard gas tests on soldiers in 1941. Included 8 ft. x 12 ft. magazine for storage of chemical munitions in 1941. Also the headquarters for the Chemical Corps Tropical Test Team in 1956.

Chemical Agents Stored or Tested in Panama

Persistent agents have lethal effects for hours or days after their detonation, while nonpersistent agents act more rapidly, and in the air dissipate within minutes.

Agent Kind Form Munitions Lethal dose Symptoms (inhaled) Comments
VX nerve agent, persistent oily liquid or aerosol mines, rockets, projectiles 10 mg (on skin) vision blurs and dims; difficulty breathing lethal: drooling, vomiting, coma, convulsions, asphyxia Sparingly soluble in water; acts on body similarly to many insecticides
Sarin (GB) nerve agent, nonpersistent liquid or vapor 105 mm and 155 mm projectiles 70 mg vision blurs and dims; difficulty breathing lethal: drooling, vomiting, coma, convulsions, asphyxia Soluble in water; acts on body similarly to many insecticides
Mustard (H) blister agent, persistent vapor or liquid 4.2" mortars; 105 mm and 155 mm projectiles; Livens projectors; bombs. Stored in spray tanks, one-ton containers 1000 mg eyes: inflammation, aversion to light, blindnessskin: skin blisterslethal: resembles CG in effect on breathing In seawater forms a gel that preserves mustard agent inside; highly corrosive
Phosgene (CG) choking agent, nonpersistent gas bombs; 7.2" rockets 3200 mg lethal: coughing, frothing at mouth, asphyxia, pneumonia Caused 80% of chemical fatalities in World War I
Cyanogen chloride (CK) blood agent gas 4.2" mortars; bombs 2500 mg irritates eyes and nasal passageslethal: paralyzes nervous system Affects oxygen exchange in red blood cells
Hydrogen cyanide (AC) blood agent gas bombs (from 100 lb. to 2,000 lb.) 5000 mg lethal: giddiness, convulsions, asphyxia Affects oxygen exchange in red blood cells
