The K941 CATS contains 24 glass bottles, each containing 3 1/2 ounces of mustard (H and HS) or distilled mustard (HD) for a total of 84 ounces (2.48 liters) per set.
Bottles are round and have a small screw top. Heat resistant paint on the bottles indicates “H,” “HS,” “HD,” or "TOXIC GAS SET, M1.” Four bottles are packed in a one-half inch layer of sawdust within a sealed metal can. The cans are pressure sealed, 6 1/4 inches high, and have a sardine-type key on the bottom. Six of these metal cans are fitted into a steel shipping cylinder that is 6 5/8 inches in diameter, approximately 38 inches long, and 0.145 inch thick. The open end of this container is closed by a flanged end cover which is secured by eight bolts tightened over a 1/8 inch thick lead gasket.
In former WWII training areas, K941 shipping containers (also called PIGS) or loose K941 bottles are frequently found buried. Loose bottles should be handled carefully by field personnel during recovery using appropriate protective measures as the plastic/bakelite tops on these bottles are prone to leak.
