or DS2. Decontaminate liquid agent on the skin with the M258A1, M258, or M291 skin decontaminating kit. Decontaminate individual equipment with the M280 individual equipment decontamination kit. 

Depends upon the amount of contamination by liquid, the munition used, the nature of the terrain and the soil, and the weather conditions, ffeavily splashed liquid persists 1-2 days or more in concentrations that produce casualties of military significance under average weather conditions, and a week to months under very cold conditions. Q on soil remains vesicant for about 2 weeks. Persistency in running water is only a few days, while persistency in stagnant water can be several months. 

Delayed-action casualty agent. Not authorized for military use. 

HT is a mixture of 60% HD and 40% agent T. It is expected that the effects of HT would encompass of both HD and T. Both HD and T are alkylating agents. T is a sulfur and chlorine compound similar in structure to HD. HT has a strong blistering effect, has a longer duration of effectiveness, is more stable, and has a lower freezing point than HD. Its low volatility makes effective vapor concentrations in the field difficult to obtain. Properties are essentially the same as those of HD.

HT Sulfur Mustard (60%) and O-Mustard (40%) Standard Mixture C03-A005... 

Sulfur mustards (designated H [mustard], HD [distilled mustard], and HT [HD and T mixture]) do not present acute lethal hazards. Their principal effect is severe blistering of the skin and mucous membranes. Epidemiological evidence indicates a causal relationship between exposure to mustard agent at high concentrations and the development of chronic nonreversible respiratory disorders, such as chronic bronchitis and asthma, and ocular diseases, such as delayed recurrent keratitis and prolonged, intractable conjunctivitis (IOM, 1993). Sulfur mustard has been classified as a known human carcinogen based on evidence of in-... 

Agent HT is generally a mixture of 60% HD and 40% bis(2-chloroethylthioethyl)ether (T), although this ratio may vary. Agent HL is a mixture of sulfur mustard (HD) and lewisite (L) that was developed for cold weather or high-altitude use due to its lower freezing point. Sesqui mustard (Q) is l,2-bis(2-chloroethylthio) ethane and is considered a more potent vesicant than HD but its very low vapor pressure limits its effectiveness as a warfare agent,... 

Sulfur mustard is a component of the H-series blister agents including undistilled sulfur mustard (H sulfur mustard with 20-30% impurities, also known as Levinstein mustard), distilled sulfur mustard (HD or HS 96% pure), a mustard-lewisite mixture (HL), and HD/agent T mixture (HT a mixture of HD and nonvolatile agent T), and an HD/agent Q mixture (HQ a mixture of HD and nonvolatile Agent Q (Agent Q is also known as sesquimustard).

HT A mixture of 60% HD and 40% T. T is a sulfur oxygen and chlorine compound similar to HD and is a clear yellowish liquid with a slight garlic or mustard like odor. Insoluble in water.
