H-series agents - a series of persistent blister agents, that include distilled mustard (HD) and the nitrogen mustards (HN-1, HN-2, and HN-3). 

Rapid hydrolysis aids in lowering the duration of effectiveness of toxic chemical agents. For example, in the presence of water or water vapor, lewisite (L) rapidly hydrolyzes. Therefore, it has a shorter duration of effectiveness than distilled mustard (HD).

Blister agents such as distilled mustard (HD) and nitrogen mustard (HN) have a slow rate of action and might be persistence for three days to one week in warm weather and for some weeks in cold weather, while lewisite (L) and mustard/lewisite (HL) have a quick rate of action and would be persistent for one to three days during summer and for weeks during winter. Route of entry for these blister agents would be nearly the same eyes, lungs, and skin for vapor or aerosol, but for liquid, the points of entry would be the eyes and skin for HD and HN and eyes, skin, and mouth for L and HL.

Mustard-Lewisite mixture is a liquid mixture of distilled mustard (HD) and Lewisite. Due to its low freezing point, the mixture remains a liquid in cold weather and at high altitudes its low freezing point make it better for ground dispersal and aerial spraying. The mixture with the lowest freezing point consists of 63 percent Lewisite and 37 percent mustard. 

Chemical Agent HD Distilled mustard (HD), or bis (2-chloroethyl) sulfide, (CAS 505-60-2) is mustard (H) that has been purified by washing and vacuum distillation to reduce sulfur impurities Agent HD is a blister agent.

The only agent in this category is distilled mustard (HD). Two other mustard agents (Q and T) developed in the past were dropped from production because they were redundant or were superseded by newer agents. Mustards got their name from their unique smell that resembles burning garlic. Personnel exposed to mustards should be decontaminated immediately and given medical attention. 

In pure liquid form, lewisite causes blindness, immediate destruction of lung tissue, and systemic blood poisoning. It is absorbed through the skin like distilled mustard, but is much more toxic to the skin. Skin exposure results in immediate pain a rash forms within 30 minutes. Severe chemical burns are possible. Blistering of the skin takes up to 13 hours to develop. Lewisite does not dissolve in human sweat. It commingles with sweat, then flows to tender skin areas such as the inner arm, buttocks, and crotch. 

After skin is exposed to HN-2 an epidermal rash develops within approximately an hour. If initial exposure is very low, a rash may not develop. As with HN-1, HN-2 exposure is cumulative. If a person receives multiple low-level exposures, a rash will eventually appear. Blistering will begin about 12 hours after the onset of the skin rash. As with other blister agents, great irritation results when HN-2 vapor or liquid mixes with sweat and flows to tender skin areas (e.g., armpits, buttocks, crotch). Pulmonary effects from exposure to HN-2 are not as severe as for distilled mustard. Dry-land drowning syndrome can occur as the lungs flood with mucus, dead tissue, and blood. The victim dies from a combination of asphyxiation and heart failure. 

Since HN-3 is over 7 times heavier than air, it typically concentrates within the substructures of building and on low-lying terrain. HN-3 is 2 to 3 times more persistent than distilled mustard.1 As a form of calibration, a downwind evacuation from a 55-gallon spill of this agent should be a minimum of 2.1 miles.2 See Table 3.3 for a summary of the symptoms of exposure and potential medical treatment options. 

Agent T is out of production. It was created in the mid 1930s and used alone in warm climates or as a distilled mustard thickener. It is obsolete as a pure agent, and semi-obsolete as a mixer.

Acoustic wave sensors are also used to detect nerve and blister agents. The surface acoustic wave chemical agent detector (SAW Mini-CAD) is a commercially available, pocket-sized instrument that can monitor for trace levels of toxic vapors of sulfur-based mustard agents (e.g., distilled mustard) and G nerve agents (e.g., tabun, sarin, soman) with a high degree of specificity. Colorimetric tubes are the...

The blister agents are labeled H, HD, and HT. The active ingredient, mustard, in all these blister agents is bis(2-chloroethyl) sulfide, (C1CH2CH2)2S. HD, called distilled mustard, is nominally pure mustard. H, often called Levenstein mustard, is approximately 70 percent mustard and 30 per cent impurities, which tend to be poly sulfides such as (ClCH2CH2)2Sn, where n > 2. HT contains 67 per cent mustard and 22 percent T, (C1CH2CH2SCH2CH2)20, and minor components.

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-...
