Nitrogen Mustard - HN

Persistency Depends on munitions used and the weather. Somewhat shorter than that of HD, heavily splashed liquid of which persists 1-2 days under average weather conditions, and a week or more under very cold conditions. 

Boiling point 194°C (calculated) decomposes. At atmospheric pressure HN-1 decomposes below boiling point. 

Flash point No immediate danger of fire or explosion. 

Decomposition temperature Decomposes before boiling point is reached. 

Liquid density Solid density Vapor pressure

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). 

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. 

The lARC has classified nitrogen mustard HN-2 as probably carcinogenic to humans based on evidence that it causes leukemia in humans and cancers of the lung, liver, uterus, and large intestine in animals. ...

The bulk of what is known about human skin injury from SM has been gathered from victims of the mihtary use of the compoimd (Balali-Mood and Hefazi, 2006 Hefazi et al., 2006 Requena et al, 1988). Nevertheless, there are several reports where the cutaneous vesicating effects of SM were studied experimentally in human subjects (Papirmeister et al, 1991a, b Dacre and Goldman, 1996). In one comparative study (Daily et al, 1994) 12 volunteers had forearm vapor cup applications of SM, trifunctional nitrogen mustard (HNS), and lewisite. The conclusions were...
