Dry-land drowning

Inhalation death occurs within 10 minutes, primarily a result of dry land drowning in which the lungs and throat fill with mucus, blood, and dead tissue, causing asphyxiation. Two milliliters of pure liquid lewisite absorbed by a 150-pound adult by any means would likely be fatal. Those who survive exposure may continue to show symptoms including pulmonary edema, neural disorders, subnormal body temperature, low blood pressure, and permanent damage to the endocrine system for an indefinite period.1... 

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.

Choking agents cause injury chiefly in the respiratory tract—that is, in the nose, throat, and, particularly, the lungs. In extreme cases membranes swell, the lungs become filled with liquid, and death results from lack of oxygen thus, these agents choke an unprotected man. Fatalities of this type are referred to as dry-land drownings. ...
