MUSTARD AGENTS

What is MUSTARD? 	Mustard agents are also known as blister agents. 
			Common names include sulfur mustard, lewisite, 
			nitrogen mustard and mustard lewisite. Sulfur 
			mustards are yellow to brown oily liquids with a 
			slight garlic, onion or mustard odor. They may 
			have no odor. Vapors can reach hazardous levels 
			during warm weather. Mustard agents are 
			considered chemical warfare agents.

Signs and Symptoms:	Depends on route and amount of exposure. Signs 
			and symptoms include skin redness, itching and 
			blistering, watering and swollen eyes, irritated 
			nose and throat, possible toxic infection (sepsis), 
			shortness of breath, and nausea and vomiting. 
			Inhalation damages the lungs and airway and may 
			cause death. Contact can cause permanent 
			damage.		

Exposure: 		Primary route is by either inhalation or absorption 
			through the skin or eyes.  

What can you do?	Emergency response leaders may direct people to 
			evacuate or ”shelter in place.” If you are in an area 
			where mustard was released, leave the area 
			immediately and get to higher ground. 

Treatment:		There is no specific treatment; therefore, it is best 
			to avoid it. Remove contaminated clothing 
			immediately and wash exposed skin/eyes. 
			Supportive hospital care is often necessary.

Diagnosis:	 	Based on known or suspected exposure.
