Alternate Title: CDC: Mustard Gas
This webpage is maintained by the Centers for Disease Control and Prevention (CDC). The webpage provides information and resources on sulfur mustard (mustard gas). "[...] Sulfur mustard is a type of chemical warfare agent. These kinds of agents are called vesicants or blistering agents, because they cause blistering of the skin and mucous membranes on contact. [...] Sulfur mustard is also known as "mustard gas or mustard agent," or by the military designations H, HD, and HT. [...] Sulfur mustard sometimes smells like garlic, onions, or mustard and sometimes has no odor. It can be a vapor (the gaseous form of a liquid), an oily-textured liquid, or a solid. [...] Sulfur mustard can be clear to yellow or brown when it is in liquid or solid form."
