Exposure to Mustard Gas or Lewisite
Mustard gas is a common term that may refer to two forms of mustard agents: sulphur mustard (Yperite) or nitrogen mustard. Lewisite, an organic compound containing arsenic, is another mustard agent. The VA may grant service connection for certain diseases or disabilities as the result of full-body exposure to mustard gas or Lewisite during military service.
Disabilities or diseases for which service connection may be granted by presumption due to mustard gas or Lewisite exposure are in 38 CFR 3.316(a).
The VA will request and review pertinent service records for chemical exposure.
