5.18 DEVELOPMENT FOR EXPOSURE TO MUSTARD GAS AND LEWISITE
a. General. 38 CFR 3.316 authorizes service connection for veterans who underwent any full-body exposure to mustard gas or lewisite during military service. Service connection may be granted for the following conditions: chronic conjunctivitis, keratitis, corneal opacities, scar formation, nasopharyngeal cancer, lung cancer (except mesothelioma), or squamous cell carcinoma of the skin based on full-body exposure to nitrogen or sulfur mustard during active military service. Service connection may also be granted for a chronic form of laryngitis, bronchitis, emphysema, asthma, or chronic obstructive pulmonary disease based on full-body exposure to nitrogen or sulfur mustard or lewisite during active military service, and acute nonlymphocytic leukemia based on exposure to nitrogen mustard during active military service. Included are veterans:
(1) Exposed during field or chamber testing;
(2) Exposed under battlefield conditions in World War I;
(3) Present at the German air raid on the harbor of Bari, Italy, in World War II;
(4) Engaged in manufacturing and handling vesicant (blistering) agents during their military service.
(1) Development for evidence of full-body exposure to mustard gas or lewisite is necessary only if the
veteran claims exposure and has a mustard gas induced condition.
(2) Compensation claims based on exposure under battlefield conditions during WWI or other types of exposure, may show evidence in service medical records of the acute effects of mustard gas or lewisite exposure. Delayed effects of exposure may appear even though no acute effects were noted in service. It is also possible that the veteran may have been exposed to nonservice-related causative conditions or events.
c. Chemical Exposure Database. The Defense Manpower Data Center (DMDC) maintains a database containing information on Army and Navy persons who may have been exposed during World War II to mustard gas and lewisite during testing programs, production, storage or transportation.
