Sulfur Mustard Exposure Presenting to a Community Emergency Department

We report dermal exposure to a chemical warfare agent, sulfur mustard, in a 28-year-old commercial fisherman. Chemical warfare agents such as sulfur mustard are considered potential terrorist weapons, and suspected exposure requires notification of federal authorities. We address potential pitfalls when alerting authorities and methods to avoid such obstacles, and we describe the clinical management of sulfur mustard toxicity.
