ABSTRACT
Accidents with the risk of exposure to hazardous nuclear, biological, or chemical materials are rare. Most emergency rooms are not familiar with the management of contaminated patients after this kind of incident. There are also ambiguous cases concerning the contamination status of the patient. The medical attendance should be performed carefully and under special security arrangements until a hazard for third persons can be excluded. The security arrangements should protect both (medical) personnel and third persons. Early medical treatment combined with decontamination should be the aim. Based on the case of a contaminated patient who was brought to our emergency department after an explosion of a fog grenade with red phosphorus, we discuss our management concept and the current literature.
