Summary: All attempts should be made to determine the identity of the hazardous material before the Unidentified Chemical guideline is used. Responders should obtain assistance in identifying the chemical(s) from container shapes, placards, labels, shipping papers, and analytical tests. General information on these identification techniques is located in Managing Hazardous Materials Incidents Volumes I and II. The Unidentified Chemical protocol provides basic victim management recommendations but the techniques for a specific chemical could provide information which would allow more effective patient treatment.
