Agent Identification

  • Phosgene is colorless, fuming liquid below 47°F (8.2°C) and a colorless, nonflammable gas above 47°F with a suffocating odor like new mown hay. The odor threshold for phosgene is significantly higher than current inhalation exposure limits. Thus, odor provides insufficient warning of hazardous concentrations.
  • Responders should obtain assistance in identifying the chemical(s) from container shapes, placards, labels, shipping papers, and analytical tests. General information on these identification technicques is located in Emergency Response Guidebook.
  • A comprehensive source for the selection of chemical identification equipment is the Guide for the Selection of Chemical Detection Equipment for Emergency First Responders, Guide 100-06, January 2007, 3rd Edition published by the Department of Homeland Security to assist with this process.
