Chemical Threat


Chemical release, whether diliberate or accidental, can occur at facilities or along transportation routes and can cause direct injuries and death while also contaminating air, water, and soils.


Chemical incidents are characterized by the rapid onset of medical symptoms:

  • Watery eyes
  • Twitching
  • Choking
  • Difficulty breathing
  • Loss of coordination



In addition, many sick or dead birds, fish, or small animals may also indicate that a hazardous chemical has been released into the environment.

Have an Emergency Supply Kit and Household Disaster Plan in place.
