What To Do In The Event of A Spill

What should you do in event of an Anhydrous ammonia or other hazardous material spill?

  • Go indoors and stay there. There is enough air to last at least three hours, which is ample time for emergency teams to respond to the spill.
  • Close all outside doors and every door inside the building.
  • Close all windows.
  • Do not use the bathroom vents or kitchen vents.
  • Set the thermostats so air conditioners, furnaces and hot water tanks will not come on.
  • Do not use fireplaces. Close all dampers.
  • Do not operate clothes dryers.
  • Shelter in an inside room away from doors and windows if possible.
  • Reduce or avoid smoking because it contaminates the air.
  • Do not leave building until told to do so.
  • Stay tuned to local television or radio for more information.
  • Do not use the telephone. It may tie up the phone lines.
