Airborne Release

An evacuation during an airborne release of toxic chemicals is not always advisable or the safest measure protection.  Preparations for sheltering yourself and others in place are outlined below.  Preferred areas for protective sheltering would be interior hallways, rooms without windows or exterior doors, enclosed stairways and rooms on the side of the building away from where the hazard is approaching. Doors, windows and other potential air leaks should be sealed up to prevent toxic fumes from entering.


Recommended In Place Shelter Instructions

  • Once notified by your Building Supervisor/Building Emergency Officer or designate, close all doors to the outside and close and lock all windows.
  • If possible, turn off fume hoods, range hoods, air handlers and all air-conditioners and switch inlets to the "closed" position. Seal any gaps around window type air-conditioners.
  • Seal off all vents, grills or other openings to the outside to the extent possible.
  • Breathing through a wet cloth or handkerchief held to your nose and mouth may help reduce your exposure to some airborne dusts and vapors.
  • Minimize the use of elevators in buildings. These tend to "pump" outdoor air in and out of a building as they travel up and down.
  • Tune to the Emergency Broadcast Station on your radio or television for further information and guidance.
  • Do not evacuate your building unless told to do so by the University Police..
