A.6 Supplemental Evacuation Guidelines for People with Disabilities

The following guidelines have been adopted by Purdue University to assist in planning for the evacuation of people with physical disabilities.

In All Emergencies, After an Evacuation has been Ordered:

  • Evacuate if possible.
  • DO NOT use elevators, unless authorized to do so by emergency services personnel.
  • If you have a Physical Disability and are Unable to Use Stairways:
  • Stay calm, and take steps to protect yourself.
  • If there is a working phone, call 911 and tell the police dispatcher where you are or where you will be moving to.
  • If you must move, we recommend the following:
  • Move to an enclosed exit stairway.
  • Request persons exiting by way of the stairway to notify the Fire Department of your location.
  • As soon as practical, move onto the stairway and await fire department personnel.  If the situation is life threatening, call 911 from campus telephone or 911 from a pay telephone.
  • Check on people with special needs during an evacuation.  A “buddy system”, where people with disabilities arrange for volunteers (co-workers/neighbors) to alert them and assist them in an emergency, is recommended.
  • Only attempt an emergency evacuation if you have had emergency assistance training or the person is in immediate danger and cannot wait for emergency services personnel.
  • ALWAYS ASK someone with a disability how you can help before attempting any emergency evacuation assistance.  Ask how he or she can best be assisted or moved, and whether there are any special considerations or items that need to come with the person.

7.1 Blindness or Visual Impairment

  • Provide verbal instructions to advise of the safest route or direction using simple directions, estimated distances, and directional terms.
  • DO NOT grasp a visually impaired person’s arm.  Ask if he or she would like to hold onto your arm as you exit, especially if there is debris or a crowd.
  • Give other verbal instructions or information (i.e. elevators cannot be used).

7.2 Deafness or Hearing Loss

  • Get the attention of a person with a hearing disability by touch and eye contact.  Clearly state the problem.  Gestures and pointing are helpful, but be prepared to write a brief statement if the person does not seem to understand.
  • Offer visual instructions to advise of safest route or direction by pointing toward exits or evacuation maps.

7.3 Mobility Impairment

  • It may be necessary to help clear the exit route of debris (if possible).
  • If people with mobility impairments cannot exit, they should move to a safer area, e.g.
    • most enclosed stairwells
    • an office with the door shut which is a good distance from the hazard (and away from falling debris in the case of earthquakes
  • Call 911 or notify police or fire personnel immediately about any people remaining in the building and their locations.
  • Police or fire personnel will decide whether people are safe where they are, and will evacuate them as necessary.  The Fire Department may determine that it is safe to override the rule against using elevators.
  • If people are in immediate danger and cannot be moved to a safer area to wait for assistance, it may be necessary to evacuate them using an evacuation chair or a carry technique.

Power Outages:

  • If an outage occurs during the day and people with disabilities choose to wait in the building for electricity to be restored, they can move near a window where there is natural light and access to a working telephone.  During regular business hours, Building Deputies should be notified so they can advise emergency personnel.
  • If people would like to leave and an evacuation has been ordered, or if the outage occurs at night, call 911 and request evacuation assistance.

The following guidelines are general and may not apply in every circumstance.

  • Occupants should be invited to volunteer ahead of time to assist people with disabilities in an emergency.  If a volunteer is not available, designate someone to assist who is willing to accept the responsibility.
  • Volunteers can obtain emergency evacuation information regarding lifting techniques from the Affirmative Action Office.
  • Two or more trained volunteers, if available, should conduct the evacuation.
  • Try to avoid evacuating people with disabilities in their wheelchairs.  This is standard practice to ensure the safety of people with disabilities and volunteers.  Wheelchairs will be evacuated later if possible.
  • ALWAYS ASK people with disabilities how you can help before attempting any emergency evacuation assistance.  Ask how they can best be assisted or moved, and if there are any special considerations or items that need to come with them.
  • Proper lifting techniques (e.g. bending the knees, keeping the back straight, holding the person close before lifting, and using leg muscles to lift) should be used to avoid injury to rescuer’s backs.
  • Certain lifts may need to be modified, depending on the disabilities of the people.

Prepare occupants in your building ahead of time for emergency evacuations.  Know your building occupants.  Train staff, faculty, and students to be aware of the needs of people with disabilities and to know how to offer assistance.  Hold evacuation drills in which occupants participate, and evaluate drills to identify areas that need improvement.  Plans must cover regular working hours, after hours, and weekends.  Everyone needs to take responsibility for preparing for emergencies.  People with disabilities should consider what they would do and whether they need to take additional steps to prepare.
