Bomb threat

If you receive a bomb threat, it’s important to remain calm. Do not try to assess whether it’s a genuine threat or a hoax. Always assume it’s genuine. Even if the caller says it’s a joke, notify Security.

  • Be polite and courteous
  • Do not interrupt the caller and stay on the line
  • Try to get as much information as possible:
    • Location of the bomb
    • When it will explode
    • Why they placed the bomb in the building
    • The type of bomb
  • Note the number they are calling from
  • Note what you can about the caller:
    • Sex
    • Accent
    • How they speak
    • Background noise
    • And so on.
  • Call Security to report the situation
  • Print and fill out the bomb threat form (pdf)

If you receive a bomb threat by email, notify Security. Do not delete the message.

In the event of a bomb threat, all meetings and other activities must stop immediately.

Everyone in the building must return to their own workplace so an inspection can be carried out.

Special instructions for Building 26 (National Experimental Biology Centre)

  • Ask all staff who work in confinement zones to leave but do not create panic.
  • Close containers of infectious material and lock animals in their cages.
  • Leave the confinement area calmly following standard procedure.


When you enter a room:

  • Listen for unusual or suspicious noises.
  • Conduct a thorough visual inspection:
    • Look around the entire room at ground level
    • Look around the entire room at waist level
    • Look around the entire room at eye level
    • Look at the ceiling to check for:
      • Ceiling tiles out of place
      • Light fixtures out of place
      • A/C or heating vents out of place
      • Finger marks
      • Damage
  • Once you’ve completed the visual inspection, inspect the room more thoroughly.

Work calmly and methodically so you don’t skip any parts of the room.

Calling 911
