Handling Suspicious Mail

In most cases, when discussing suspicious mail, it is mail that may contain a bomb, or a chemical, biological, radioactive or nuclear substance. It is good practice to screen mail you have received for unusual features.

You know what kind of mail and packages you usually get. Look for things that are out of the ordinary. Something may be suspicious if several of these features are present:

• There is too much postage using many low-value stamps.
• The return address is missing, foreign or indecipherable.
• The name, title or address is not correct or not spelled correctly. They may display distorted handwriting, or the name and address may be made with homemade labels or cut-and-paste letters.
• There is too much wrap, binding, tape, or tying material.
• You can feel wiring, aluminum foil or powder inside or protruding from the package.
• The letter or package feels too heavy. They may have an irregular shape with soft spots or bulges.
• The letter or package is dirty, oil- or grease-stained or leaking.
• There is a funny smell or noise or a sloshing sound.
• Cancellation or postmarks may indicate a different location than the return address or that the item was mailed from a foreign country.
• Letter bombs may feel rigid or appear uneven or lopsided.
• Bombs in parcels may be addressed to specific individuals or just their business title only (e.g., President), 
• Has restrictive notes such as "Personal", "Private", "To be opened only by" or notes such as "Fragile – Handle with Care", "Do not X-ray", or "Rush – Do not delay".  

Adapted from the Public Health Agency of Canada "What to do about Suspicious Letters or Packages" (2004), Government of Canada Get Prepared "Suspicious Packages" (2018), and the Canada Post's "What to do if you get a suspicious letter or parcel" (no date).

There is generally no need to be worried about the following:

• Mail and packages you receive from people you know.
• Mail and packages you receive from businesses you know.
• Items you have ordered from stores, such as books, food, or clothing.

If you are suspicious that a letter or package may contain a bomb, you may refuse to accept it.

If it is already on your premises:

• DO NOT SHAKE OR OPEN IT.
• Isolate it.
• Evacuate all persons from the area immediately.
• Do not put the item in water or a confined space, such as a desk drawer or filing cabinet.
• Follow your workplace procedure, or call for police assistance. 
• Wait in a safe location. 

If you are suspicious that a letter or package may contain a harmful chemical or biological substance, you may refuse to accept it.

• Remain calm.
• Do not shake or open the letter or package.
• Isolate the area where the package is.
• Notify your supervisor.
• Cover the letter or package with a plastic sheet or raincoat, or if none is available, leave the package where it is.
• Evacuate everyone out of the room and close all doors and windows. If there is a chance the substance is airborne, turn off the ventilation system so the substance does not circulate beyond the immediate area. 
• Follow your workplace procedure, or call for police assistance. 
• Wait in a safe place (another area) until the emergency responders arrive.

The contents of a letter or package may cause concern if:

• You see powder or a liquid.
• It contains a threatening note.
• It contains an object that you did not expect to receive or cannot identify.

If you touched a letter or package that possibly contains a harmful substance or got some on your clothes:

• Remain calm.
• Leave the letter or package where it is.
• Wash your hands well.
• Remove any clothing that has powder or liquid on it and seal it in a plastic bag.
• Evacuate everyone out of the room and close the door.
• Rewash your hands or shower with soap and water.
• Follow your workplace procedure, or call for police assistance. 
• Wait in a safe place (another area) until the emergency responders arrive.

The police, other emergency workers, and public health authorities will give you advice about what to do next.
