252 Guidelines for Dispatch Personnel

Postal Service dispatch personnel handle hazardous, restricted, or perishable materials according to general guidelines with specific procedures based on the class and content of the mailpiece and as outlined in the POM:

  1. Prevent Damage and Hazards: Hazardous materials, restricted matter, and perishable matter must be properly handled to avoid damage or danger.
  2. Verify Air Transport Readiness: Only properly packaged, marked, and labeled mailpieces are tendered to the air carrier. Dispatch personnel should ensure:
    1. Packaging Integrity: Packaging is strong and securely closed, with no visual evidence of leakage or damage.
    2. Proper Markings and Labels: All required markings and labels are on the outer packaging.
    3. Attach Shipping Paper: A properly completed shipping paper is attached to the outside of the mailpiece and to the dispatch document, with information detailed in 711.3.
    4. Handling Nonmailable Material: If a mailpiece is suspected to contain nonmailable material, it is removed from the mailstream and handled per POM 139.117-118.
