New Hazardous Materials Management Instruction

The Postal ServiceTM is committed to providing a safe workplace for its employees and providing for the safety of the general public and transportation infrastructure through the responsible management of hazardous materials and nonmailable items in the mail.

To help accomplish this, Network Operations Management recently issued Management Instruction (MI) DM-601-05-1, Hazardous Materials Acceptance and Handling.

This MI consolidates previously issued Postal Service policy and procedures for the acceptance, handling, processing, and transportation of mail containing hazardous materials throughout the Postal Service. The MI also identifies policy and procedures for the handling of nonmailable items found in the mail after acceptance.

The policies and guidelines in this MI apply to all employees at all locations where mail is accepted, handled, processed, and delivered. These procedures may not be altered for local implementation. This MI does not include policy and procedures for hazardous materials releases or suspicious and unknown powders or substances.

The MI will be available on the Postal ServiceTM PolicyNet Web site:
