A potentially dangerous situation exists whenever hazardous materials, restricted matter, or perishable matter is being moved from one place to another. Careless handling can result in serious injury to the general public and Postal Service personnel, damage to other mail and Postal Service equipment, and delays in processing and delivery of mail.
The Postal Operations Manual (POM) provides additional instructions for handling hazardous materials in the mail.
