Why Use Security Seals?

Security seals are applied to provide proof of entry. There are many types and degrees of security seals, but they are of little use if not used as an integral part of the procedures and systems established by users to apply and control security seals.

This information is intended to provide assistance to seal users, assisting them in establishing the appropriate control procedures and systems, in order to use security seals to prevent theft and robbery.

The process necessary for the proper management of security seals is shown below:

Ordering Security Seals

Procedure to request security seals

  1. Ordering security seals, should always be the responsibility of one designated person in a company.
  2. All orders for security seals should come from on centralized location in the company.
  3. Seal manufacturers should ship security seals to one specific location in the company.
  4. Security seals should be laser marked with a marking and number series unique to the company that uses the seals.
  5. Utilizing color coding or location coding is an ideal method to identify different distribution centers or terminals of companies.

Storing Security Seals

Security seals should always be kept in a secure area where only authorized personnel will have access. This will prevent fraudulent use of security seals. A log book of “seal release” must be kept.

Maintain one log book for outbound seal recording and a separate log book for inbound seal recording. The outbound security seal log book should contain the following information:

  1. Date and time of seal application.
  2. Trailer or container number.
  3. Shipment destination.

  5. Driver identity.

If the driver is not an employee of the shipper, the application of the seal should be monitored by a representative of the shipper. The driver will print the seal marking and numbering in the bill of lading, and the shipper’s representative will sign off on the shipping document.

Application of the seals is important 

All seals must be applied according to the instruction of the manufacturer, and a designated employee must check the seal application. Select the most suitable security seal for the shipment, based on value, destination and other logistic factors.

The following procedures for application should be used:

  1. Seal all door openings on the trailer or container.
  2. Insert the seal strap through the locking hasp.
  3. Listen for the “click” when locking the seal.
  4. In order to insure a correct seal application, always check the seal application by pulling the part of the seal that was inserted into the locking mechanism.
