ADDITIONAL SECURITY There are many additional security measures the ship's store officer may follow, if necessary. The use of car seals is recommended but not mandatory. Using these seals may alert the ship's store officer of unauthorized entry. These numbered car seals are available from servmart and should be placed on external locks after working hours. These car seals are issued by the ship's store officer or a designated assistant to the custodian of the space. They are logged in the Car Seal Log and the number is checked in the log before removing any installed car seal. The ship's store officer may also have roll-up grills or scissor-type gates installed outside of retail stores. An intrusion alarm system may be installed to protect retail stores or storerooms. The alarm should be connected so it will sound off in an area that is manned 24 hours.
