First In Still Here (FISH)is an informal industry term humorously describing inventory that has not moved for a long time—often applicable to obsolete or slow-moving items, such as outdated electronics. The CLT “Inventory Control” discussion of stock rotation and turnover stresses avoiding “FISH” inventory, which ties up capital and warehouse space. Electronic products rapidly lose value or technological relevance, so identifying and clearing stagnant stock is vital. CLT encourages usingABC analysisand continuous review to highlight FISH items for markdown, return, or disposal. While not a formal control method like FIFO or JIT, understanding FISH alerts managers to inefficiencies that hinder inventory flow and profitability.

In CLT equipment modules, atranstainer(gantry container handling crane, sometimes rail-mounted) is used in port terminals to lift containers off vessels and place them on trucks or rail cars. While straddle carriers and reach stackers also move containers within yards, the transtainer/ship-to-shore cranes are core to vessel-to-landside transfer.

Within CLT “Order Processing” terminology, alinerefers to a single Stock Keeping Unit (SKU) on an order, regardless of the quantity required. When multiple quantities of the same SKU are requested, it is consideredone line. An order, on the other hand, may contain multiple lines. Understanding this terminology helps warehouse associates differentiate between “line count” and “item count,” which are critical for performance tracking and system accuracy. For example, an order with three SKUs and five total pieces equals three lines but five items. Recognizing these distinctions supports accurate order metrics, picking efficiency reports, and helps align with performance KPIs defined in the CLT competency framework for warehouse documentation and data management.

Astacking frameis described in CLT training under “Storage Equipment” as a modular, interlocking system designed to support and stabilize loads stacked vertically. It prevents crushing or deformation of goods by transferring weight through the frame rather than the product itself. Stacking frames are especially useful for irregularly shaped items or products that cannot safely bear additional weight. They also allow flexible layout adjustments because they can be easily disassembled or moved as inventory needs change. In contrast, pallet racks are fixed systems, and bins or standard racks do not inherently prevent compression damage. The CLT program highlights stacking frames as essential for space optimization and product protection, supporting safe vertical storage without permanent rack infrastructure.

TheMan-on-Board AS/RSrepresents the simplest automated retrieval system where an operator rides on the storage/retrieval machine to manually select or place loads. CLT’s “Automated Systems” section identifies this as a semi-automated system that combines human control with mechanical assistance for efficiency and precision. It contrasts with fully automated AS/RS where retrieval is entirely computer-controlled. The Man-on-Board system is ideal for large or variable-sized items requiring human judgment. CLT emphasizes that even with operator presence, safety protocols—such as harnessing, emergency stops, and restricted access—must be followed. This system provides a transitional solution between manual storage and full automation, improving throughput while maintaining operator involvement.

ThePackaging and Shipmentcompetency in CLT highlights that certain materials—particularly liquids, chemicals, and powdered or granulated bulk goods—require sealed containment to prevent leakage, contamination, or evaporation.Drums and barrels(metal, plastic, or fiber) meet these requirements because they provide durable, sealed storage and easy handling via pallet jacks or drum clamps. Corrugated containers lack liquid containment strength, and wire mesh containers are ventilated for solid goods. Using proper packaging ensures regulatory compliance for hazardous or sensitive materials and preserves product quality during transport and storage.

Within CLT’s dispatch and delivery verification section, theDelivery Receiptserves as the official acknowledgment that goods have been received at their destination in the condition and quantity stated. It is typically prepared by the carrier and signed by the consignee after inspection and verification. The Delivery Receipt completes the transportation transaction, providing traceable confirmation for billing and audit. TheAirway Billapplies only to air freight; theCarrier Freight Billis the carrier’s invoice; and theBill of Ladingfunctions as the shipment contract. Therefore, the Delivery Receipt specifically fulfills the consignee’s proof-of-delivery obligation.

Thehandheld bar code scanneris the standard device used in cycle counting and verification processes. CLT “Inventory Control” identifies cycle counting as a periodic counting method used to maintain continuous inventory accuracy. Bar code scanners allow operators to quickly identify and record item numbers, quantities, and locations by scanning Universal Product Code (UPC) or SKU labels. Data is transmitted to the WMS for reconciliation against system records. This method reduces human error, minimizes disruption, and provides real-time updates compared to traditional physical inventory counts. CLT highlights the efficiency, precision, and auditability of barcode-assisted counts as a best practice for modern warehouse operations.

A product with acritical shelf lifedeteriorates over time and must be used or shipped before expiration. CLT “Product Storage” training categorizes perishables such as bread, milk, and pharmaceuticals as shelf-life-sensitive products requiring rotation systems likeFIFO (First In, First Out).Radioactive materials, while hazardous, are measured by half-life rather than spoilage or usability date and are regulated differently under hazardous-materials standards. Therefore, they are not considered shelf-life-critical from an inventory standpoint. CLT emphasizes proper labeling, temperature control, and rotation methods for shelf-life goods to ensure safety, quality, and compliance with regulatory requirements such as FDA or USDA guidelines.

Areach stackeris a mobile, heavy-duty container-handling vehicle capable of lifting containers and stacking or transferring them to/from other vehicles or stacks. It’s flexible and maneuverable for yard operations. Grappler lifts, hand trucks, and transtainers have different roles (fixed cranes, small load movement, large gantry cranes).
