How to Evaluate a Reusable Industrial Load-Securement System

Introduction: Choosing a Restraint Requires More Than Comparing Products

Distribution centers, warehouses, manufacturing facilities, and industrial operations depend on material-handling equipment to move products efficiently. Nesting racks, carts, and roll cages may carry everything from uniform cartons to long, flexible, cylindrical, or mixed cargo.

When products can shift or fall during handling, an appropriate containment method becomes an important part of the operating process.

Some facilities address these challenges with bungee cords, disposable strapping, adhesive tape, or other temporary restraints. Others may benefit from evaluating an engineered, reusable alternative.

However, reusability alone does not establish that a system is safe, compatible, durable, or cost-effective. A restraint that works well in one application may be unsuitable for another.

The selection process should begin with the actual hazard and consider the equipment, cargo, operating environment, and employee workflow.

EZAIZAI LLC and 2KSteel recommend a structured, application-specific evaluation before selecting a reusable industrial load-containment system.

1. Define the Load-Containment Problem

Before comparing products, determine what the existing process needs to accomplish.

Ask:

• What products are shifting, leaning, rolling, or moving toward an opening?
• Under what circumstances does the movement occur?
• Is the problem associated with a full rack, a partially loaded rack, or both?
• Which direction can the cargo move?
• What hazards could result from the movement?
• What does the current restraint accomplish, and where does it fall short?

The answers should identify a specific containment requirement rather than a general desire to improve safety.

For example, preventing cargo from moving through an outer rack opening may require a different arrangement from containing cargo behind an internal barrier.

Similarly, a system intended for uniform boxes may require further evaluation before being used with carpet rolls, long products, or mixed cargo.

Defining the problem first makes it easier to compare alternatives objectively.

2. Confirm Equipment Compatibility

Compatibility is one of the most important considerations when evaluating an industrial load-containment system.

Equipment can differ in dimensions, rail geometry, structural design, condition, and available attachment points. Even racks that look similar may have different configurations or operating requirements.

Gather the following information:

• Equipment manufacturer and model.
• Overall dimensions and opening dimensions.
• Side-rail and horizontal-bar configuration.
• Existing attachment locations.
• Rack condition and any visible damage.
• Previous repairs or modifications.
• Rated capacity and relevant manufacturer instructions.
• Any restrictions on attachments or modifications.

Photographs from several angles can help document the existing configuration. Include close-up views of the side rails, horizontal bars, openings, and potential attachment locations.

Do not assume that a proposed system can be installed on every rack of a particular general type.

If installation involves structural modifications, drilling, welding, or changes to load-bearing members, obtain the appropriate review from the equipment manufacturer or qualified engineering authority before proceeding.

3. Evaluate Cargo Characteristics and Loading Patterns

The restraint must be appropriate for the products it is intended to contain.

Evaluation Factor	Information to Collect
Product type	Boxes, carpet rolls, long products, flexible goods, or mixed cargo
Dimensions	Typical and maximum length, width, and height
Weight	Typical and maximum expected cargo weight
Shape	Rectangular, cylindrical, irregular, or flexible
Packaging	Wrapped, boxed, bundled, or unpackaged
Loading pattern	Position, stacking arrangement, and available space
Load variation	Changes between trips, shifts, or product types
Partial loads	Whether the rack routinely moves with unused space

The assessment should also consider how cargo behaves during movement. Pushing, pulling, turning, starting, stopping, and crossing floor transitions may affect the potential for shifting.

Partially loaded racks deserve particular attention because the cargo arrangement and available space may change from one trip to the next.

4. Determine Where Containment Is Needed

The required location of the restraint helps determine which system concept deserves further evaluation.

EZAIZAI LLC and 2KSteel offer two cable-based concepts for compatible Nestainer nesting-rack applications.

Cable Enclosure System (CES): Intended to provide a cable-based containment arrangement at the opening of a compatible Nestainer rack. Evaluate whether the required containment function is at the opening, whether the rack has compatible attachment locations, and whether the arrangement supports safe loading and unloading.

Internal Cable System (ICS): Intended to provide a cable barrier positioned within a compatible Nestainer rack to help contain cargo behind the barrier. Evaluate the required barrier location, available cargo space, loading sequence, attachment compatibility, and the potential for cargo or packaging to snag on the system.

CES and ICS should not be treated as interchangeable or ranked universally. The correct candidate depends on the containment problem and the particular rack and cargo configuration.

Before selection, confirm the proposed system's installation requirements, permitted applications, and operating limits with the responsible supplier and appropriate technical personnel.

5. Review Workflow and Employee Usability

A restraint system can be technically compatible with a rack yet still create problems in everyday use.

Consider how employees interact with the equipment during the entire loading and unloading cycle.

Questions include:

• Can workers load and unload products without unnecessary difficulty?
• Does the system interfere with normal access to the cargo?
• Can employees see and inspect the contained products?
• Are there pinch points, snagging hazards, or entanglement concerns?
• Is the system easy to recognize as properly positioned?
• Could workers bypass it because it interferes with normal tasks?
• Does it create additional lifting, reaching, or awkward handling?
• Can employees identify visible damage or conditions requiring removal from service?

Involve employees who perform the work, not just managers who review the equipment.

A practical evaluation should include representative users, typical cargo, normal loading patterns, and foreseeable operating conditions.

6. Establish Inspection and Maintenance Requirements

Reusable systems are designed for repeated use, but repeated use also makes inspection and maintenance important.

Before purchasing or installing a system, determine how it will be inspected and maintained.

The review should address:

• Cable condition, including visible wear, fraying, deformation, or damage.
• Brackets, connectors, and attachment points.
• Evidence of loosening, bending, corrosion, or impact damage.
• Interference with the rack or other equipment.
• Conditions that require immediate removal from service.
• Repair and replacement procedures.
• Responsibility for inspections and recordkeeping.
• Manufacturer-recommended service and replacement criteria.

Inspection intervals should be established using applicable manufacturer instructions, the facility's risk assessment, and actual operating conditions.

Employees should know what to look for and whom to notify when a concern is identified. Damaged equipment should be removed from service as appropriate until it has been evaluated and repaired or replaced.

7. Evaluate Durability and Expected Service Life

A system intended for industrial use should be evaluated against the conditions it will encounter.

These may include frequent loading cycles, impacts, abrasion, repeated handling, environmental exposure, and cleaning practices.

Request relevant technical documentation from the supplier, such as available material specifications, installation instructions, inspection guidance, and substantiated durability or test information.

Facilities should understand:

1. What conditions the system is intended to withstand.
2. What conditions are outside its intended use.
3. How wear or damage can be identified.
4. Which components can be serviced or replaced.
5. How the system should be retired from service.

8. Review Safety and Regulatory Requirements

A reusable load-containment system is one component of a broader material-handling operation.

The evaluation should consider applicable workplace safety requirements, equipment instructions, facility procedures, and any engineering approvals required for the proposed installation.

OSHA's general-industry materials-handling rule, 29 CFR 1910.176, addresses safe material storage and the prevention of sliding or collapse, as well as hazardous accumulations in storage areas.

Before implementation, verify that the proposed approach:

• Addresses the identified hazard.
• Is compatible with the equipment and its intended use.
• Does not exceed applicable equipment or cargo limits.
• Does not introduce unacceptable new hazards.
• Has the necessary installation and engineering review.
• Includes appropriate operating, inspection, and maintenance procedures.
• Does not substitute for any separate restraints required for road transport.

9. Compare Total Cost of Ownership

Purchase price is only one component of the decision.

A reusable system may reduce recurring consumable usage or labor in a suitable application, but it may also introduce acquisition, installation, inspection, maintenance, and replacement costs.

Existing process costs may include:

• Bungee cords, strapping, tape, or other consumables.
• Labor to apply and remove restraints.
• Time spent cutting and disposing of used material.
• Replacement tools and supplies.
• Documented product damage or rework associated with the process.

Reusable system costs may include:

• System acquisition.
• Installation and any necessary engineering review.
• Employee training and implementation.
• Inspection and maintenance.
• Replacement components.
• Expected repair and eventual replacement costs.

Use actual operating data wherever possible. If an estimate is uncertain, identify it as an assumption rather than presenting it as a confirmed saving.
